If it was WEP, then yes... But not with WPA AFAIK...


Anyway... I've found WHY it was failing... the ieee tkip module can't acces=
s=20
the arc4 algorithm api... Now since arc4 is loaded (And I've tred loading=20
tkip then ar4, and arc4 then tkip) I haven't found why tkip is broken..

But I have found that if I disable tkip on my access point it all works and=
 I=20
geta  link using aes... (Which uses ieee ccmp that loads the aes api).

I guess I'm working... But a few questions yet to be answered...=20
