This card, using the AR2413 chipset, is working as of 2008-12-30 using madwifi-hal-0.10.5.6 on an Acer Aspire 5040 running Linux Mint 6

To get it working, I did this:

• If you are using Ubuntu or an Ubuntu-based distro such as Linux Mint:
  • sudo nano /etc/default/linux-restricted-modules-common
  • add ath_hal between the quotes, save and exit (ctrl-o, ctrl-x)
• If acer-wmi is not installed, install it, then set your wireless switch on with the following command:
  • sudo echo 1 > /sys/devices/platform/acer-wmi/wireless
• Check if you already have madwifi installed
  • Run the following two commands for all athX and wifiX interfaces you see when you run ifconfig
  • ifconfig athX down
  • ifconfig wifiX down
• Next, grab the 0.10 sources and install everything you will need to compile them
  • sudo apt-get install build-essential linux-headers-$(uname -r) perl subversion
  • cd ~
  • svn checkout http://madwifi-project.org/svn/madwifi/branches/madwifi-hal-0.10.5.6 madwifi-hal-0.10.5.6
• Now you need to unload any previous versions of madwifi (0.9.4 is installed standard in many distros)
  • cd ./madwifi-hal-0.10.5.6/scripts
  • sudo ./madwifi-unload
  • sudo ./find-madwifi-modules.sh $(uname -r)
• And now you just need to compile and install it
  • cd ..
  • make
  • sudo make install
  • sudo modprobe ath_hal
  • sudo modprobe ath_pci
  • sudo modprobe wlan
• You should now be able to scan for networks and connect!
