Just installed windows 7 RC yesterday and am having trouble with my wireless internet. I have a Linksys WMP54G pci adapter installed, when I try to connect to my 2wire router I just get the no internet access issue. Im trying to figure out if its my router or adapter causing problems. My 360 and other pc's can connnect with no trouble so that made me think its my wireless adapter, but I tried connecting to another wireless network next door and I get internet with no problem, so Im not sure what is causing this issue. Router or the linksys card.
