Controlling the status LED

If you find the flashing wireless LED annoying, you can change its behavior so it will be on steady whenever the radio is powered on, and off when the radio is off. Create a file /etc/modprobe.d/iwlcore.conf with the line "options iwlcore led_mode=1" to set the LED on steady, or you can set led_mode=0 to have it flash whenever there is wireless activity (default). To make changes take effect immediately do "rmmod iwlagn ; rmmod iwlcore ; modprobe iwlagn"

Installation under Debian stable 6.0.6 („Squeeze“)

Running Debian stable 6.0.6 („Squeeze“) WiFi will not work after a fresh installation. Add a non-free source to /etc/apt/sources.list and run

apt-get update
apt-get install firmware-iwlwifi

This should also work for Debian's testing and unstable branch.

Kernel 2.6.27-rc5 (as a patched kernel 2.6.26)

  • download linux kernel 2.6.26
  • download linux kernel prepatch 2.6.27-rc5


  • make menuconfig

Device Drivers => Network device surppot => wireless LAN

  • make && make modules_install
  • cp arch/i386/boot/bzImage /boot/kernel-2.6.27-rc5
  • install wpa_supplicant
  • now enjoy your new wireless card :)

alternative if you want to use your stock < 2.6.27 Kernel


Debian with kernel 2.6.28

  • Get the Microcode

Download the iwlifi-5000 tarball with microcode (firmware) from IntelLinuxWireless

  • Extract the contents of the tarball:
tar xzf iwlwifi-5000-ucode-5.4.A.11.tar.gz

(filename could be different)

  • Copy the microcode file to /lib/firmware:
sudo cp ./iwlwifi-5000-ucode-5.4.A.11/iwlwifi-5000-1.ucode /lib/firmware

(the directory name extracted from tarball could be different as well)

  • Add repository

Add the following line to your /etc/apt/sources.list:

deb trunk main
  • Update your local package index:
sudo apt-get update
  • Install linux-image-2.6.28-1-686
sudo apt-get install linux-image-2.6.28-1-686

If you need the headers

Finally, if you need linux-headers-2.6.28-1-686, for instance to install propietary ATI drivers, then you'll have to satisfy the dependency of linux-kbuild-2.6.28. This package is not in the repositories, but you can build it yourself following the instructions at:

See section "How to build linux-kbuild-2.6 yourself"
