Cannot connect Apple TV to new network (password error without any password request)

1. Try the Other… option instead of selecting a listed discovered network. Especially if the password has been changed.
2. Verify that the router or access point isn’t set to use WPA3, as only device models from ~2018 or later support that. Instead use WPA3+WPA2 Transitional.
3. If your Apple TV can't connect to Wi-Fi - Apple Support

Hey there, WolandLondon!

Thanks so much for using Apple Support Communities.

Being able to connect to your Wi-Fi network on your Apple TV is super important! We want to recommend that you check if your Wi-Fi network is running on a WPA3 security setup. This is a newer option so if your network is relatively new, this could be the case. In that event, this sounds like expected behavior. Not all devices will support WPA3 at this time.

You may want to speak with your network provider to see if this is something you can adjust within your network settings.

Cheers!

Thanks for the follow-up! I’m glad you got it working now.
