No issue with internet dropping when connecting devices straight to modem via ethernet. Devices connected to orbi router via ethernet lose internet as well.

Yes
The outlined restart process has been done multiple times.
Has a factory reset and setup from scratch been performed since last FW update?
Yes

What is the distance between the router and satellite(s)?
About 70 ft to downstairs unit. Second satellite has an ethernet backhaul.

No. This is something I always disable.

What mode is your ISP modem working in? Router or Modem only?
Your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT
https://kb.netgear.com/30187/How-to-fix-issues-with-Double-NAT
Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop
Try #2 first...

Modem is in modem only mode. Router has been switched to bridge since I recieved it. I always use my own routers so this has always been the setting.
No issue or concern for double NAT
Wireless radios are also always disabled.
