I know Wake-on-LAN standard, but I don't understand the use case for Wake on Pattern Match option in the network card preferences. What are the advantages of it?

“Wake On LAN” makes the system wake on the “magic packet.”

The “Wake on pattern match” option instead checks for packets that matches the operating-system-specified patterns; for example, an ARP request for the computer’s address, or a TCP connection attempt.

The default patterns on a Windows 7 system are:

  • Magic Packet.
  • NetBIOS Name Query.
  • TCPv4 SYN.
  • TCPv6 SYN
  • IPv6 Neighbor Solicitation.

There’s no ARP in the list since the device is expected to support “ARP Offload”; that is, reply to ARP requests with OS-set address by itself.

Does anyone know if an article exists explaining the other advanced features available for network interfaces on Windows? Google doesn't turn up any quality results for all but a few of the more obvious options. – Hydranix – 2016-03-30T04:28:43.780

Only by disabling Wake on Pattern Match on my network card could I wake my computer over the Internet. Important note: this option did not impair waking over LAN. – NikolaiK. – 2016-07-08T21:54:25.200
