After 2 hours troubleshooting, I think what finally fixed it was there's actually another setting that needs to be turned on in the Bios for WOL to work. To save others the work, here's what I did to get everything working.
In the BIOS go to the Advanced Tab:
-Click ACPI Configuration
-Set PCIE Devices Power on to "Enabled".

As you will see from the description, this must be enabled to allow Wake On Lan to work, I don't understand why this wasn't enabled to begin with C'est La Vie.
Hope this helps others.


The PCIE Devices Power setting was exactly my problem, thanks!

That setting mentions WOL, but that's not much use if you don't think to look there in the first place. It would've been good if the WOL setting mentioned the PCIE power setting too.

Yes that should work :). I currently have wake on lan setup to wake my PC no matter where I am. If you have issues then here's my list of what to do:

1. Enable Wake On Lan in the Bios
2. Disable Fast Startup in Power Options
3. Install the correct LAN drivers from your MB's support page.
4. Open device manager and locate the LAN driver. Open it's properties, Under Power Management and Advanced, Enable the the options in the snips here

thanks!, this totally fixed it was the remaining issue. Does this mean I can plug in things to the USB 3 port without causing Wake-on-LAN to stop working?

Was there ever an answer or fix for this specific board on Windows 10. I have the exact same settings and still not working for me.

I just mentioned the FAQ link, because I was browsing the ASRock help to get it to work for me. Even though I'm running Linux, I noticed the Windows Wake On Lan topics.

I don't know hopw to get it to work under Windows.

My board is running as a network server running Linux. I'm not going to install Win10 on it, just to try. It works for me, also after shutdown. So I know the hardware is capable.

Are you sure you need this option:
Realtec driver - Power Management - Allow the computer to turn off this device to save power enabled

Won't this prevent the network card from getting power and being able to listen?
