I've searched and searched, and tried all sorts of suggestions, but I can't seem to prevent Windows 7 from turning off my NIC when I shut down. Quick summary:
+ wake-on-lan is enabled in BIOS (Asus Rampage III Formula - I have both wake-on-lan from s5 and the two wake from PCI/PCIE options turned on)
+ wake-on-lan is enabled in network adapter
driver (onboard Intel 82567V-2 - wake on magic packet and wake on magic packet from power off both enabled)
+ network adapter
driver is up to date
+ have tested with machine running, and magic packets *are* getting through
When I turn the computer off with the power button while *not* in windows (for instance, during boot), everything works as it should: NIC light stays on, system wakes on magic packet.
However, when I shut down from within Windows 7, the NIC light goes out & system is unresponsive to magic packets.
I'm almost positive I had this working previously... but haven't used it in a long time. How can I force windows to leave the NIC powered when shutting down?
UPDATE: I've just confirmed that WOL from Sleep doesn't work for me under Windows 7 either. Again, the machine goes into the proper state, but the NIC light goes out.
