Atheros 802.11a/bg PCI/PCI-E devices (ath5k)

This page describes how to enable support for WiFi devices based on Atheros 802.11a/bg PCI/PCI-E chips, using the ath5k driver on Debian systems.

ath5k is a Linux kernel driver supporting Atheros 802.11a/bg PCI/PCI-E chips, introduced at Linux 2.6.25. Supported devices are listed at the end of this page.

Unlike the MadWifi driver, ath5k does not require a binary HAL (hardware abstraction layer). No firmware is required to be loaded from userspace.

{i} Atheros 802.11a/bg USB devices are supported by the zd1211rw driver.

{i} Atheros 802.11n PCI/PCI-E devices are supported by the ath9k driver.

Installation

The ath5k driver is present in Debian Linux kernel images since version 2.6.24.

Switching from MadWifi to ath5k

This section can be skipped if MadWifi was not previously used.

  • madwifi-tools (version 1:0.9.4~rc2+dfsg-1 and later) installs the /etc/modprobe.d/madwifi file, which blacklists the ath5k driver.

    • Purge the madwifi-tools package (aptitude purge madwifi-tools) and run update-initramfs -u -k all to also remove this blacklist from initramfs.

  • Amend /etc/udev/rules.d/70-persistent-net.rules and change 'ath0' to 'wlan0'.

  • Amend /etc/network/interfaces, changing all references of 'ath0' to 'wlan0'.

  • Restart your system.
  • Verify that wireless networking is functional.

    • If you can connect but not send/receive anything, you might need to adjust your firewall configuration. For example, if you have configured your firewall using shorewall, find and replace all occurrences of 'ath0' with 'wlan0' in files within /etc/shorewall.

    • squeeze/hostapd users: the ath5k driver implements access point functionality as of Debian 6.0 "Squeeze". You are required to amend any existing hostapd configuration (driver=madwifi → driver=nl80211). See the hostapd Linux documentation page for more information.

Configuration

  1. Connect the device to your system. The ath5k kernel module is automatically loaded for supported devices.

  2. Configure your wireless interface as appropriate.

Supported Devices

The page HowToIdentifyADevice/PCI explains how to identify a PCI device.

The following list is based on the alias fields of modinfo ath5k in Debian 3.2.0 (3.2.41-2) kernel images.
