Hi. My appologies if this is a repeat thread, but I could not find a solution to this problem. From browsing this and other forums in seams there are quite a few complaints similar tio this one. The problem is.... My network adapter needs to be disabled and re-enabled regularly. It is not periodic (eg. somtimes i have to do this every few minuets, sometimes every few hours. What happens is that everything works normaly, then randomly everything stops, and after a min or so an error appears in the 'Networking and Sharing Centre' as shown in attatchment... It works fine everytime I boot, but then when I start using it CAN stop working. I'm using Windows 7 build 7100 with an NVidia Networking Adapter. When I check, it retains its IP Address, but won't ping it. I have also disabled IPv6 in an attempt to stop the problem with no success. It is absolutly infuriating. I am seriously considering reverting back to Vista, which I upgraded from as I NEVER had a problem with that. Any help anyone could provide will be extremely helpful. Many thanks, and sorry about the awful spelling.
