Yet another sleep issue - Network Adapter Related

[EvilNIC]

Hello, hopefully someone can offer some assistance on an issue I'm having with getting windows 8.1 to sleep.

I have narrowed my sleep issues down to the network adapter (Intel(R) 82566DC Gigabit Network Connection) as whenever I disable the device in device manager the PC sleeps, whenever it's enabled it doesn't.

Now I've got that far I haven't any idea what the network adapter is doing to keep the system awake. Powercfg -requests shows nothing, and power management is set to allow windows to turn off the adapter to save power. I'm really not sure what its doing to prevent sleep, media streaming is off (even so, allow computer to sleep while sharing media is enabled), I'm not in a homegroup and IPV6 is disabled.

Does anyone have any other ideas I could try?

Thank you for any assistance.

Hello NIC, and welcome to Eight Forums.

Do already have the Allow this device to wake the computer box unchecked in the network adapter's "Power Management" properties?

Hope this helps for now,

Hi Brink, Thanks for the welcome and reply.

The "allow device to wake computer" check-box is definitely unchecked.

As for the link, unfortunately I've gone through that before, no device is able to wake my PC except for the power button, making this more of a head scratcher...

Thanks for the assistance so far.
