Orbi RBR10 router loses Internet connection repeatedly. Multiple re-boots needed.

My Orbi RBR 10 router with three satellites keeps losing Internet connectivity. I contacted my ISP and found that our Internet service has had no interuptions in the past two weeks. I tested the ISP by disconnecting the Orbi router and connecting my laptop directly to my ISP modem and Internet was available. My Orbi app will show Internet Offline. 

Over the past four days I have done the following to try and fix the Orbi connection issue:

Unplugged Orbi router, ISP modem, and all satellites. Plugged all back in and synced the satellites. Everything worked for a few minutes. Then Internet down again. I connected the ISP modem directly to my laptop and confirmed Internet service was indeed working. 

Factory reset Orbi and re-installed. During which time I discovered a hardware update and installed the update. Synced satellites and all worked fine for about 5 hours. I thought it was fixed with the hardware update, but then I lost Internet again. Performed another reboot of the Orbi and regained Internet for a few hours. 

Over the past 4 days I believe I have had to reboot the Orbi 10 or 12 times in order to regain Internet. Each time the app shows Internet Offline and none of our wifi connected devices will work with one strange exception. Every time we loose Internet connection it affects every laptop, tablet, smart phone and gaming device in the house. But, both of our Amazon Firestick enabled TVs connected via wifi to the Orbi will continue to stream - which makes no sense to me at all. 

My Orbi operates at both 5ghz and 2.5, but does not allow me to switch between the two options. Most of the devices are connected to the 5ghz - including the Amazon Firesticks. 

Any ideas? Thank you!
