i had no problems for the first couple of months using my ATV with my iphone 4s. over the past week, i haven't been able to do so. i don't have the play on atv option with music and i can't dbl click on the home button and scroll over to find the mirroring option anymore. i reset the modem and router once and that fixed it temporarily but i don't want to have to do that every time. my atv is hard wired to the router and is online. can watch hulu, netflix, home sharing, etc. same with my iphone. any idea why this is happening?
