Hi! sorry for this other email, i've forgot one thing..

iwconfig:

wifi0     IEEE 802.11b  ESSID:"S.Severa_net"
           Mode:Master  Frequency:2.422 GHz  Access Point: 00:02:8A:A0:83:D6
           Bit Rate:11 Mb/s   Sensitivity=1/3
           Retry min limit:8   RTS thr:off   Fragment thr:off
           Encryption key:B226-EDF1-0C08-080E-4FA7-5296-5A   Security 
mode:open

           Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
           Tx excessive retries:0  Invalid misc:0   Missed beacon:0

why the Access Point is 00:02:8A:A0:83:D6 that is the MAC address of my 
wifi?? I cannot understand it! i tried to do

iwconfig wlan0 ap 00:12:bf:03:d1:c1

that is the MAC address of the WLAN of my router, but nothing change.. why?
thanx
