well, to me this looks as if the wlan simply is not connected, have you 
set the ESSID yourself or by a script or came it with assicoation?
also what does 'iwlist ath0 scan' show?
you can without a problem open your tp and look if there are two thin 
(~1mm) cables which go from the display to yout wlan-card (grey ones i think
