WUSB 2.6 + Apple Airport

Hello, and apologies if this is a FAQ.

I've got a Linksys WUSB 2.6 and I'm trying to connect to my Apple Airport 
(original, non-extreme) network.  I'm running Debian 2.4 with a newly 
compiled kernel (had to disable SMP -- any news on that front?).

By enabling WEP using the lvnet utility, I can get the device associated 
with the network.  I'm now stuck trying to figure out how to get DHCP to 
assign me a network address; dhclient eventually times out with "No DHCP 
offers received".

I also realized that I've not been prompted for my Airport password at any 
point, but I can't see where to configure this.

This may be more about my lack of knowledge about DHCP, but any help 
getting online would be appreciated.

Regards,

Wes
