MikroTik

Hello:
I'm looking for a script that allows me to wake up a PC every day at a certain time.
eth2 mac: xx xx xx xx xx wake up 7:00 every day

You mean the Wake on LAN feature? First test if the command does what you need it to do.
[normis@MikroTik] > tool/wol interface=bridge mac=

If yes, then add this command to the "on-event" field of "/system/scheduler" and set the time, when it should be run.

ROS7 style
/system/scheduler/add disabled=no interval=24h name=wol on-event="tool/wol mac=xx:xx:xx:xx:xx:xx interface=xxxx" start-time=07:00:00
