FS#253 - Multicast over wireless ceases to work properly after a while on ath9k with many clients connected
User who did this - Michael Marley (mamarley)

----------
What happened for me is that originally (before netifd disabled snooping), with snooping manually disabled, multicast stopped working after a bit.  When I removed the option from the /etc/config/network file, implicitly re-enabling snooping, multicast started working properly again.  When netifd disabled snooping by default, multicast stopped working again.  I then explicitly re-enabled snooping in /etc/config/network file, which caused  multicast to start working again.

pfSense's configuration didn't have anything to do with it, as I was able to figure out using tcpdump that the multicast packets (IPv6 RAs) were leaving through the wireless interface on the WAP but never arriving on the client.  Also, I recently got fed up with pfSense and switched my main router back to LEDE (it's good to be back!).
