I got the wake on LAN working for “Windows 7 sleep mode” which is power state S2 I guess. Unfortunately waking the system up from “Windows Power off” which is Power State S5 doesn’t work at all?
You have to uncheck on "power managment tab", “allow the computer to shut down this device to save power”. and make sure, the complete driver package of the LAN card is installed. Start the driver installation by autorun, setup, or install.
