I know this has been posted about before, but I've read through all the old threads about this and just can't find any solution that has worked for me. Whenever a computer with windows 7 tries to connect wireless to my router it will be connected, but have no internet access, and will be detected as an "unidentified network". The only way to fix this is to restart the router. It doesn't do this if the computer is running Windows XP. I have a desktop with windows 7 connected via ethernet to the router and it works just fine. My 2 laptops with Windows 7 Ultimate are continuously having this problem though, and I hate that I have to keep restarting my router. I have tried to update the drivers to the wireless adapters, update the firmware to the router, disable the wireless adapters and then enable them again, restart the laptops, nothing seems to work. restarting the router works, and as long as they stay on the connection is just fine. But when I turn them off and go back to using them the next day, it happens all over again.
