Toshiba Satellite L640D Wifi
Searching for a new adapter is simple because all you need to know is what OS you are running on your laptop. 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 just plug it in, than it is to replace any type of OEM adapter you might have. The WiFi in your laptop, if so equipped, uses a piece of hardware in order to connect to your home router.

- Your wireless internet connection drops for no reason every day
- Your WiFi on your laptop is unable to connect to the internet
