Recently, my Windows 10 system has been unable to obtain an IP address effectively (whether wired or wireless), but I can surf the Internet normally after setting the IP manually, so I suspect that a service is not started.
I checked Baidu and found that it is true. Now the solution is recorded as follows:
1. Open system services. In the service interface, make sure that the two services [wired auto config] and [WLan autoconfig] are running normally. If they are not running, first change the "Startup Type" to "Automatic", and click [Apply] - [Start] - [OK] That's it.
2. Right-click on the Start menu and click "Network Connections" in the pop-up menu;
3. Right-click Ethernet, select "Disable", and then re-enable it;
4. Right-click on the Start menu and click "Command Prompt (Admin)" in the pop-up menu;
5. Enter: netsh winsock reset in the command prompt box and press the Enter key, it will prompt: Successfully reset the Winsock directory. (An organization window may pop up if antivirus software is installed on the computer, we can choose to allow the operation)
6. After restarting, the problem can generally be solved!
