I have had my Orbi RBR20 up and running with no problems for over a year via ATT DSL (we live in the "country" and have few internet choices). A week ago, I switched over to Ubifi (a cellular interne...

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? Built in router here by chance? If so, 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

Thank you FURRYe38 for responding.
The modem is a MOFI4500-4gxeLTE with a built in router. I have the modem configured to Passthrough/bridge mode with the wifi disabled and my Orbi in router mode. That worked for a few days, but now I can't connect back up. I can try the other option (disconnecting the wifi radio on the modem) though that may be beyond my skillset. I'll let you know how that goes, I appreciate the response

So, I disabled all the wifi antennas in my modem and enabled the bridge passthrough and was still unable to set up via app. As before, I get to the page were the app says I have no internet connection. I tried again by connecting the Orbi via ethernet to the modem and an ethernet to my pc ( a mac) and attempted the set up via web browser. I was able to set up, wifi running via Orbi (bridge set up via modem and all modem wifi off) and things worked fine for about 15 minutes then the Orbi disconnected from my internet again. I enabled the wifi function on my modem and it is working fine. Could the issue be my Orbi has crapped out? I am confused by the fact it had been working for days, then lost connectivity. Thanks for any help!

I should have said that I disconnected the wifi radios, not antennas
