Who knows that a normal computer is always disconnected from the network (intermittent connection)
Who knows that a normal computer is always disconnected from the network (intermittent connection)
The possible reasons for not opening the network industry are:
1、 Problems with network settings
This reason often occurs when it is necessary to manually specify the networking mode of IP, gateway and DNS server, and use proxy server to access the Internet. Double check your computer's network settings.
2、 Problems with DNS server
When ie cannot browse the web page, you can first try to access it with an IP address. If you can access it, it should be a DNS problem. The DNS problem may be an error in obtaining DNS during networking or the DNS server itself. At this time, you can manually specify the DNS service (the address can be the DNS server address provided by your local ISP, You can also use the DNS server address normally used in other places.) In the network properties, (control panel - network and dial-up connection - local connection - right click Properties - TCP / IP protocol - properties - use the following DNS server address). Different ISPs have different DNS addresses. Sometimes it's a problem with the router or network card. You can't connect with the DNS service of the ISP. In this case, turn off the router for a while and then turn it on, or reset the router.
Another possibility is that there is a problem with the local DNS cache. In order to improve the access speed of the website, the system will automatically store the website that has been visited and obtained the IP address into the local DNS cache. Once the website is accessed again, the IP address of the website will be directly extracted from the local DNS cache instead of through the DNS server. Therefore, if there is a problem with the local DNS cache, the website will be inaccessible. You can rebuild the local DNS cache by executing ipconfig / flushdns in run.
3、 Problems with Internet Explorer itself
When the IE browser itself fails, it will naturally affect browsing; Or ie is maliciously modified and damaged, which will also lead to inability to browse the web page. At this time, you can try to repair it with "Huangshan ie repair expert" (it is recommended to repair it in safe mode), or reinstall ie (if you encounter a problem that you can't reinstall ie, please refer to attachment 1 to solve the problem of unable to reinstall IE)
4、 Problems of network firewall
If the network firewall is not set properly, such as the security level is too high, ie is inadvertently placed in the blocked access list, wrong firewall policies, etc., you can try to check the policies, reduce the security level of the firewall, or turn it off directly to try whether it returns to normal.
5、 Network protocol and network card driver
Ie cannot be browsed, which may be caused by the damage of network protocol (especially TCP / IP Protocol) or network card driver. You can try to restart the network card driver and network protocol.
6、 Problems with hosts files
If the hosts file is modified, it will also lead to abnormal browsing. Of course, the solution is to empty the contents of the hosts file.
7、 Problems with system files
When the system files related to IE are replaced or damaged, the normal use of IE will be affected. At this time, SFC command can be used to repair it. Win98 system can execute SFC in "operation" and then scan; Win2000 / XP / 2003 executes SFC / scannow in "run" to try to repair.
Among them, when only ie can't browse the web page and QQ can go on, it is often caused by the damage or loss of files such as winsock.dll, wsock32.dll or wsock.vxd (VxD only exists in Win9x system). Winsock is an important part of TCP / IP protocol. Generally, it is necessary to reinstall TCP / IP protocol. However, XP starts to integrate the TCP / IP protocol, so it cannot be simply uninstalled and reinstalled like 98. You can use the Netsh command to reset the TCP / IP protocol to restore it to the state when the operating system was first installed. The specific operations are as follows:
Click "start running", enter the "CMD" command in the running dialog box to pop up the command prompt window, and then enter the "Netsh int IP reset C: \ resetlog. TXT" command. The "resetlog. TXT" file is a log file used to record the command execution results. This parameter option must be specified, The full path of the log file specified here is "C: \ resetlog. TXT". The result of executing this command is the same as deleting and reinstalling TCP / IP protocol.
Tip: Netsh command is a scripting tool based on the command line. You can use this command to configure and monitor the windows system. In addition, it also provides an interactive network shell program interface. For the use format of Netsh command, please refer to the help file (enter "Netsh /?" in the command prompt window) OK).
The second solution is to repair the above files. Win9x uses SFC to re extract the above files. WIN2000 / XP / 2003 uses SFC / scannow command to repair the files. When SFC / scannow cannot be used to repair the files, you can try winsockfix, a repair tool specially released on the Internet for this problem, which can be searched and downloaded on the Internet.
8、 Real time monitoring of anti-virus software
This is not often seen, but sometimes it is related to real-time monitoring, because now the real-time monitoring of anti-virus software adds the monitoring of web content. Take an example: kv2005 will cause ie to be unable to browse the web page on individual machines (many friends have encountered it). The specific performance is that as long as the web page monitoring is turned on, ie will be unable to browse the web page after about 20 minutes after the Internet is turned on. At this time, if the web page monitoring of kv2005 is turned off, everything will return to normal; After thorough reinstallation, kv2005 cannot be solved. Although not every machine installed kv2005 will have this problem, after all, the system of each machine is different, and the installed procedures are also different. But if ie can't browse the web, you should also check the anti-virus software.
9、 Problems with the application management service
When you can only go to QQ and can't open a web page, just restart it. But even if you restart, you can't open a web page after opening 7 to 8 web pages. You can only go to QQ. Sometimes Telecom often makes you disable the application management service, which can be solved. The specific reason is unknown.
10、 Infected with the virus
This situation is often reflected in the prompt in the lower left box of the IE interface when you open IE: you are opening a web page, but you haven't responded for a long time. Check the process in the task manager (enter the method, place the mouse on the taskbar, and press the right button - Task Manager - process) to see how the CPU utilization rate is. If it is 100%, it is certain that it is infected with a virus. At this time, you want to run other programs, which is just suffering. It is necessary to find out which process greedily occupies CPU resources. After finding it, it is best to record the name, and then click finish. If it cannot be finished, it is necessary to start it in safe mode, delete the Dongdong, and enter the registry. (method: start - run, enter regedit) in the registry dialog box, click Edit - find, enter the program name, and after finding it, Click the right mouse button to delete, and then search several times, which can often be completely deleted.
There are many viruses. When the anti-virus software is powerless, the only way is to delete them manually

