Solved: D-Link Router’s Power Button Won’t Stop Flashing

A D-Link router’s “Power” light flashing can indicate various issues, ranging from firmware problems to hardware malfunctions. Here are some steps you can take to troubleshoot and potentially resolve the issue:

  1. Basic Troubleshooting:
    1. Ensure the router is plugged directly into a wall outlet and not a power strip or surge protector.
    2. Check if the power adapter is the correct one for the router and that it’s not damaged.
    3. Disconnect all cables (including the power cable) from the router. Wait for about 1 minute, then reconnect the power cable.
  2. Hard Reset:
    1. With the router powered on, locate the reset button. It’s typically a small, recessed button that requires a paperclip or similar object to press.
    2. Press and hold the reset button for about 10-15 seconds.
    3. Release the button and wait to see if the power light stops flashing and becomes stable.

    Note: Performing a hard reset will restore the router to its factory settings. Any custom configurations you made will be lost.

  3. Firmware Recovery (Emergency Flashing):
    • Sometimes, a bad firmware update or a corrupted firmware can cause the power light to blink continuously.
    1. Download the latest firmware for your router model from the D-Link website.
    2. Boot the router in recovery mode (usually involves pressing the reset button while powering on the router, but check the user manual or D-Link’s website for specific instructions for your model).
    3. Using a web browser, access the router’s emergency web server (typically, and follow on-screen instructions to upload the new firmware.
  4. Hardware Issue:
    • If you’ve tried the above steps and the power light is still flashing, it’s possible there’s a hardware issue with the router. If it’s still under warranty, contact D-Link support or the place of purchase for a replacement.
  5. Environmental Factors:
    • Ensure the router is in a location with good ventilation. Overheating can cause erratic behavior. Make sure it’s not enclosed in a tight space or near other heat-producing devices.
  6. Try Another Power Adapter:
    • If you have another compatible power adapter, try using it to rule out the possibility of a faulty adapter.
  7. Contact D-Link Support:
    • If you’re unable to resolve the issue on your own, it’s a good idea to reach out to D-Link’s technical support. They may have additional troubleshooting steps or be able to determine if it’s a known issue with your router model.

If you’ve exhausted all troubleshooting steps and the router still isn’t working properly, it might be time to consider purchasing a replacement. Ensure you dispose of the old router responsibly by recycling it or dropping it off at an e-waste facility.
