If this still happens after you update the firmware, then it would be good to know

1. Whether you are connecting to work-related zoom conferences, or whether these are personal.  Some companies host their own Zoom servers, and it would be good to know if that is a possibility here.
2. Your ISP and internet connection type (fiber, cable, satellite,mobile broadband).  Some ISPs will dynamically adjust your upload and download speeds, and that could also explain what you are seeing.

Before updating:

Same happens with Traffic Meter disabled? 

Disable IPv6 on the RBR and test Zoom? 

Enable SIP ALG and test? 

 

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? 
Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.

 

Does this happen with the RBS turned OFF? 
Does this happen with both wireless and wired devices connected to the RBR?

I followed all the suggested setting changes including:

 

Disable Guest network

Wireless Settings: 2.4Ghz Channel to 01

Wireless Settings: 5Ghz Channel to 48

Disable SIP ALG on (set to open)

Advance Wireless Settings: enable WMM (2.4Ghz) 2347 (Short Preample/50%)

Advance Wireless Settings: enable WMM (5.0Ghz) 2347 (Short Preample/100%)

IPV6 - Get Automatically from ISP ( I can't see how to turn off other that use a DNS Server)

IP Adddress Assignemtn - Auto Config

Traffic Meter is enabled with traffic volume contro by no limit

 

My internet speed seems fine 109 Mbps download /40Mbps upload - backhaul status reports as good 

I'm using a Mac for Zoom which is wireless connnected to the RBR850 router, and have tried both wirelessly connecting and wired connected to the satellite.

The same lag and still the warning exists. 

 

The firmware i old V4.6.9.11, so that is next up.

 Just wondered if you or anyone else had resolved or have a recommended firmware version that work without disrupting all else?

 

There is newer firmware:

As an observation, people seem less interested in diagnosing problems with older firmware versions.
