Turning ON/OFF wireless on ASUS K52j

Here’s a quick fix to enable/disable wireless using Fn+F2 on Slackware Linux on ASUS K52j and also the LED to indicate the status of the wireless. First you need to create this file: /etc/acpi/events/etc/acpi/events/asus-wireless-switch This file will contain the hotkey and the path to the script which is setting the wireless ON/OFF. The /etc/acpi/events/etc/acpi/events/asus-wireless-switch content will be:

#Enable the Fn-F2 button to turn on/off wireless
event=hotkey ATKD 0000005d

Then create another one: /etc/acpi/asus-wireless-switch.sh

With this script in it:

WLANSTATUS=`cat /sys/class/ieee80211/phy0/rfkill*/state`

test -z $WLANSTATUS && exit 1

if [ $WLANSTATUS = 0 ]; then
        echo 0 > /sys/devices/platform/asus_laptop/wlan
        echo 1 > /sys/class/ieee80211/phy0/rfkill*/state
elif [ $WLANSTATUS = 1 ]; then
        echo 1 > /sys/devices/platform/asus_laptop/wlan
        echo 0 > /sys/class/ieee80211/phy0/rfkill*/state
