Official support for the AR5008/AR5418 chipset is expected in the upcoming 0.9.40 release of the madwifi-hal however, in the meantime, there is pre-release support with which some have found some success. In order to take advantage of the latest version of the code, you can either download the nightly snapshot, or use subversion as described below:

  • make (if necessary) and change to a directory where you new directory
user@box:~/$ mkdir -p madwifi
user@box:~/$ cd madwifi
  • Fetch files using svn
user@box:~/madwifi$ svn co http://svn.madwifi.org/trunk
.
.
.
Checked out revision ####.
  • Now enter the directory and start compiling:
user@box:~/madwifi$ cd trunk/
user@box:~/madwifi/trunk$ make

. . .

  • With a little luck, you now have a properly compiled driver, ready for install. You'll probably be asked to enter the root password.
user@box:~/madwifi/trunk$ sudo make install
  • Now all that's missing is probing the module and we should be set.
user@box:~/madwifi/trunk$ sudo modprobe ath_pci
  • This should result in two new interfaces being created "wifi0" and "wlan0":
user@box:~/madwifi/trunk$ /sbin/ifconfig

It's wlan0 that you're after. Who knows what this wifi0 business is all about.
