CAX80 will not factory reset
Honestly don't know what to do with this thing. I have had other issues with it in the past (dhcp assignments would constantly drop connections so I had to statically assign like everything in my home), but this new development is a new one on me. I moved recently and swapped from Xfinity cable to AT&T fiber. Was trying to get my CAX80 connected to the AT&T modem/router and use it instead of theirs, so naturally I wanted to factory reset this thing. New environment, new ISP, seemed reasonable. Every time it would factory default, load up, and allow me into the admin page though, it would only remain default for a minute or more. Then I would get kicked out while it rebooted again, and come back online with it's old configuration again. I have tried doing it via admin page, AND via the reset button on the back of the device. I tried for hours and every time it would somehow get it's old config back on there and not work properly. I have no clue what to do with it anymore and had to shelve it and use the ISP router. Any ideas? It's on the latest FW and other than the dhcp thing, has served me well at my old home.
As mentioned, if your trying to use the CAX80 as a router only connected to another router, this won't work and is not supported. The CAX80 can only work as a gateway router or in modem only mode connected to a cable coax ISP service line.

the CAX80 is connected via Cat6 cable on an ethernet port on the ATT router gateway. Turn on IP passthrough in the ATT RG and you can use your own (in this case the CAX80) router as the home router instead of theirs. That's the ultimate goal, but I would like to erase my old config from the CAX80 to start fresh on it since it is a new ISP.
I understand there is a cable modem component to the CAX80 and I'm not trying to hook that up in any way.

The CAX80 is not compatible with Fiber services. Fiber use ONTs as interfacing with home networking routers. The CAX80 is for cable ISP services.

If the CAX doesn't detect a connection on the coax port, it automatically reboots. So it won't work as a router only device
