#pragma section-numbers on ||<>|| ~+''This guide is only applicable for '''server''' installations of Ubuntu. If you are running a '''desktop''' installation of Ubuntu, try [[WifiDocs/Driver/Madwifi]] and the [[http://madwifi.org/wiki/|MadWifi wiki]] for more information.''+~ = Checking For Atheros Chipsets = First, verify that your wireless network adapter requires the madwifi device drivers. Issue the following command: {{{ sudo lspci | grep Atheros }}} If there is any output similar to that below, you should definitely install madwifi. {{{ 00:0e.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01) }}} If there is no output, try looking through [[http://madwifi.org/wiki/Compatibility]] to see if your network adapter is supported. = Installation = === Ubuntu 8.04 === The drivers are in the restricted modules package; also see the `madwifi-tools` package. {{{ sudo apt-get install linux-restricted-modules madwifi-tools }}} === Ubuntu 7.10 === Navigate to [[http://madwifi.org/]] and download and extract the latest version of the madwifi drivers (0.9.4 at the time of this writing) {{{ wget http://internap.dl.sourceforge.net/sourceforge/madwifi/madwifi-0.9.4.tar.gz tar -xvzf madwifi-0.9.4.tar.gz cd madwifi-0.9.4 }}} Download the necessary tools, compile and install the module {{{ sudo apt-get install build-essential linux-headers-server make sudo make install }}} == Setting Master Mode == __'''NOTE'''__: If you are plan on using this wireless network adapter in "master" mode (i. e. for the purposes of setting up a wireless router), create the file `/etc/modprobe.d/madwifi` and add the following to it: {{{ options ath_pci autocreate=ap }}} This will tell madwifi to set your wireless device (ath0) to master mode. Finally, load the module {{{ sudo modprobe ath_pci }}} = Sources = 1. [[http://madwifi.org/wiki/UserDocs/FirstTimeHowTo|MadWifi 'First Time User' HOWTO]] 1.
