Could try resetting network stack

(from Resetting Network Devices and Network Stack)

 

Resetting the network stack

 

Note that these commands affect all of your networking adapters, both physical and virtual, both used and unused, so you will see some errors when running these commands, where the resets targeted adapters that are not being used. These errors are perfectly normal, and not a cause for concern. Complete each step in order, even if you have done some of these previously, and even if you encounter errors.

 

 

1. In the search box on the taskbar click Start, type command prompt, right-click the command prompt result and then select Run as administrator and confirm.
2. At the command prompt (decline restarting your machine until you have entered the final command):

    

    

   1. Type ipconfig /release and press Enter.
   2. Type ipconfig /flushdns and press Enter.
   3. Type ipconfig /renew and press Enter. (This will stall for a moment.)
   4. Type netsh int ip reset and press Enter. (Don’t restart yet.)
   5. Type netsh winsock reset and press Enter.

    

3. Now restart your machine using Start > Power > Restart once more and test to see if the issue is resolved.
