    >What exactly do you mean by "gets through to the router"?
    Without more
    >information, here are a couple of things to think about:
     
    Opening up Konqueror on the desktops immediately allows
    Internet access
    through the Linksys 80211B router and the cable modem. Not
    so with the
    Toshibo Satellite 4030CDT, which has 9.0 as do the desktops
    on this home LAN.

    I originally set up the hosts manually using 172 numbers. I
    am not sure,
    but I think the router/DHCP ignores them and assigns the 192
    numbers?????

    I have not seen any.

    I did that several times as you suggest, but no joy.
    Situation persists.
    The xircom card feels very hot sometimes. At bootup eth0
    fails. I can
    bring the green light on with ifconfig eth0 up 192.168.1.107
    and ping
    other hosts by their hostname.

    After I get access again, I can ping the DNS server numbers
    just given
    me by my ISP.

    There is a dongle in another pc , but I dont know beans
    about wireless yet.
    The laptop had a linksys pcmcia card which was recognized by
    cardctl,
    but I have removed it and its config. Hope these are
    reasonable responses.
