/etc/rc.local   This works for me: #!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. sleep 20; iwconfig wlan0 power off exit 0 We will make some generic solution, but until then this should do.
