Being an avid user of the Wake-On-Lan feature in Logmein and various utilities, I was not thrilled when I found that none were working in Windows 8 RTM version.  I finally isolated the issue to a new feature in Windows 8 that allows for quicker boot times.  Below is how I got it to work.  Note: Disabling this feature does slow the boot times of some systems however in my systems using SSD’s, I could not discern much difference between it on or off.

  • From the Windows “Start” menu, type”power options”, click on “Settings, and click on “Change what the Power Buttons Do”.

  • Uncheck the option “Turn On Fast Startup”

Once you do that, your Wake-On-Lan should now work.  I verified this using Logmein and it worked great.  You will have to test your particular utilities to make sure that this corrects the issue.
