Home sharing with iTunes 10.7, iOS 6 and A-tv 5.1.1 fixed
I have finally resolved all the issues I was having with home sharing after installing iTunes 10.7, iOS 6, and Apple TV 5.1.1. Everything with home sharing was failing; movies would never load, music would start plaing but then start buffering. None of my Apple devices were working. I have been trying to resolve this for weeks now. My solution was the 5 GHz WiFi on a Linksys E3200. I disabled the the 5 GHz and everything started working. I the went through every wireless setting but nothing worked with the 5 GHz turned on.
I hope this helps,
