Windows 7: 7 x64 Ultimate will not Wake-on-LAN

I am trying to set up my media server PC to be completely controlled from my Android phone. However, I am unable to get WoL working. I have enabled WoL from BIOS and the network device settings, but am still unable to wake the computer from sleep with a magic packet. I can wake the computer from sleep with other devices (ie: my USB keyboard).

I have the latest update for my BIOS, as well as the latest drivers for the onboard Ethernet adapter. I have enabled the option to allow PCIe devices to wake the computer, and have enabled the options on my onboard Ethernet adapter to "Wake on Magic Packet." Under Power Management, have "Allow the computer to turn off this device to save power," "Allow this device to wake the computer," and "Only allow a magic packet to wake the computer" checked. I have also tried unchecking "Allow the computer to turn off this device to save power," which also greys out the other two options, and that does not work either.

"wolsniffer" shows that the magic packet is being received when the computer is powered on, and I have tried enabling and disabling "Hybrid Sleep" mode because I have seen that suggested as a possible issue for Windows 7 WoL. Any suggestions on how to correct this issue would be much appreciated.

The computer:
Windows 7 Ultimate x64
Asus P7P55D mobo
Intel i5 750
GeForce 210
4GB RAM (unsure of speed)

When you receive the 'magic packet' on your machine when its powered on are you sending from your android device?

Have you tried to send/receive a 'magic packet' from another device apart from an android device?

Magic packets from other devices do not wake it either. Disabling the "Only allow a magic packet to wake this computer" makes it wake up from magic packets and any other LAN requests. At least it works now, I guess, but I would prefer if I could control what could wake the computer so I know it isn't waking up by itself.
