PC can not detect Ethernet cable
Yesterday I was playing Orion: Prelude with my friend. We were just about to play space engineers but I had to go and have Dinner. When I came back my internet was working, and then it broke. It had a red X on the Network Icon, normally this just means the the ethernet cable is playing up and when I troubleshoot it fixes it. This time I wasn't so lucky. It failed to fix the problem and it also said "Local Area Connection" does not have a valid IP address, after attempting troubleshoot a few more times it stopped recognising I was connected to a network altogether. It has not been able to recognise the network since yesterday. My Ethernet cable worked with a different PC. The Routers ports are working. And I cleaned the ports in my wall and my PC. The only thing is my PC is not connected directly to the router. It is connected to a port in the wall and then through the port to the router, as does the other PC's using Ethernet besides the one in the office that connects directly which is the one I tested the Ethernet cable with. This problem appeared out of nowhere. I have the latest drivers so if there is anything you can do to help, it would be greatly appreciated. The only thing I can do is carry my PC to the office and test it there.
Sorry for the long description but I didn't want to leave anything out,
