D-Link Router’s Power Button Won’t Stop Flashing, What to Do?

Interpreting the Flash

Firmware Upgrade/Recovery: A flashing power light indicates the D-Link router is attempting to update its firmware or is in firmware recovery mode.

Patience (Initially): Wait for about 10-15 minutes. If the update/recovery is successful, the flashing should stop, and the router will start functioning normally again.

Boot Loop: If the flashing continues for an extended period, it will mean that the router is stuck in a boot loop and it’s unable to fully start.

This can be caused by:

  • Corrupted Firmware: An interrupted firmware update or a bug can cause corruption of the core files for your router.
  • Hardware Problem: Failing internal components will also prevent your router from booting properly.

Troubleshooting Steps

The Power Cycle:

Unplug your router from power for 30 seconds to 1 minute then plug it back in. This will usually break a boot loop.

Firmware Recovery Mode:

To force your D-Link router into firmware recovery mode hold the reset button and the power button down at the same time.

If successful, you may then be able to re-flash the firmware through the D-Link router’s web interface.

Forced Reset:

If the previous option still doesn’t work you can just force reset all the settings on the D-Link router by pushing the small button labeled as “reset” on the back of the router for 30 seconds. This will usually solve the power button flashing issue.

Advanced Recovery (TFTP):

Some D-Link routers have TFTP recovery options, which involve using a specialized tool to send the firmware file to the router during a specific time in the boot process. See if your D-Link router has this option and use it if none of the previous solutions worked.

Hardware Failure

Age of the Router: If your D-Link router is older, a flashing power LED will indicate a failing power supply or more generic hardware issues like a burnt transistor or something on the circuit board.

Overheating: Check if the router is abnormally hot. Overheating will damage components and cause boot problems. Put the router in a properly ventilated area that it’s not in a confined space.

Physical Damage: Any physical damage from drops, spills, etc. likely damaged the internal components of the routers.
