Troubleshooting Common Wol Issues

Encountering issues with Wake on Lan (WoL) in Home Assistant can be frustrating.

Whether it’s a device that won’t respond or a network hiccup, troubleshooting is key.

Let’s diagnose and solve these common problems together.

Diagnosing Connectivity Challenges

Is your device not waking up as expected with WoL commands?

Start by checking the basics:

  • Ensure the device supports WoL.
  • Confirm WoL is enabled in BIOS settings.
  • Check if network configurations are correct.

Use dedicated tools to send WoL packets:
