ZF7343 with AppleTV3 and iPad 3 - AirPlay very unreliable
A home network is set up with a ZF7343 AP (no ZoneDirector) for wifi access (firmware version 188.8.131.52.15), and for the most part, this works extremely well - wireless performance is excellent even when many many devices are online.
However, there is an Apple TV 3 (current firmware) that we're having trouble to get AirPlay to work consistently with. There are two iPhones (4S and 5) and two iPads (2 and 3) commonly used in this house. All of them see AirPlay available only every now and then, mostly right after the iOS device or the ATV unit have been rebooted, but not always then either.
Once they do see AirPlay on their units, playback is smooth, but sometimes it just disappears.
No password for the AirPlay functionality is defined.
Neither the ATV nor the i*-devices have any general network trouble - they can access for instance Netflix with no problems.
"Packet Forward" for the WLAN being used is set to "Bridge to WAN". Since both the ATV and the iOS devices are connected through WLAN, I'm thinking the problem could be here, but that is just a guess.
Any ideas on how I could approach this?
Very thankful for any suggestions!
