Does anyone know where "Only allow a magic packet to wake this computer" setting has moved to in 2016-core?

This 2016-core server can be kept awake by continuous pings or if I let it suspend it can be woken by a Magic Packet but does not wake on ping or any other network packets.

On Server 2012 device manager for the NIC there are three check-boxes under the Power Management tab:

1).    "Allow the computer to turm off this device to save power"
2).    "Allow this device to wake the computer"
3).        "Only allow a magic packet to wake this computer"

I have identified that these are stored in the registry hive: HKLM\System\CCS\Control\Class{4D36e972-E325-11CE-BFC1...}\nnnn\PnPCapabilities (DWord)

Where:

24 - 1=off, 2=off, 3=off
16 - 1=on, 2=off, 3=off
0 - 1=on, 2=on, 3=off
256 - 1=on, 2=on, 3=on

I suspect that this setting is enabled by default, how do I disable it in Server-core?

Set-NetAdapterAdvancedProperty -Name "Ethernet" -DisplayName "Wake on magic packet" -DisplayValue "Disabled"  

To see the current values:

Get-NetAdapterAdvancedProperty -Name "*"

  • Unfortunately not, this does not seem to change the: "Only allow a magic packet to wake this computer" device manager behaviour. Have tried this out on a 2012 (server with a GUI) install and found that it relates instead to the NIC Advanced tab setting rather than the Power Management tab setting. – NickC Jan 13 at 15:20
  • Is it possible that Server-Core simply doesn't support Power Saving at all? – NickC Jan 13 at 15:37
