    Lightbulb Unable to get handshake from airodump-ng

    Hello,

    First of all, I've read every topics on the subject and no solution fixed my issue...
    I'm writting an article for my blog about cracking a WPA key. Unfortunatly, I'm not able to get 4 way handshake.
    I think it is due to driver issues.

    Here are my tries :

    Backtrack 5R3 on virtualbox with ALFA card, driver rtl8192cu. I tried compat-wireless versions 2012-12-18, 2012-09-23, 3.6.8-1. (Every versions patched with mac80211.compat08082009.wl_frag+ack_v1.patch). Tried with aircrack-ng provided by backtrack and the version checkouted from SVN.

    Result :

    Every stations on WPA networks show as "not associated", even my computer connected to my AP.
    Unable to get any handshake.
    Some issues to change card channel, but I fixed it.

    Backbox 3 on virtualbox with ALFA card, driver rtl8192cu (provided by backbox, not patched).

    Result :

    Same as above,
    Every stations on WPA networks show as "not associated", even my computer connected to my AP.
    Unable to get any handshake.

    Backtrack 4 as main OS with the WIFI card of my eeepc, driver ath5k (provided by backtrack, not patched)

    Result :

    Stations are now associated to their networks.
    I recieve ACK when I trigger deauth attack.
    Still unable to get handshake (the computer I'm reauthenticating is at 50 centimeters from my attacking machine)

    My questions :
    Has it something to do with my WIFI card?
    What WIFI card and driver do you use to successfully get that handshake?
    What other tool do you know could I use to get that handshake?
    Could virtualbox have some interferences with my backtrack (latency, etc.) resulting in that issue?

    Please don't respond with links to aircrack-ng website or other posts in this forum... I'm reading all of them since 2 weeks and tried every single proposition on my BT5.

    Note : I've no issue using aircrack-ng to crack WEP keys or reaver to use WPS vulnerability, airodump-ng detect about 162 WPA encrypted AP and 86 (not associated) stations. Of course, I stopped every kind of network management processes prior to start. I also tried few other compat-wireless patches, but without success.

    Can't really think of anything, unless you are actually too close?

    hi nasgektw
    premise:
    I'm not expert & do not use that kind of "driver rtl8192cu"

    my alpha cards are:
    awuso36h (my little opinion fantastic)
    awuso36nh (my little opinion good / very good)
    both work (default) in BT5 (r1-r2-r3) in MY VM (oracle or vmware)
    both work (default) in BT5 (r1-r2-r3) in HDD install

    IF perhaps have your "driver type" refers to ALFAWUS036NHR (model)
    try to give a look here:

    http://trendround.com/Linux/-ALFA-AW...tl8192cu/29782

    used on kernel 2.6.39.4(BT5-r1)

    PS: as long as you have not already seen it!

    bye
