Orbi router RBR20 intermittent connectivity issues

"On my RBR20 I updated the firmware version from v2.3.5.30 to v2.5.1.16"

Before or after the problems?...a month ago...??

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

25ft maybe too close. 30 feet or more is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected. 

Any Wifi Neighbors near by? If so, how many?

Has a factory reset and setup from scratch been performed since last FW update?

Last April from Best Buy I purchased a new Orbi AC2200 - the box says RBK20W, and it includes an RBR20 router and an RBW30 satellite. It's worked mostly ok til about a month ago I started occassionally being unable to access the internet from my laptop which is connected to the RBR20 via wifi - it's gotten to the point that quite a few times a day my internet connection will cut out for about a minute or so.

 

fyi:

• 1,500 sq ft home
• My two laptops are in my office. Both my modem and router are in the bedroom across the hallway from my office, so about 25' away.
• Channels I'm using: Auto for 2.4GHz, 48 for 5GHz, and 157 for 5GHz-2.
• On my RBR20 the "Router Mode" is selected (as opposed to "AP Mode").
• I do not have any of the following enabled: Armor (security), Circle (Parental Control), nor Guest WiFi.

 

I've tried the following things, but my internet connection still keeps cutting out:

• I got a new modem from my ISP, Spectrum/Charter. (My house is only 20 years old and I've had Spectrum come out and verify the wiring in the house is good.)
• On my RBR20 I updated the firmware version from v2.3.5.30 to v2.5.1.16
• Per https://community.netgear.com/t5/Orbi/RBR20-Satellite-when-enbled-causes-intermittent-internet/m-p/1950228/highlight/true#M98508 I enabled BEAMFORMING, and per https://community.netgear.com/t5/Orbi/RBR20-Satellite-when-enbled-causes-intermittent-internet/m-p/1953580/highlight/true#M98985 I unplugged my satellite.
• On https://orbilogin.com/adv_index.htm:
  • Setup, WAN Setup, per https://community.netgear.com/t5/Orbi/Repeated-DOS-attacks-causing-dropped-connections/m-p/1851771/highlight/true I checked/enabled "Disable Port Scan and DoS Protection". (Though I'm not sure if the "DoS Attack" lines in the attached log file are the cause of my internet connection cutting out.)
  • Advanced Setup, Wireless Settings, I changed "Transmit Power Control" from 100% for both 2.4GHz & 5GHz to 50% and 75% respectively (per https://www.reddit.com/r/orbi/comments/fov5z4/connection_drops_every_30_seconds_with_orbi_rbr20/ and https://windsorwebdeveloper.com/making-netgear-orbi-great-again/).

I still had my old tp-link router in my closet, so I unhooked my RBR20 and hooked up the tp-link and the internet is working consistently. So it seems the RBR20 is the cause of my issue.

Any suggestions for how to get my Orbi to work reliably would be much appreciated. Thank you!
