All my machines running identical Windows 10 setups wake on lan access. This means, I can send SMB, HTTP of RDP requests and they wake up. Then, this one Gigabyte board, only wakes on a WOL magic packet.
I cant imagine Intel screwed up their i211 nic. I doubt Gigabyte did the same (though this is an Aurus board and the BIOS leaves much to be desired).
What could it be?
