I've had my TV2 for about 2 or 3 weeks...always on wifi with somewhat mixed results. signal strength is always 4/5, so pretty good, but I have found a number of times that it will stop and buffer or simply stop and give a message like 'error, AppleTV is unable to ...'. I tried various fixes, including restarting the router, re-booting the computer serving the AppleTV, all to no avail. I was finally too frustrated to continue and decided to try the hard wire approach. So I disconnected the kids xbox from the ethernet and plugged it into the AppleTV. Everything worked great after that. No more buffering problems, no more errors, etc. In fact, I noticed that movies would buffer very quickly (the whole movie in a very short time). Is it the U-verse 2-wire router that is the bottleneck? I've tried changing channels, etc, but nothing gives a consistent result.
