Hi,
It’s most likely multicast based discovery (like Bonjour, mDNS), make sure that when client connects to another AP, both client and TV reside still on the same subnet (I don’t see much details on this in pastebin and frankly speaking I still have to improve my XIQ AP cfg reading skills, I’m used to WiNG much more). If this is ok, you can check underlying switch port. If it’s the same port, it shouldn’t be a problem. If it’s a different port and client/server are on different APs, take a look at any security/storm control related settings that might prevent multicast traffic from passing thru between switch ports. If all is good here, I’d try to look around if there is a different default behavior regarding BUM traffic handling on these AP models, call GTAC eventually.
Hope that helps,
Tomasz
