Dell Alienware M11X Wifi
A lot of newer wireless adapters are plug-n-play, in that you just plug it in the USB port and the operating system will take care of the rest. It is much simpler to buy a new wireless USB adapter and install it, than to replace any built-in adapter your laptop may have. Buying a USB wireless adapter is quick and painless due to the fact that all you need to know beforehand is what OS you are running on your Dell laptop. The WiFi in your laptop, if so equipped, uses a piece of hardware to send and receive signals to and from your home network.
Main clues your internal WiFi is failing
- The WiFi adapter driver cannot be installed
- The WiFi adapter on your laptop will not connect to your router anymore
- Your WiFi signal drops for no reason during the day
