Orbi 5Ghz Network

Your Modem already has built in router and wifi. IS the modem fully bridged and wifi disabled? This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-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

After making sure of the ISP Modem configuration, I would do a reset on the RBR and set it up from scratch. You can turn OFF the RBS while you do this, just set the same SSID name and PW and later on turn on the RBS and it should reconnect. 

Any progress on this?

Has a factory reset and setup from scratch been performed since last FW update? Nope, was hoping to omit doing reset.
