Hello @JoVdw ,

Welcome to our community.

Here are some troubleshooting steps you can try:

• Use a different power adapter: If possible, test with another compatible TP-Link power adapter to rule out any issues with the charger.
• Perform a hard reset: Use a pin to press and hold the reset button (usually found in a small hole on the router) for about 10 seconds, until all the lights come on momentarily. This can sometimes restore the router if it is stuck during startup.
• Check the LED Control settings: If the router seems to work but the LEDs remain off, log into the router's web interface and check if the "LED Control" feature is enabled or disabled.

If none of these steps don't help,there may be a hardware fault that requires professional repair or replacement.

Please contact TP-Link support for further assistance.
