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.
