wake-on-lan

I have the following set up:

Gigabyte Z77X-UD5H
Wake On Lan Enabled

Asus N66U
Port Forwarding
Static IP assigned to my computer

Windows 7
Advanced Power Management - PCI Express - Off
Intel 82579V - All options under Power Management checked

I'm trying to set this up for Wake on Wan capabilities. If I shut down my computer and immediately try to Wake on Wan (and Lan) it works and starts up. While the computer is on, I've used a few WOL specific packet sniffers and the packet comes through on the correct port. After any period of time over a few minutes, waking on Wan or Lan won't work. The back "activity" light is blinking on my ethernet port on my computer, as well as on the router, so I would assume the network card is on and able to receive a signal.

Any ideas? Suggestions? What can I do to troubleshoot the problem?
