Really can't explain it except that my 3rd gen had the same issues. With it wired I would have degraded streaming issues but wireless on 5ghz it performs better. I think the issue is that like the 3rd gen if I looked at my switch at random times within a few minutes or less I will see the LED light go off and on again like it was reconnecting. I though it was the switch but it does this with every switch I tried and even plugged right in to the router. Also waking up the 4th gen Apple TV it would say network connection lost and then after a few seconds reconnect but on wireless it is connected right away when I wake up.
