i can successfully activate wep by executing :

iwconfig wlan0 key s:bs151

and get :

wlan0     IEEE 802.11-DS  ESSID:"test"  
          Mode:Master  Frequency:2.422GHz  Access Point:
          Bit Rate:2Mb/s   Tx-Power:-6 dBm   Sensitivity=1/3  
          Retry min limit:8   RTS thr:off   Fragment thr:off
          Encryption key:6273-3135-31   Encryption mode:restricted
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:7  Rx invalid frag:0
          Tx excessive retries:3  Invalid misc:6   Missed beacon:0

However, when using ethereal to sniff on wlan0 i discovered every packet is non-encrypted (telnet logins and passwd go straight through)...

Am i fooled because the driver (soft-or hardware) already decrypted the packages?
