WIFI Turning on and off several times a day

[aallred]

I have had my Orbi for several years and it has worked great.  However, the last month or so, it won't stay connected.  It probably disconnects at least 20 times a day.  I am constantly reconnecting to wifi during the day.  I have checked with my internet provider and I have a great signal, I have unplugged the power for 30 sec and then plugged it back in.  Any suggestions?

What happens when the wifi goes down?

What firmware version do you have on the device?

A number is more useful than "the latest". (It may not be by the time people read this.)

What is the distance between the router and satellite(s)? 30 feet is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected. https://kb.netgear.com/000036466/How-far-should-I-place-my-Orbi-satellite-from-my-Orbi-router

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?

Try enabling Beamforming and MIMO(MIMO may or maynot be needed) and WMM. Under Advanced Tab/Advanced Settings/Wireless Settings

Try disabling the following and see:
Armor, Circle, Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Save settings and reboot the router and satellite(s).

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

When the Wifi goes down, we just lose service to all devices.  I am using firmware V2.3.5.30.

Can you give some feed back to some of the questions presented?

Sadly "it doesn't work" answers won't get us much further. The devil is in the detail.

What happens to the LEDs on the Orbi router?

Do you have any wired devices connected? If so, what happens to them when the wifi dies?

Have you ever done a "factory reset" on the Orbi?

If it is connected to a modem, does that have any lights that could help us out?

Come to think of it, what is the make and model of that modem, if there is one?

Then there are those questions and suggestions from @FURRYe38. They are based on past experience of things that can go wrong.
