WiFi Repeater Rescue

Introduction

I have been using a cheap, no-name wifi repeater in our house for about a year. It is of the type that you plug in a mains socket on the wall (after configuring it with a computer) and you forget about it. It's done a good job (i.e. zero maintenance) until a few days ago, when one day I realized it was not working. Only its red power LED was blinking, and we all know the red lights, especially blinking ones mean no good.

The two antennas are stuck to the back of the front panel.

Since it's a cheap model, I immediately ordered a new one, but it would take several days to arrive, so I decided that before throwing it away, I would open it up and see what's inside, how it works, and maybe salvage some of the internals for later projects.
