I thought that it might have something to do with the Timed Access Control in my AirPort Extreme base station, which only lets clients onto the network that have a MAC address already in a whitelist on the AirPort Extreme. Turning that feature off on the AirPort Extreme didn't change anything in terms of allowing my Apple TV onto the network. Plus, the Apple TV's MAC address had been programmed into that whitelist all along.

I did another test, which the Apple TV failed. I turned on my iPhone's Personal Hotspot feature, but the Apple TV failed to find that network, also.

I have a Genius Bar appointment at the end of the week. Let's see, what they say, although, they are probably just going to offer to replace the unit with a refurb at a specific price.
