My airport extreme was acting up (loading pages reaaaaaaaaaly slow compared to just plugging in ethernet) so today I set it all up again. It worked great for a couple hours, then the speed dropped to below that of a phone modem. The Macrumors frontpage took about a minute and a half to finish. My applecare is up, so if I call Apple and it turns out I'm messing something up... it'll cost me 50 bucks. Has this happened to anybody else, is this fixable or is it a hardware issue with the APX?
