Introduction

If your Dell Alienware M11x R3 has an issue joining Wi-Fi networks or cannot connect to any Wi-Fi networks, a new replacement for the Wi-Fi card will be needed.

A Wi-Fi card is what allows for a device to connect to the internet with Wi-Fi and without an ethernet cable. A new Wi-Fi card will be able to connect to the internet, presuming the Wi-Fi network is able to connect to other devices.

Before beginning this guide, make sure that the laptop is turned off completely unplugged from the power adapter.

What you need

1. Step 1 Lower Case
  Loosen the eight retaining screws on the base of the computer with a small Phillips screwdriver.
  
  The screws have retaining washers to hold them in place, so you don't have to remove them from the base plate.
  
  Remove the bottom cover from the laptop.