Net software, what software dongle encryption can prevent code decompilation?
Net software, what software dongle encryption can prevent code decompilation?
According to the characteristics of. Net software, some powerful compilation tools can decompile. Net executable files and get the corresponding IL code or even source code. Even using obfuscation tools and strong naming tools can not fundamentally solve the problem. The code will still be easily decompiled by tools such as reflector. Software dongle: the codemeter and axprotector (for. Net) of WIBU have very good performance. Unlike the traditional code obfuscator, axprotector can completely prevent the decompilation of. Net assemblies (written in c#, vb.net, delphi.net, ASP. Net, etc.). Generally speaking, axprotector builds a powerful anti cracking protection barrier between the cracker and your. Net code, and generates a Windows based rather than MSIL based compatible format file. The original. Net code is completely encrypted and encapsulated in the local code. It will not be released to the hard disk at any time, which is invisible to the cracker. Different from the pure. Net encryption software, axprotector and codemeter hardware dongle are used with packages. More rigorous key management and the most advanced AES, RSA, ECC and other encryption algorithms are used to store or transmit keys to ensure communication security The. Class generated after compiling net code contains all the information in the source code (excluding comments), especially when debugging information is saved in it. Therefore, a. Class file compiled in the normal way can be decompiled very easily. Generally, software developers will use a tool called obfuscator. The function of obfuscator is to confuse the compiled code, so that it cannot be decompiled or the decompiled code is confused and difficult to understand. Because the obfuscator only confuses the method name or process, but can not prevent the source code from being decompiled, the function of the obfuscator only increases the difficulty of decompilation, and the final result is to treat the symptoms rather than the root cause. It is almost transparent to some people who master tools. Axprotector is a true. Net software encryption software that encrypts source code and prevents decompilation. Axprotector encrypts the. Net original code, which cannot be restored to the hard disk at any time. The. Net code encrypted with axprotector can only be decrypted in memory through axprotectorclass and returned to the program for execution when the program calls or executes a certain function. It can be encrypted immediately after running. This function of random encryption and on-demand decryption of the original code can well prevent the decompilation of. Net programs and the removal of API encryption points. It effectively ensures the execution efficiency and security of the source code.

What is S4 encryption lock
What is S4 encryption lock
Encryption lock, also known as dongle, is an intelligent tool with software protection function provided for software developers. It includes a hardware installed on the computer parallel port or USB port, and a set of interface software and tool software suitable for various languages.
Encryption lock is based on hardware protection technology. Its purpose is to prevent the illegal use of intellectual property rights through the protection of software and data.
S4 encryption lock is a reflection on generation 4 encryption lock
S4 encryption lock, which we call deep thinking IV encryption lock, is an intelligent lock product of Beijing deep thinking lock company (www.sense. Com. CN). It is characterized by transplanting part of the PC software source code into the lock (32K or 64K). This effect is that if you don't know the code in the lock, It is impossible to pirate the software encrypted by S4:) even if explosive force modifies the encrypted file, it will cause problems such as incomplete function, memory or address error during execution
A very powerful hardware encryption product

