Two Combo Modem-Routers how to setup second as AP and/or MOCA - eviltoast

My current setup.

COAX —> Xfinity Modem-Router —> Wifi

I would like to repurpose a Netgear AC1200 Modem-Router as a range extender/MOCA/Switch to add ethernet ports to our home offices.

I know there are cheap range extenders but I prefer wired connections, and I already have the Netgear device.

Here’s what I’m thinking.

COAX —> COAX Splitter —> Xfinity Modem-Router —> Wifi

COAX Splitter —> Netgear AC1200 Modem-Router —> Wifi and Ethernet to Offices

Is this a ridiculous idea? I’m open to suggestions.

    Most consumer modem-routers speak DOCSIS, not MoCA, so you don’t want to get one. While you could probably find a ISP modem-router on eBay with MoCA, it would be more straightforward to buy standalone MoCA adapters and a WiFi Access Point.

    You would connect one MoCA adapter between a LAN port on the Xfinity modem-router and the coax splitter. Then the other MoCA adapter between the coax splitter and WiFi Access Point.

    You may want to replace the splitter with one that can pass frequencies up to 1675 MHz. A standard 1000 MHz splitter will work though speeds may be reduced.

    Finally, it’s recommended to put a MoCA filter onto the input of the splitter to keep the MoCA signal confined to your house. If your Xfinity modem-router uses DOCSIS 3.1, a 2nd MoCA filter on the modem can ensure that the modem avoids using MoCA frequencies. Not all ISPs provision DOCSIS 3.1 to use MoCA frequencies, so the 2nd filter may not be needed.
