Some Windows users are complaining that the Wake on Lan (WOL) function in Windows is not working properly on their computers. Wake On Lan is one of the most popular features for the network administrators that can wake up remote setups simply by passing a command from another computer on the network. If the WOL isn’t working on your computer, don’t worry. Just follow these detailed solutions on the remote computer to solve the issue quickly.
Fix 1 – Allow power usage in Sleep mode

Fix 6 – Make sure the AC power is plugged in
The Wake on Lan or WOL doesn’t work properly if the remote computer is running on battery power. AC power is a must requirement for the WOL to work properly.
WOL is not supported on Windows 10 remote devices which are shut down
Wake On Lan or WOL won’t work on a remote computer in a complete shutdown state (S5) if the remote computer is running on Windows 10. The actual reason behind this is because Windows 10 doesn’t allow any power to the network devices to keep them running even after the machine is shut down by the user, so, the network cards can’t be armed to receive any WOL commands from another system. Either you have to put the remote setup in Sleep mode (S3) or you have to disable the fast startup so that WOL can work properly.
Fix 7 – Edit the registry
You have to edit the registry manually to allow the WOL request to switch ON your computer.
1. Press the Windows key+R keys together.
2. In the Run panel, write down “regedit” and click on “OK“.
Registry Editor is one of the most sensitive locations on your computer. So, before operating in the registry, you must create a backup of the registry.

5. Set the value to “1“.
6. Then, click on “OK“.
7. Similarly, on the right-hand pane, try to identify the “PowerDownPll” value.
8. Then, double click on the “PowerDownPll” value to edit it.
9. Now, set the ‘Value:’ to “0“.
10. Then, click on “OK“.
Close the Registry Editor window.
Restart the computer. After that, shut down your system and try to use the WOL command to wake it up again.
Fix 8 – Add a new key to the registry
If the previous registry tweak doesn’t work out for you, try these steps.
1. Open the Registry Editor.
2. Then, go to the location where you have found the ‘S5WakeOnLAN‘ key on your computer. Usually, it is located in this location –
