Well, I could, finally make it work. ()\\

Unfortunately I have not payed much attention to the iwconfig message :twisted: but finally i could understand what was going wrong.
So i did this passages (hope helps)
iwconfig eth1 ap any
iwconfig eth1 esseid any
iwconfig eth1 mode managed
dhclient eth1
and promptly i got a valid ip address.
thnx you all
