Power LED Off

How to Fix It

1. Check the power adapter.

   Confirm the adapter is fully plugged into the wall and the router.
   Push the barrel connector firmly into the router's power input — sometimes it backs out partly.
   If using a power strip, confirm the strip is on and not tripped.

2. Test the wall outlet.

   Plug a known-good device — phone charger, lamp — into the same outlet.
   If the test device works, the outlet is fine.
   If not, the outlet, breaker, or strip is the issue.
   Reset breakers in your panel if needed.

3. Try a different outlet.

   Move the router and adapter to a different room's outlet.
   If the router lights up there, the original outlet had the issue.
   If the router still has no LED, the adapter or router is at fault.

4. Test the adapter on a known router.

   If you have a spare Asus router or any device that uses the same DC voltage and barrel size, test the adapter there.
   If the test device powers up, the adapter is fine — your router is the issue.
   If neither works, the adapter is dead.

5. Replace the adapter.

   Asus replacement adapters are 15-30 USD.
   Match the voltage and amperage on the original adapter exactly — wrong voltage damages the router.
   Avoid generic universal adapters with adjustable voltage; they often run noisy.

6. Check for surge damage.

   After lightning storms or major power surges, routers can fail without external signs.
   Plug the router into a different outlet on a different circuit.
   If still no LED, the surge likely killed the router.

7. Hold reset for 30 seconds.

   Some routers latch into a fault state after a surge.
   With the adapter plugged in, hold the reset button for 30 seconds.
   Release.
   If the router was stuck, the LED comes back.

8. Replace the router if dead.

   Asus routers are 100-500 USD depending on model.
   If a known-good adapter does not power up the router, replacement is the answer.
   Use a UPS with surge protection for the new one to prevent recurrence.
