I'm happy to be wrong about this, but if you are getting an IP address
from your DHCP server then you have certainly established layer 2
connectivity, which means that the suppliant is working.  Take a look
at the wpa_supplicant debug logs to verify.

What happens when you ping the gateway, forcing ping to use wlan0
(sudo ping -I wlan0 <gw_ip>).
