Wake-on-LAN (WOL) is a great feature of PCs which allows you to wake them up from sleep or shutdown over your local area network or over the Internet. It is like a remote power on button. If your hardware has WOL support, you can power on the computer remotely using any of the dozens of freeware tools available on the web to initiate the wake up event. In this article, I will cover the basic steps which are required to configure WOL under Windows 8 and Windows 8.1.
- First, you must enter your BIOS to find and enable the 'Wake on LAN' feature if you have some integrated Ethernet network card. For my Phoenix BIOS, it is located at Advanced -> Wake Up Events -> Wake up on LAN and also requires the 'Deep Sleep' option to be disabled. This option in the BIOS varies from PC to PC, so refer to your hardware manual for your motherboard.
- Boot into Windows 8 and press Win + X keys together to bring up the Power Users menu:
Click the Device Manager item.
- In Device Manager, locate you network adapter and double click it. It will display the network adapter's properties.
- Switch to the Advanced tab and scroll down in the settings to locate the network adapter's option called Wake on Magic Packet. Set it to 'Enabled':
- Now go to the Power Management tab, and check the settings there. It should be something like this:
- Install the Simple TCPIP Services feature: press Win + R shortcut on your keyboard and type the following command in the Run dialog:
- Reboot your PC.
- Open UDP port 9 in Windows Firewall - to do this, go to Control Panel\All Control Panel Items\Windows Firewall, click 'Advanced Settings' on the left, and create a new Inbound Rule to open the required port.
That's it. Now you need to write down the MAC address of your network adapter somewhere. To see it, press Win + R shortcut on the keyboard and type msinfo32 into the Run box. The System Information application will be displayed on the screen. Navigate to the Components -> Network -> Adapter and look for the MAC address line of your adapter:
Tip: Select the line on the right and press Ctrl+C on the keyboard. It will copy the MAC address to the clipboard in the following format:
MAC Address ?D4:3D:38:A6:A1:80?
On another PC, download this little freeware app called WolCmd. It is my recommended command line utility which must be used according to the following syntax:
wolcmd [mac address] [ip address] [subnet mask] [port number]
So in my case, to wake up my own PC, I have to run it as follows:
wolcmd D43D38A6A180 192.168.0.100 255.255.255.0 9
While typing the syntax, just delete the ":" char from the MAC address and use your actual network parameters.
In case you don't know what is subnet mask and your IP address, the Network -> Adapter section of System Information also shows that. Look for the values: IP Address and IP Subnet. You can copy them using Ctrl+C.
That's it. Now you can create a shortcut to run wolcmd and wake up your PC via the network with one click.
