Unable to connect to DHCP after using VPN

I used a VPN to play a game I was having some issues with.

After uninstalling the VPN I have had some issues connecting to the inteet & my local network on a Etheet connection, wireless works fine.

I have Googled extensively to no avail.

What I have noticed is that when running ipconfig, no default gateway is set & the IP address looks private.

When trying to run ipconfig /release & ipconfig /renew I get this error:

An error occurred while renewing interface Etheet : unable to contact your DHCP server. Request time out.

Any ideas what could be happening here? Or what I can do just to vanilla my network?
