Nighthawk® Multi-Gig Speed Cable Modem for XFINITY® Voice (CM1150V) MoCA?

A simple question, but I can't find an answer.  Does this modem support MoCA?   If not, if I set up MoCA adapters, will it work?  I understand that MoCA 2.5 and DOCSIS 3.1 may have problems with ov...

    No it doesn't. 

    If you're adding moca adapters they need to be setup off the router. 

    so CM1150v-----router-----moca adapters

    Could you explain why the moca needs to connect to the router?  In particular, my plan was a wireless AP connected to one of the modem's RJ45 posts, one for moca, and one to a switch.  The fourth could be a spare or directly connected to a desktop.

    With no router, should I connect the moca to the switch instead?

    Thanks.

      Sure. The CM1150v is basically a modem without a router. your isp assigns 1 public ip address to your account through the modem. That is whats provided to the router which then assigns private ip addresses to the devices on the network.
      You can go modem-----moca-----moca----router since in effect its passing that 1 address to the router. But if you're trying to attach multiple devices without a router, only 1 device will get an ip address.

      The extra ethernet ports on the CM1150v aren't well educated to the public for them. Both on netgear and the ISP's side.
      For the average consumer, they're worthless. Some can use port 1-2 for wan port aggregation. The rest can only be used if the isp supplies multiple public IP addresses which the majority of isp's don't do.

        Thanks.  Based on this, I will need a "router", not a "switch", to connect to the modem?

        And all my devices will need to connect to the router:

          modem -> router1 -> wireless AP

                                     2 -> moca

                                     3 -> other (switch, computer, printer, etc, dependent on number of ports on the router.)

                                     etc.

        The plan was to have a wireless AP connected using PoE, to a switch providing PoE, so I could easily run a line to a central location in the house for the wireless (modem is in the east end of the house).  The above would have to modify a bit:

          modem -> router1 -> PoE switch -> wireless AP

                           router2 and etc. as above.

        Any thoughts on what the "router" should be?

        Thanks again.
