How to stop wifi blinking when running Ubuntu on Thinkpad

I’m running Ubuntu 12.04 on my Thinkpad x201. Out of the box, the wifi led indicator just below the screen blinks whenever there is any wifi activity.

It gets very annoying, so here is how you can turn it off

From your shell, type

    sudo nano /etc/modprobe.d/wlan.conf

Add the following line to the file

    options iwlwifi led_mode=1

Save the file, and exit nano.

If you’re impatient, you can type the following commands at the shell prompt for immediate gratification

    sudo modprobe -r iwlwifi
    sudo modprobe iwlwifi 

Or you can reboot your computer for the settings to take effect.
