CM1150V Telephony modem

I just purchased a CM1150V Telephony modem.  The Quick start gives a link to find out how to use LAN ports 2,3,4, but I cannot find the answer at this link.  My port 1 works fine connected to my router, but when I plug port 2 directly to my PC, it stays yellow and it will not connect my PC to my network using the Ethernet connection.  Anyone know how to use the other LAN ports?

    > [...] Anyone know how to use the other LAN ports?

       Someone might, but if Netgear published anything, then they hid it
    very well.

       Visit http://netgear.com/support , put in your model number, and
    look for Documentation.  Get the User Manual.  Read.  I see:

          Ethernet ports 1-4. For installation and activation, connect a
          computer to Ethernet port 1. After you install your cable modem
          and activate your Internet service, you can disconnect your
          computer and connect a router to Ethernet port 1. Your cable modem
          comes with plugs that cover Ethernet ports 2, 3 and 4.  For more
          information about Ethernet ports 2, 3, and 4, visit
          netgear.com/support/product/CM1150V.
          [http://www.netgear.com/support/product/CM1150V]

       I'd've thought that "plugs that cover Ethernet ports 2, 3 and 4"
    would be a hint.  I'd also guess that you'd need a NAT router if you
    wanted to connect multiple devices to any ISP connection which provides
    a single public IP address.

       Same here.  Typical Netgear documentation.

    apparently the other ports are only for aggragation and cannot be used as a hub.

      The modem needs a external wired router put behind it. Then you can connect all the rest of the devices to the router. ALL CM series modems are modems only. C series modems are modems with built in router and wifi features for future reference.
