    My apologies if this is an old question, I couldn't find a satisfactory
    answer on either these discussion groups or through an web search.

    I have a home network with 3 sub nets. The reason I have 3 subnets is
    because each subnet is wired with wireless routers making the link between
    the wired networks. I'd prefer to keep it that way and not have to drill a
    hole through the floors... The routers are one NetGear WGR614v6 (with
    netgear's firmware as it does not support flashing) and two Linksys WRT54G
    flashed to tomato firmware. The NetGear is connected to a comcast modem which
    is the WAN access. It is configured as a regular access point, with a DHCP
    server for subnet 192.168.1.x (mask Both Linksys are
    configured as clients - 192.168.2.x and 3.x, mask -. Both
    linksys routers have their firewalls disabled (netgear's router is enabled).
    Both linksys routers have a static IP reserved for them on the netgear. The
    netgear has also static routes configured to redirect traffic for the
    subnetworks to their matching routers. The linksys routers have static routes
    configured to redirect traffic for the other subnet back to the netgear

    I am able to ping and tracert from a machine in one subnetwork to another

    For instance from my windows 7 laptop ip i can trace to my
    windows xp desktop to which a USB printer to share is connected:

    tracert -d -4

    Tracing route to over a maximum of 30 hops

    1 1 ms 1 ms 1 ms
    2 1 ms 1 ms 1 ms
    3 4 ms 75 ms 2 ms
    4 2 ms 8 ms 2 ms is the IP in the 1.x subnet of the linksys router.

    However if I try to open \\ in windows explorer I get a useless
    "unknown error" after a while. Network troubleshooter also fails to find
    what's wrong. Similarly if I try to add a network printer, my win 7 laptop
    won't see it, even if I type its full address - \\\HPDeskjet

    Windows XP's firewall is configured to allow folders and printers to be
    shared with other computers on the network.

    What am I missing so sharing isn't working?

  2. Hi
    Make sure that you have one computer with two Network cards and Windows
    version that can do Bridging (like Win XP Pro).
    Then bridge the two subnets and you would get one cohesive Network with
    seamless sharing and printing.

    Cannot connect to Network Printer across 2 subnets

    I have a similar question related to sharig network printers across subnets... can anyone help e?

    Here's the setup done by the old another IT guy that left:

    -- Office Location A --
    PC A1:
    ip addr:
    can print, yes; physically connected to printer via USB

    PC A2:
    ip addr:
    can print: yes

    ip addr:

    -- Office Location B --
    PC B1:
    ip addr:
    can print: NO (it used to work 5 days ago, and now it cannot even find the printer on the network)

    The old IT person setup a network between Office Location A and Location B, and I have not changed anything to the network since I came on board.

    How can I get the PC B1 at Office Location B to see the Network Printer that is located at Office Location A?
