    Question IWL3945 with Backtrack 4 - Nope, that's not working!

    Hi Everyone,
    I have been using Backtrack since BT2beta, cracked a lot of WEP with it, and always liked it. But now I am stuck with a stupid problem:
    The wireless card is an Intel 3945ABG, the driver is iwl3945 and I am using BT4 final.
    I fire up the card with the well known:
    airmon-ng start wlan0

    It starts up perfectly, mon0 enabled as monitoring interface.
    I use airodump-ng, works perfectly. I fake authenticate with aireplay-ng and it works. BUT any attempt to actually attack the AP (chopchop, fragmentation, ARP replay or interactive) fails. The AP has no MAC filtering enabled, or nothing like this... The funny thing is that the -9 (test) shows that injection is actually working, but in the reality IT DOES NOT.

    The commands I use (I don't think you will find any syntax mistakes, I have done this many times before):
    aireplay-ng -4 -h MYMAC -b APMAC mon0
    aireplay-ng -5 -h MYMAC -b APMAC mon0

    Oh, and i tried to do the same using wlan0 instead of mon0 - no success of course.

    Anyone can tell me, what is messed up in BT4? I remember in BT3 it worked with the IPWRAW driver...

    Thanks,
    DOMy

    I know this topic has been covered, but I will attempt to help. Perhaps a dumb question, but did you try to follow all of these steps?

    simple_wep_crack [Aircrack-ng]

    I have not had any problems getting the 3945ABG to work in BT4.

    Well, I tried the tut step by step and still, no success at all...

    Are you sure it worked for you? Did you do anything special? Loading different drivers for example?

    Worked without issue from the start. Can you post the exact errors you are seeing, or provide a little more info? What happens when you try to inject?

    Try something like this:
    Code:
     aireplay-ng -1 0 -a AP BSSID mon0
    aireplay -3 -b AP BSSID mon0
    And you could give us some output, like the error it gives you ...

    Hey Gus,
    Sorry for getting back to you so late, but I was trying and trying really hard in these days to get it working.
    I even returned to Backtrack 3 because I thought injection works in BT3.

    Well, right now I have the following problems:
    BT3: ipwraw driver loaded, neither ChopChop nor Fragmentation attack works (I don't want to use the -3 attack, because I need to demonstrate all the attacks on WEP for my students)

    BT4: default drivers, FakeAuthentication works, but no ChopChop or Fragmentation...

    Both of them simply fail, chop chop gives me the well known failure message ("ChopChop failed, possible reasons: blah blah blah"), Fragmentation keeps trying but fails with any kind of packet...

    I just simply don't know what to do. My laptop is a Fujitsu-Siemens Esprimo V5505.

    Any help would be really appreciated.


    BTW:
    In BT4 carwhisperer doesn't work either. I am pretty sure this is because of the new version of bluez (bluez-4), but it is such a shame, that no one has even tried to fix it...
    Returning to BT3 solved this problem....
