The real problem is the Airplay playback. The device loses again the connection, even in the same room with the router in a situation where the AirPort Express connected Zeppelin works without any problems, so that it can not be at the Airplay streaming itself, and also the use of iTunes Airfoil or makes no difference. This several times a day and sometimes even more than once held in a single song failures, some of which are intended to correct only by restarting the device, have moved me to send back.