Do you need to update the software and hardware of dongle and Guanglianda in 2013
Do you need to update the software and hardware of dongle and Guanglianda in 2013
A hardware device similar to USB flash disk, named encryption lock, later developed into a popular industry term for software protection. "Encryption dog" is an encryption product with the combination of software and hardware inserted into the parallel port of the computer (the new encryption dog also has USB port). Generally, there are dozens or hundreds of bytes of nonvolatile storage space for reading and writing. Now the newer dog also includes a single chip microcomputer. Software developers can check whether the dongle is plugged into the interface through data exchange between the interface function and the dongle (i.e. reading and writing the dongle); Or directly encrypt your own EXE file (commonly known as "package") with the tool attached to the dongle. In this way, software developers can set multiple software locks in the software and use the software dog as the key to open these locks; If the dongle is not inserted or does not correspond to the dongle, the software will not execute normally. The dongle realizes encryption by exchanging data with the dongle during software execution. The built-in single chip microcomputer circuit (also known as CPU) makes the dongle have the processing ability of judgment and analysis, and enhances the active anti decryption ability. This encryption product is called "intelligent" dongle. The built-in MCU of the dongle contains algorithm software dedicated to encryption. After the software is written into the MCU, it can no longer be read out. This ensures that the dongle hardware cannot be copied. At the same time, the encryption algorithm is unpredictable and irreversible. The encryption algorithm can convert a number or character into an integer, such as dogconvert (1) = 12345, dogconvert (a) = 43565. Dongle is an intelligent software protection tool for software developers. It includes a hardware installed on the computer parallel port or USB port, and a set of interface software and tool software suitable for various languages. Dongle is based on hardware protection technology. Its purpose is to prevent the illegal use of intellectual property rights through the protection of software and data.
[edit this paragraph] working principle
Working principle of dongle: the dongle realizes encryption by exchanging data with the dongle during software execution. The built-in single chip microcomputer circuit (also known as CPU) makes the dongle have the processing ability of judgment and analysis, and enhances the active anti decryption ability. This encryption product is called "intelligent" dongle. The built-in MCU of the dongle contains algorithm software dedicated to encryption. After the software is written into the MCU, it can no longer be read out. This ensures that the dongle hardware cannot be copied. At the same time, the encryption algorithm is unpredictable and irreversible. The encryption algorithm can convert a number or character into an integer, such as dogconvert (1) = 12345, dogconvert (a) = 43565. Below, we give an example to illustrate the use of MCU algorithm. For example, there is a sentence in a program: a = FX (3). The program obtains the value of variable a according to constant 3. Therefore, we can rewrite the original program like this: a = FX (dogconvert (1) - 12342). Then the constant 3 will not appear in the original program, and dogconvert (1) - 12342 is used. In this way, only the software writer knows that the constant actually called is 3. If there is no dongle, the dogconvert function cannot return the correct result, and the result formula a = FX (dogconvert (1) - 12342) will certainly not be correct. This encryption method that makes pirated users unable to get the use value of the software is milder, more hidden and more difficult for decryptors to figure out than the encryption method that warns and stops when illegal use is found. In addition, the dongle also has a read-write function, which can be used to read and write the memory inside the dongle. So we can also write 12342 in the above formula to the dog's memory, so that the value of a completely depends on the results of dogconvert() and dogread() functions, making decryption even more difficult. However, generally speaking, the algorithm difficulty of dongle MCU is lower than that of some public encryption algorithms, such as DES, because decryptors have to face many difficulties before touching the dongle algorithm
[edit this paragraph] development process
With the development of decryption technology, MCU dongle is gradually eliminated by the market because of its simple algorithm, small storage space and easy to be copied by hardware. The domestic dongle manufacturers led by Beijing Rainbow World Information Technology Co., Ltd. have developed the fourth generation dongle - "smart card" dongle, which has better stability, larger storage space (up to 64K) and can effectively prevent hard cloning. With its original "code transplantation" principle, it has been widely used by large domestic commercial software developers such as Kingdee, UFIDA, CAXA, Guanglianda, magic tricks Adopted by Luban. Taking Honggou, the world's first smart card encryption lock, as an example, this paper briefly introduces the principle of "code transplantation"“ The encryption principle of "code migration" is a new and reliable software protection model. Its working principle is that some codes in the software are compiled and "transplanted" into the encryption lock hardware, and there is no copy of this code in the software. In this software protection scheme, the key codes and data of PC application software "disappear" and are safely transplanted to the hardware of elite type IV encryption lock for protection. When needed, the application software can instruct the elite IV to run the key codes and data in the hardware and return the results through the function call engine, so that all the functions of the whole software can still be completed. Because there is no copy of these codes and data on the PC side, the decryptor has no way to guess the algorithm or steal the data, which greatly ensures the security of the whole software system. In short, elite IV provides a set of trusted solutions to theoretically ensure the security of software encryption.
[edit this paragraph] programming language that can be protected
The programming language that dongles can protect is constantly changing with the development of computer hardware and operating system. In the 1980s, personal computers were mainly at, 286 and other models. The operating system of personal computer is mainly DOS, and the operating system of enterprise server mainly uses Novell Netware. Engineers developing dongle protection software need to encrypt exe files under DOS by modifying INT21 and int10 methods of DOS, or provide encryption for Turbo C, FORTRAN, basic and other programming languages by providing specific API methods. Sometimes engineers who develop dongle protection software may directly write. Com files using DOS debug. Since then, the operating system of personal computer has experienced the upgrading of windows, Windows 95, Windows 2000, Windows NT and XP. The means of protecting exe files has also changed from DOS resident program to writing VXD, Sys and other methods. Programming languages also include: MASM, Turbo C, VC, watcom C for NetWare, watcom C for x86, NDP C for x86, NDP FORTRAN, Visual FoxPro, clipper, LISP for AutoCAD, etc. With the continuous enhancement of hardware processing ability of dongle and the popularity of computer USB port, the protection of software gradually depends on the general encryption algorithm, rather than the encryption programming skills of encryption software. The use of dynamic link libraries and controls can meet the protection needs of most programming tool software. Dongle manufacturers are also liberated from customizing APIs for different programming tools and software one by one.

The network is not connected
The network is not connected
Step 1: check whether the driver of the wireless network card is installed correctly. Right click "my computer" - properties - hardware - Device Manager to check whether there are network devices marked with question marks or exclamation marks. If so, it indicates that the wireless network card driver is not installed correctly. Use the "hardware detection" function of Jinshan guard to detect the wireless network card model, and then use the computer with network to download the corresponding driver and copy it to the problem computer for installation( If the notebook can be connected to the wired network, you can directly use the "install driver" function of Jinshan guard to detect and repair the driver).
Step 2: open Jinshan guard, click the "reinstall system" button on the main interface, open the "hardware detection" function below, click "network card", you can see your local network card and wireless network card information, write down the model of wireless network card, search the driver on the computer with network for download, and then install on the local computer.
If the driver is installed correctly, the problem that the notebook wireless network is not connected is generally caused by the incorrect Internet access setting of the wireless network. Adjust the laptop wireless Internet settings according to the following conditions.
To solve the problem that the computer wireless network cannot be connected, step 1: if the prompt "Windows cannot configure this connection" appears when you click refresh the network list, open the "system optimization" function of Jinshan guard, click the "startup acceleration" tab, click "service items", and select "display items prohibited from Startup" in the lower left corner, Then find "wireless zero configuration" in the list and click "on" on the right. Then, in start run, enter net start wzcsvc and press enter. The symptoms of notebook wireless network connection failure can be solved.
To solve the problem that the computer wireless network cannot be connected, step 2: if the wireless network cannot be searched, you must check whether the wireless network hard switch of the notebook is turned on. After turning on the hardware switch, some notebooks also need to use the FN key + F5 key in the lower left corner of the keyboard to turn on (the specific models are different, and the wireless graphics can be found in the blue function icon at F1-F12). Some Lenovo notebooks need to turn on the power management software to make the wireless switch on the keyboard work normally, so make sure to install power management, and turn on the power management utility in Jinshan guard's "power on acceleration" - "startup item" (also select "display disabled items" in the lower left corner).
Step 3: if the switch is turned on but the wireless network cannot be found, right-click the wireless network icon in the tray at the lower right corner, click "open network connection", then right-click the wireless network icon in the open window, click "properties", and click the "wireless network configuration" tab, Check "OK" before "configure my wireless connection settings with windows", and open "view available wireless connections" again to see whether it is possible.
To solve the problem of computer wireless network connection failure, step 4: if the wireless network can be found, but the web page cannot be opened after connection, open the properties of wireless network connection, find "Internet Protocol (TCP / IP)" in the middle white box under the "general" tab, select it, click "properties" to see whether the IP address and DNS configuration are correct, It is generally set to "automatically obtain IP address" and "automatically obtain DNS server address".
Postscript: if you follow the above four steps, you should be able to solve the problem that the computer wireless network is not connected.

