![]() ![]() If the 2 subnets are linked by a firewall type device than prevent broadcast of packet to the whole subnet, then MC-WOL is not going to work, because MC-WOL broadcasts the magic packet to the whole subnet. On a Dell Optiplex computer, it looks like this:Īs explained above, you can use MC-WOL to wake up a computer on a subnet different from yours. They generally include, in their names, words like “WOL”, “Magic packet”, “power management”… They are different from computer to computer, of course, but the ones to enable are usually easy to identify. Launch Device Manager, select the network adapter used for WOL, open the properties and click the “advanced” tab.Ĭheck the list of options displayed. Boot Windows and log on as an administrator. Then, you need to set up the network adapter options in Windows to enable WOL. On some computers, if fast boot is enabled, it disables WOL. Enter the BIOS, and look for a setting called “WOL, “Wake up ON LAN”, “Remote wake up”… Set this setting to “enable”. You have to look at the settings of the computer that you want to wake up. If the computer powers on, then it’s all good ! If not, well, it is not over. If the computer is on a subnet different from yours. Or \mc-wol MAC_address /a subnet_broadcast_address Get the MAC address of the computer that you want to power on, and, from the command line, launch the following command: This is the software that send the magic packet. Then, get the MC-WOL free software from here. The best thing to do is to try first to power on a computer through WOL to see if it works.įor that, you will need an already powered on computer (yours !) connected to the network. Have a look at the network card : if you can see some LED blinking on it while the computer is powered off, it is certainly able to manage the computer power status. Most of computers that are less than 5 years old have nowadays such a network card. You need a computer with a network card that accepts Magic packets and that is able to manage the computer power status. Not all computers can be powered on this way. The client to which this “magic packet” is sent then powers on by itself. It is quite simple: a computer, with a dedicated software, sends a signal across the network called a magic packet.

A very interesting feature to set up on the client computers that you manage is Wake up On LAN, or WOL. ![]()
