RBS850 satellites lose internet and gateway connectivity several times per day
I have been a satisfied Orbi AX customer since March (RBR850 + 3 RBS850 satellites, satellites are 30-40 feet away or on a different floor from each other). My Comcast modem is in bridge mode and the RBR850 handles routing. I also have my old RBR50 system (+ 3 RBS850 satellites) running off of one of the RBS850s for device compatibility for some old IoT devices and also an old Asus router hanging off of one of the RBR850 for guest network. Both the old RBS50 and the old Asus router are running in router mode so Double NAT for these (but they work fine). The problem I'm having is with my primary Orbi AX system where one satellite loses internet and gateway connectivity 2 or 3 times each day.
While the AX system is hardly set-and-forget and trouble-free, I've had it working well for my primary wireless needs and there were no performance or disconnect issues. About 2 weeks ago one of my RBS850 satellites would lose Internet connectivity each day. I had not changed the firmware or anything else that I recall. The symptom is that nearby wifi devices or the IoT home devices wired to that particular satellite would lose internet connectivity. I know exactly when it happens because (only) the nearby always-on Nest cameras would email out an alert. As soon as I unplug that satellite, everything connects to a different satellite or the base and internet connectivity is immediately restored.
I thought it might be a hardware issue with that particular satellite, so I swapped it out with one of my other RBS850s. The same day, the other satellite lost internet connectivity in the same way (so I put things back and concluded it's not a RBS850 hardware issue). I've tried leaving that particular satellite powered off, but then later that same day another of my RBS850s (in a different part of the house) lost internet connectivity and its nearby Nest cameras began complaining. I now have 2 of my RBS850s powered off to see what happens.
When the problem occurs (lost internet connectivity) I do have admin browser connectivity to the problematic satellite (192.168.1.193) but cannot ping the RBR850 (192.168.1.1). I can list the satellite's connected devices but don't see any IP conflicts or anything strange. If I switch my laptop to one of my compatibility wireless network, I can connect to the RBR850 admin website (192.168.1.1) and it shows the problemmatic satellite as connected and also lists its connected devices. I checked and there are no apparent IP conflicts for any of my ~50 devices.
My AX base and satellites are now all running the latest firmware (V3.2.15.32). They were running 3.2.15.25 when the problem first appeared a couple weeks ago and updating to the latest hotfix firmware hasn't helped. I tried doing a full reset of the base and every satellite, then restored the base config via a backup made last month, but the issue still occurs. I disconnected all of the wired devices to that one satellite, did not help. I also tried restarting all the wireless devices that apparently connect to that one satellite. I've tried turning off AX mode and also setting preamble from Auto to either Short or Long. None of these have fixed the issue so right now two of my RBS850 satellites are powered off (the third needs to stay on as an ethernet bridge to my work laptop). I just did this yesterday and don't know yet if my third RBS850 will start exhibiting the same issue now.
I'm at a loss of what to try to stop my periodic Orbi AX internet disconnects. I hate to have to put my old RBR50 system back in as the router and just use the RBR850 system in access point mode. Any other suggestions of what to try?

Does the problem still appear if you turn OFF the ASUS and other RBS50s and just run the 850 system alone?
Has a factory reset and setup from scratch been performed since applying v32?
I have not see any issues with mine on v32. Two RBS850s wired to RBR.

Yes, the problem occurs with just the 850 system alone. I've done some testing today, trying different modifications. I will also try doing a factory reset and setup from scratch this weekend to see if that helps.
The problem appeared today within a few hours (devices connected to the one RBS850 satellite lose connectivity with the internet and RBR850) after trying each of these changes independently:
- Disconnected both the Asus and RBR50 from the RBR850
- Turned off the DMZ setting on the RBR850 to the RBR50's IP address
- Unchecked Disable IGMP Proxying on the RBR850
- Checked Disable SIP ALG on the RBR850
Sounds like something going on with your system. Something to contact NG support about.
Might turn OFF the RBS and test just the RBR alone to see if the problem maybe central to the RBR.
I updated to v32 on my system and has been solid since going on while over a week ago. I have done 1 reboot since while testing for a problem I was having with a NEST controller and app. Swapping RBS around seem to have solved it though I haven't been able to reproduce that problem again. I think 1 RBS was in a bad state which may have caused the problem. Otherwise system has been up and running well. I'n using default settings instead of changing to CTS 2347. Leavng 20/40Mhz enabled instead of disabled. Only thing I have changed is manual channel 11 and 48.
