You’ll want to look around for something similar to power settings.If you do not see these options in your power settings, it could be in advanced, networking, or onboard devices. Once you’re in you’re in we’ll start changing some settings. In order to wake your machine up, we have to be sure that WoL features are turned on in the BIOS and that other features are disabled.Since I cannot test every single BIOS out there, I am going to use my machine as an example for the types of options you will need to enable or disable.Most of the options should be named similarly however where it is located in your BIOS will depend on your manufacturer.įirst, you’ll need to get into the BIOS of the machine, this is typically done by pressing a key at book like f2 or del but varies by machine. The client sends a special packet (sometimes referred to as a “magic packet”) and the remote machine will wake up either from a cold power state or from sleep.This is where it starts to get complicated because different hardware manufactures have implemented different controls in BIOS to enable or disable this, and to make even more complex operating systems like Windows, macOS, and Linux have also implemented their own way to wake the machine up when it’s sleeping or in a low powered state.I am just going to throw this out there, Wake on LAN is hard.Since there are many different combinations I will try to cover how to configure your machines wake up successfully regardless of hardware, operating system, and power state. Wake on LAN (WoL) is a networking standard that allows a computer to be turned on by sending a network packet. What is Wake on LAN and why is it so hard?Īfter releasing my video on the PiKVM I realized that there was so much confusion about Wake on LAN, and rightfully so, that I decided to put together this guide on how to configure Wake on LAN on any machine.
