The Win7 system requires a "troubleshooting" solution every time the network is connected.

  
Some optimization software or cleaning system operations may prohibit system related services and cause unnecessary problems. It is recommended that you try the restore operation:
1. Press Windows+R, enter: services.msc, open the system service, find the WLAN AutoConfig service, double-click, click “start”, and change the startup type to “auto" ;

[If the problem persists, please try this operation]
1. Click the Start menu, type: cmd in the program and file search box, click cmd, right click to run as administrator, enter: < Br>netsh winsock reset
2. After resetting the Winsock directory, please restart the computer and try again!
