RBK852 is giving me high latency/delays during video conference (coming from Google Wi-Fi)

Your Arris SB6141 Cable Modem  is not only a bit dated, but has the Intel PUMA 5 Broadband Modem Chipset.

 

Although I haven't used Google Meetings, but Zoom and Skype and they have been perfect. Also your testing being through a browser introduces "overhead" that doesn't help in accurate readings.

 

From what it sounds like you have "Some Traffic", Obstructions and are kinda pushing things to an extreme with the "100' wire" and trying to stretch things out. I use nothing less than Cat7 anymore and try to keep things within a logical range.

 

I would recommend trying this, along with what FURRYe38 has posted, and see what happens:

• Advanced > Setup > Wireless: Turn on the AX Settings. And maybe turn them off to see what that does.
• Advanced > Advanced > Wireless Settings: Turn Off "Coexistence"; Leave WMM on; Change RTS/CTS to 2347 (or try 2346) for both 2.4 & 5.
• And for the time being treating VoIP and VCs like "Needy Spoiled Brats" that appeasing would be much easier than ignoring.

Thanks for all the info and suggestions!

• I didn't know about the problems with the SB6141... I've been meaning to upgrade it, but my bandwidth hasn't "needed" me to yet.  Maybe you gave me just the excuse to do so anyway 😉
• Regarding the testing in the browser (and probably goes for the old modem too)... the thing is, all other factors being the same, when I use the Orbi, I'm getting strange round-trip/latency issues - when I go back to Google Wi-Fi, they are gone. That's the frustrating part. As I mentioned in my original post, everything else seems fantastic (3x speed improvements, 2-3x better ping, better coverage, etc)... I would have expected VC latency to have improved as well. ( I'm literally just taking the ethernet cables out from Google Wi-Fi and putting them into Orbi - and vice versa - well, and also making sure to power off the system I'm not using).
• ❓Question: I'm assuming that it's fine to connect the first LAN port from Orbi to my bigger switch, correct?
• Also I probably exaggerated the length of those ethernet runs. Looking at the diagram, there are ethernet cables going up the inner walls of the rooms on the right side and make their way across the room to then go down to the "network area" in the garage (where the router is). Anything plugged into ethernet is totally performing fine for my needs 😉
• What I didn't include in my OP was the experimentation I did with Coexistence, WMM, RTS/CTS. Things I actually did try changing (all independently):
  • Turned Coexistence Off
  • Turned off WMM for the 2.4GHz band (I didn't need some of my IP Cameras to get priority)
  • Tried 32, 512, 2347 for RTS/CTS
  • I tested after each (meaning, I looked at the graph) - nothing really changed.  For some of the tests, I noticed the graph wasn't as "smooth", but there was still a consistent wave of latency.

Still, I'm going to try various amounts of futzing and see what happens.
