RBR40 Blinking White Light
At about 3pm today I started experiencing connection issues on some devices, so AI decided to reboot the RBR40. It will not reconnect to my Verizon modem . It remains in a pulsating white light. ...

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

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.

The firmware release should not cause this problem. There should be no harm in updating the firmware, but I am not confident that would solve whatever has gone wrong.
If you want to update the firmware, download the router and satellite files from the Netgear support site to the laptop
https://kb.netgear.com/000070458/
- Extract the *.img files from the router and satellite download.
- Connect the laptop web browser to each satellite using the satellite IP address.
- Use the Firmware Update menu item to update firmware on all satellites.
- Finally, connect to the router and manually update the router firmware.
It would be a good idea to make sure you have a backup of the configuration before starting any updates.
Also would not hurt to make two checks:
- Does the cable between router and modem appear solidly connected?
- If you connect to the router web interface using the laptop what does it show about the WAN connection?
