WOL cant be activated
i had set up my pc to be able to remotely power up via WOL. however it works few mins after the device has shut down. i tried by using mobile data on my phone to simulate that i am not connected by wifi and yet able to power up.
however about 5 - 10 mins later when i ran the simulation the device couldn't be power up. and i checjed the settings here and there, long story short, realised that the device ip & mac address details do not appear in my DHCP server and i am guessing thats the reason why I couldn't power up my device.
likewise, when the address of the device are in dhcp server, i could power up it through WOL. so i like to ask if there is a permanent good way to do so.
also, why does a network company doesn't has an in-function WOL feature in their router apps, unlike ASUS. performing WOL back then was a breeze with ASUS.
in summary what i did:
ip & mac binding
ip address reservation
created and bind DDNS with status showing operation
simulate and managed to power on through WOL if device was previously turned on and shutdown within a short time frame (5 - 10 mins), after that mins passed, when device is not in dhcp server list then i cannot do WOL anymore.
did i get my settings wrong?
