yes.   Swapping wires to and ports on the router as well as removing the
other computers from the network didn't help either.

No effect.

The problem remains.

I thought so too.  I didn't even consider it as a possibility...

I used tcpdump since I didn't have to download it.  I don't understand
most of what it told me but there was some weird stuff in there -- like
what appeared to be the router broadcasting a message asking for the
router's address.  That sent me into the router's configuration menus.
It's been years since I looked around in there.  For some reason, the
"static routes" table had an entry for the address it is assigning to
the new computer.  I took that incorrect information out and the network
is working as it should.

Right now, I'm really impressed with Fedora 9.  Even with a computer
newer than the OS, it installed and everything works without having
asked me a single, hardware-related question.

Thanks for your help.
