Windows 8: Resetting a wireless adapter when a PC wakes up

As of 1/5/2015 the Surface Pro 3 still has wireless problems when waking up from sleep.
One way to address this is by resetting the wireless adapter when the PC wakes up.
The following process is based on capturing the wake up event and then running a script to reset the wireless adapter when this event occurs.

If you have not already done so, setup up powershell to execute scripts along with the already set interactive commands.

Prepare your powershell environment
1. Start powershell as administrator
2. enter: set-executionpolicy RemoteSigned
3. When prompted, select y and press enter to accept the policy change
