So we've moved upstairs, new network and everything. We have 1 computer that when we turned on it said there was no connection plugged in. This is odd however as the Light on the switch for the right socket is flashing and the lights on the back of the computer are flashing. We tried the same socket and cable in a different computer and it worked so it's not an issue with the socket, cable or switch. Tried a new cable and socket and it still isn't detecting it.
We've had this problem before and restarting a few times seems to solve it usually but it isn't this time. I'm out of ideas so I now need help. Only other thing I can think of is reinstalling the network drivers.
Any help is appreciated.
