2. Using netsh winsock reset the catalog and the netsh int IP reset reset. The log command

3. Update the nic driver

4. Reinstall the system

CodePudding user response:

Use network tools to sweep the first network, find other computer, to see if the IP conflict???????

Then there is the gateway and DNS also want to check,,,
