How to Enable Wake on LAN: Turn on Your PC Remotely Imagine being miles away from home and realizing a crucial file is trapped on your turned-off desktop. Instead of driving back, you can tap a button on your phone and watch your computer spring to life. This is the power of Wake on LAN (WoL), a networking protocol built into modern motherboards that allows you to turn on a PC remotely using a data packet sent over your local network.
Setting up Wake on LAN requires configuring your hardware, your operating system, and choosing an app to send the signal. Follow this step-by-step guide to get it up and running. Prerequisites Before You Start
Wired Ethernet Connection: WoL requires your network card to constantly listen for incoming signals. While “Wake on Wireless LAN” exists, it is notoriously unreliable and often only works from sleep mode rather than a full shutdown. For the best results, use a physical Ethernet cable plugged into your router.
Power Delivery: Your computer must remain plugged into a live power outlet. If you suffer a complete power blackout, WoL usually will not work until the PC is manually turned back on once. Step 1: Enable WoL in Your Motherboard BIOS/UEFI
Before Windows loads, your motherboard hardware must be configured to keep the Ethernet port powered on to listen for commands. Wake On Lan – Remotely Turn On Your Computer
