Intel Wireless WiFi Link, Wireless-N, Advanced-N, Ultimate-N devices

This page describes how to enable support for Intel 802.11n devices on Debian systems.

The iwlwifi module (iwlagn prior to Linux 3.2) is produced by the iwlwifi Linux kernel driver, which supports several Intel wireless LAN adapters:

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

{i} For support of Intel 3945ABG/BG and 4965AGN devices, see iwlegacy.

Installation

Debian 7 "Wheezy"

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

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

    # apt-get update && apt-get install firmware-iwlwifi
  3. As the iwlwifi module is automatically loaded for supported devices, reinsert this module to access installed firmware:

    # modprobe -r iwlwifi ; modprobe iwlwifi
  4. Configure your wireless interface as appropriate.

Debian 6.0 "Squeeze"

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

    # Debian 6.0 "Squeeze"
    deb http://http.debian.net/debian/ squeeze main contrib non-free
  2. Update the list of available packages and install the firmware-iwlwifi package:

    # apt-get update && apt-get install firmware-iwlwifi
  3. As the iwlagn module is automatically loaded for supported devices, reinsert this module to access installed firmware:

    # modprobe -r iwlagn ; modprobe iwlagn
  4. Configure your wireless interface as appropriate.

Supported Devices

The page HowToIdentifyADevice/PCI explains how to identify a PCI device.

The following list is based on the alias fields of modinfo iwlwifi in Debian 3.2.0 (3.2.46-1) kernel images.
