I have an Apple TV and love the AirPlay feature but it has not worked since I replaced my netgear router with a WD N750 router. I read online that disabling WMM QoS may solve the problem.
I logged into my router settings, went into advanced mode, clicked on the wireless tab, and found a switch to turn WMM QoS on and off for both the 2.5 and the 5 ghz networks. Unfortunately the switch is not highlighted and I cannot change it from on to off. Does anyone know how to turn it off? Any other suggestions for fixing AirPlay?
