i went from an iphone 3gs running ios5 to a 4s running ios5 on the day it was released. for the life of the 3gs airplay was flawless. now with the 4s, airplay runs for between 30 seconds and 30 minutes, but inevitably and without fail, it will stop playing and will kill my entire house wi-fi signal for up to 5 minutes. i have a time capsule and an airport express, and both have the most up to date firmware.
there are no new wireless devices of any kind in my house that could be to blame.
i spent about 80 minutes on the phone with apple support today. at first they wanted to blame it on blue tooth interference, but i told them that i have never even turned on blue tooth on any of my devices.
so, the only thing they could suggest was changing the channels on the wi-fi.
unfortunately, i was not able to get the signal to "die" with i was on the phone with support, so as far as they could tell changing the channel solved the problem.
5 minutes after i got off the phone with them, the problem came back and killed the entire house wi-fi.
this is not acceptable. i am afraid that this will not be addressed.
