    I access the internet via Comcast and a Motorola cable modem connected
    to my desktop via a network cable (i.e., not USB). That works fine.

    I have a wireless connection between my desktop and my Dell notebook
    via a D-Link DWL-G122 802.11g Wireless USB Adapter. The notebook has
    built-in wireless networking. I can exchange files, etc., between the
    desktop and the notebook, so that works fine too.

    However, I haven't figured out how to access the internet from my
    notebook.

    Any ideas?

    TIA

    It's called Internet Connection Sharing. Have you tried to implement it
    on the comouters O/S?

    Yes, ICS is enabled on the desktop, but thanks for the suggestion (I
    double-checked). I'm including more info in case it's helpful:

    ---

    DESKTOP:

    Has built-in lan connection on motherboard (i.e., no separate NIC
    card); connected to cable modem via cable to that lan connection
    (i.e., not using USB for it).

    Network connections:
    1 - a 1394 connection, disabled so it doesn't complicate things
    2 - the lan connection to the cable modem; obtains IP address
    automatically; ICS is turned on
    3 - the wireless connection; IP address set to 192.168.0.11, subnet
    set to 255.255.255.0, uses Windows to configure wireless settings

    The DESKTOP can access the internet w/no problem.

    NOTEBOOK:

    Has built-in lan and wireless connections.

    Network connections:
    1 - a 1394 connection, disabled so it doesn't complicate things
    2 - a lan connection, disabled so it doesn't complicate things
    3 - the wireless connection; IP address set to 192.168.0.12, subnet
    set to 255.255.255.0, uses Windows to configure wireless settings

    The NOTEBOOK can't access the internet. :(

    ---

    Since the desktop can access the internet, I'm assuming that is set up
    correctly.

    Since both machines are set to the same workgroup, and both machines
    can transfer files, etc, to/from the other machine, I'm assuming the
    wireless network is set up correctly too.

    Can someone tell me what I'm overlooking?

    Okay, I played around with it some more and found a solution. I don't
    understand why it works, but it does.

    I changed the notebook wireless connection so that the IP address is
    obtained automatically. Problem solved. :)

    But in closing, I still don't understand why the IP address I was
    using for the notebook was the (apparent) cause of the problem.

    Anyone know the answer?

  5. Because 192.168.*.* and 10.*.*.* (and I'm pretty sure one other range) are
    private subnets and supposed to be unrouteable outside their own LAN. When
    you used DHCP you were assigned an address on the same network as the
    Internet connection, thus it's routeable.
