I know this is a problem that lots of people have had and I am at my wits end trying to solve it. Every day I turn on the ATV's I get the "Cannot connect to XXXX Library, please check, etc.". Every time I have to go to my computer, turn off itunes, and then turn it back on again. We have multiple ATV's in the house (2nd and 3rd Gen). All are hard wired to our Airport Extreme router, via an ethernet switch and all set to home share with my Imac. I have tried all of the following suggestions that according to other threads has worked for other folks: 1) Updating all software on all ATV's. 2) Assigning static IP's for all devices including my main computer with the itunes library on it. 3) Setting my main computer with my itunes library on it to not sleep. 4) Setting all my ATV's to not sleep 5) Resetting all ATV's to factory resets and then setting up again. 6) Turning of IPV6 7) Turning Home share off and then on again by entering password on all devices and computers. I'm about ready to throw each and every one of them away and try a Roku or something. Anyone who has ANY other suggestions would be most appreciated. I used to have this problem on one or the other ATV every once in a while. But now it is every single day.
