    Default Long fix for BCM4312... Almost there

    For my Broadcom card to work properly I need it to use the b43 drivers (which will allow it to capture and even inject according to what I have read)

    Anyways I have a BCM4312 14e4:4315 Card which is currently only supported by the unstable b43 drivers (that 4315 means it is lower power or PHY to allow it to run better on netbooks)

    So to make it work I followed a guide on aircrack-ng.org to install compat-wireless which contains dev versions of wireless drivers

    These were the commands they had me run

    Code:
     $ wget http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2.6.tar.bz2
     $ tar -jxf compat-wireless-$(date -I).tar.bz2
     $ cd compat-wireless-$(date -I)
     $ wget http://patches.aircrack-ng.org/mac80211.compat08082009.wl_frag+ack_v1.patch
     $ patch -p1 < mac80211.compat08082009.wl_frag+ack_v1.patch
     $ make
     # make install
    Then after I ran that I had compile b43-fwcutter to extract the latest b43 driver

    so following a guide from Welcome - Linux Wireless I had to run the following to first get the lastest b43-fwcutter

    Code:
    wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-012.tar.bz2
    tar xjf b43-fwcutter-012.tar.bz2
    cd b43-fwcutter-012
    make
    Then to get the lastest version of Broadcom's proprietary driver I had to

    Code:
    export FIRMWARE_INSTALL_DIR="/lib/firmware"
    wget http://mirror2.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2
    tar xjf broadcom-wl-4.150.10.5.tar.bz2
    cd broadcom-wl-4.150.10.5/driver
    sudo ../../b43-fwcutter-012/b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta_mimo.o
    * I am comfortable with linux, but compiling is still a little weird for me so I basically ran exactly what is quoted here *

    Now I know I definitely did something because when I boot up i get the message as it loads the hardware drivers:

    ERROR b43-phy0 FOUND UNSUPPORTED PHY

    So I feel like I am on the right track but am at a loss here, can someone with more experience shed light on what I need to do to properly use these drivers...

    Any help would be amazing thanks

    Broadcom drivers are real tricky.
    Make sure you verify the compatibility list here:

    Thanks for the post Muts. It's unfortunate that the 4312 card doesn't work with BT4 final. I'm debating going back to BT4 Pre-final because it supported the card out of the box..

    Ok so how well does that card work in backtrack 4 pre-final, does monitor and or injection work. And I feel like what I did got me so close any last thoughts of what I am missing I have read that entire link given by muts I feel it must be possible

    I'm not sure. If I'm working on a wireless network I use my RT73 w/external antenna. My broadcom was only used for random web browsing.. But I'm about to go back to Pre-final because I don't see enough changes in Final that would make me keep it..

    can you paste the result of lspci |grep Network.

    I ve a 4312 which works nice, injection too.

    BCM4312 14e4:4315

    It is the revision for low powered comps (primarily notebooks and netbooks in my case)

    What revision did you get working?
