How to Enable or Disable Wake on LAN (WOL) in Windows 11
Wake on LAN (WOL) in Windows 11 lets you power on your PC remotely using a special “Magic Packet” sent over your network.
This feature is incredibly useful for accessing your computer from another location without needing physical access, essentially waking it from sleep or hibernation as if you pressed the power button.
You can enable or disable Wake on LAN directly through Windows 11 settings, or via your adapter’s properties in Device Manager, with options accessible even through the command line for advanced users.
You might need administrator privileges and to disable “Fast Startup” for WOL to function correctly.
Open Device Manager, expand Network adapters, double-click your Ethernet adapter, and adjust settings under the Advanced and Power Management tabs. Alternatively, use the Settings app under Network & internet > Advanced network settings.
Troubleshooting: Why Won’t My PC Wake?
If your Windows 11 PC isn’t waking up with Wake on LAN, it’s usually because of a couple of common settings you can check.
- Fast Startup: This Windows feature can block WOL. Disable it in Control Panel > Power Options > Choose what the power buttons do.
- Network Drivers: Ensure your Ethernet controller drivers are updated.
- Power Management: Verify the Power Management tab settings in your network adapter properties.
- BIOS Settings: Ensure the S3/S4/S5 sleep states are configured to allow wake events.
How to Send a Magic Packet
To test if your setup works, use a tool like WakeMeOnLan by NirSoft. This utility allows you to scan your network and send the necessary packet to wake your target machine. Simply run the tool, select your PC, and click the wake button.
Summary
Getting Wake on LAN working in Windows 11 means you can turn on your PC from anywhere, which is really useful for remote access.
Does Wake on LAN work over Wi-Fi?
Generally, no. Most network adapters need a wired Ethernet connection to listen for a Magic Packet when your computer is sleeping. Some newer Wi-Fi cards can do ‘Wake on Wireless LAN,’ but it’s usually not as reliable as a wired Ethernet connection.
Why does Wake on LAN stop working after a Windows update?
Windows updates often reset network adapter drivers or power management settings to their defaults. If an update occurs, check your Network adapter properties again to ensure the ‘Allow this device to wake the computer’ box remains checked and that the driver has not been replaced by a generic version.
What is the difference between S3 and S5 wake states?
Understanding S3 and S5 wake states is important for Wake on LAN in Windows 11.
Do I need a static IP for Wake on LAN?
You do not strictly need a static IP for local network wake-ups. However, if you are waking your PC from outside your home network, a static IP or a Dynamic DNS service is highly recommended so your router knows exactly which device to send the Magic Packet to.
