Difference is that when computer is switched-off it doesn't have any IP address, therefore you need to forward WOL packets to all devices (MAC addresses) on the network. This can work in a similar way as a standard port forwarding on a router. In theory any UDP port can be used for WOL, but normally UDP ports 9 and 7 are used. To make this work you need to forward all WOL magic packets coming from the Internet to your LAN network.
However, the most useful WOL feature is ability to wake up remote computer over the Internet.įirst of all if you are on residential broadband, your ISP most likely have issues you with a dynamic IP address. If you only intend to use WOL on your local LAN network you can skip this part. Some PCI cards need to be additionally connected via a special WOL cable to the motherboard, or be plugged in into a specific PCI port. However if you use an external or PCI network card, check card's compatibility as well. If your motherboard and BIOS are compatible with WOL, integrated network card will be compatible too. Or you can just disable all of them to start with. There should be explanations next to each mode. Some of them may be not compatible with WOL. Most of the modern computers will have this option, however if you have very old hardware you may be out of luck.Īlso check for power saving modes in BIOS. Normally it's under " Power Management" section and can be called Wake-on-LAN, Remote Wake-up, or something similar. WOL works fine over HomePlug.įirst of all boot into BIOS (when computer boots press F2, DELETE, or other depending on your motherboard model) and enable WOL support. As an alternative to wireless you can use one of many available HomePlug devices. You should use Ethernet network connection as WOL in most cases will not work over wireless (there are exceptions).
This includes motherboard, BIOS and network card.
In order to use this protocol first of all you must have compatible hardware. Wake on LAN (WOL) is a platform independent networking standard which allows to "Wake-Up" (resume from shut down / hibernate / sleep) a computer remotely by a specifically crafted network message called magic packet.
