Dell Vostro A90 Wifi
Most USB wireless adapters are simply plug and play, which just means that you only need to put the adapter into an available USB port and the system will install the drivers automatically. The WiFi in your laptop, if so equipped, uses a piece of hardware to send and receive signals to and from your router and modem. It is much simpler to buy a common WiFi USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Buying a USB wireless adapter is quick and painless because all you need to know is the operating system that is installed on your Dell Vostro A90.
