Instant On - Wireless

Hello, I'm, rather new to using Arubas.  I have a dealership that was using old Arubas that never needed to be touched.  I replaced them with 505s recently and this broke a local instant messaging system they were using.  The IM seems to use multicasting and I was wondering if the Arubas filter this.  When I was on the old Arubas to note the settings that I could mirror in the new ones, I didn't see much - probably due to my inexperience.  I can see more options on the 505s, but I'm not finding anything on multicast.   Unfortunately I don't have the old Arubas anymore to dive back in to find what I may have missed.  Any advice would be highly appreciated!

The Airheads community might be a better place for your question, because your APs are not Instant On. But you could try this:

Configuration -> Networks -> choose your SSID -> Show advanced options (on the bottom) -> in the Broadcast/Multicast section, set the option "Broadcast filtering" to disabled.

Might be worth a shot.

My apologies, I wasn't sure where to place this because of my inexperience with these devices.  However I was able to find the multicast option behind an "advanced options" button that avoided my gaze and now everything is working just fine.
