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 Linux kernel driver supports several Intel wireless LAN adapters:

Supported devices are listed at the end of this page. 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 8 "Jessie"

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

    # Debian 8 "Jessie"
    deb http://http.debian.net/debian/ jessie 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 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.

Troubleshooting

Slow WiFi problems when using Bluetooth

Some devices like the 6235 do include a Bluetooth device in the same card, which may lead into radio conflict. Newer devices (7200 and up) try to solve them intelligently, but it is not the case of older ones.

If your WiFi is slow when using Bluetooth, try adding the following to /etc/modprobe.d/iwlwifi.conf and reboot:

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 3.16 (3.16.7-ckt9-2) kernel images.
