Airport problems

[ShardAerithes at aol.com]

I got a Dlink DI 514 wireless router for christmas. It's 802.11b. I hooked up my regular computers to it through the ethernet ports, and it all works fine. I get my ibook to connect to the router through airport, but it will only load an ip address that begins with 192. Don't you need a 10. something address to connect wirelessly? Is this router not compatible with airport? Thanks for the help
