Atheros AR9271, AR7010 devices (ath9k_htc)
This page describes how to enable support for WiFi devices based on Atheros AR9271 and AR7010 chipsets on Debian systems.
Contents
ath9k_htc is a driver supporting Atheros 802.11n USB chipsets, included in the mainline Linux kernel since version 2.6.35. Supported devices are listed at the end of this page.
AR7010-based devices (e.g. Netgear WNDA3200, TP-Link TL-WN821N v3) operate in USB mass storage mode by default. Since Linux 2.6.39, the driver sends the necessary command to enable wireless LAN operation.1
Non-free firmware is required, which can be provided by installing the firmware-atheros package.
Atheros AR9170-based 802.11 draft-n devices are supported by ar9170usb.
Installation
Squeeze
Add the Debian Backports repository to /etc/apt/sources.list, also including the "non-free" component. For example:
# Backported packages for Debian Squeeze/6.0 deb http://backports.debian.org/debian-backports squeeze-backports main contrib non-free
Update the list of available packages:
aptitude update
Install a Linux 3.2.0 kernel image appropriate for your system, along with the squeeze-backports/firmware-atheros package. For example:
aptitude -t squeeze-backports install linux-image-$(uname -r|sed 's,[^-]*-[^-]*-,,') firmware-atheros
- Restart your system and boot with the newly installed Linux kernel.
Connect the device to your system. The ath9k_htc kernel module is automatically loaded for supported devices.
Configure your wireless interface as appropriate.
Wheezy
Add a "non-free" component to /etc/apt/sources.list, for example:
# Debian Wheezy (testing) deb http://ftp.us.debian.org/debian wheezy main contrib non-free
Update the list of available packages and install the firmware-atheros package:
aptitude update && aptitude install firmware-atheros
Connect the device to your system. The ath9k_htc kernel module is automatically loaded for supported devices.
Configure your wireless interface as appropriate.
