Have you ever tried to turn on your PC remotely using Local Area Network (LAN) or WAN connection? It is very useful when you are away from your PC and want to access it. Or you just want to show off to your friends or colleagues. After turning ON your PC, you can access files stored on it using TeamViewer or make your Computer a Web Server to access your files remotely. In this article I am going to explain, how to setup your computer to wake on LAN or WAN using WOL(Wake on Lan) utility. For that we have to make some changes to BIOS, and Device Manager. Now, Let’s start:
1. Setup the BIOS
To wake the computer on LAN/WAN, we have to make some changes to the BIOS settings of your computer. For making changes to BIOS settings, you can go to BIOS Screen by pressing DELETE or any other specified key to enter BIOS Setting.
Now goto Power tab of your computer’s BIOS settings and click on Automatic Power ON. This option may appear different depending on the type of the Motherboard of your PC, use your intelligence to find the right option.
Under Automatic Power ON menu, you will see options to enable Wake On LAN. Goto Wake Up On LAN and press Enter and Select Enabled.
We have made necessary changes to the BIOS settings. We have to save these settings before exiting. Goto Exit tab and select Save Changes And Exit. When prompted for confirmation select Yes.
Above settings could be different for you depending on your motherboard brand, use your intelligence to find the right setting.
2. After setting up BIOS, we need to make some changes in Computer Management also.
As we have already made changes to the BIOS settings in previous step, now it is time to make changes to Computer Management. This step is necessary to Wake your computer via LAN. Right-click Computer (or My Computer or This PC) icon on desktop and select Manage option. Computer Management will open.
In Computer Management, on the left panel, click on “Device Manager“. This will open Device Manager, double-click on Network Adapters. It will show you the Network adapters attached to your PC.
Double-click on your Network Adapter, it will show you it’s Properties. In Properties window, goto Advanced tab. If you don’t know which one is your adapter, check in your connection Properties.
Here we need to change two things.
1) Enable Shutdown Wake Up (This will help Over LAN).
2) Enable Wake on Magic Packet (This will help Over WAN).
3. Now your computer is ready to Power On over the Network.
Remeber: You have to keep IP Address and MAC address of the target computer ready before you try to turn it ON.
Enjoy! Now you can turn on your PC via LAN or WAN and Access your computer from anywhere. To turn ON your PC via WAN, you have to forward a port in your router i.e. UDP port 9 which is for Wake on Magic Packet port. After forwarding a port in your router, you have to use your WAN IP address in WOL utility to wake up your PC remotely. Check your Router’s manual to get help about forwarding a port. You can make your Computer a web server to access your files remotely or you can access your files using TeamViewer. Comment below if you face a problem! 🙂
