Shulou(Shulou.com)06/01 Report--

Recently, after installing the original Win7 system and patching the driver of the network card, everything is normal after setting a fixed IP address for the computer, but after the computer is rebooted, it is found that it cannot be connected to the network. There is an exclamation point in the network icon in the lower right corner. Open the network and sharing center-- > Local connection-- > details-- > find that the address of IPv4 is the same as the IP address obtained by ipconfig / all. All are shown as: auto-configure IPv4 address: 169.254.123.188 (preferred)

But there is no problem looking at the local connection-- > property to see the fixed IP address that was previously set.

So I thought that the computer should have enabled the automatic configuration IPv4 function, resulting in the fixed IP cannot be assigned to the computer.

Try to turn off the automatic configuration IPv4 feature with the command:

Run cmd.exe as an administrator

Enter: netsh winsock reset catalog enter

Enter: netsh int ip reset reset.log enter

Restart the computer and find that the set fixed IP address is normal in the local connection-> details, and then execute the ipconfig / all command to find out.

IPv4 is also consistent, open the browser and find that you can surf the Internet.
