Apple TV and iOS7?

My ATV 2 is saying that it is not connected to the internet. This problem seems to have coincided with downloading iOS7. I don't know why they should be related, so maybe it's just a coincidence. Nothing I have tried has helped.

Wifi is working fine.

Internet is working fine.

Computer is working fine - well connected to the internet.

Restarted the Airport.

Restarted the computer.

Restarted iTunes.

Restarted the ZTV - about ten times.

Nothing.

I know my user name and password are correct even though it sometimes says they aren't.

I see on these threads that there are a lot of problems with ATV right now. Just don't know if they're iOS7 related. And, no I don't think I should have to unhook the ATV and connect it to the computer because that isn't what I bought it for. I'll take the whole mess to the Apple store and make it their problem. (Sorry to be snarky but access to netflix and itunes is a big part of my evening entertainment.)
