If you have ever installed Hyper-V, you may have noticed left over vEthernet adapters. You may also noticed that you have issues with TCP/IP. Here’s what to do.
Open a command prompt or PowerShell as an Administrator
Type netcfg -d
This will uninstall all of your adapters (including hidden) and reinstall just the physical adapters. Make sure you have drivers available – just in case.
You may want to also reset TCP/IP settings.
netsh winsock reset
netsh int ip reset
netsh interface ipv4 reset
netsh interface ipv6 reset
netsh interface tcp reset
netsh int reset all
netsh interface tcp set global autotuninglevel=disabled
netsh advfirewall reset
