    Default Broadcom 4311 support in BT

    After checking this page hxxp://bcm43xx.berlios.de/?go=devices, the Broadcom 4311 is supported in the 2.6.20.6 and later kernels. I checked BT and it uses the 2.6.20-BT-PwnSauce-NOSMP. My question is, does the BT kernel support the Broadcom 4311. I've tested it for injection and it doesn't work. I had a similar problem, though, with the WUSB54g wireless card but was able to find a workaround.

    Injection is not supported.

    The page that you refer to, says that the bcm43xx is patched for injection. Is that incorrect?

    The page does say that. However, Broadcom support is sketchy at best, and you can see from the Wiki entries that not many (if anyone) people have gotten it to work.

    yep...i got one and you can see it's not working well if you do a --test attack on it that


    aireplay-ng --test eth0 >>> will say you it's working

    BUT

    if you have 2 cards you can test attacks....
    eth0 is card we want to test , ethX is a card wich will act as an ap

    aireplay-ng --test -i ethX eth0

    you can see with this command that none attack except fakeauth are working...............

    so injection is not working really.....
    Watch your back, your packetz will belong to me soon... xD

    Is there anything we can do to make this driver capable of cracking a WEP key or use aireplay?

    Yes there is, you could either

    Re-write the driver and make it work properly
    or
    Wait until the people who wrote the driver fix the problems

    Ok since i even have to ask i know that im not capable of doing it, but would you mind giving me some info on what i would need to do to make it be able to perform injections?

    Try using aircrack-ng v0.9.1. If memory serves me, I think the broadcom 4311 will do everything but the fragmentation attack.
