Atheros AR9170 devices (ar9170usb)

This page describes how to enable support for WiFi devices based on the Atheros AR9170 chipset on Debian systems.

{i} Wheezy users, see carl9170 for device support.

ar9170usb is a driver for the Atheros AR9170 ("otus") 802.11 draft-n USB wireless LAN chipset, introduced in Linux 2.6.30. Supported devices are listed at the end of this page.

{i} Atheros AR9271/AR7010-based USB devices are supported by ath9k_htc. Atheros 802.11n PCI devices are supported by ath9k.

Installation

Squeeze

Firmware is required to be installed for device operation.

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

    # Debian Squeeze/6.0
    deb http://ftp.us.debian.org/debian squeeze main contrib non-free
  2. Update the list of available packages and install the firmware-atheros package:

    # aptitude update && aptitude install firmware-atheros
  3. Connect the device to your system. The ar9170usb kernel module is automatically loaded for supported devices.

  4. Configure your wireless interface as appropriate.

Wheezy

The ar9170usb driver was removed at Linux 3.0.1 See carl9170 for device support.

Troubleshooting

  • Examine the kernel ring buffer (dmesg(1)) to verify required firmware files are being loaded by the driver:

    [ 7032.396963] usb 2-1: firmware: requesting ar9170.fw
    [ 7032.427345] usb 2-1: ar9170.fw firmware file not found, trying old firmware...
    [ 7032.442582] usb 2-1: firmware: requesting ar9170-1.fw
    [ 7032.495148] usb 2-1: file with init values not found.
    [ 7032.514607] ar9170usb: probe of 2-1:1.0 failed with error -2
    • If requested firmware is not available, no wireless interface will be created.
    • After firmware is installed, reconnect the device or reload the module (modprobe -r ar9170usb ; modprobe ar9170usb).

  • Use of the Qwest/Actiontec 802AIN device (USB ID 1668:1200) requires the usb-modeswitch package to be installed.2
