RBR50 out of nowhere is losing connectivity 5-7 random times a day
So, I am relatively technical and out of nowhere by Orbi Mesh has lost its mind. Spent two weeks with Spectrum to make sure everything is perfect between the Node and my House and then with Spect...

Ok, when I tried to switch to 11 on 2.4 - I received this error when trying to apply, then I got the Please wait a moment....forever and finally logged out.
When I logged back in 11 was saved....although I THOUGHT I new a few things, not sure what that means in the real world performance, seems like a huge drop...but
Per Wi-Fi Alliance guidelines for 40 Mhz and 20 Mhz coexistence, even if you select "Up to 400Mbps" mode, your product’s service rate might drop to 20 Mhz. This typically corresponds to 192 Mbps performance.

That is just saying that 20/40 Mhz coexistence can result in the system choosing to use 20 Mhz in order to avoid interfering with other wifi.
Do you get many 2.4 ghz client connections? Are they connections where performance matters (laptops, phone, tablets)? Or are they iOT devices (smart power switches, etc)?

As for 2.4 - quite a few, say 20 out of 40, mostly all IOT Devices - Blink Cameras, Thermostats, Smart Lights, etc.

Generally those devices don't need a lot of bandwidth. Even the cameras only require 2 mbps (and only when they are streaming). So I wouldn't worry about the warning - which is just saying what might happen if you leave coexistence on.
Plus your problem is about dropped connections. 20 mhz provides longer range and more stability than 40, so leaving 20/40 mhz enabled is probably the best option. Then the Orbi can decide what channel width is best, given the competing wifi it sees.
