Ubuntu Intrepid (8.10) replacing ath9k by madwifi

I had many problems using the new Ubuntu Intrepid Ibex (8.10). The wifi is unstable. Installed by default is ath9k. This is how to replace this unstable driver by madwifi.

1)

nano /etc/modprobe.d/blacklist
blacklist ath9k
blacklist mac80211
blacklist cfg80211

2)

apt-get install linux-headers-generic (or rt in my case)
svn checkout http://svn.madwifi-project.org/madwifi/trunk madwifi
cd svn/scripts
sh madwifi-unload
sh find-madwifi-modules.sh
cd ..
make
make install

3) reboot and enjoy

applesmc and pommed

nano /etc/modules
applesmc
modprobe applesmc

apt-get install pommed
nano /etc/pommed.conf
/etc/init.d/pommed restart
