# Script to ensure wireless lan radio is ON or OFF #
# between user selected times #
# The radio ON/OFF operation will not be performed if the system #
# clock is not in sync with local time, unless so required #
# Remember router is set back to default time after a reboot #
# Schedule this script at required intervals #
