So you like Debian, and why wouldn’t you, it is great after all. Unfortunately, many laptops come from the factory sporting Broadcom-based chipsets. So inevitably I complete a Debian install and Broadcom takes the wind out of my sales. I then trudge over to http://wiki.debian.org/wl#Squeeze and go through the paces. Why? I do it over and over. Well enough is enough, I mean this isn’t a tricky script to write. So for your enjoyment, I have put it all together into a small bash script to simplify things for future installs. First, be sure to add the non-free repo to your /etc/apt/sources.list file.
Then create and run a .sh file containting:
aptitude install module-assistant wireless-tools
m-a a-i broadcom-sta
echo blacklist brcm80211 >> /etc/modprobe.d/broadcom-sta-common.conf
update-initramfs -u -k $(uname -r)
modprobe -r b44 b43 b43legacy ssb brcm80211
