    Default Fake authentication problem , any help ?

    Hi,
    i am newbie, I have toshiba tecra with the intel wireless card 5100 and runing bt4 , i got strange response when testing injectiong . i used (# modprobe -r iwlagn & # modprobe iwlagn swcrypto50=1) , when testing injection with aireplay without specifing any access points , i got injection working message , and the percentage in some access points reaches 100 % , but i can't find my access point(thomson speedtouch ) within those ones .If i put my essid or bssid in the arguments of aireplay , i don't get the success message unless i activate airodump !! .
    so i activate airodump and try the fake authentication ,but i got the following message.

    20:13:18 Sending Authentication Request (Open System) [ACK]
    20:13:18 Authentication successful
    20:13:18 Sending Association Request

    20:13:23 Sending Authentication Request (Open System) [ACK]
    20:13:23 Authentication successful
    20:13:23 Sending Association Request

    ************ the Above message is repeated 4 more times then i get
    20:13:48 Sending Authentication Request (Open System)

    20:13:50 Sending Authentication Request (Open System)

    ************* then this message is repeated until i get the following message

    * Perhaps MAC address filtering is enabled.
    * Check that the BSSID (-a option) is correct.
    * Try to change the number of packets (-o option).
    * The driver/card doesn't support injection.
    * This attack sometimes fails against some APs.
    * The card is not on the same channel as the AP.
    * You're too far from the AP. Get closer, or lower
    the transmit rate.

    when i try aireplay to make same attack again i got the " 20:13:50 Sending Authentication Request (Open System)" message
    But if i used (# modprobe -r iwlagn & # modprobe iwlagn swcrypto50=1) again and restarted airodump , i got the long message with the authenication successful .
    I search alot and got no success,i will appreciate any help.

    normally i'd agree but based on this statement

    and the percentage in some access points reaches 100 %
    i think his problem is he's to far from his neighbors wifi
    Using backtrack for the first time is like being 10 years old again with the keys to a Ferrari.
