Video call jitters / latency
My config Cable modem Router RBR750 / 4.6.14.3 2x Satellites, both RBS750 / 4.6.9.11 Cat5 backhaul WMM enabled for both bands CTS/RTS 64 for both bands Distance of iMac from satellite — 7m Co...
I recommend a power OFF of the Orbi system and ISP modem for 1 minute then back ON with the modem first then Orbi system. Test for the video call problems.
If problems persist, factory reset and setup from scratch. A complete pull of the power adapters for a period of time after the factory reset then walk thru the setup wizard and setup from scratch with a wired PC and web browser. https://kb.netgear.com/22697/How-do-I-install-my-NETGEAR-router-using-the-router-web-interface
Recommend setting the default DHCP IP address pool range to the following after applying and a factory reset: 192.168.#.100 to 192.168.#.200.

I would power OFF the ISP modem for 1 minute. Factory reset the Orbi router and power it off. Power ON the ISP modem and let it sync. Then power ON the Orbi router and walk thru the setup wizard again using a wired PC and a web browser.
Press the back reset button for 15 seconds then release.

I've been using this version for a while and have not seen any video issues in Zoom meetings I have had nor phone calls. I asked some others to test with and without SIP ALG enabled and saw now issues here either.
You may want to check your devices and PCs for issues.
Thanks FURRYe38.
I may have time on Wednesday to give this a go.
I can respond I think to the alternative you raise: "You may want to check your devices and PCs for issues."
With a wired connection to either satellite, all video calls from any device work a treat and Waveform gives an A grade. It's only wireless that has the problem, and I think it's very much more likely that the corresponding problem lies in one product — the Orbi — than all the others separately.
Thanks again and I'll be back here as soon as I can.
Bufferbloat testing is mostly for ethernet connections. Due to wireless having many variables and factors, would not give good or accurate test results for wireless connections.
I hadn't come to that conclusion FURRYe38. From my reading, networking entails buffering at layer 2 of the OSI model. Wi-Fi LANs operate at layers 1 (physical) and 2 (data link) of the OSI model, with layer 3 (network) running 'on top'.
A quick web search turned up these links that seem to confirm my take on this, although I am most definitely not an internetworking expert 😆https://www.usenix.org/conference/atc17/technical-sessions/presentation/hoilan-jorgesen

Hello psheld ,
I understand that you are experiencing call jitters with your Orbi. These issues can be caused by one of the features within your router. Please disable SIG ALG then test your video conferences for continuous jitters.
Please follow the steps below for instructions on how to disable SIP ALG on your Orbi router:
- Orbilogin.com
- ADVANCED
- WAN Setup
- Select the "Disable SIG ALG check box"
Best,
Kevin
