Alienware M18X Wifi
It will be easier to buy a common WiFi USB adapter and install it, than to replace any built-in adapter your laptop may have. The WiFi in your laptop, if so equipped, uses a piece of hardware to send and receive signals to and from your home network. Most new Wifi adapters are simply plug and play, which means you simply plug it into a USB port and the operating system will take care of the rest. Finding a WiFi adapter is easy because all you need to know is what OS you are running on your Alienware laptop.
Clues of a defective onboard WiFi
- Your wireless internet connection drops multiple times over and over again
- The WiFi adapter in your Alienware laptop is unable to connect to the internet
- The laptop wireless driver shows it as not installed
