I've had this problem now for a week or two and it's gradually getting worse. I'm on Windows 7 and have a wireless network set up. The adaptor and router are both Belkin (G).
I've done all the suggested solutions in Windows, disabling IPV6, changing power settings etc but nothing has worked for me. I've also tried a new network adaptor which unfortunately had the same problem.
After trying everything suggested, I'm leaning towards this being a router issue. I first did a reset (switching off power to the router and back on) and it worked fine for the rest of that day. The next day, it began to drop connection again. I've played with a few settings and the only thing that made any difference was changing the wireless channel. Again, this work for a while but still didn't fix the issue.
My question is, does this sound like it could be a router issue?
