Why does the company's network cable have to be certified every time?

Because the default network authentication method is set.

You must connect to the wireless network manually, and then go to Control Panel >: Network and Internet & gt Network and Sharing Center, click "Set up a new connection and network" and continue to select "Connect to the wireless network manually".

Set the SSID and authentication method, manually enter the SSID of the wireless network, such as YiiFaa-Wireless in this example, select "WPA2- Enterprise" as the security type, and leave the rest blank. Click "Next" to cancel the default network authentication method, click the default setting button, cancel the option of "Authenticating the server by verifying the certificate", and click "OK". Set the authentication mode, click "Advanced Settings", check "Specify authentication mode", and finally confirm.
