I've got Win 7 RC1 installed on my 15" UMBP through Boot Camp. When I first started using it everything was fine, everything worked great. After a while though, my Wifi connection dropped. Only way to get it restarted was to re-input the password. Waking from sleep a while later same thing happened, had to re-in the password. (I don't know that that was the problem, but it seemed to get it going.) Then it started connecting to the Wifi, but only with "Limited Access", no internet. Moved the machine to another room, closer to the router, seemed to work better, but yesterday afternoon, quit working altogether, doesn't even see the network. I've downloaded and installed the latest Broadcom Drivers for Windows, didn't seem to do any good. Anyone have any ideas?
