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

[chenxiaolong]

I'm almost 100% sure that the reason it's not working is because you don't have the b43 firmware installed . Here's how you can install it:

You can install the deb package attached to this post (I packaged the files that are installed from the commands below) or you can run these commands:

wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-013.tar.bz2
tar xjf b43-fwcutter-013.tar.bz2
cd b43-fwcutter-013
make
cd ..
export FIRMWARE_INSTALL_DIR="/lib/firmware"
wget http://downloads.openwrt.org/sources/broadcom-wl-4.178.10.4.tar.bz2
tar xjf broadcom-wl-4.178.10.4.tar.bz2
cd broadcom-wl-4.178.10.4/linux
sudo ../../b43-fwcutter-013/b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta.o

And a restart should get your wireless working .

EDIT: [Forgot to attach deb file]

My monitor mode isn't working. I did everything as described on the first page, but it still isn't working, when i start monitor mode in aircrack-ng it works for maybe 30 secondsa and then stops. airodump cannot detect any APs it just freezes

Any thoughts ?

here's the output

Hi i'm new here,

first time i use b43, this driver support with my ubuntu, although it manually configured (coz NetworkManager can't detect my BCM4312)..

vostro@vostro-laptop:~$ uname -r

2.6.32-21-generic

And I can use it for monitoring mode(kismet and aircrack-ng)
After one night stay collecting data in monitoring mode, b43 cannot drive my wireless again,,

the kernel says:

may kismet or aircrack can make b43 like that?

It was solved my self by upgrade to kernel 2.6.34-020634-generic
kismet worked...but after capture 2-4 minutes, kismet became freeze

any idea? please

I also got the same problem, kismet, airocrack, wireshark ... stop working after 30 sec. I wonder if there is anyway we can fix this driver?

Yes - me too. Stops working between 30s and 2mins, but sometimes it will run AIRODUMP-NG for 20 mins. When I start AIREPLAY-NG, it hangs.

Mine is a WUSB100 v1.

Stops on the following:

backtrack 2.6.28.1 - rt2800usb
backtrack 2.6.30.9 - rt2870sta
ubuntu 2.6.32-21-generic - rt2870sta (staging)

Tried ralink's latest rt2870sta - doesn't work at all.

Thanks so much for helping get my Ubuntu 10.04 Netbook wireless working!!!
However how do we get monitor mode back on?
thanks in advance

[ghinix]

Ok going for another attempt to get the Broadcom bcm4312 rev 01 working again (using this process by “chenxiaolong” seemed to work)...

…hopefully this time my dvd drive won’t be so loud and noisy. Any ideas what could be causing the laptop dvd drive noise?

Thanks so much!

2.6.35 is out. Does it work with DMA now? Some tests?
