We have about 20 Apple TV's and 200+ iPads on our network, for some reason the TV's will just drop a user, they cannot mirror video or audio. There is no rhyme nor reason to it. I came into, with zero traffic in the building, and it wouldnt mirror. i rebooted the ATV, and reset the Ipad network settings and it finally worked. This is not an acceptable work around for my staff.. These are all wifi'd through AP's with an IPV4 network. any ideas would be greatly appreciated.
