RBR850 Multicast Stutter

Question

Hi,&nbsp;While trying to play any multicast content, it stutters and lags.&nbsp;I think it might be due to a missing IGMP Snooping protocol.Orbi is in Router mode and connected via ether to the satellites.Next some managed switches are connected to these satellites, which in turn have the multicast traffic connected via ethernet to it. IGMP Proxying is enabled (not disabled).Any suggestions to tackle this in the current setup or any news on an IGMP Snooping option?&nbsp;Thanks in advance!

IGMP appears in the user manual only in the context of IGMP Proxy, to allow devices on the LAN to receive multicast from the internet.

Are there any Ethernet switches in the network?
Some switches are known to have defective IGMP Snooping (cannot remember which, sorry)

Hi,&nbsp;Yeah one Netgear nighthawk, however it shouldn't be the issue because if I plug it directly in the satellites, the issue remains. Do you know what snooping is supposed to do and if it could help?

What is the brand and model# of the switch your using? Managed or non managed. If managed, then any IGMP protocols should be disabled if any RBS are ethernet connected to this switch.&nbsp;

IGMP Snooping is a feature to reduce the amount of multicast traffic by learning which devices on the network participate (and which do not):
https://en.wikipedia.org/wiki/IGMP_snooping&nbsp;
&nbsp;
If the feature is not working correctly, then the switch might device, "these multicast packets do not need to go out these particular switch ports because there are no devices out that port that are part of this multicast group."
&nbsp;
My sense is that a failure of IGMP Snooping would mean that a device simply cannot connect to a multicast host.
That would be a different problem that playback "stuttering".
