Q: AppleTV tries to connect to internet radio while playing music from my Ipad via AirPlay

As the title says..

When I play music from my Ipad mini via AirPlay, the sound drops every ten to fifteen seconds.

On the TV-screen it shows the info about the band, song etc, but when it drops I get a box with "internet radio" written inside, before the sound comes back, and everything is normal again. Very annoying to have the sound cutting like that multiple times during a song..

AppleTV (gen 3) is wireless connected to a Airport Extreme, and with HDMI-cable to a surround reciever.

The Ipad and AppleTV have the lates updates (IOS 8.0).

Tries with a 4S with the IOS 7.1.2 version, but it's the same story with that..