Why should advertising company management software use dongle!!
Why should advertising company management software use dongle!!
Customers who use the management software of Feiyang power advertising company often ask,
What's the use of dongles? What is the dongle used for? Why not use e-Cert?
In 2016, the management software of Feiyang power advertising company decided to use dongles to manage user data
Therefore, for users of advertising company management software purchased before 2016, it is recommended that you contact customer service and reissue the dongle
So today, Xiaobian will specifically explain the benefits of using dongles
Dongle benefits:
1. It is convenient to replace the computer
If, when the customer is on the host computer, there are some hardware failures. Just pull out the dongle
Then, replace it with a new computer, and you can continue to use it, which is more safe and reliable
2. Simple operation mode
At the same time, the use method of the dongle is relatively simple. It can be directly inserted into the USB interface of the computer
3. Easy to restore data
If data is lost when using dongle management software. Copy data directly from the cloud.
Then, restore the data directly, and then plug in the dongle to continue to use. It is very convenient and simple.
Disadvantages of e-Cert:
1. The host computer cannot be replaced at will
If we use electronic certificate to use advertising company management software and replace the host computer, it will become very troublesome.
Because under normal circumstances, the electronic certificate is tied with the server computer, and the host computer cannot be changed at will( Just reinstall the computer and it won't be affected)
2. Electronic certificate data is easy to be lost
Generally, the certificate will not be lost, but. If the customer is deleted by mistake, the electronic certificate data is damaged, etc
It can't be used normally. Therefore, generally using electronic certificate is a very troublesome thing.

How do java programs do dongles
How do java programs do dongles
As we all know, Java provides a very convenient development platform for the development language, but the developed programs can be easily transplanted on different platforms. Now more and more people use it to develop software. Java has one convenient aspect, but it also brings a worry to developers. This is that there are few protection methods, and most of them are not easy to use. In this way, the programs developed by themselves are easy to be copied and taken as their own. Generally, Most people use the Java obfuscator to scramble the developed program so that there is no way to decompile and view the source code, but this method is easy to find relevant software on the Internet to rearrange, so this hybrid can only control some people who can't move your software, For some people who master the tools, it is almost transparent. There is also the use of hardware encryption locks, but the hardware encryption locks provided by most companies only provide some DLL connections or simple API calls. As long as they are decompiled, it is easy to remove some API calls. In this way, the hardware encryption locks will not work, but is there a better way now? The shell encryption tool provided by hasp HL encryption lock provided by Aladdin company in Israel has a function called data encryption, which can well prevent the removal of API calls. As you all know, the protection principle of hardware encryption lock is to closely combine your encrypted software with the hardware of encryption lock, Moreover, it is not easy to get rid of the original call, so as to ensure that your software is not pirated. At the same time, this method is also easy to be mastered by programmers. It takes only a few minutes to protect a software, Here is a brief introduction to his principle: use the shell tool provided by Aladdin company to call your Java interpreter for encryption, that is, if you want to use this interpreter, you need to have a specific encryption lock, Then we use the content encryption in the shell encryption tool provided by it to process your written Java program as a file and encrypt it. This encryption adopts the aes128 bit algorithm, so that the encrypted data file - your software can only be interpreted by your protected Java interpreter, However, if there is no encryption lock, you can't run your software, so as to truly protect your software.

Can I share dongles over the Internet
Can I share dongles over the Internet
A friend has a dongle, but it's impossible to borrow it. Can you share his dongle through the Internet??
Due to the security design requirements of the dongle itself, Internet sharing is not allowed, which violates the original intention of the security design of the dongle. The main reasons are as follows:
The dongle is usually designed as a security scenario for the local USB or serial port, and can only be bound with some hardware parameters of the local computer to realize security control.
The software calculates the security key through the dongle to verify the user's identity. Its main verification parameters are CPU ID and other unique hardware parameters, so as to ensure that the computer using the dongle can only use some content with security requirements.
Therefore, the dongle cannot be shared through the Internet.

