Introduction

Sometimes this is related to a corrupted firmware, but other times is related to a faulty power supply.

In this guide I’ll show you how to diagnose this issue and fix by replacing one single component from the power supply.

What you need

Step 1

              Open the power supply
  • Insert your X-Acto knife on the groove in order to remove part of the glue that is holding the two parts.

Step 2

              Open the power supply
  • Using your prying tools or a butter knife, slide it in and then bend it until you ear it pop.

Step 3

              Open the power supply
  • On the board of the power supply you’ll probably see the faulty capacitor. Is the one on the right that has swollen.

Step 4

              Replace the capacitor
  • The capacitor has a right position. Mind the markings on the capacitor and the board, they must match.
  • I used a 1000uF 25V that I’ve removed from an old CRT monitor, but the recommended one is a 1000uF 16V or 1000uF 10V (like the original).
  • Using the soldering iron, desolder the faulty capacitor and solder a new one.

Step 5

              All good!
  • Reassemble the power supply and your router should be back and running fine :)
