Just changed my old Win XP for a Win 7 setup. After booting up and trying to connect to the Internet for Win 7 updates, kept getting the msg 'Local Area Connection doesn't have a valid IP configuration' from the diagnostic tool in Win 7. I simply connected my Win XP router (Asus AAM 6000EV) to the Win 7 assuming it would be recognised without going through the Win 7 network setup wizard. Tried entering 192.168.1.1 in the address bar of Win 7 pc and got bounced to the diagnosic tool again. I reverted to XP machine, reconnected the router and immediately got happily back onto the internet. Also checked and successfully accessed the router via 192.168.1.1 in the address bar. Reason I reused my router is because it performed very well, despite being 6 years old and was of course already correctly configured for my ISP account. Win 7 is just another OS, so can't believe it's just because it's a wired router (most wireless routers have wired capability too anyway). Other suggestion is that Win 7 only supports 'compatible' routers - can't believe that either. Help ! Don't want to have to buy an unnecessary new router if I can avoid it. I have posted this same problem on windowsbbs forum, so if you're one and the same - sorry ! If not, I can use all the help I can get.
