Disable flashing wifi led

If your laptop has a wifi led that keeps flashing even when connected to the network, it's possible to disable it.

First you have to find out what wifi driver you are using. It's most likely iwlwifi, or the previous version called iwlagn. Just do a "lsmod | grep iwlwifi" or "lsmod | grep iwlagn" to identify what driver you are currently using.

Then edit /etc/modprobe.d/iwlwifi.conf or iwlagn.conf, whatever suits you. If it doesn't exist, it's ok, just create it. Then add the following line:
options iwlwifi led_mode=1

Now, restart your computer, or simply just gain root privileges and do a:
modprobe -r iwlagn && options iwlwifi led_mode=1 && modprobe iwlagn
