    I don't know what you're talking about, the proprietary driver works just fine work normal wi-fi usage (including WPA-WPA2)
    No wlan0, so no kismet though. That's my initial goal with the card, and that's why I ended up buying another one (should arrive in a week or two, ordered, unfortunately, from Hong Kong).

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

    I need help (Linux Noob)
    I realized that my wireless drivers stop working... but too late and would like to undo my mistake of doing the tutorial listed here (I find nothing wrong with it, but I don't know what I'm doing) and want to go back to before I did the driver installation with just the regular drivers and all.

    Will someone please help me reverse the process

    To revert back to the wl driver:

    1. Unload and blacklist b43 driver.

    Code:
    sudo rmmod b43
    echo "blacklist b43 | sudo tee -a /etc/modprobe.d/blacklist.conf
    2. a. Remove the firmware package (if you installed b43)

    Code:
    sudo apt-get remove b43-fwcutter
    OR b. Remove the firmware files

    Code:
    sudo mv /lib/firmware/b43 /lib/firmware/b43.backup
    sudo mv /lib/firmware/b43legacy /lib/firmware/b43legacy.backup
    3. Remove the "blacklist wl" line from /etc/modprobe.d/blacklist.conf

    Code:
    sudo gedit /etc/modprobe.d/blacklist.conf
    4. Reboot

    Hope this works.

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

    Worked for me with the following...

    So I followed the main steps in the starting section using my 14e4:4315 that comes inside my hp mini 1100...
    I had a fresh install and a fresh update using the ubuntu netbook remix.
    My kernel version is 2.6.28-16-generic.
    So here is what worked for me...

    Code:
    sudo apt-get install gcc g++ gawk make automake flex bison binutils cmake autoconf

    Downloaded the compat drivers below...

    http://linuxwireless.org/download/compat-wireless-2.6/
    You can't use wget for this because they have a hotlink prevention system. So just download the
    Quote:
    compat-wireless-2.6.tar.bz2
    file from that website and saved it to /usr/src

    Then open the terminal and run this command to extract the archive

    Code:
    tar xjf compat-wireless-2.6.tar.bz2

    In order for the package to compile, you need to install the kernel headers, if not already installed. Run this in the terminal ( Already had mine from netbook remix) But after the kernel update from -11 I went ahead to avoid confusion and did

    Code:
    sudo apt-get autoremove

    Code:
    sudo apt-get install linux-headers-$(uname -r)

    Then change to the compat-wireless directory:

    Code:
    cd compat-wireless

    Then compile the source files:

    Code:
    sudo make

    Then install the files:

    Code:
    sudo make install

    Then unload the drivers

    Code:
    sudo make unload

    Then install b43-fwcutter:
    VERY IMPORTANT!!: Do NOT choose yes when it asks if you want to automatically fetch the firmware.

    Code:
    sudo apt-get install b43-fwcutter

    Download the Broadcom firmware files

    Code:
    wget http://mirror2.openwrt.org/sources/b...0.10.5.tar.bz2

    Extract the archive

    Code:
    tar xjf broadcom-wl-4.150.10.5.tar.bz2

    Change to the driver directory

    Code:
    cd broadcom-wl-4.150.10.5/driver

    Install the firmware

    Code:
    b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta_mimo.o

    The firmware install Directory I used was /lib/firmware/

    Then blacklist the proprietary driver

    Code:
    echo blacklist wl | sudo tee -a /etc/modprobe.d/blacklist.conf

    after this all I did a reboot

    I wanted this to work so i could use aircrack-ng so I installed this next to verify the driver worked correctly with monitoring sooo...

    Code:
    sudo apt-get install aircrack-ng

    Code:
    sudo airmon-ng wlan0

    wlan0 now becomes mon0 for me at least

    Code:
    airodump-ng mon0

    My card is seeing and able to capture traffic

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

    Hi, ive got a quick (and probably stupid) question about this whole process.

    I read that karmic just had come out, so i thought i'd upgrade, but found out that my wireless stopped working. Ive been through this entire thread looking for a solution, but im not sure that i need to install any drivers, or firmware - here is why.

    In karmic, network manager says that my wireless is disabled (don't know how to enable, but ive tried a bunch of things), pretty sure it has something to do with loading wrong drivers. The weird part is dmesg has this little gem:

    Code:
    eth1: broadcom BCM4315 802.11 Wireless Controller 5.10.91.9
    but lspci shows:

    Code:
    Network controller: Broadcom corp BCM4312 802.11b/g
    anyways, i dont know if this is even relevant, just seemed weird.

    During boot, if i boot into the previous kernel version (2.6.28-16-generic) the wireless works, but for some reason the mouse on my laptop doesnt, so i cant really use this.

    Is there a way i can just use the drivers that work in the older kernel version?

    Any insight is greatly appreciated!!

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

    For those of you who use karmic, compat-wireless need not be compiled.
    Code:
    sudo apt-get install linux-backports-modules-karmic linux-backports-modules-wireless-karmic-generic b43-fwcutter
    is enough.
    Then do
    Code:
    sudo modprobe -r wl
    sudo modprobe b43
    and you're done. If it works and you want to make the change permanent :
    First, blacklist the wl module
    Code:
    echo blacklist wl | sudo tee -a /etc/modprobe.d/blacklist.conf
    Then
    Code:
    gksudo gedit /etc/modules
    and add
    Code:
    b43
    to the end of the file
