  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.