Fault diagnosis method of LAN unable to access the Internet
Fault diagnosis method of LAN unable to access the Internet
A case in the book: the connection status of a computer in the LAN only sends data, while the received data packet is 0. According to the analysis of fault phenomenon, the cause of the fault may be computer fault, network cable fault, switch fault or network configuration fault. Firstly, connect the user's network cable to another normal computer for test. It is found that it can be connected. It seems that the fault comes from the computer itself. Then check the network card driver and there is no abnormality. After replacing the network card with the replacement method, the fault disappears. It seems that the network failure is caused by the network card failure. You can also follow the above step-by-step inspection to find out the cause of the fault and solve the fault as soon as possible.
Fault diagnosis method of LAN unable to access the Internet
The diagnosis method for a single computer in the LAN is as follows:
Step 1: first determine whether a single computer can't access the Internet or all computers in the LAN can't access the Internet. If a single computer can't access the Internet, in Windows
In XP / 2000 operating system, click Start / all programs / Accessories / communication / network connection to open the "network connection" window (you can also right-click the network neighborhood icon and select the "properties" command),
Step 2: then check the status of "local connection". If the icon of the local connection is that two small computers flash and the prompt "connected", it means that the line from the switch hub to the computer is normal, and the network card can basically work normally. The failure to access the Internet is caused by improper operating system settings or software restrictions. Use the ping command to Ping the remote host to see if it can ping. If it can ping, it indicates that the network connection is normal, and then check the firewall settings and proxy server settings in the computer.
Step 3: if Ping fails, it may be a network protocol configuration problem. Check the computer IP address, gateway, DNS and other configurations.
Step 4: if the local connection icon in the "network connection" window is gray, it means that the local connection (network card) is disabled. At this time, just double-click the local connection icon to re enable it.
Step 5: if the local connection icon in the "network connection" window indicates that "the local cable is pulled out", it indicates that one end of the network cable connector from the switch or hub to the user network card is loose or there is a problem with the network cable. Then check whether the network cable is in good contact. If it is in good contact, then check the network cable.
Local connection restricted or no connection
1. Local connection: start / set / network connection / click local connection / properties / general / double click "Internet Protocol (TCP / IP)" / properties / select the following IP address (for reference, you can fill it in separately):
IP address: 192.168.0.2
Subnet mask: 255.255.255.0
Default gateway: 192.168.0.1.
Use the following DNS server address preferences: 1.1.1.1
Finally, click OK.
2. Broadband connection: right click broadband connection / properties / network / select to automatically obtain IP address / OK.

What are the reasons for limited network connectivity
What are the reasons for limited network connectivity
WiFi network is limited or unable to connect, which is mainly caused by poor hardware compatibility between the router and the connected device, improper connected device driver and more cache during use. Therefore, network restriction means that the connection is established but the network cannot be accessed. First, you can eliminate the PC wired or wireless connection failure.
When the network connection is limited or there is no connection, you must keep calm and orderly investigate the causes of the problem in order to solve the problem more quickly.
Extended data
When the connection mode is wired, find the local connection, disable it and then enable it, or plug in and out the network cable; When the connection mode is wireless connection, find the wireless network connection, disable it and then enable it to see whether the network is limited due to data blocking or unstable network card operation;
It is also possible that the IP address is wrong and unable to communicate with the server, resulting in limited network. Therefore, you can reset an available static IP or automatically obtain the IP address.

The network cannot be connected!
There are many possibilities. You can try the following steps. If not, I can't help it.
1、 If you are a static IP, you can skip this step. If you obtain the address through DHCP, first check your IP address and the network segment in which the IP is located. (the method of checking the local address starts -- run -- CMD -- ipconfig / all. At this time, you can see your IP address. Here, assume that the local IP is 192.168.1.100, the mask is 255.255.255.0, the gateway is 192.168.1.254, and the preferred DNS is 192.168.1.11, Alternate DNS is 192.168.1.12). After you know the IP address, you can choose to use the following IP address through network neighborhood - properties - local connection - properties - internet protocol (TCP / IP): enter any one of 192.168.1.2-192.168.1.253 (as long as it does not conflict with other IP addresses), 255.255.255.0 for mask, 192.168.1.254 for gateway, 192.168.1.11 for DNS, Fill in 192.168.1.12 for standby DNS, and then click OK. If not, the next step.....
2: Check whether your network cable is plugged in. Pull out both ends of the crystal head of the network cable and plug it tightly again. At this time, if you are a static IP, open the browser to see if you can surf the Internet. If not, please skip this step to see "three"; If you obtain IP through DHCP, you can check your IP first through the method in step 1, or wait a few seconds to see if there is an exclamation mark in the small local connection icon in the lower right corner and show that the local connection is restricted. If not, Congratulations, you can continue surfing the Internet again; If you still can't....
3: At this time, you can cut off the power supply of the router or switch (depending on the network environment, families or small companies with only a few computers are generally routers, and companies with more than 10 computers are generally switches + routers), and plug it in after one or two minutes, At this time, look at the small local connection icon in the lower right corner to see if there is an exclamation mark and show that the local connection is restricted. If not, congratulations. If it still appears, don't lose heart. Please continue to look down.
4: At this time, you should consider whether there is something wrong with your network cable, poor contact of the crystal head, problems in the quality of the line and other factors will lead to packet loss or packet failure in your line transmission. If you have tools, you can use tools to measure the network cable to see whether the line is smooth. If the line is smooth and normal, Then please skip this trick; If it is not unobstructed, you can clamp the crystal heads at both ends with wire stripping pliers, or make the crystal head again, and then insert the wire. The problem should be solved.
5: The IP is correct, the router and switch are powered off and re plugged, and the network cable is also good. Why can't you access the Internet? It's urgent!! Hehe, don't worry. In this case, you can see whether the people around you can surf the Internet, or whether other machines can surf the Internet. If they can, there are two possibilities for why you can't surf the Internet. One is that your computer is poisoned (the possibility is very small), and the other is that your network card is faulty (the possibility is very high). There's no way. Try changing a network card!

