My motherboard provides Wake On LAN feature as you mentioned. But, I don't know how to enable the feature. Can you tell me?
At first, please try to get into BIOS setup program. Then under Power Management section, please try to enable PME EVENT WAKE UP option and save the setting to exit the program. After reboot into Windows, please open Device Manager, then check the status of LAN controller and enable the device wake up option later.
