Hi Teilhard,

Is it this type of chipset? Atmel at76c50x?

I see its in the mainline kernel.  Makes a module called atmel.ko.
Have you got the correct firmware image in /lib/firmware or somewhere
similar?  

This website seems to have the firmware images for the at76c50x (and
probably some newer ones, i didnt check)

http://www.thekelleys.org.uk/atmel

Also did you try "/sbin/iwconfig wlan0 key open" before entering the
network key?  I think it probably defaults to open but I do it in my
configuration.


Best regards, 

Alastair
