Madwifi - connected to AP but can't get IP

I'm using Madwifi, and I can get my card up, and I can connect to the access point, and scan for access points, but I can't obtain an ip. I know its DHCP, and I can connect over ethernet with dhclient. Any ideas?
I followed this tutorial http://madwifi.org/wiki/UserDocs/FirstTimeHowTo and everything works fine, up untill the point at which I run 'dhclient ath0' . I get this output

Code:

You seem to be picking up an IP address OK. From your post:

Your DNS settings seem to be OK too because when you ping yahoo the DNS lookup seems to work too, so your problem seems to be elsewhere.

Can I get you to post the output of:

Code:

ping 192.168.0.1 route wget http://www.yahoo.com

I couldn't find in the man page an argument to specify the interface for wget, if you know one I can get that output for you.

ah hah!

You've still got eth0 up. The default gateway is being directed through eth0 and (I'm guessing) you've unplugged the cable or something to make sure it's using the wireless network.

Code:

ifconfig eth0 down route add default gw 192.168.0.1

Let us know how you get on.

Kickin'! Thanks that did the trick!
