Motherboards will only support remote wake-up (or remote wake-up from S5 state) Response to ARP packets querying the first IP address in the list, usually the If multiple IP addresses are assigned to an adapter, the operating system may request to wake up on ARP patterns Directed and Magic - accepts the patterns of both directed packets and magic packets.Ĭhoosing "Directed Packets" will also allow the adapter to accept patterns of the Address Resolution Protocol (ARP) querying the IP address assigned to the adapter.

Magic Packets - accept only patterns containing 16 consecutive repetitions of the adapter's MAC address.Header or containing the IP address, assigned to the adapter, in the IP header. Directed Packets - accepts only patterns containing the adapter's Ethernet address in the Ethernet.OS Controlled - accept all the patterns sent by the OS.For Red Hat Linux, WoL is provided through the Ethtool* utility.
