Win 10 Surface Pro 3 not connected to internet when wire is plugged in

I am having this issue with a Surface Pro 3 on a dock, that when it is plugged in to a certain port it doesn't recognize the internet connection. If I take the surface to a different port and plug it in it works, if I get a different surface and plug it in to the port I am working with it works. Its only when the surface I am working with is plugged into that specific port, that it doesn't work. I need this surface plugged into this port, I can't plug it in anywhere else.

I have tried updating drivers, changing the dock, and also plugging in a USB to Ethernet adapter to bypass the dock. Nothing has worked. I also can't just get a different Surface because I don't have another surface with Win 10 on it. I need to have this Surface connected to this port but it will not work.

Any Ideas?
