Something in /var/log should show dhcpcd or dhclient sending requests. 
It probably won't show a reply.  Wireshark should show the 
same--requests go out, nothing comes back.

Beyond that you'd have to look on the AP side, which may not say 
anything obvious via the web interface (though you might see the DHCP 
requests on the wired part of it, if that's bridged to the wifi).

I've had problems like this.  Either wlan0 is lying when it says it's 
associated or the problem is on the DHCP server side of things.  I 
haven't had any access to investigate.
