Powered-off computers with WOL will include network devices that can “listen” to incoming packets in a low-power mode when the system is turned off. The magic packet includes the MAC address of the target computer, the identification number built into each network interface card, or other Ethernet devices in the computer, so that it can be uniquely identified and addressed on the network. Wake On LAN (WOL) is implemented using specially designed frames called a magic packet, which is sent to all computers on the network, including the computer to be woken up.

If you want to fix problems with Wi-Fi, then it is recommended to go to the MiniTool website. If the computer being woken up is communicating via Wi-Fi, a supplementary standard called Wake on Wireless LAN (WoWLAN) must be used. Equivalent terms contain wake on WAN, remote wake-up, power on by LAN, power up by LAN, resume by LAN, resume on LAN and wake up on LAN. ![]() You can also initiate the message from another network by using a subnet directed broadcast or WOL gateway service.

The message is usually sent to the target computer through a program executed on a device (such as a smartphone) connected to the same local area network (LAN). WOL, which is the abbreviation of Wake On Lan, is an industry-standard protocol that supports waking computers up by a network message.