Reasons and solutions for not being able to connect to the Internet after being connected to the network:
Reasons and solutions for not being able to connect to the Internet after being connected to the network:
(1) Reason:
(1) There may be a DNS error that prevents internet access.
(2) There may be an ARP virus in the LAN. It leads to network blocking and inability to access the Internet.
(2) Treatment method:
(1) The first reason is to fill in DNS again. The specific steps are as follows:
1. Open the "run" dialog box (or press Win + R), enter the command "CMD" to enter the MSDOS interface.
2. Enter the command "ipconfig / all" in MSDOS interface, and the local gateway and DNS information can be viewed in the displayed result page.
3. Open control panel, double-click network connection, then right-click local connection and select properties.
4. Check "manually set DNS" to set DNS for the current connection. After setting, check whether you can surf the Internet normally again.
(2) The processing method for the second reason: it can be completed by static binding ARP operation. The specific steps are as follows:
1. Install 360 security guard on the computer, open 360 security guard, select "360 Trojan firewall" in "complete functions", click enable ARP firewall, and click OK in the pop-up prompt dialog box. Then restart the computer.
2. After the computer restarts, 360 security guard will remind that ARP protection is successful. Click on the details, you can intuitively see the communication situation of the network. So far, the computer can surf the Internet normally and safely

A computer is a machine that processes data according to a series of instructions using the principles of electronics. The computer can be divided into two parts: software system and hardware system. The first computer was the ENIAC general-purpose electronic computer born at the University of Pennsylvania on February 15, 1946.
People call a computer without any software as bare metal. With the development of science and technology, there are some new computers: biological computer, photon computer, quantum computer and so on. On May 24, 1954, the transistor electronic computer was born.
The types of input and output devices of the first generation computers were very limited. The usual input device is a punch card reader, which is used to import instructions and data into memory; The output device used to store the results is generally tape. With the progress of science and technology, the richness of input and output equipment has been improved. Take the personal computer as an example: the keyboard and mouse are the main tools for users to input information directly to the computer, while the display, printer, loudspeaker and headset return the processing results. In addition, there are many input devices that can accept other different kinds of information, such as digital cameras that can input images.
There are two types of input and output devices worth noting: the first is secondary storage devices, such as hard disks, optical discs or other devices with slow speed but high capacity. The second is computer network access equipment. The direct data transmission between computers through them greatly improves the value of computers. Today, the Internet has enabled tens of millions of computers to transmit various types of data to each other.

Prompt no network connection
Prompt no network connection
Check that there is a yellow exclamation mark in the lower right corner of the network card. If so, it means that your network card is not normally connected to the computer.
In the first case, check whether your network cable and network cable connector are normal. In the second case, check whether your switch and your computer are connected properly. In the third case, check whether the PCI slot of the computer motherboard is normal. Finally, check whether the network card is abnormal and whether the network card driver is abnormal.
There are the following possibilities
1. The wireless router does not automatically dial the cat or is not connected. You are only connected to the nearest router
Solution: enter 192.168.1.1 or 192.168.0.1 in the address bar of the browser to open the routing management, check whether the WAN end is not connected, and reset the router dial-up.
2. No DNS address is set for wireless routing and no DNS address is set for this machine
3. The probability of network cable problems is very small
Solution to unavailable wireless network connection:
one
First, consider the hardware switch of the wireless network. Some notebooks have this switch. If you turn it off, no matter how you toss the computer, you can't turn on the wireless network.
The following figure shows the wireless network switch of Lenovo y470:
two
Ninety percent of the notebooks contacted by the author are due to the following reasons:
Almost all notebooks are provided with FN key to control the wireless network switch. This function is similar to the hardware wireless network switch mentioned in the first step. If it is turned off, the problem shown in the title will also occur.
Some notebooks use this shortcut key to turn off the wireless network by default. For example, ASUS does not know that it has been turned off, so it can't turn on the wireless network anyway. This is the problem of most people.
For example, Lenovo y470 can turn on and off the wireless network by using FN + F5
If you want to use the shortcut key of notebook, there are many important preparations. If you don't make these preparations, the closed wireless network can't be turned on anyway. Please see the next step for specific preparations.
The step y470 shortcut keys are shown in the following two figures:
three
In the previous step, if you want to use the shortcut key "FN + wireless network icon", first, you need to install some drivers and application software that come with your laptop. Because, unlike other keys on the keyboard, FN needs a special driver to work. Different brands of notebooks use different software.
The author here provides the software required by the following two brands. Please go to the official website to download:
Lenovo: network card driver, wireless network card driver, power management software (energy management)
ASUS: network card driver, Qualcomm Atheros wireless network card driver and application program, ATK hotkey tool program
four
All the switches to be turned on and the software to be installed are pressed, but if it still doesn't work, it depends on the system service,
Control panel - system and security - management tools - services,
Please make sure that the following five service statuses are all "started":
Network Connections、
Network List Service、
Network Location Awareness、
Network Store Interface Service、
WLAN autoconfig (especially this service)
As shown below:
five
If the wireless network is still unavailable, select "open network and sharing center" -- "change adapter settings" -- "wireless network connection" -- right click "enable"
At this point, the wireless network should be able to be used normally. If not, it should be sent to the store to test whether the wireless network hardware is normal.
END
Several important problems after successfully connecting to the wireless network:
Q: the wireless network has been successfully connected. Why can't you open the web page?
A: Please select "open network and sharing center" -- "change adapter settings" -- "wireless network connection" -- right click "properties" -- "Internet Protocol version 4 (TCP / IPv4). Double click to open it and select all to get it automatically"
Q: what is the difference between a network card driver and a wireless network card driver?
A: the network card driver is the driver of the interface you connect to the network cable, and the wireless network card is the driver of the wireless card built in the notebook.
Q: are there any quick solutions to general network problems?
A: right click the network icon and select "troubleshooting". The system will automatically solve some basic network problems; Or CMD open the command prompt box and enter: SFC / scan now. The basic problems in the whole system will be automatically scanned and repaired.
——————————————————————————————————————————————————————————
1. Check whether the wireless network card driver is installed correctly
First, check whether the driver of the wireless network card is installed correctly. You can right-click "my computer" - properties - hardware - Device Manager to check whether there are network devices marked with question marks or exclamation marks. If so, it indicates that the wireless network card driver is not installed correctly. You can use the "hardware detection" function of Jinshan guard to detect the wireless network card model, and then use the computer with network to download the corresponding driver and copy it to the problem computer for installation.
Open Jinshan guard, click the "reinstall system" button on the main interface, open the "hardware detection" function below, click "network card", you can see the information of local network card and wireless network card, write down the model of wireless network card, search the driver on the computer with network for downloading, and then install on the local computer.
If the driver is installed correctly, the problem that the notebook wireless network is not connected is generally caused by the incorrect Internet access setting of the wireless network.
2. Turn on the notebook wireless network service
If the prompt "Windows cannot configure this connection" appears when you click to refresh the network list, open the "system optimization" function of Jinshan guard, click the "startup acceleration" tab, click "service item", select "display disabled items" in the lower left corner, and then find "wireless zero configuration service" in the list, Click "open" on the right. Then, in start run, enter net start wzcsvc and press enter. The symptoms of notebook wireless network connection failure can be solved.
3. Check whether the wireless network hard switch is on
If the wireless network cannot be searched, check whether the wireless network hard switch of the notebook is on. After turning on the hardware switch, some notebooks also need to use the FN key + F5 key in the lower left corner of the keyboard to turn on (the specific models are different, and the wireless graphics can be found in the blue function icon at F1-F12). Some Lenovo notebooks need to turn on the power management software to make the wireless switch on the keyboard work normally, so make sure to install power management, and turn on the power management utility in Jinshan guard's "power on acceleration" - "startup item" (also select "display disabled items" in the lower left corner).
4. Open view available wireless connections
If the switch is turned on but the wireless network is still not found, right-click the wireless network icon in the tray at the lower right corner, click "open network connection", then right-click the wireless network icon in the open window, click "properties", click the "wireless network configuration" tab, check "configure my wireless connection settings with windows" and then "OK", Open view available wireless connections again to see if you can.
5. Check whether the IP address and DNS configuration are correct

