  Okay, that's clearer.

  This suggests that AOL's system has learned the MAC (hardware) address of
the XP machine's network card.  Can you plug the 98 machine in directly?
Does it work if you use the XP machine's network card, and not if you don't?
 (It may not be convenient to perform these experiments.)

  USP?  I think you mean either UTP or USB, and I hope it's UTP.

  Bill Cohane has already addressed this, I think, but basically the device
(router or XP) that's plugged directly into the cable modem will get a
10.x.x.x address on the cable network side.  When it's the router, the LAN
of router, XP, and 98SE is a separate network that needs its own private
addresses, and the 192.168.x.x range are commonly used for this.

Suggestions:

  On the router configuration, make sure that the cable modem is on the
"WAN" port and the XP box on the "LAN" port.  Make sure that NAT ("Network
Address Translation") is turned on.
  On the XP box, run "ipconfig" from a command-line prompt to find out the
"gateway" address.  Use the "ping" command to make sure the machine can
reach that address, and get responses back from it.
  Try pinging www.yahoo.com.  If that doesn't work, the message may help us
understand if there is a further problem.

  You *might* have to find out the MAC address of the XP machine's network
card, and tell the router to use this address on the cable network.
