=== Squeeze ===

 1. Add the [[Backports|Debian Backports]] repository to {{{/etc/apt/sources.list}}}, also including the "non-free" component. For example: {{{

deb http://backports.debian.org/debian-backports squeeze-backports main contrib non-free
}}}
 1. Update the list of available packages: {{{
aptitude update
}}}
 1. Install a Linux 3.2.0 kernel image appropriate for your system, along with the DebianPkg:squeeze-backports/firmware-atheros package. For example: {{{
aptitude -t squeeze-backports install linux-image-$(uname -r|sed 's,[^-]*-[^-]*-,,') firmware-atheros
}}}
 1. Restart your system and boot with the newly installed Linux kernel.

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.

ath9k_htc is a Linux kernel driver supporting Atheros 802.11n USB chipsets, introduced at Linux 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

Firmware is required for device operation. Two options are available:

{i} Atheros AR9170-based 802.11 draft-n devices are supported by ar9170usb.

Installation (free firmware)

  1. Install required packages: 

    $ su
# apt-get install build-essential cmake git m4 && exit

  2. Clone the 1.3 branch: 

    $ git clone -b 1.3 https://github.com/qca/open-ath9k-htc-firmware.git
$ cd open-ath9k-htc-firmware

  3. Fix issue 6 which causes the build process to fail: 

    $ mkdir target_firmware/magpie_fw_dev/build/utility/bin

  4. Build the toolchain: 

    $ make toolchain

  5. Build the firmware: 

    $ ./build

  6. Install the firmware: 

    $ su
# mkdir /usr/local/lib/firmware && cp *.fw /usr/local/lib/firmware/

  7. Connect the device to your system. The ath9k_htc kernel module is automatically loaded for supported devices.

  8. Configure your wireless interface as appropriate.

<<Anchor(fw-nonfree>>

Installation (non-free firmware)

  1. Add a "non-free" component to /etc/apt/sources.list, for example: 

    # Debian 7.0 "Wheezy"
deb http://http.debian.net/debian/ wheezy main contrib non-free

  2. Update the list of available packages and install the firmware-atheros package: 

    # apt-get update && apt-get install firmware-atheros

  3. Connect the device to your system. The ath9k_htc kernel module is automatically loaded for supported devices.

  4. Configure your wireless interface as appropriate.
