Orbi AX4200 WiFi 6 Router (RBR750) Random Reboots
Solved my issue with my Orbi AX4000 (RBR750) rebooting randomly or loosing wifi connectivity especially on the guest network and want to share what fixed it for me. Reboots occurred every few days and as frequent as 2-3x a day.
Uncheck option - Enable 20/40 MHz Coexistence for 2.4 GHz band
I have another router managing all my network traffic. The Orbi is in AP mode. I live in a wifi saturated location and have a reasonable amount of wireless devices connected to the Orbi. The wifi saturation is probably causing the router to reboot to look for a clear channel. I have another wifi AP running strictly 5 GHz. Neither the main router nor the other AP has disconnection issues.

That is strange! It should be the other way around, as I understand it! 🙂 The setting "Enable 20/40 MHz Coexistence for 2.4 GHz band" says that if the quality of the connection is bad, then you accept to go down to 20 MHz bandwidth. When this is disabled, it means that you only accept 40 MHz, so either 40 MHz or nothing, which will make the connection vulnerable to band satuaration.
"The 20/40 MHz coexistence setting permits the 2.4 GHz radio to use the entire 40 MHz bandwidth (and interact with both 20 MHz and 40 MHz bandwidth clients) unless it finds another AP using an adjacent channel on the 2.4 GHz band, in which case interference is unavoidable."
The option enables 40 MHz which then chokes out from high saturation. Even devices connected to the NIC ports lose internet connection. With this option disabled, the router strictly uses 20 MHz. It's slower but does not have wireless interference.

No, it's the other way around: Disabled means strictly 40 MHz bandwidth! If you have any legacy devices, then you need to keep 20/40Mhz enabled so these older devices can connect to the wifi. If you don't, then you can enable 40Mhz only on 2.4Ghz. You don't have to always use 20/40Mhz channel width.
- Does it matter if you raised the DNS pool to 100-200?
What is the size of your home? Sq Ft?
What is the distance between the router and 📡 satellite(s)? 30 feet or more is recommended in between RBR and RBS📡 to begin with depending upon building materials when wirelessly connected.
Also try turning down the power output of the RBRs wifi radios from 100% to 50% and see if this changes anything. Under Advanced Tab/Advanced Settings/Wireless Settings would help for wifi congested areas.The wireless router to satellites are about ~43 feet apart with power settings at 50%. My other wireless AP is about the same distance at different locations on 5 GHz, 80 MHz, so there is no overlapping. Even with lower power settings, it does not negate my neighbors' broadcast strength and configurations for interference. The AP's are hardwired to the main router. Something to consider, is trying 25% power with the option for 20/40 MHz enabled, but I don't think it would work as I can see 7 other wireless routers from my home.
So you have two wifi systems running at the same time?
What FW version do you have loaded on the Orbi system?
What channels are you using one each system?
