Belkin RT3200/Linksys E8450 WiFi AX discussion

I used to watch IPTV just fine on my home network with a rt3200 via igmpproxy on an older snapshot. However, since updating to the 22.03.0 version, it's totally broken:

  1. If I disable igmp snooping, WiFi gets flooded with multicast traffic as expected when someone is watching TV, and slows down to an absolute crawl.
  2. If I enable igmp snooping, multicast traffic is not working at all and I am unable to watch TV.

On a previous snapshot, igmp snooping was working just fine to prevent multicast flooding on WiFi, but multicast worked just fine and I was able to watch IPTV. Is someone experiencing the same issue?
