Some routers will pass what is called a directed broadcast. If it's a router that you control in your own domain, you *may* be able to configure it to do so - someone else would need to comment on this possibility. I have read elsewhere that routers do not forward broadcast packets. If you mean a machine on a different subnet and your magic packet has to be passed outside your local router, I doubt that this is possible. S5 = Active Off (enable "Wake on Magic Packet from power off state" to allow wakeup from this state) S3 = Standby (enable "Wake on Magic Packet" to allow wakeup from this state) You would generally find this on really old cards & motherboards (more than 5 years old). Note also that for certain add-in Ethernet adapters (PCI) and mother boards you may need to connect a 3-wire "WOL Cable" (from header on card to header on motherboard) for the WOL Capability to work. You would need to enable the 2 Wake on Magic Packet options (I leave the other 2 disabled).ĢD. These are what I have for an Intel PRO/1000 Ethernet adapter on my machine. "Wake on Magic Packet from power off state"
#MAC WAKE ON LAN FROM POWER OFF DRIVER#
(This may or may not be there and the name will vary, depending on the manufacturer of your Ethernet adapter & the driver you have installed.)Į) If you do have a Power Management tab, look for options that enable/disable any of the following:

Modern power supplies supply a trickle voltage to the computer's motherboard (in "active off" mode) this is routed to the Ethernet adapter, among other things.ĢC. Note that your machine's power supply must also support this capability if your power supply does not have its own "master" on/off switch, it's likely that it's not compatible. Go into the machine's BIOS and look for a setting that enables WOL. Verify that the machine you're trying to wake supports Wake on LAN ("WOL") functionality: Verify that the MAC address you have is correct.Ģ. If you mean a different machine on the same subnet (i.e. An " external machine within the network".
