With TeamViewer Remote, you can wake up a computer directly via its public IP address. Through its built-in WoL capabilities, TeamViewer Remote allows you to turn on offline devices from anywhere. If the MAC address is valid, it powers on or wakes the device. When the WoL-enabled NIC receives the magic packet, it checks it for the correct information. It contains a header and the target device’s media-access-control (MAC) address – a unique identifier assigned to each NIC. The magic packet is designed specifically to be processed quickly and easily by the NIC using very little power. To wake up a target device, the WoL software broadcasts a small data signal known as a magic packet to the NIC of the target device, either on the broadcast address for that device’s particular subnet, or on the address for the entire local area network (LAN). in soft-off or hibernate mode), there is sufficient power for the device’s network interface card (NIC) to remain receptive to communications in standby mode.

This means that although the rest of the device is powered down (e.g. Originally developed by AMD and Hewlett Packard, WoL is a well-established networking protocol that has been in use since the 1990s.įor Wake-on-LAN software to work, the remote computer you want to control must have its WoL settings enabled.
