===== Author(s) =====

===== Introduction =====
This guide will help you configure the [[http://madwifi.org|Madwifi]] module for many Atheros based wireless controllers under Fedora 9.
===== Notes =====
We will be using 'nano' as our text editor of choice but you can use whatever you wish.
===== Prerequisites =====
You should run a full update for your installation of Fedora to ensure you have all the latest packages installed.

You should ensure the Madwifi module supports your particular card. [[http://madwifi.org/wiki/Compatibility|Here is a list]] of compatible cards. If you are not sure which card you have in your system you can use our [[Linux Wireless Chipset Detector]].
===== Installing the latest stable Madwifi module =====
We will be using the [[http://www.atrpms.net|ATrpms]] repository.


**1.** Load up a terminal window if you are in the graphic interface.

**2.** Switch to the root user by entering the command "su -" (without the quotes) and typing in your root password

**3.** Edit the file /etc/yum.conf. Using nano we type the command "nano -w /etc/yum.conf"

**4.** If you have already configured yum to use the ATrpms repository then append "*madwifi* *mac80211*" to the end of the "includepkgs" line and skip the next 3 steps. Otherwise continue on.

**5.** Add the following to the bottom of this file:
<code>[atrpms]
name=Fedora $releasever - $basearch - ATrpms
baseurl=http://dl.atrpms.net/f$releasever-$basearch/atrpms/stable
gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms
gpgcheck=1
enabled=1
exclude=*kmdl*i586*
includepkgs=*madwifi* *mac80211*</code>

**6.** Save the file. In nano you press Ctrl-X, answer yes to the "Save modified buffer" question and then press enter on the file name to write.

**7.** If you have not previously setup ATrpms execute the following command:
<code>rpm --import http://ATrpms.net/RPM-GPG-KEY.atrpms</code>

**8.** Now execute the following command:
<code>yum install madwifi</code>

**9.** Reboot your system and you will be using the Madwifi module.
