I am in the same boat as you. I know my cable line is live, I have a Comcast splitter going to the MoCa device which the tech guy said I needed. I set it up as I have read several placess to do and it is still not working.
Does the second router have to be compatible with Xfinity in order for this to work?
Does it matter if I use a MoCa splitter?
