Frage: 5GHz network does not work on Apple TV after recent update
I have an Apple TV 4 64 GB. Unfortunately the device is not able to connect to my 5 GHz WiFi network since the recent system update to TV OS 11.2.1. The 5 GHz network is displayed in the network list but as soon as I try to connect, the password is rejected and it does not connect. I definitely used the right password and I tried it for several times - without success. Any idea? This is really annoying as here in the city center the 2,4 GHz network is not useable due to about 20 concurring WiFi networks.
Apple TV, iOS 11.2.1
