I'm using Ubuntu 10.04.4 LTS, and in my laptop there is a Broadcom BCM4312 WLAN card.
lspci output:

04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)

    Kernel driver in use: wl  
    Kernel modules: wl, ssb

So as you can see, the current (and default) driver is wl - installed with Jockey.
But I have another Ubuntu based distribution on my laptop (BackTrack linux), which is also 10.04, but it has the b43 driver installed and the overall performance is much better. So I would like to install it on this OS too, but even google didn't help me.

So my question is how to install the latest b43 driver on my Ubuntu?

  • How is it in ubuntu 12.04? the aim is to activate the possibility of an Accesspoint - b43 would support this... wireless.kernel.org/en/users/Drivers/… wireless.kernel.org/en/users/Drivers/b43#Ubuntu.2FDebian - the hardware must be able to do this because under windows i can use the trial version of connectify.me and my android phone recognize the wpa-wifi-accesspoint but not the wep-accesspoints made by ubuntus networkmanager... that's realy interesting

Reset to default

Type in a terminal:

sudo apt-get install b43-fwcutter

Under the desktop menu System > Administration > Hardware/Additional Drivers, the b43 drivers can be activated for use.

Restart.

Edited:

Install dkms.deb, patch.deb, fakeroot, and bcmwli. Those packages are in Ubuntu installation CD in the following paths:

/pool/main/d/dkms.deb
/pool/main/p/patch.deb
/pool/main/f/fakeroot
/pool/restricted/b/bcmwli

Enable STA driver in additional driver.

sudo modprobe -r b43 ssb wl
sudo modprobe wl

  • b43-fwcutter is already installed, but still it isn't in use. And jockey-gtk only shows the current STA driver. "These package contains Broadcom 802.11 Linux STA wireless driverfor use with Broadcom's BCM4311-, BCM4312-, BCM4321-, andBCM4322-based hardware."

  • Is it not listed in Additional Drivers? What does sudo modprobe b43 give?

  • Ok, now it worked! Thanks for Your help!!! I installed those packages from the CD, but I deactivated the STA driver (You sad to activate), and I wrote sudo modprobe b43 instead of wl, and now it works. Thanks again!
