Networking

Most laptops have a hardware LED light to indicate status of the wireless connection.  Many devices that use Intel wireless drivers default to a LED light that blinks with activity.  This can be annoying to some people.  You can use the following to change the mode of the blinking LED to something more to your liking.

Create a file in /etc/modprobe.d/ called wifi_intel.conf (name not really important) and put in the following:

options MODNAME led_mode=X

where X is one of the following Numbers

0=system default

1=On(RF On)/Off(RF Off)

2=blinking

3=Off

and the MODNAME is

iwlwifi for most modern intel cards

iwlegacy for many older intel cards

ipw2200 for Intel Prowireless chipsets (use led= instaed of led_mode= for ipw2200)

inxi -n will show you your different network interfaces and which driver they are using.  For instance, for Intel iwlwifi, your inxi -n output might look like this:

 Card-2: Intel Centrino Advanced-N + WiMAX 6250 [Kilmer Peak]
           driver: iwlwifi
           IF: wlan0 state: up mac: 00:23:15:7b:a8:14

EXAMPLE:  

iwlwifi driver

/etc/modprobe.d/wifi-intel.conf

options iwlwifi led_mode=1

will set the led to solid if wireless is on, off if wireless is off.
