Nighthawk -- Lights are all on, but nobody home

I have a Netgear Nighthawk R7000. This past week, I found that I could no longer connect to either the 2.4GHz or 5GHz WiFi. This has happened periodically over the past year or so, and, typically, ...

Your ISP modem already has a built in router and wifi. This would be a double NAT 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 NG 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 NG router gets from the modem. https://kb.netgear.com/25891/DMZ-on-NETGEAR-routers

3. Or disable all wifi radios on the modem and connect the NG router to the modem, LAN to LAN configure AP mode on the NG router.

I would try option #2 first with the NH router.

You might disconnect the router from the ISP modem and factory reset the router with one wired PC connected to the router. See if you can get the setup wizard to appear in a web browser at 192.168.1.1

Thanks for all of the additional info.

Only reason I'd kept the router in place after moving to T-Mobile, really, was there are only 2 Ethernet ports in the gateway, and I need 3. (That, and the router has Circle built in which I pay for and use.)

BUT.... If the router isn't playing nice with the new gateway, perhaps a simpler move would be to get an Ethernet hub? Correct?
