Recently I've been having major problems with my Airport (PowerBook G4) -- a lot of stalls and stops when opening even the most basic webpages, can't download new software (although I did manage to download the latest airport update) -- it's almost as if I'm on dial-up. It's always run a bit slow, but lately it's just been unacceptable. I'm pretty sure it has nothing to do with my provider. Does anyone here have any idea why this is happening?
