I have been struggling for a while to identify why Wake On LAN is not working since I installed Windows 7 on my computer. It worked fine with Windows XP but after moving to windows 7, it never worked. After lot of testing and trying various things, I finally reached the solution.
So, here you go…
There is something called PME(Power Management Event) in Network connection properties which should be in enabled state to make your Windows 7 computer process the magic packets to wake up your computer.
To enable PME, follow the below steps.
- Go to Start -> Run -> Type “ncpa.cpl” and click OK
- This opens up the network connections available in the computer. Here identify the NIC on which your computer will receive magic packets and go the properties of it.
- Click on Configure and Switch to advanced tab and select “Enable PME” property list and change the value to “Enable”
- Click on OK to complete the configuration.
This will make your network connection to blip briefly. Once your network connection is back your computer is ready to process the WOL packets. Shutdown your computer and try sending magic packet again. It should work without any issues.
