Wake on LAN (WoL) is one of those incredibly useful features that I had forgotten about having used in the dim distant past. As the name suggests, it wakes up a PC by sending it a “magic packet” across a network. To get it all to work you need several things in place:
1. a network card that supports WoL - all should now
2. the network card with WoL enabled. Do this in Device Manager, and in your card properties check all the settings under “Power Management” and then also under “Advanced” make sure “Wake on Magic Packet” is enabled.
3. it’s easier if you PC has a fixed IP on your (home) network - do this in “Control Panel” then Network and Sharing Center->View network status and tasks->Change adapter settings then right-click on “Ethernet” (or what your network card is called) and Properties. Under “Internet Protocol Version 4”, use Properties to set the IP address.
4. the PC can only wake for “Sleep” or “Hibernation” so make sure your PC is in one of these two states. By default Hibernation (which is the lowest power mode) is off in Windows 10. To make this accessible goto “Control Panel” then Power Options->Change what the power buttons do. If Hibernate is unticked, click on “Change settings that are currently unavailable”, tick it then “Save Changes”
5. I wanted my machine to resume to the main screen and bypass login - to enable this goto “Settings” then Accounts->Sign-in Options and change “Require sign-in” to Never.
5. YOU’RE THERE!! Now you only need a way to wake your machine - I installed the aptly named “Wake on Lan” Play store app which just works.
In terms of application, for me it allows me to remotely start my desktop and then remote desktop in. I can’t help but think that this should be one of those things that “just works” rather than having to jump through so many hoops!
