[P1] Airport problems

[ShardAerithes at aol.com]

As an update, the router is registering the ibooks ip and hostname (icebook) under the DHCP table of connected computers.

DHCP Client Table 
  Host Name IP Address MAC Address Expired Time 
  icebook 192.168.0.101 00-30-65-27-60-55 Jan/02/2004 00:42:02 
  unknown 192.168.0.103 00-08-74-BE-00-46 Jan/01/2004 14:59:56 

Unknown is my pentium 4, the G4 is asleep.

The ibook is leasing an IP, it's recognized by the router, and the ibook works if I hook it up directly to the router through an ethernet cord. It just won't load the internet wirelessly. All help is appreciated!
Thanks