The network is not connected
The network is not connected
1) If it is a broadband problem, first connect the broadband cable directly for test. If it is a broadband problem, contact the broadband customer service for solution.
2) If it's a router problem, if it can be used, it can't be used for the time being. My own practice is to cut off the power supply of the router and plug it in. I'll see later. If yes, restore the factory settings and use the new settings (this is sometimes caused by the slow or failure of the router to find the IP address on the premise of correct physical connection, which does not mean that the router is broken).
If it cannot be solved, it is recommended to call the customer service of the router. They have telephone online guidance. When I encounter problems that I can't solve, it is very useful to consult their suggestions. They will give correct suggestions for your setting or operation.
3) If you turn off the wireless switch, just turn it on. If it is a wireless connection with software, it is normal that the software is not easy to use and often has problems. There is no better way. Use a router. In addition, the network card driver is not or inappropriate. Is there a problem with the network cable interface or network cable.
4) If it is caused by a system problem, it is recommended to restore the system or reinstall it.
Use the system restore method provided with the system:
System restore provided by the system: "start" / "program" / "accessories" / "system tools" / "system restore", click "restore my computer to an earlier time", press next, and you will see a dark date on the date page, that is, the restore point. After you select it, click Next restore (win7810 restore the system, right-click the computer and select properties, Select system protection and system restore on the right. Just follow the steps. If there is restore software, you can also restore the system with software).
5) If you have any questions, please ask me.

Solution to unavailable wireless network connection:
one
First, consider the hardware switch of the wireless network. Some notebooks have this switch. If you turn it off, no matter how you toss the computer, you can't turn on the wireless network.
The following figure shows the wireless network switch of Lenovo y470:
two
Ninety percent of the notebooks contacted by the author are due to the following reasons:
Almost all notebooks are provided with FN key to control the wireless network switch. This function is similar to the hardware wireless network switch mentioned in the first step. If it is turned off, the problem shown in the title will also occur.
Some notebooks use this shortcut key to turn off the wireless network by default. For example, ASUS does not know that it has been turned off, so it can't turn on the wireless network anyway. This is the problem of most people.
For example, Lenovo y470 can turn on and off the wireless network by using FN + F5
If you want to use the shortcut key of notebook, there are many important preparations. If you don't make these preparations, the closed wireless network can't be turned on anyway. Please see the next step for specific preparations.
The step y470 shortcut keys are shown in the following two figures:
three
In the previous step, if you want to use the shortcut key "FN + wireless network icon", first, you need to install some drivers and application software that come with your laptop. Because, unlike other keys on the keyboard, FN needs a special driver to work. Different brands of notebooks use different software.
The author here provides the software required by the following two brands. Please go to the official website to download:
Lenovo: network card driver, wireless network card driver, power management software (energy management)
ASUS: network card driver, Qualcomm Atheros wireless network card driver and application program, ATK hotkey tool program
four
All the switches to be turned on and the software to be installed are pressed, but if it still doesn't work, it depends on the system service,
Control panel - system and security - management tools - services,
Please make sure that the following five service statuses are all "started":
Network Connections、
Network List Service、
Network Location Awareness、
Network Store Interface Service、
WLAN autoconfig (especially this service)
As shown below:
five
If the wireless network is still unavailable, select "open network and sharing center" -- "change adapter settings" -- "wireless network connection" -- right click "enable"
At this point, the wireless network should be able to be used normally. If not, it should be sent to the store to test whether the wireless network hardware is normal.
END
Several important problems after successfully connecting to the wireless network:
Q: the wireless network has been successfully connected. Why can't you open the web page?
A: Please select "open network and sharing center" -- "change adapter settings" -- "wireless network connection" -- right click "properties" -- "Internet Protocol version 4 (TCP / IPv4). Double click to open it and select all to get it automatically"
Q: what is the difference between a network card driver and a wireless network card driver?
A: the network card driver is the driver of the interface you connect to the network cable, and the wireless network card is the driver of the wireless card built in the notebook.
Q: are there any quick solutions to general network problems?
A: right click the network icon and select "troubleshooting". The system will automatically solve some basic network problems; Or CMD open the command prompt box and enter: SFC / scan now. The basic problems in the whole system will be automatically scanned and repaired.
——————————————————————————————————————————————————————————
1. Check whether the wireless network card driver is installed correctly
First, check whether the driver of the wireless network card is installed correctly. You can right-click "my computer" - properties - hardware - Device Manager to check whether there are network devices marked with question marks or exclamation marks. If so, it indicates that the wireless network card driver is not installed correctly. You can use the "hardware detection" function of Jinshan guard to detect the wireless network card model, and then use the computer with network to download the corresponding driver and copy it to the problem computer for installation.
Open Jinshan guard, click the "reinstall system" button on the main interface, open the "hardware detection" function below, click "network card", you can see the information of local network card and wireless network card, write down the model of wireless network card, search the driver on the computer with network for downloading, and then install on the local computer.
If the driver is installed correctly, the problem that the notebook wireless network is not connected is generally caused by the incorrect Internet access setting of the wireless network.
2. Turn on the notebook wireless network service
If the prompt "Windows cannot configure this connection" appears when you click to refresh the network list, open the "system optimization" function of Jinshan guard, click the "startup acceleration" tab, click "service item", select "display disabled items" in the lower left corner, and then find "wireless zero configuration service" in the list, Click "open" on the right. Then, in start run, enter net start wzcsvc and press enter. The symptoms of notebook wireless network connection failure can be solved.
3. Check whether the wireless network hard switch is on
If the wireless network cannot be searched, check whether the wireless network hard switch of the notebook is on. After turning on the hardware switch, some notebooks also need to use the FN key + F5 key in the lower left corner of the keyboard to turn on (the specific models are different, and the wireless graphics can be found in the blue function icon at F1-F12). Some Lenovo notebooks need to turn on the power management software to make the wireless switch on the keyboard work normally, so make sure to install power management, and turn on the power management utility in Jinshan guard's "power on acceleration" - "startup item" (also select "display disabled items" in the lower left corner).
4. Open view available wireless connections
If the switch is turned on but the wireless network is still not found, right-click the wireless network icon in the tray at the lower right corner, click "open network connection", then right-click the wireless network icon in the open window, click "properties", click the "wireless network configuration" tab, check "configure my wireless connection settings with windows" and then "OK", Open view available wireless connections again to see if you can.
5. Check whether the IP address and DNS configuration are correct

