Zoom is continously displaying low bandwidth and screen sharing lags

I've been trying to solve a similar issue on RBR850 with three RBS850. running Zoom. Zoom is continously displaying low bandwidth and screen sharing lags (although it get there in the end)

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?

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

      I'd also start by updating the firmware.

       

      Does the problem happen only on wifi?  Or is this also an issue with ethernet?
