Editing Wake-on-LAN (section)

===Responding to the magic packet===

Most WoL hardware functionally is typically blocked by default and needs to be enabled using the system BIOS/UEFI setup. Further configuration from the OS is required in some cases, for example via the [[Device Manager]] network card properties on Windows operating systems.

====Microsoft Windows====

Newer versions of Microsoft Windows integrate WoL functionality into the [[Device Manager]]. This is available in the power management tab of each network device's driver properties. For full support of a device's WoL capabilities (such as the ability to wake from an ACPI S5 power-off state), installation of the full driver suite from the network device manufacturer may be necessary, rather than the bare driver provided by Microsoft or the computer manufacturer. In most cases{{citation needed|date=March 2013}} correct BIOS/UEFI configuration is also required for WoL to function.

The ability to wake from [[hybrid sleep]] is not officially supported in Windows.<ref name="wolinwin">{{cite web |url= https://support.microsoft.com/en-us/kb/2776718 |title='Wake on LAN' (WOL) behavior in Windows 8 and Windows 8.1 |work=Microsoft |year=2015 |access-date=28 October 2015 |archive-url=https://web.archive.org/web/20160101213021/https://support.microsoft.com/en-us/kb/2776718 |archive-date=1 January 2016 |url-status=deviated}}</ref><ref>{{cite web |url=https://learn.microsoft.com/en-us/troubleshoot/windows-client/setup-upgrade-and-drivers/wake-on-lan-feature |title=Wake on LAN (WOL) behavior in Windows 10 |date=19 February 2024}}</ref><ref name="systempowerstates">{{cite web |url=https://learn.microsoft.com/en-us/windows/win32/power/system-power-states |title=System Power States |work=Microsoft |date=30 March 2023 |access-date=25 December 2024}}</ref><ref>{{cite web |url=https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c03774694|title=HP Support document |work=Hewlett-Packard Support Center |access-date=4 January 2018}}</ref> This is because of a change in the OS behavior which causes network adapters to be explicitly not armed for WoL when shutdown to these states occurs, so that those adapters don't consume power in what appears to the user to be a shutdown state, even though the system is just [[Hibernation (computing)|hibernating]]. WoL from a non-hybrid hibernation state when a user explicitly requests hibernation or a sleep state is supported. However, some hardware will enable WoL from states that are unsupported by Windows.<ref name="wolinwin" /><ref name="systempowerstates" />

====Mac hardware and macOS====

Modern Mac hardware supports WoL functionality when the computer is in a sleep state, but it is not possible to wake up a Mac computer from a powered-off state.

[[Mac OS X Snow Leopard]] and later support WoL, which is called Wake on Demand. On laptops, the feature is controlled via the macOS System Settings Battery panel, in the Options pop-up window. The ''Wake for network access'' item can be set to "Always", "Only on Power Adapter", or "Never"; "Always" enables Wake-on-LAN even when on battery power, but "Only on Power Adapter" enables it only when connected to a power supply. On desktops, the feature is controlled via the System Settings Energy Saver panel. Marking the ''Wake for network access'' checkbox enables Wake-on-LAN.<ref name="share-mac-resources">{{cite web |url=https://support.apple.com/guide/mac-help/share-your-mac-resources-when-its-in-sleep-mh27905/mac |title=Share your Mac resources when it's in sleep |website=Apple Support}}</ref> It can also be configured through the terminal using the ''pmset womp'' (wake on magic packet) command.
	
The [[Apple Remote Desktop]] client management system can be used to send Wake-on-LAN packets,<ref>{{cite web |url=https://support.apple.com/guide/remote-desktop/sleep-shut-down-log-out-or-restart-a-computer-apd5535ee19/mac |title=Sleep, shut down, log out, or restart a computer with Remote Desktop |website=Apple Support}}</ref> but there are also freeware and shareware macOS applications available.  A mechanism called [[Bonjour Sleep Proxy]], provided by Apple AirPort access points and Apple TVs, allows other machines on a LAN to cause a WoL packet to be sent to a host when that machine accesses one of the host's shared resources.<!--[[User:Kvng/RTH]]-->

====Linux====

Wake-on-LAN support may be changed using a subfunction of the [[ethtool]] command, for example:

<syntaxhighlight lang="shell">
ethtool -s eth0 wol g
</syntaxhighlight>
