I need some help in a major way here is my situation, I have a tibook 800 1 gig ram running os 10.2.8 and an airport extreme base station with the latest software and everything has been pretty much great for the last six months until now. It all began yesterday, I started loosing my signal every few minutes. I have always had a pretty good signal at least 75% of the status bar, but now it goes to about half way down then nothing even when I'm in direct line of sight with the basestation from only about 10 feet away. This is really frustrating. When it goes down to no signal it comes back within one minute. I have tried resetting the basestation and setting up a new network and that didn't help, I also unplugged it for a while thinking maybe I left it on too long (6 months except for a power outage). Has this hapened to anyone else please help.
