I have two iPad 2's, a 2011 Airport Extreme, and an AppleTV 2 (1080p version) all updated to latest firmware. They all connect to the same wifi network just fine. When I go to mirror either iPad to the AppleTV, it will try, then immediately switch back to the iPad. If I turn off the iPad wifi and then back on, it works fine. Just a pain. I using WPA2 Personal and I have the 5ghz option enabled on the Airport. Any ideas?
