I have been using Windows 7 on a new hard drive for around 2 months now on my PC and have had no problem with connecting to the internet. I am using a netgear DGN2000 ADSL2 + modem router and like i say i have had no problem with the internet then suddenly i would be on the internet then connection would be lost. The diagnostics would say "A network cable is not properly plugged in or maybe broken" The number of the port on the router goes off and i have to restart the router to get the connection back then it may work for 1/2 an hour or 1 hour then the same thing happens again. I have no problem using the wireless connection on my laptop. I also have a hard drive with vista on and there is no problem with the internet connection there, so the router and cable are fine so it must be a winows 7 issue. As to why it has only just started doing it maybe it was an update that has caused it. Please help as its doing my head in. Thanks.
