.SYNOPSIS
Enable Wake On LAN settings on NIC in Windows

.DESCRIPTION

IMPORTANT NOTE: I borrowed some from the WMI portions from here: http://justanothertechnicalblog.blogspot.com/2012/06/setting-power-management-options-on.html

This script will set the appropriate Windows-side 
Wake-On LAN settings on the NIC that is currently 
CONNECTED and has a match for the name "Ethernet" 
OR "Local Area Connection"

This script will check/set the following: 

1. "Allow the device to wake the computer" to CHECKED
2. "Only allow a magic packet to wake the computer" to CHECKED
3. "Energy Efficient Ethernet" to OFF
4. Fast Startup to DISABLED (Windows 8-10 only)

===============================================================
If your NIC is named something else, just change the "-match"
references on the "Get-NetAdapter" command below
===============================================================

NOTE: You will still need to make certain Wake On LAN is enabled
in the BIOS.
