A:Answer I do not see it supporting MOCA in the manual. However, dont be fooled by Xfinity. There is no setup I am aware of with Comcast where you need Moca on the modem. Comcast claims you need it for the XI6 box. You do not, I have 2 XI6 with no "master" box and they work just fine, although if the internet goes out, I will need to reboot the boxes.
