Not being able to connect to the Internet can be frustrating. In Windows 10, this happens quite often when the WiFi does not have a valid IP configuration. In any case, this is the message displayed on the system. If you happen to encounter this problem, you are told how to reestablish the Internet connection.
Often times, connection issues have nothing to do with the ISP. Under Windows 10, several factors can explain the slowing down of the connection, or even its disappearance. When a problem arises, the first approach that comes to mind is to go through the network troubleshooter. Wifi does not have a valid IP configuration is an error message that comes up very often.
WiFi does not have a valid IP configuration: how to solve the problem?
Windows 10’s network troubleshooter often completes its diagnostics by identifying a problem without actually resolving it. When it indicates that the Wifi has no valid IP configuration, the first thing to try is a reset of the TCP / IP connection via the following Ipconfig commands which must be entered successively in the command prompt (admin):
- ipconfig / release
- ipconfig / flushdns
- ipconfig / renew
Try to connect to the WiFi network again. The yellow triangle that indicates a connection problem should be gone. If not, enter the commands listed below, still at the command prompt in administrator mode:
- netsh winsock reset
- netsh winhttp reset proxy
- netsh winhttp reset tracing
- netsh winsock reset catalog
- netsh int ipv4 reset catalog
- netsh int ipv6 reset catalog
The commands are to be executed one by one. Make sure each line is entered without syntax errors or just copy and paste each time. After all six commands have been completed, restart your computer and enjoy the Internet again.
