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 a...
"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.
You are correct, disabling it will force 40 MHz, enabling allows it to switch to 20 MHz in a congested wifi location.
