Thank you all for your responses! To provide a little more detail on our current set-up, we have cable coming into our main house connected to the Cox Panoramic modem/router (not the Gigablast, the previous one). We have an out-building in the back yard that also has cable coming into it for TV. It is set-up as a single account, and the out-building has access to the DVR that is physically connected in the main house; i.e. any shows recorded on the DVR can be viewed in either house. So in that sense, the two buildings share the same basic cable connection.
For Internet access, Cox installed the Actiontec WCB6200Q02 extender in the out-building which is connected to the coax wired inside the out-building. My understanding is that the extender communicates with the primary modem in our main house via MoCA to provide Internet.
I'd like to install the latest Gigablast modem, but I don't want to lose Internet for the out-building. My best-case hope was that I could simply replace the old modem with the new one and everything would work as it does now, but it sounds like that may not be the case.
So, I'm looking for suggestions on how to make this work. I could just stay with the current modem, but I imagine I'll have to "upgrade" eventually anyway.
