Dell Inspiron M4040 Wifi
Buying a wireless adapter is quite easy because all you need to know is the operating system that is installed on your laptop. The WiFi in your laptop, if so equipped, makes use of a wireless adapter to send and receive signals to and from your router. You are better off buying a common WiFi USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Most USB wireless adapters are simply plug and play, which means you simply plug it into a USB port and the system will install the drivers automatically.
