You need to add following configure file

This will open an empty file, copy the code below into it:

#!/bin/sh 
/sbin/iwconfig wlan0 power off
 

Save the file and remember to:

sudo chmod u+x wifi_pwr_off

and restart.

Please note that instead of wlan0 it can be wlan1 etc for you. You can see interfaces with ifconfig
