    Default Failed Association! Why? (full details)

    Hi all! I was posted this topic in "Backtrack"sector, but I think that I must move here. Here they are a copy of old one:


    Hi there! I have a big problem and really going crazy... I reading and reading,but still cant understand why I cant associate with AP. I write "aireplay-ng -1 0 ..." and receive:

    Sending Authentication Request
    Authentication successful
    Sending Association Request

    and after few messages like this I see:

    Sending Authentication Request
    Authentication successful
    Sending Association Request
    Got a deauthentication packet

    My question is does my wireless card need to be able to do injections, so will be able to do and succecefull asociation? Becouse I am not shure that my card can do injection attacks. Or just explain me possible reasons for failed association. I hope that someone will help me. Thanks!


    P.S. Using laptop Compaq 6715s with wireless adapter Broadcom BCM4311 801.11g. Backtrack4 R2 on bootable flash drive.

    __________________________________________________ ________________________________

    Then one guy told me that I must test my wireless card for injections with aireplay-ng -9 mon0

    __________________________________________________ ________________________________
    Here they are my answer:


    Just right now I test my card with: aireplay-ng -9 mon0

    Injecrion is working!
    Found 4 APs
    Trying directed probe requests

    (one of them is network that i try to crack)
    XX:XX...XX channel... "name"...
    Ping (min/avg/max): 2.688 ms / 13.838 ms / 24.648 ms
    30/30 100%

    Now I want to know what I must write in console to see what is the reason of failed association.

    When I use this method (Use this becouse this is wifi signal with no user! Data grows like clock seconds):

    airmon-ng start wlan0 3
    aireplay-ng -1 0 -e "..." -a XX:XX... -h XX:XX... mon0

    And when receive "Got aut.. packet" i press CTRL+C and what I must write in console to give you information that you want? Probably tcmdump but i don't know parametres after that.

    Second method I use:

    -airodump-ng -c 3 --bssid XX:XX... -h XX:XX... -w exapmle mon0
    -aireplay-ng -1 0 -a XX:XX...XX mon0

    In this case i receive four files on my desktop and which one I must open to see reason of failed association? Or may be I must write somethink in console?
    But you must know that in this case I see different error!! :

    Sending Authentication Request (Open System)
    Switching to shared key authentication
    Read XX packets... (XX- randomly changed numbers)
    (after a while):

    Sending Authentication Request (Shared Key)
    Authentication 1/2 succesful
    You should specify file (-y) with atleast 148 keystreambytes
    Trying shared key fake auth...
    Sending encrypted challenge
    Challenge failure


    Hope this will be enough for solution of the problem. Thanks

    You should read more about associating with an AP...
    Just right now I test my card with: aireplay-ng -9 mon0

    Injecrion is working!
    Found 4 APs
    Trying directed probe requests
    ==> yes it injects.

    I think you should first and only try this on your own AP. Sorry if it is, but one learns to get suspicious around here I think...
    Running both KDE and GNOME BT5 flawlessly. Thank you !

    Are you trying to crack WEP-SKA and not OPN? If so you will need to generate a PRGA XOR file. See http://www.aircrack-ng.org/doku.php?id=shared_key for more details.

    Read IEEE 802.11-2007 standard first.
    Next follow Aircrack-ng tutorials before you are messing with the real thing.
