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.
