Orbi dropping internet connection

Furrye38, thank you for your response.  Here are my replies.  I will try running after making your suggestions and report again when I have results.

To clarify, the problem is dropping the WiFi connection, not the Internet connection, as wired connections remain connected and with service.  When a drop-out occurs, I can't tell if the device was connected to the router or the satellite.

What FW is currently loaded? V2.1.4.16
What is the Mfr and model# of the IP modem the Orbi is connected too? Arris TM1602
What is the Mfr and model# of the ethernet switch if one is in the configuration. There is no switch in the configuration.  Wired connections are made to the base and satellite.

What is the size of your home? Sq Ft? 2,100 ft sq.
What is the distance between the router and satellite(s)? 30 feet is recommended in between them to begin with depending upon building materials. >40 ft line of sight, with wood and plasterboard framed walls in between.

What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz. I've run both Auto and manual selections based on monitoring all local traffic, with the same drop-out occurences.
Any Wifi Neighbors near by? If so, how many? Several WiFi access points can be detected, but all with significantly weaker signals than mine, as reported by Netgear's WiFi Analytics app.

Try disabling the following and see:
MIMO, Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Save settings and reboot the router and satellite(s).  MIMO, Fast Roaming, and IPv6 were never enabled.  I disabled Daisy Chaining (since there's only one satellite, the feature should be ineffective anyway) and rebooted both router and satellite.

Has a factory reset been performed on the system and set up from scratch after the FW was updated?  No.  Has this been known to reduce or avoid drop-outs?
