OK, that says that MAC device # 00-30-65-27-60-55 has been given IP 
address  . The question is, which of the two devices on the 
iBook (wireless or ethernet) has got MAC address 00-30-65-27-60-55? Is 
it the wireless adapter or the ethernet?

You can check the assigned IP addresses on the iBook itself. Go to 
Terminal and type in this command:
ipconfig getifaddr en0

(that's for the built-in ethernet) or:

ipconfig getifaddr en1

(that's for the wireless adapter).

I have a feeling that you're not actually getting an ip address via 
DHCP for the wireless adapter.... The commands above will test this.
