    Packet injection with b43 driver


    Hi, I'm trying to enable packet injection with my broadcom card, and I have some confusion that you may be able to clear up.

    It says here that packet injection should work with the standard b43 driver.

    However, when I run the packet injection test with aircrack-ng, as found in the guide here, I do not get the message saying packet injection is working.

    I know that there have been patches made for b43 and bcm43xx, but my understanding was that they made packet injection faster, not enabled packet injection.

    So is something wrong with my driver? I would try applying the patch, but I do not have the sources for the b43 module and I'm not sure where to get them. The directory /usr/src/kernels/2.6.24.5-85.fc8-x86_64/drivers/net/wireless/b43 lists only Kconfig and Makefile, there is no main.c or anything else.

    So my questions:
    -What is going on with my driver?
    -How can I get the sources for my driver?

    Thumbs up related situation

    I'm also trying to use packet injection.
    linuxwireless.org/en/users/Drivers/b43#fw-bcm43xx

    Use the B43 driver.
    Then disable the wireless card if you are using it for internet, keep this page up to read then disable it. Then in command, change to monitor mode:

    sudo iwconfig wlan0 mode monitor
    Then test for packet injection if using B43 driver:

    aireplay-ng -9 wlan0
    It should work, but I can't get mine either.
    My terminal window returns to me:

    aireplay-ng -9 wlan0

    I just noticed this post was created a year before my reply. I can't believe nobody has responded to this, especially on this outspoken forum!

    I guess that I don't understand what packet injection is used for. Could you enlighten me?

    well data is sent via in packets, groups of bytes. injection - well basically forcing packets until you can crack a wireless key to join a network / free wifi. not necessary if neighbors don't use keys on their routers, lol.
    Always check out the wiki for more info:

    It is illegal to access a computer network without first getting permission to do so. This is true whether it is password protected or not. We will not promote illegal activities at Linux Forums.

    It is also against the forum rules to post spam posts. That is what you did to get around the rule preventing new members from posting links.
