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

Squeeze

See supported devices (squeeze) for device support available in this release.

  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-iwlwifi and wireless-tools packages:

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

    # modprobe -r iwlagn ; modprobe iwlagn
  4. Verify your device has an available interface:

    # iwconfig
  5. Configure your wireless interface as appropriate.

Wheezy

See supported devices (wheezy) for current device support in the testing distribution.

  1. 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
  2. Update the list of available packages and install the firmware-iwlwifi and wireless-tools packages:

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

    # modprobe -r iwlwifi ; modprobe iwlwifi
  4. Verify your device has an available interface:

    # iwconfig
  5. Configure your wireless interface as appropriate.

Supported Devices
