Atheros 802.11n PCI/PCI-E devices (ath9k)

This page describes how to enable support for WiFi devices based on Atheros 802.11n PCI/PCI-E chips, using the ath9k driver on Debian systems.

ath9k is a Linux kernel driver supporting Atheros 802.11n PCI/PCI-E chips, introduced at Linux 2.6.27. Supported devices are listed at the end of this page.

It does not require a binary HAL (hardware abstraction layer) and no firmware is required to be loaded from userspace.

{i} Atheros 802.11n USB devices are supported by the ath9k_htc and carl9170 drivers.

{i} Atheros 802.11a/bg PCI/PCI-E devices are supported by the ath5k driver.


  1. Connect the device to your system. The ath9k kernel module is automatically loaded for supported devices.

  2. Configure your wireless interface as appropriate.
