OK, then this is a routing issue not a hardware issue.

Just for the halibut, shut down another machine. Assign this one that
IP and see if it works. That would remove any possibility of the
router only allowing certain clients through, and so on and so forth.
Have a peek at the router and just see if anything leaps out at you.

I figured, just trying to think of things.

If you trace something, anything unusual pop out at you? You should
get stopped at your local router, from what you say. ping something
from another computer, getting the ip address, then try the same by ip
address on this one. Could be dns issue?

I have experienced where a pcmcia card will prevent my laptop from
booting. Slip it in after booting, and some things are still brain
dead (firewire, problematic anyways), but the usb2 started working.

Do you happen to have a usb network adapter around? Can you throw it
on just to see if you do get connectivity? Even 1.1 should do you fine
for the internet. If you want to do significant transfers between
machines within the house, you'll hate it, but some connectivity is
better than no connectivity.

Even better, if you happen to have a doc, and it has a card slot, can
you slap a pci nic in?

You're not trying to use a cardbus pcmcia card in a non-cardbus pcmcia
slot are you? Or ... I forget if you need both cardbus and pcmia stuff
loaded, or if pcmcia now just comes cardbus, and supports non-cardbus
just for legacy's sake.

Probably your fastest answer is to load a buntu live cd. They seem to
come with such a bevy of hardware support out of the box, maybe you
can prove whether it's a hardware or configuration issue.
