On my newly purchased H77-D3H, I can only get Wake-On-LAN to work when the computer has recently been turned on and booted into my installed OS (Win7 x64 SP1). If the power to the computer has been off for some time (e.g. overnight), WOL won't work. If I then turn the power to the computer back on, I won't get any flashing lights on the onboard NIC (Atheros AR8151) or a link light at the router end until the computer is turned on which I believe is causing the problem.
Is there a fix for this? My processor is a Core i3-2100T and I've updated the BIOS from F8 to F11 as well as trying ErP Support set to both Enabled or Disabled. Any help would be greatly appreciated!
