Wireless USB Adapters
WiFi wirelessUSB network adapter. These adapters connect to a standard USB port available on the back of most newer computers. In general, USB network adapters are not much larger in size than PC Card adapters. Two LED lights on the adapter indicate its power and network link status.
Installation of a wireless USB adapter is simple. A short USB cable (normally included with the unit) joins the adapter to the computer. These adapters do not require a separate power cord, as the same USB cable also draws power from the host computer. The USB adapter's wireless antenna and circuitry remain external to the computer at all times. On some units, the antenna can be adjusted manually to improve WiFi reception. The accompanying device driver software serves an equivalent function as in other types of network adapters.
