Three people already answered your previous post... 

I shall , however reiterate my answer - it is pasted below, including the
whole post, in case you missed it somehow.

Have a look here:


There is also a package called "bcm43xx-fwcutter " in the universe
repository: - it downloads the micro-code/ firmware and installs it.

So, you might not have the universe repository enabled. See




...   but I suggest that you use the package from cafuego's URL above. It
works well on my iBook G4 with a bcm 4306 card.

 Note that if you install the firmware from cafuego's repo
you will not need fwcutter ( his deb installs the firmware) .
