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 chipsets, using the ath9k driver on Debian systems.
Contents
ath9k is a driver supporting Atheros 802.11n PCI/PCI-E chipsets, included in the mainline Linux kernel since version 2.6.27.
It does not require a binary HAL (hardware abstraction layer) and no firmware is required to be loaded from userspace. Supported devices are listed at the end of this page.
Atheros 802.11n USB devices are supported by the ath9k_htc and ar9170usb / carl9170 drivers.
Atheros 802.11a/bg PCI/PCI-E devices are supported by the ath5k driver.
Installation
Install the wireless-tools package:
# aptitude install wireless-tools
- If not already performed, physically connect the device to your system.
The ath9k kernel module is automatically loaded for supported devices. Verify your device has an available interface:
# iwconfig
Configure your wireless interface as appropriate.
