Thank you really much for your answer !!
I tried 2009_1204_RT3070_Linux_STA_v22.214.171.124 and replaced the file you attached... but still no luck.
By the way it was something very similar to what I already tried... but no success
The only thing I can get is WLAN1 (by doing iwconfig). I can't see any RA0 like i saw the first time i changed to samsung id's.
I think i'll soon give up... i really don't know what to do more... if you know anything useful pls let me know
In the meantime... thank you
