[Cube] Airport Issues

[Francois Barbary]

Hey All!
Long time subscriber, used to contribute alot, but ever since i got my  
macbook, i haven't had the connection i used to with the cube  
comunity... anyway... im trying to set up my cube in another room, but  
the airprot card seems not to be working properly... i used to use  
ethernet... any ideas how to check the hardware for malfunctions?  
basically it's like the airport card doesn't see any wireless networks  
at all1

THanks ,
Francois
