What is the Mfr and model# of the ISP modem the NG router is connected too?
What is the size of your home? Sq Ft?
What is the distance between the router and satellite(s)? 30 feet is recommended in between them to begin with depending upon building materials.
What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?

I'm in the same boat, I have random wifi drops and slow performnace with my Orbi RBR50 (with two satellites). I run the Orbi in AP mode since I already have a firewall and router. In fact, I have a farily extensive home network with an assortment of systems and IoT devices. Everything is fine without the Orbi, whether I pull out my Netgear Nighthawk or my old Cisco AP. The Orbi is great after a power-cycle, but performance slowly degrades over time until it becomes almost unsuable from *any* device connected to the wifi -- MacBook Pro, assorted iPhones or android tablets or even simple embedded devcies that are only sending a small HTTP request every 15 seconds.
The Orbi of course shows solid connections to both satellites.
And I have tried all of the suggestions from this forum post and others, all to no avail (changing 2.4GHz channels, disabling assorted settings, etc). It also affects all devcies using the Orib, whether 2.4 or 5 GHz. And it isn't anything as simple as a saturated network connection, the uplink at the moment is runnign at only 100Kb at the moment, while my iPhone can't even downlaod a simple web page on the WiFi. The only thing that is consistent is that it works after a reboot and degrades over time.
I even took a walk around the house with a couple of Android wifi scanning apps and signal strengh is great everywhere.
If only this thing supported syslog (or any other sort of logging) I could get it to log to my server and see if there were any errors or other intersting messages.
My Setup (DSL -> pfSense firewall -> Cisco 3750 -> RBR50)

To add some more data, I pointed my smokeping install at my Ring Doorbell (on the WiFi at 5 GHz). You can see how poor the reponse gets with ping responses as high as 11 sec at some times. When it isn't bad the average is closer to 10 ms. The pair of 2 GHz devices I pointed smokeping at show similar trends, although not as bad with the normal average being around 5 ms and the peaks at 1.5 sec.

I also tried turning off one of the satellites Thu afternoon, as far as I can tell it made virtually no difference.

Please post this to a new post. Your test maybe results of a different environment and configuration from the OP here.
Make a new post and lets see if we can help you out some.

netgear RBR50 - 2500 Square feet, two satelites - one is 15 feet away with direct line of sight, second is also 25 feet away - but on second floor. Main computer is hard wired to router and when the wifi goes down there is still internet connection through PC. There are neighboors nearby with WIFI but this is a stand alone residence - no one within 100 feet.
During last outage - I checked error log - which displayed the following: "Critical (3) - no ranging response received - T3 time out"
I have set 2.4 Ghz channel to 1, 5GHZ channel is set at 48
Disabled MU-MIMO
Disabled IPv6

Replaced router - new router CBR40 - same issue
system went out again - new error message: MIMO Event MIMO: Stored MIMO= -1 post cfgfile MIMO = -1
please help - this is beyond frustrating and entering into intolearable.

The distance between the base router and satellites are too close. 30 feet is recommended in between them to begin with depending upon building materials. I have mine at 40 feet in between. Wood and dry wall contstruction.

Have removed the satellite which was 15 feet away. Did not fix the issue
re-istalled the original RBR50 - and now service is worse.
Still have connectivity through hard wired PC throughrouter - but wireless is inconsistent and dropping.
work and family are seriously being disrupted right now. this log and reply every 24 hours is not solving the problem - please escalate to next tier or level.
