[Openwrt] Wifi Schedule via cron (No package required)

Reference: https://forum.openwrt.org/viewtopic.php?id=49797

1. Find out your wireless iface name.

root@openwrt ~ uci show wireless

[...] 

wireless.@wifi-iface[0]=wifi-iface
wireless.@wifi-iface[0].device='radio0'
wireless.@wifi-iface[0].network='lan'
wireless.@wifi-iface[0].mode='ap'

[...]

From the result, we know that the wireless iface is @wifi-iface[0].

2. Edit crontab to start schedule service.

root@openwrt ~ cat /etc/crontabs/root

30 0 * * *  uci set wireless.@wifi-iface[0].disabled=1 && uci commit wireless && wifi
30 6 * * *  uci set wireless.@wifi-iface[0].disabled=0 && uci commit wireless && wifi

3. if you are interested, you can use remote ssh command to turn on|off all your wifi in your home network. Write a script and loop through all your network router.
