Whith which cron command can I schedule the guest wifi to start/stop?

$ uci show wireless
wireless.wifinet2=wifi-iface
wireless.wifinet2.device='radio0'
wireless.wifinet2.mode='ap'
wireless.wifinet2.ssid='CG24'

Thank you!

Seen the wifischedule package ?

Yes, but can't I do it without the package, just with a Scheduled cron job? Thank you!

Thank you!
But I don't want the whole wifi to start, only guest wifi.
This seems to work:

* * * * * uci set wireless.wifinet2.disabled='1'; uci commit wireless; wifi
