    Unhappy LinkSys WUSB54GC-problem

    Hello (first sorry for my english)
    I have a problem with my LinkSys WUSB54GC (shown as RT2500?):
    first my commands at the beginning:

    ifconfig rausb0 up
    iwpriv rausb0 forceprism 1
    iwprif rausb0 rfmontx 1
    iwconfig rausb0 rate 1M
    iwconfig rausb0 mode monitor
    airmon-ng start rausb0

    then I use airoscript (h!!p://trac.aircrack-ng.org/svn/branch/airoscript/)
    scan OK;select OK; attack:
    there are two variants of failture:

    if I use the BT2final build in driver:
    he says accociate request successfull
    authentification request successfull
    he repeat these lines often but after some time the :-) was shown (and then he repeat again the lines)
    but i have not 1 ARP packet capturet

    if i use the rt73-k2wrlz-1.1.0 driver (h!!p://homepages.tu-darmstadt.de/~p_larbig/wlan/):
    he say 5 times sending accociaten then he stop and nothing happen (0 ARP)

    i use aircrack-ng 1.0 dev 654 (if i use --test: after 0/30 [or something like this] he stops)

    some ideas? (sorry for my english again)

    1) You need to do a search on this forum for the correct drivers to use (the CVS nightly of the rt73 worked for me)
    2) Make sure that you follow the directions in placing the bin file and ucode in the proper directories

    All of the info is here on the forum

    You might want to try the rt73-k2wrlz-2.0.0 driver.

    I have the same wireless card and using the 1.1.0 driver, I don't have any problems, so I can't offer much advice.

    Have a look at this thread: http://tinyshell.be/aircrackng/forum...?topic=1824.45. It may be of some help.

    that sounds like mac filtering activated for this ap

    try to change your mac before you associate

    Its my AP and there is no MAC Filter enabled

    with the 2.0.0 drivers the same problem (sending authentification... 5 times then nothing) couldt it be that i install the drivers false?
    i use:
    copy the file to root
    tar ......bz2
    cd rt73-2.0.0/Module
    make
    make install

    Which commands do you use shamanvirtuel to get your WUSB54GC working and which drivers? (How do you install?)

    http://homepages.tu-darmstadt.de/~p_...-1.1.0.tar.bz2

    i use this one because 2.0.0 is based on an older driver(dec 06)

    ifconfig rausb0 down
    rmmod rt73
    make
    make install
    modprobe rt73
    ifconfig rausb0 up

    support wpa handshake capturing, ........all is out of the box........(only forceprism wich is disabled by default, because it may cause some pbs)

    i use this card for developing softs so....yes it works

    is there some way to check the following commands:

    iwpriv rausb0 forceprism 1
    iwprif rausb0 rfmontx 1

    i think my card doesnt enable these commands because the card doesnt send in monitor mode (or?)

    I second you with the problem !
    I have the exact same hardware ( linksys wusb54gc ), and BT2.
    the build in driver works fine for fake auth.
    but once i update the driver to 1.0.0 or 1.1.0 (2.0.0 gives me kernel panic) ; aireplay-ng -1 (fake auth) doesn't work anymore
    it just keeps giving me "sending authentification request" and till the 5th times it hangs. Mind you airodump-ng is working though.

    So I did an little experiment with the driver ( all with proper procedure including ifconfig rausb0 down/up, modprobe as root)
    First I did modinfo rt73 and it tells my my default driver that comes with BT2 is 1.0.3.6 CVS
    and I tried deleting the rt2570.ko in /lib/modules/2.620-bT...../extra/
    BT2 has a kernel panic !
    wasn't rt73.ko supposed to be the only module works with aireplay-ng?
    or aireplay-ng mistakenly using the rt2570.ko for Wusb54GC that has a rt73 chip?

    Second test I updated 2.0.0 and it gives me kernel panic right away !

    Third test I updated rt2570 driver to the newest AJPj's rt2570-k2wrlz-1.6.1.tar.bz2 and then update rt73 to 2.0.0 and to my supprise no more kernel panic ! But Fake Auth still doesn't work.


    My last test is, i left the rt2570.ko untouched. and updated the to 1.1.0 and as before aireplay-ng -1 (fake auth) doesn't work.
    what so funny is I installed back 1.0.0 driver from the link in the wiki and which is supposed to be the same as the default driver with BT2 (i checked preivously with modinfo ) and Fake Auth. still DOES NOT work.

    I mean i am a total linux newbie and this driver thing is driving me crazy

    no the driver in bt is a dec 2K6 driver...

    i use allway 1.1.0 version with no pb ??!!!

    i swear that i have inject with native driver (but you need to rfmontx 1 )
    1.0.0 have injection outof box
    1.1.0 add wpa.........and disable forceprism

    2.0.0 is a remastered version of native driver (the one from december 2006)

    so i advice to remove all your drivers with airdriver-ng

    install the new driver by hand or with airdriver-ng
    airdriver-ng install 31

    i really don't understand, because this card is widely used in the world for wep cracking.........;;and i never get such a pb.......maybe you need to disable prism headers because they are known to cause pbs.........
