    Default HOWTO: Use b43 driver with 14e4:4315 (Broadcom bcm4312 rev 01)

    So injections work with b43. I can't get it to allow my 4311 to go into promiscuous mode. Is the b43 driver is capable of that? When I was on Ubuntu, I had the restricted STA module, which worked great, but I can't seem to find out how to do it on BT4. All of the manuals explain the wl module, which is what is currently in use, by default. Could you let me know?

    sudo ifconfig eth1 down
    sudo iwconfig eth1 mode monitor
    sudo ifconfig eth1 up

    That should do it. To go back do the same thing, but change monitor to managed.

    That's what I've got, it's 4311 versus 4315. I don't think there is much of a difference, but as long as it works. I'm just a little weary of b43, because I caught hell getting it to work in ubuntu. I had trouble going from one mode to another with the wl driver. I just upgraded it based on the STA package given by Broadcom, which covers your version as well. But I haven't started playing with the iw-tools yet. I'll go give it a try.

    Default 14e4:4315 works with aircrack?

    Hi there,
    does it really mean that Broadcom with PCI ID 14e4:4315 really works with aircrack suite?

    Because on aircrack-ng.org you can read that most Broadcom will work except this one ....

    Has anybody made expierence - and what aircrack-suite version did you use?


    Cheers

    Works great...but with kernel 2.6.31 as with Ubuntu 9.10. See this post:

    http://forums.remote-exploit.org/new...-question.html

    I used svn aircrack-ng and svn airoscript-ng.

    Thanks for all the feedback!

    I installed Ubuntu 9.1 to have the latest kernel -

    But unfortunately I only get an additional eth1 interface (which works as WLAN) but Airodum brings an erroro message that the ARP Type is ethernet and not wireless! Any ideas?

    Does anyone have a cookbook from the scratch? I think I am doing some wrong at a special point - but I dont know where

    Cheers
