Hoping to add MoCA adapter to Coax Fios setup

Hi there,

I have an old Fios package with ONT connected to router via coaxial cable going through multiple floors. I want to add a MoCA adapter to a separate room, and I was hoping someone could verify this setup would work. Please see below image of my current setup and my proposed addition.

Link to setup

Will I just be able to add the MoCA adapter in Room 2 and connect to that via Ethernet to my PC?

Thank you in advance

This should work, yes. The coax signal is broken down into a number of channels based on the frequency range. Some channels are for cable TV, some for external Internet connections, and some for internal Ethernet connections. Looking at the back of the G1100, there are LAN and WAN LEDs next to the coax port. The WAN light is lit if your Internet connection from the ONT is over coax. That light should be lit for your setup. That is how the G1100 firewall uses only a single coax cable. It filters traffic coming in from the ONT over the WAN frequencies. Traffic that passes the firewall rules is then forwarded to internal devices using the LAN frequencies. (If your connection from the ONT were over Ethernet, there would be an Ethernet cable in the Ethernet WAN port, and the WAN light next to the coax port would be off.)

Inside your home, devices like the set-top box (STB) connect to the G1100 via coax using the LAN frequencies. They ignore the WAN frequencies on the coax. A MoCA adapter like this Screenbeam MoCA 2.0 adapter also listens to the LAN frequencies (by default, but some can be reprogrammed to listen to the WAN frequencies instead). The G1100 will put traffic destined for your remote PC on the coax LAN frequencies. The MoCA adapter would get that traffic and it to Ethernet traffic for your PC.
