Troubleshooting Wake On LAN on a Windows PC
Here are some steps you can take to troubleshoot issues when trying to wake a PC.
- The computer you are trying to wake up must be on a wired connection (not on WiFi)
- A second Host computer must be switched on and in the same network in order to send the wake request
Important: Make sure you are using up to date, officially supported third-party technology together with the host software. The host software is designed for use with third-party products and services (browser, OS, etc.) that are officially supported by their respective vendors and well-maintained by the end user (latest patches and updates installed).

To ensure best results, make sure the following items are using up-to-date drivers or firmware:
- Motherboard Chipset
- Network Adapter (if you have recently updated to Windows 10, make sure the Network Adapter drivers are updated)
Tip: In the BIOS under Power Management, Deep Sleep must be turned off.
Consult your computer or hardware manufacturer for assistance in downloading and installing drivers and firmware.
Tip: When Wake On LAN is possible, the LED light of both your network adapter and ethernet port should be lit up or blinking. These are commonly located on the back of your computer. If these lights are not lit up or blinking, the issue is with your network adapter or ethernet port hardware and you may want to contact the manufacturer.
