The laptop can be connected to the Internet, but the picture shows that it cannot be connected. This afternoon, I thought the computer was too slow to start, so I should turn off some services that are not frequently used, after some services are turned off, the problem described in the question occurs. If you cannot find any information on the Internet, you can solve it by yourself. Finally, I found that I disabled the Network Connections Service, I use wireless Internet access, and this service cannot be closed. Then I restart the service to solve the problem. Under www.2cto.com is the Network Connection overview Network Connection Manages objects in the Network and dial-up online data folder, you can view the local area Network and remote Connection in this data folder. Control your network connection ~ In NetworkConnectionsWindowsXP, this service is used to manage all objects in the "Network Connection" folder. By default, it is automatically enabled. If it is disabled, then, double-click the "Network Connection" icon in the control panel and the "Network Connection" window will be empty, the "Network Installation Wizard", "New Connection Wizard", and "local connection icon" are missing, you cannot view the network connection information or modify the LAN configuration. (You must restart the system to view the effect after the system is disabled "). If a user is on a LAN, he must rely on this service. You can disable this service on the client ~
