I have a case and I know someone else with a case open with Intel support for the WOL/Sleep problem on the DP55KG/DP55WG. They keep lying and saying that it works for them. Keep trying to escalate it...
I am confused though, are you saying that S3 (sleep) is working for you? It will idle to sleep (not you manually doing it)? If so please post what is connected to the machine (USB, eSata, etc.) and what OS (Win7 x32 or x64, etc.). Also did you turn any features off in the bios like the bluetooth or sata, etc...
Yes, S3 works for me, I just checked again. The PC enters sleep according to the energy options on its own. It just doesn't wake up from it without keyboard activity, no matter how I configure the BIOS or the network card options. And that's bad because I frequently need access to my PC while I'm on the road and don't like to have it running idle for hours wasting energy.
I'm using Windows 7 x64, fully updated, latest drivers everywhere. There's a lot of stuff connected to my PC: USB printer (Canon), USB Wacom tablet, USB MS keyboard and mouse, USB Steinberg Hardware Key, USB Logitech Quickcam, USB Logitech Gamepad, 2 eSATA drives, 4 internal SATA HDs (AHCI-mode) + SATA DVD-ROM, 2 DVI monitors...
I didn't do anything out of the ordinary in the BIOS - no features deactivated, only setting I changed was using a specific RAM-profile for my memory modules to get the memory bus to 1600 MHz.
The DP55KG is probably the best mainboard I ever had in terms of stability, compatibility and speed, if it were not for the WOL issue.
Has anyone found a solution to this problem?
I have 30 brand new (6 months) intel dh55tc MBs that we had WOL working perfectly.
We upgraded the bios to latest version becasue the network cards were randomly dissabling themselves in windows (XP and Win7)
After the upgrade WOL no longer works....
Trying to find a way to contact Intel to get support on this is impossible
Install the LAN driver version 14.6 ... (Downgrade)
