Atmel at76c503, at76c505, at76c505a devices

This page describes how to enable support for WiFi devices based on Atmel at76x USB chipsets on Debian systems.

at76c50x-usb is a mac80211 port of the at76_usb driver, supporting 802.11b USB wireless LAN devices based on Atmel at76c503, at76c505 and at76c505a chipsets. It is part of the Linux kernel since version 2.6.30. Supported devices are listed at the end of this page.

Non-free firmware is required, which can be provided by installing the atmel-firmware package.

{i} For assistance with Atmel PCI or PCMCIA wireless devices, see the atmel_pci and atmel_cs pages respectively.


Firmware is required to be installed for device operation:

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

    # Debian 7 "Wheezy"
    deb wheezy main contrib non-free
  2. Update the list of available packages and install the atmel-firmware package:

    # apt-get update && apt-get install atmel-firmware
  3. Connect the device to your system. The at76c50x-usb kernel module is automatically loaded for supported devices.

  4. Configure your wireless interface as appropriate.
