    Cox cable and routers/switches.

    I have an Arris TN602G cable modem supplied to my by my digital cable
    company (Cox).

    I have the following devices, which all support access to the Internet.:

    Dell PC running Windows XP Professional w/SP3
    iMac with OS X 10.5.6
    Apple Time Capsule
    Wii
    Sony PlayStation3
    Sony XBR9 TV

    My house is wired with Cat6 cable which all works perfectly.

    When I have either my Netgear GS105 switch or Netgear FM114P router
    connected to my cable modem and routing signal through the Cat6 to my house,
    then IF the cable modem is connected to the switch/router NONE of my devices
    can see each other.

    If I do not have the cable modem connected to the switch/router then ALL of
    the devices CAN see each other.

    I have rest my cable modem and the router (but obviously not the switch).

    I have switched everything off and started by switching everything on,
    working from the wall outwards (cable modem - switch - computers) and I
    still get the same result.

    The only answer I get from my cable company is that I need to speak to:
    Microsoft (for Windows support); Apple (for OS X support); Netgear (for the
    switch/router support); Sony (for the PlayStation3/ TV support); and
    Nintendo (for the Wii) support.

    Can this be anything other than a problem with the Cable company? It's
    late, I'm tired, this problem has been going on for over 4 months and I'm
    sure that I have missed out some of the many, many things that I have
    tried/done.

    Make a note of the IP address and Default gateway of each of your
    networked devices (PC's, game systems, etc) with the cable modem
    disconnected (every device can see the other devices), and then
    compare those addresses/gateways with what you see when the cable
    modem is connected (devices cannot see each other). I think you'll
    find that your devices have public IP's versus private IP's, and if
    so, it's a good bet that you've connected your router to the cable
    modem improperly. Be sure the router's WAN port is connected to the
    cable modem. You might have connected one of the router's LAN ports to
    the modem by mistake.
