Scheduling on/off wifi

Installing and Using OpenWrt

I'm using the following small snippet on my boxes, maybe others find this useful, too:

#!/bin/sh
#
# ap-toggle script
# written by Dirk Brenken (dev@brenken.org)
# usage:
#   ap-toggle.sh on <radio>  => switch the AP on all radios "on", you can limit this with the optional <radio>-parm
#   ap-toggle.sh off <radio> => switch the AP on all radios "off", you can limit this with the optional <radio>-parm
# reference this script in /etc/crontabs/root and restart cron service afterwards, e.g.:
#   0 00 * * *    /usr/bin/ap-toggle.sh off
#   0 06 * * *    /usr/bin/ap-toggle.sh on

        fi
