Broadcom 43xx su Ubuntu Hardy

Su http://ubuntuforums.org/showthread.php?t=738216 ho trovato la soluzione al mancato fuzionamento della scheda wifi Broadcom 4312 installata sul notebook HP 6720s.

Ecco i passi necessari (lievemente corretti rispetto a quelli del post originale):

sudo apt-get install build-essential
cd /usr/local/src
sudo wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-011.tar.bz2
tar xjf b43-fwcutter-011.tar.bz2
cd b43-fwcutter-011
make
cd ..
export FIRMWARE_INSTALL_DIR=”/lib/firmware”
sudo wget http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2
tar xjf broadcom-wl-4.80.53.0.tar.bz2
cd broadcom-wl-4.80.53.0/kmod
../../b43-fwcutter-011/b43-fwcutter -w /lib/firmware wl_apsta.o
sudo reboot
