I am having difficulty connecting to my airport extreme wireless router. I have been able to get online intermittently but every time the computer goes to sleep it kicks me off. Some time I can't get on at all. I have updated the the wireless driver (the device is working properly), I have uninstalled Norton, I have tried so many things in vista I have forgotten them all. I have two friends who have the same computer as I do, try to configure my system, no luck. However, I can still get online with my macs. Does anybody have a solution...???
