Make sure your on release 4.0.206.0 or greater. There was a bad bug that was fixed in 4.0.206.0 that had significant packet loss on the wireless network if Multicast was enabled.
We don't have multicast enabled. We do have Peer to Peer blocking disabled (so we are enabling Peer to Peer). It wasn't a conscious decision, just the default setting on the box, and we haven't changed it. My only recommendation is try to limit the bandwidth allowed for Multicast.

By default on the controllers under General System configuration options, Ethernet Multicast Support is disabled by default, and we chose to enable Peer to Peer Blocking Mode. We are being asked a by a researcher to change both of these settings to allow both multicast and peer to peer connections in the WLAN, and our first reaction is to grimace and gnash teeth a bit. Am wondering if anyone is actually allowing multicast on a large WLAN and seeing any problems, added load, or general observations worth noting? Same with peer to peer. Regards to the group- Lee H.
