My main pc has suddenly started to be unable to find the router which it is connected to by ethernet [cable had been changed for known good ones] it is listed as unidentified network no contact. My other pc connected to the same router has no problem. I have reset the ip address and occasionaly I can get it to connect but the next reboot kills it again. Does anyone have any idea as to what has gone wrong and how to fix it?

Don't know. Recent Windows update screwed it up?

Can you restore to before the updates or when the problem started?

reinstalled w7 but made no difference. Now fully formatting hard drive and will install w7 again and see what happens.

did you try changing the cable back, maybe one of the copper strands had broken.

still no joy tried different cables and new installation of w7 I am begining to think that the built in ethernet port has failed. I will install a network card and see what happens.
