Wake On LAN settings to start Windows remotely

Wake On LAN (WOL) is a function implemented by a network adapter (NIC) that can send a signal called a magic packet to the NIC to start a personal computer.

Even if the computer to which the power cable is connected is shut down, standby power is supplied to the motherboard, so when WOL is enabled, Start button It will be possible to boot the PC from a local network or an external network using an application that replaces.

Power status

ACPI (Advanced Configuration and Power Interface) is a power management standard.S0 ~ S5 The sleep state up to is specified.

S0Normal operating condition
S1stand-by
S2suspend
S3sleep
S4Pause / hibernation (hybrid shutdown)
S5Power off

sleep (S3) is a state where power supply other than memory is stopped, and Windows is shut down. Power off (S5).

Shutdown / Hybrid Shutdown

Windows 8 or later Windows shut down The Power off Of S5 から S4 Of Hybrid shutdown ,All devices have the lowest power state (D3) It has becomeWake On Lan booting from classic shutdown (S10) and hybrid shutdown (S11) states is not supported on Windows 5/4.

Microsoft Hardware Dev Center Ethernet
· Wake On Lan is only supported from sleep (S3) or hibernate (S4) state.

· Wake On Lan is not supported in Classic Shutdown (S5) and Hybrid Shutdown (S4) states.

BIOS / UEFI settings

WOL works before Windows boots, so in BIOS / UEFI Boot from PCIeBoot from LAN Setting is required.

Since the BIOS / UEFI setting items differ depending on the motherboard you are using, refer to the motherboard manual or the PC manufacturer's instruction manual for details.

Router settings

The WOL signal sent to the router is MAC address , Node ID It contains a unique identification number attached to the network adapter, also known as, and the router sends a WOL signal to the IP address previously associated with the MAC address.

The standard that identifies the MAC address from the IP address ARP (Address Resolution Protocol) where the data was saved ARP table However,Depending on the router model, the ARP table will be destroyed after a certain period of time.Therefore, even if a magic packet is sent, the router loses track of the IP address associated with the MAC address, the transmitted WOL signal does not reach the specified PC, and as a result, the PC does not start.After setting WOL, the PC can be shut down and started within tens of minutes, but if you try to start with WOL after waiting for several hours or more, a special phenomenon occurs that it does not respond..

Port open

The router that connects the Internet to the computer has security to protect the computer from threats such as worms, and the router also sends WOL signals from the outside. Suspicious signal It is necessary to set the signal to pass because it is cut off.
