I've been hearing about airport problems around macrumors but never bothered to read any of the threads because I never had them.... until now. I have a SR MBP. 3 weeks ago I switched ISPs, and everything worked fine at first. I had WEP encryption set up for my network. About 4 days later, the connection stops working, even though it says airport is connected. I couldn't figure it out, so I went in and turned of my network encryption. Worked instantly. Then, a few days later, same thing. So I TURN ON encryption... it works. A few days later, same thing... turn OFF encryption, and it works. what the hell is going on here, what is this cycle of alternating security???? could it be the router that's the problem? i went from cable to DSL and now I have an integrated DSL modem/router box. its kind of a piece of *****, but i have a PC laptop that doesn't seem to have the issue (although I don't use it too often).
