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

[mrcatzilla]

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).

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.

sudo rmmod b43
echo "blacklist b43 | sudo tee -a /etc/modprobe.d/blacklist.conf

2. a. Remove the firmware package (if you installed b43)

sudo apt-get remove b43-fwcutter

OR b. Remove the firmware files

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

sudo gedit /etc/modprobe.d/blacklist.conf

4. Reboot

Hope this works.

Hey I'm so sorry if I caused any trouble, just wanted to try something new.

[chenxiaolong]

No trouble. I'm happy to do anything that helps.

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

Great post

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:

eth1: broadcom BCM4315 802.11 Wireless Controller 5.10.91.9

but lspci shows:

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!!

For those of you who use karmic, compat-wireless need not be compiled.

sudo apt-get install linux-backports-modules-karmic linux-backports-modules-wireless-karmic-generic b43-fwcutter

is enough.
Then do

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

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

Then

gksudo gedit /etc/modules

and add

b43

to the end of the file
