I have a similar situation.  I have a 4k TV, but I have a Netgear C7800 Modem/Router (Xfinity compatible)

I want to switch from my Tivo box to an Xfinity box.

However, Xfinity support won't send me a 4k box as they say it won't work with my modem.  

I also have a MOCA box, if that matters.

Is there any way I can get an Xfinity 4k box that will work with my modem?

Thanks for any help someone can provide.

I have two coax wired XG1v4 DVRs that work with my Netgear router and an Xfinity modem in bridge mode.  The other 4K box is the Xi6 wireless model that does require the user of Xfinity internet gear. 

I tried Xfinity and they said they couldn't supply a XG1v4

Perhaps because my modem is netgear they balked at sending it. 

Sorry, not familiar with MoCA.  It's possible that using MoCA and a non Xfinity modem over Xfinity TV coax is a fly in the ointment.
