RBR50 and 3 RBS50: streaming issues during Zoom calls when connected to satellites, requests lagging

Thank you very much for prompt reply.

1) I'm not quite sure about the distance - eqipment is on different floors, but it should be ok, since everything was working fine for couple of years until recently and I haven't moved sats or router.

2) channels. I'm already using channel 6 for 2.4Ghz and 48 for 5Ghz. I changed it from Auto because I used to have issues with Ring cams. 

No Wifi neighboors except for wireless printer and guest wireless network from Orbi

3) never did factory reset since last update.

4) Never tried: Beamforming and MIMO (tried this when addressing Ring issues), Armor, Circle, Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz 

I will try steps under No4 and will let you know

Thanks again!
