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.

So apparently, after 3 or so hours I started to get some connectivity back. I tried to update to latest firmware during this time, but the Orbi app AND website said I had the latest Firmware. Strange. My RBR40 and my RBS20s remain in the same firmware version. The Verizon modem is the G1100. As of right now, there are no issues.
I did check the Verizon router directly and I had Internet access.
I have had the same setup for 7+ years, I found out that I had a double NAT situation going on, so I changed the Orbi to AP mode and basically lost all setting options.
I am not sure what happened here or if it is a song of things to come. Any thoughts here...

Yes. I found out about my double NAT. I removed all wifi options on my Verizon FIOS G1100 Modem/Router and set my Orbi RBR40 into AP mode.
Is there a better option (e.g., performance or function benefit) from way or another. For example, would it be better to set Verizon modem to bridge mode and have Orbi manage my network?
I have been seeing different views on this (e.g., not being able to properly or fully set modems to bridge mode). Setting Orbi to AP mode really takes away a lot of the functions of Orbi (which may be available on the Verizon modem itself).

If you have their set top boxes, then you'll need to keep their router in router mode.
I use FIOS as well, and have chosen to double-route. IMO the disadvantages are overstated. You just need to be careful about port forwarding.

I had it this way for 7+ years...both Verizon and Orbi as the router. It was never an issue. I stepped away from port forwarding or any single device having a priority.
Now my Guest SSID can see everyone on the network (which is now checked on by default in Orbi). I had this unchecked when it was in router mode. I am not sure if there is any advantage or disadvantage for the checkbox, but I always like more control and options.

This is a good configuration.
Ya if you have additional services from the ISP, you'll need to keep there router in router mode. But ya, keep the wifi disabled there and use the RBR system in AP mode for better wifi and coverage for the home. You'll be fine with this configuration. AP mode doesn't have lots of configurations. But your ISP router should cover the router needs when needed.
Maybe later on, upgrade the Orbi system to a newer generation system.
Good Luck.

Yes. I use Verizon for several cable boxes as well as for land phone. I will check the Verizon modem configuration for anything I may want to use (e.g., UPnP). I have been thinking about the next Netgear mesh network - whether that be Orbi WiFi 7 or the nighthawk. My goal is to have more/better coverage around the yard. I also am not sure if Verizon put out a router that handles more than 1 gb (maybe 10?), which would definitely require me to upgrade if I switch Verizon routers.
