I have to say, that my orbi 753 is now running stable again with 4.6.3.7 after a complete reset to factory defaults.

Erased RBR750 using the "Revert to Factory Default Settings" from the Backup settings in the Advanced Tab

At this point i recommend to disable the AX feature via the Admin tab going to Wireles Setup under the Setup Item then uncheck "Enable AX - This WiFi mode will enable AX features" for both 2.4 and 5 GHz. I did this as a last step in this process as i was still seeing the same connection issues after this full reset.

I did not do a Restore of the settings, did everything from scratch.

Then I performed a reset on my 3 sattelites using a paperclip until the orange flashing light.

Added the sattelites one by one, this was a bit of a struggle but succeeded in the end.

At this point i actually disabled the AX features because the system was still unstable, i recommend doing it earlier as described above.

After disabling the AX Features the system is stable ever since (4-5 days)

 

A factory reset that i tried earlier by just using the paperclip on the RBR750 did not resolve anything, also doing that did not fully erase the RBR because the custom sattelite names were remembered and all the custom names for the connected devices were remembered.

So really do an Erase using the Revert to Factory defaults from the backup settings.

 

I did not find any performance issues having the AX features disabled, but my line is just 600mbit, and this is still what i get on most of the devices that are able to handle that speed (iPhones/iPads. Laptops)

 

I am now in a situation where I am very affraid to touch the system again, even stayed away from rebooting it. So a confirmation, root cause and solution from NG is very desirable of course!

I can also confirm that the WIFI is more stable with the AX features completely disabled via the Admin menu. I am occasionally getting satellite "disconnects" due to the blue LED turning on. I wonder if the wireless backhaul uses the WIFI 6 connection when WIFI AX is disabled. I use the wireless backhaul to connect my Wireless Backhaul -> Satellite -> Ethernet To -> Nvidia Shield -> 4k TV. Either way, I really hope NG fixes this and adds an option to disable updates for a period of time at least. I still have not been contacted by NG support but hopefully they are working on it. Still very frustrating.

My settings are the following:

• Disable AX for both 2.4 Ghz & 5 Ghz
• Tx Power at 50% for both 2.4 Ghz & 5 Ghz
• CTS/RTS set to 2347 for both 2.4 Ghz & 5 Ghz
• Enabled 20/40 MHz Coexistence
• Enable WMM (Wi-Fi multimedia) settings (2.4GHz b/g/n/ax) for both 2.4 Ghz & 5 Ghz
• Preamble Mode set to Automatic for 2.4 Ghz & 5 Ghz
• UPnP is disabled
• DHCP is enabled on the router but DNS is being directed to another service (AdguardHome) with second DNS populated as backup (1.1.1.1)
• Orbi RBR750 is in router mode
• Satellite and router are approx < 30 ft from each other. Router is on first floor on side of the house and the satellite is on the second floor opposite end. House is ~2100 sq feet.

Glad you both found some stability on your systems. Seems like disabling AX mode is key in all this. I'll pass this on to NG for review. 

Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
