I've tried to do exactly that, but the 7111's seem to hang after transmitting just a few GB of video. I have the network topology somewhat backwards as I have a media server (IPTV source) attached to a 7111, which is connecting to a 7982 which serves the entire house (co-located with cable internet connection and NAT router).
Is there any known fix for the 7111 hanging all the time? I've tried two different units and they both do exactly the same thing. It seems that the wireless interface just stops responding, as you can still ping the Ethernet interface and connect to web management via LAN, but nothing at all via wifi.
The log on the 7111 shows nothing, and the same story on the 7982 (not even a disassociate).
I'd love to get this sorted out, as there doesn't seem to be a replacement (even from a competitor) for the 7111.
