Home sharing on; but not working
I have a Macbook Pro, an iPad3 and an AppleTV2. I have homesharing turned on, on all three devices - using the same Apple ID. My atv doesn't show any computers. I re-set the router (Netgear), re-set the atv to factory settings, rebooted all devices and still nothing. And I have the firewall turned off on my Mac (which uses OS 10.7.5). Any suggestions on what to do to get this working?
