Windows 10 Run the Network troubleshooter followed by networking commands

https://support.microsoft.com/en-us/h...

The Network troubleshooter can help diagnose and fix common connection problems. Using this troubleshooter, then running some networking commands afterwards if needed, can help get you connected.

To run the Network troubleshooter

In the search box on the taskbar, type Network troubleshooter, and then select Identify and repair network problems from the list of results.

Follow the steps in the troubleshooter and see if that fixes the problem.

If that doesn’t fix your connection problem, try these things:

1. Reset the TCP/IP stack
2. Release the IP address
3. Renew the IP address
4. Flush and reset the DNS client resolver cache

To run these networking commands in a command prompt window

In the search box on the taskbar, type Command prompt, press and hold or right-click Command prompt, and then select Run as administrator - Yes.
At the command prompt, run the following commands in the listed order, and then check to see if that fixes your connection problem:

1. Type: netsh winsock reset and press Enter and reboot your computer.
2. Type: netsh int ip reset and press Enter and reboot your computer.
3. Type: ipconfig /release and press Enter.
4: Type: ipconfig /renew and press Enter.
5. Type ipconfig /flushdns and press Enter.

Good Luck.
