Yesterday I installed Kubuntu Lucid Lynx Alpha 3 onto a Gateway m675prr laptop, which was made on 1/5/2005, almost two computer generations ago. Some chips which were previously supported by applications are now supported by the kernel. The ICH5 sound chip was recognized and KMix shows various controls but there appears to be a bug in the 32 kernel that prevents these older chips from working correctly.

The Broadcom 4306 (Rev 3) wireless chip in that Gateway was not recognized by Lucid. The "Hardware Drivers" menu option, with the aid of a wired connection, ran the b43-fwcutter app but failed to start the wireless chip. I completely uninstalled the b43-fwcutter and used the method given at the Kernel website. It has two b43xx options, those for Rev2 and earlier (b43legacy) and those for Rev 3 and later (b43). And, within each category, instructions specific for the version of kernel being used.

I also rmmod'ed ssb and b43:
sudo rmmod b43 ssb


The b43 page gives thorough instructions for downloading two applications and compiling them. If your attempt to compile b43-fwcutter fails it is probably because you don't have gcc installed. Install it, delete the directory created by untarring the b43-fwcutter tar, and redo the untar. Continue with the detailed steps on compiling the firmware cutter app and the actual driver app. Don't let the idea of compiling an app deter you. The steps in this case are very simple! In fact, you can copy&paste them into a konsole.

You are using the b43 driver from linux-2.6.25 or newer

Follow these instructions if you are using the b43 driver from linux-2.6.25 and newer or compat-wireless-2.6, or from any current GIT tree.

Use version 012 of b43-fwcutter.
Download, extract the b43-fwcutter tarball and build it:

wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-012.tar.bz2
tar xjf b43-fwcutter-012.tar.bz2
cd b43-fwcutter-012
make
cd ..

Use version 4.150.10.5 of Broadcom's proprietary driver.
Download and extract the firmware from this driver tarball:

export FIRMWARE_INSTALL_DIR="/lib/firmware"
wget http://mirror2.openwrt.org/sources/b...0.10.5.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

Note that you must adjust the FIRMWARE_INSTALL_DIR path to your distribution. The standard place where firmware is installed to is /lib/firmware. However some distributions put firmware in a different place.

Once both compiles are done, and the second gives a message about creating a bunch of files, you have two more commands to do, which the web site doesn't mention:

sudo modprobe b43

(the wifi light should come on)

sudo depmod -a

(allows for automatically turning on the wireless during boot up.)

That wireless.kernel.org web site is a great place!