What if the network is connected but can't get on the network
What if the network is connected but can't get on the network
First of all, you should confirm whether you have really connected to the network. According to my experience, in Windows 7 system, sometimes even if the network icon in the lower right corner shows that it is connected, it is not connected. At this time, you need to open this icon, disconnect it first, and then reconnect it.
If the computer is connected to the Internet and still can't access the Internet, you can reset the browser. Here, I only take IE browser as an example. If you use another browser without reset option, you can uninstall and reinstall. Ie cannot be uninstalled, so it can only be reset.
Open IE browser, click the tools menu in the menu bar, and then click the Internet option at the bottom
In the Internet Options page, click the Advanced tab with the mouse to switch to the Advanced tab. There is a reset button at the bottom. You can click this reset button to reset the browser.
You'd better delete all personal settings and custom browser settings. Including personal data, cache, cookies, etc. Select the previous check box and click OK to start the reset. The browser needs to be restarted after reset.
The problem of the browser itself has been solved. If it still doesn't work, we should consider whether firewall software prevents the browser from accessing the network. There are many kinds of third-party firewalls, and there are various ways to unlock them. Here, I will only take the firewall software of the system as an example. First open the control panel and click windows firewall.
In windows firewall, click Advanced settings in the left navigation bar. As shown in the figure, we want to see if the firewall prohibits your browser from accessing the network. Of course, the browser here does not refer to ie, which is unimpeded in Windows system.
Find your browser in this inbound and outbound list to see if it has been disabled. If it is prohibited, right-click the browser and modify it to trust software in the properties. Then see if the status behind the browser has become allowed. After it becomes allowed, close the firewall and open the browser to see if the Internet is normal.
Or you can use a more worry-free method. If you are just an ordinary user and there is no top secret information in the computer, you can turn off the firewall of the system. It's really useless for ordinary users. I'm an ordinary user. I've been online for more than ten years and haven't encountered hacker attacks. So you can turn it off.
After using the above methods, if you still can't connect to the network. The possible reason is that some security software prohibits you from accessing relevant websites. If your computer has been used by others, you should consider this problem. There are many such software, but the operation is generally very simple. It can be set in the site interception function. I won't repeat it here. Then the problem is not easy to deal with. The reason that can be considered is that the virus file has seriously damaged the relevant files of the system
If none of the above methods can solve the problem, it will be difficult to solve the problem. The reason that can be considered is that the virus files have seriously damaged the relevant files of the system. I think it will take more time to repair the system through various optimization and repair software than to reinstall the system, which is not cost-effective. Therefore, when you reach this level, I suggest you reinstall the system. After reinstallation, all settings are default. There is no problem. Even if there is a problem, it is also the problem of your network service provider.

1. The parallel port encryption dog needs to be installed with driver, and there is no parallel port encryption lock without driver; The reason why you think it is driveless is that the software manufacturer packaged the driver into the software package. You have installed the driver of encryption lock when installing the software;
2. It may be connected to the encryption lock through the print card, and the power supply voltage is insufficient, so that the encryption lock cannot be recognized. If possible, it is recommended to replace a print card (i.e. the card converted to parallel port) and try it;
3. If not, it is recommended to contact the software manufacturer and recommend that it replace the USB dongle. Now the parallel port lock is almost not used. It is an antique product ~ hehe
