I'm trying to set the blink mode for iwlwifi on Debian 8.

I have created iwlwifi.conf in /etc/modprobe.d and added options iwlwifi led_mode=1, but this is not affecting the activity light.

The firmware is installed as part of firmware-iwlwifi/oldstable.

Any advice is appreciated.

The device in this instance is an iwl4965.

The correct way to disable the LED on this device is options iwlegacy led_mode=1

Hopefully, this will be useful for anybody trying to disable this activity on Debian 8 Jessie.


I have a iwl3945 and to get the LED to blink, I needed to create the file:


with content

options iwl3945 led_mode=1

After this, I needed to:

sudo -i
modprobe -r iwl3945 && modprobe iwl3945
