Since the recent Airport Utility update and associated Airport Express and Time Capsule firmware update, my Apple TV does not speak to my mac mini been told to check they are on the same wifi network. Don't know why, because up until the update, the two were very happy together. And they are too far away to link with ethernet cable. My Apple TV (AT2) is upto date. Weird thing is that when I play music from my mac mini to speakers attached to the Aiport Express it works fine. So clearly the wifi system is working. Seems to me, the Apple TV now can't see my library. Anyone else experiencing similar issues?
