After a power outage, .....There is normally also a Bitdefender Box between the Orbi and the Verizon modem, that is also currently disconnected (although that doesn't appear to change the situation.) Any suggestions short of a factory reset on the Orbi router? Already been through many power off/on cycles. Thanks.
This actually sounds like three routers. Verizon->Bitdefender->Orbi. Is there more detail on that message "Orbi is providing..." such as what is incorrect about the IP address information?
Is there a computer or laptop with ethernet port available for testing?
Do any other devices connect to the Orbi WiFi correctly?

There is nothing inherently wrong about having more than one router. Thousands of customers simply hook up their new WiFi system to their ISP box and go about their business blissfully unaware that they have a "Double NAT". There are specific applications which struggle with (or cannot function with) more than one router. If the customer does not use those features, then Double NAT is not an issue. As an experiment, I set up three routers (Orbi, TP-Link, Orbi) and connected my laptop at the end. Web browsing works. Video streaming works. Email works. etc. etc. What does not work are things like OpenVPN, port forwarding to local servers, certain internet games. I use some of those features, so every device in the house is now connected to my primary Orbi which is connected to an ordinary modem (no router, no WiFi).
It seems to me that getting rid of Double-NAT is sort of like preventative hygene. Quit smoking. Lose Weight. Have teeth cleaned. etc. Having multiple routers introduces a tiny bit of inefficiency without adding any value. Removing Double-NAT avoids potential issues in the future.
