Run it in the foreground with degugging on, and you'll see a success 
message (or not)

Is the dhcp server directly connected to the wlan? If so is it 
authenticated and connected properly? If not, how is it connected? OTOH 
you said in a previous post that under windoze it works, so the other 
parts of your net should be ok.

If your system uses ifup when it boots, you may want to see if there is 
a dhclient on ath0 running already in the background. If so try killing 
it first, do an ifconfig ath0 down, then ifconfig ath0 up, and then 
wpa_supplicant, dhclient ath0.
