Hi
WOL would be super handy from either the web portal or remote control app as a click to wake button.
Yes, it needs another system on the same network to function and setup on the target machine bios/network settings.
We can do it with remote access to another system, copy the mac from the portal (or have documented), then manually issue wol etc.
It works ok at least 90% of time, but many RMM’s have this built in.
