Question Recently swapped from cable to fiber. We bought our own router for the cable 2 years ago. No WAN input on current router. MOCA or their router?

So,
We've had a Nighthawk c7800 for cable for the past 2ish years or so.
Recently we moved, and we got Fiber hooked up. The fiber goes into the house and into a hub that distributes it to whatever we have.
Problem is, there's no WAN ethernet input for the C7800, just a coax. So we gotta use their modem/router... (I don't see a coax to coax on their hub either)

Question is: Should we use a MOCA adapter and hook their ethernet to our coax and keep our c7800 since it was expensive and we don't wanna toss it (we could save it for the future I guess)? Or are we better off just using their router?

Is a MOCA adapter good/worth it? Or should I buy a new router that's different with an ethernet input? Or just swap all of our stuff to their modem/router?

What is the purpose of the moca. Are you using moca to extend the network in your house over the coax.

If your goal is to somehow connect the wan coax on a cable modem then moca won't work. Cable modems use Docsis which is a different protocol that MoCA and run on different frequencies which is why they co exist.

The only use I can see for the c7800 is to use it as a AP if you need wifi in a remote room. Since it does not have ap mode as a option you need to disable the DHCP server. Set a IP that does not conflict with your new router, cable a LAN port to a LAN port on the new ISP router.

Depending on the details of how the fiber comes into the house it might be impossible to replace the ISP router. It all depends on if the ISP router wan port is fiber or ethernet. If it is fiber it is almost impossible to get a compatible device and even if you find one they tend to not allow it. From previous posts on this forum the only exception seems to be in India the ISP there allow consumer owned routers that have fiber GPON interfaces.
