Only need router for Gigablast and not modem?

I do not have Voice.  I had bought (erroneously in my eagerness) a Netgear AX6000 Wii Cable/Modem Router which I was told will not be compatible.  If this is true, I'll have to sell that hardware and buy the modem and router as separate devices?  Aint technology wonderfully confusing even to someone who has been using it since the mid 80's? 😃

I appreciate all the help I can get.

Is this your device:  www.cox.com/.../netgear-cax80.html

I didn't find many posts for the Netgear AX6000 in the Forum, which is good because subscribers aren't having problems using it..

This subscriber uses it on the Cox network:

But is the AX6000 sufficient for my needs of a new install, as there's not even a cable outlet in the room.  The only one in the house is a coax outlet to Cox's Panoramic Wifi in a room on the other side of the house. 

I think I don't understand your "new install."  Cox is already providing service to your house?  There's already an active Panoramic modem/router connected in another room connected to a coax outlet?

Cox will provide service to 1 billing address.  I guess Cox could connect another service and combine the services onto 1 bill.

What do you want to do?  Do you want to connect your AX6000 to the Panoramic?
