Fortunately, the makers of Ethernet and Wi-Fi adapters have worked around these issues, and ensure that most of their products retain enough power to accept a WoL command in Windows, macOS, and plenty of Linux distributions. Windows 7 doesn't support it officially and if you have fast startup enabled in Windows 8 and 10, that can potentially cause problems, too.
When a computer is in a low-power state, it can be powered back up if the Ethernet adapter receives a "magic packet." This is a tiny block of data, broadcast across the whole network, that contains a 'wake up' instruction for a specific machine.įor a computer to react to this command, its network adapter and installed operating system must support WoL. One outcome of their combined efforts was an Ethernet standard called Wake-on-LAN (WoL). IBM and Intel collaborated on a project back in the mid-1990s to improve the way that computers on networks could be remotely managed.
