Stop the blinking wireless LED in Linux

I’ve recently had some problems with the wireless LED of my laptop in Linux. I have a Intel WiFi Link 5100 but this also applies to other Intel WiFi cards.  The LED that indicates that my WiFi is enabled or not, was blinking every time the WiFi card transmitted or received data. This seems like some special feature Intel introduced but it is really very annoying! Luckily you can stop the blinking, but this depends on your kernel version so make sure to look into the right section. I’m posting solutions for Linux Mint (Debian), Ubuntu and Arch Linux but I think this will also work for other distros.

Kernel version lower than 3.2.0

Put this text

options iwlagn led_mode=1

in the following file (possibly you have to create the file):

  • Linux Mint (Debian) or Ubuntu: /etc/modprobe.d/iwlagn.conf
  • Arch Linux: /etc/modprobe.d/modprobe.conf

Now restart your system or reload the WiFi driver using:
sudo -i
modprobe -r iwlagn && modprobe iwlagn

If that doesn’t work, you can try putting the following in the same file:

options iwl_legacy led_mode=1

Kernel version greater or equal to 3.2.0

Put this text

options iwlwifi led_mode=1

in the following file (possibly you have to create the file):

  • Linux Mint (Debian) or Ubuntu: /etc/modprobe.d/wlan.conf
  • Arch Linux: /etc/modprobe.d/modprobe.conf

Now restart your system or reload the WiFi driver using:
sudo -i
modprobe -r iwlwifi && modprobe iwlwifi

If that doesn’t work, you can try putting the following in the same file:

options iwlegacy led_mode=1

This fixed stopped the blinking on my laptop and I hope it also works for you!

  7. Simply would not work on HP 6910p with Linux Mint 14, but I found a different fix:
    sudo echo none > /sys/class/net/wlan0/device/leds/phy0-led/trigger
    This stops the led 🙂
