简介

When you power up the router, after 4 seconds the power light changes from green to yellow.

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.

    • 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.

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