Windows 8.1/Server 2012 R2
Windows 8.1 and Server 2012 R2 come with a bunch of highly useful cmdlets for network adapter management. When you want to investigate Wi-Fi connectivity problems, for example, or try and find out why Wake-On-LAN won’t wake the machine, it may be interesting to review the adapter power management settings.
This is now a piece of cake:
PS> Get-NetAdapter

WiFi Intel(R) Wireless-N 7260 3 Up
PS> Get-NetAdapter -Name WiFi
Name InterfaceDescription ifIndex Status
---- -------------------- ------- -----
WiFi Intel(R) Wireless-N 7260 3 Up
Once you know the name of the adapter, ask for the power management settings:
PS> Get-NetAdapter -Name WiFi | Get-NetAdapterPowerManagement InterfaceDescription : Intel(R) Wireless-N 7260 Name : WiFi ArpOffload : Enabled NSOffload : Enabled RsnRekeyOffload : Enabled D0PacketCoalescing : Enabled SelectiveSuspend : Unsupported DeviceSleepOnDisconnect : Disabled WakeOnMagicPacket : Enabled WakeOnPattern : Enabled
Note that you need Administrator privileges to view power management settings, or else you get misleading error messages about a device not working properly.
