Q1100020: When I do a Wake Up on LAN, the machine doesn't wake up at all. What's wrong?

Wake up on LAN (WOL) means that you can power on a computer by sending a sequence of packets over the network to that specific NIC card. Three conditions must be met:

  • Wake up on LAN must be supported by the remote computer's BIOS;
  • Somehow, there must be a link between the computer's NIC card and the BIOS. For NIC cards that are not integrated on the motherboard, a separate cable is needed to connect the NIC card to the motherboard;
  • A valid MAC address must be used to send the WOL message to.
