I have an Apple TV connected wirelessly to my LAN via the wireless facility in the UC520.
The Apple TV can get onto the iTunes store with no problem, and has received a valid address from the DHCP server.
One of the features of the Apple TV is the ability to browse the iTunes library of and stream from other computers on the LAN.
Unfortunately the Apple TV is unable to browse other computers on the LAN for some reason.
When I do a cold start on the Apple TV I can see it on the network and it can see the iTunes library on other computers. But after about 2 minutes the connection to the other machine is broken and it drops off the iTunes library. However the Apple TV is still connected to the LAN and the internet.
The Apple TV uses multi-casting packets across the LAN, and I have seen reports that this could be the cause of the problem.
Could I have suggestions please as to how to diagnose this problem, or even better maybe someone has already fixed this problem?
