I am having issues with disconnection during playback. All of a sudden I get a playback error. If I try to resume what I was watching it will resume 1 out or every 10 times. the other 90% of the time I get an AFP error and I have to restart the apple tv.
I am having the exact same issue with SMB shares from my Netgear 3800. Worked flawlessly until recently. Thought it might be network issues due to a powerline adapter being in the mix but I rejiggered things and am having the same issue over wireless and direct wired to the 3800. I also tried a 3400 I have in the house and am getting the same problem.
