IGMP Snooping

Hi, in my home network, I have a 2018 Orbi RBR50 router and have set it up with IGMP Proxying. However, I cannot find a setting for IGMP Snooping. I understand that IGMP Snooping is necessary for eff...

Hi
I stumbled across this thread and I wonder if the symptoms fit the problem, i.e. lack of multicast support?
I’ve noticed when setting IoT devices such as Nanoleaf Canvas lights, LIFX lights, Nest Cameras etc, the WLAN is serverly disrupted. All other devices seem to struggle to get to the internet. Is this what IGMP snooping would help alleviate?
During these periods where the WLAN is almost halted the internet remains connected and is appears to be ok (I have a Fing box connected to help monitoring)

RBR40 in Router mode
IGMP proxying not enabled for WAN side as issue is not there
FW: 2.2.1.210

Thanks

I was going to attach some pics showing the following but the “choose file” button isn’t working
Nest Cam timeline (darker grey indicates camera could not connect to internet)
Fing box monitoring of internet connectivity showing no issues for same period

    What is the Mfr and model# of the ISP modem the NG router is connected too?

    Turn OFF all wifi devices, then start adding devices gradually. See if you can notice when the WLAN starts to slow down or stop working correctly.

     

    What is the size of your home? Sq Ft?
    What is the distance between the router and satellite(s)? 30 feet is recommended in between them to begin with depending upon building materials.

     

    What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
    Any Wifi Neighbors near by? If so, how many?
    What WPA security modes are you using?

     

    Try enabling Beamforming

    Try disabling the following and see:
    Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Save settings and reboot the router and satellite(s).


    So far IGMP protocols don't seem to be compatible with Orbi. Espeically in managed switches.

    IGMP is used for one-to-many networking applications such as online streaming video and gaming, and I don't think that the devices you mentioned belong to this category.
