I have 2 black paper weights right now! Sure I can pull up Netflix all day, I never loss Internet connection , but as for home share my computer is a ghost to both ATV in my house. Unless I unplug them and plug them back in, letting them reboot then and only then don they show back up, and even then I will loss it again depending on what I'm doing it will last for 10 ,15, even 56 minutes and 25 seconds one time. I called Apple and let me just add then need to get someone to answer there tech support that knows what there talking about, trying to tell me it's a issue with ATV when it goes to sleep well , that would be great excuse if I didn't already have the sleep mode turned off
So that didn't work and I have tried all the suggestions on this discussion topic still nothing. So then I talked to a Apple Rep today in a store, he tells me apple is aware of the issue and to expect a software update on ATV and iTunes to fix it. My fingers are crossed that I don't have two 200.00 paper weights to throw away.
