It connects great for my linux and win98 machines.

 I set up the TCP/IP with the same settings as I would on my other computers.

What sort of network hardware do you have?  What speed is each network
interface, and what speed is your hub?  Is it a dumb hub or a switch?
At what speed/duplex is each interface actually running?

Try doing a large file transfer between the Mac and the router.
If throughput is dismally slow, you may have a duplex mismatch somewhere,
probably on the iBook's Ethernet interface.  You can also confirm this
by running 'netstat -i' or 'netstat -s' on the router and looking for
high error and retransmission counts.
