New router (Linksys e4200) installed, new AppleTV (2). Everything works but mirroring Ipad2 to TV. Could share laptop (stream movies from pc with itunes) and AppleTV worked fine. However, when attempting to activate Airplay to mirror Ipad2, all wifi connections drop (even to unrelated laptops). Found references to channel conflicts with neighbors, and changed router to use unique channels (must change to 'manual' config in router wireless settings), but did not help.
