Introduction
The Wi-Fi card, or wireless module, is what makes the laptop connect to a wireless network connection. A faulty Wi-Fi card can cause a unstable internet connection which means it needs to be replaced. Following this guide will show you how to replace a faulty Wi-Fi card (or upgrade to a newer one). In this guide you will be needing a Phillips #0 screwdriver, a plastic pick and a spudger.
This will take only a few minutes to complete and make sure to save any unfinished work as you will need to power down the laptop before you can begin.
