802.11b+ Wireless LAN USB Adapter
Where to buy


Adjustable Antenna
With its unique flip-up, adjustable antenna design, and the included USB cable, the DWL-120+ can be positioned virtually anywhere in a workspace to achieve the best available wireless signal reception.

Network Security
Security is an issue when data is transmitted without the wires. In the air, transmitted data can be easily intercepted if not well protected by a security scheme. The DWL-120+ provides the necessary security, using the enhanced 64/128/256-bit industry-standard WEP (Wired Equivalent Privacy) encryption protocol.

Easy Installation
With hot swap and plug-and-play capabilities, the DWL-120+ can be easily plugged to either your notebook or desktop computer to provide connectivity to another 802.11b, 802.11b+ or 802.11g wireless enabled device (ad-hoc mode) or through an Access Point (infra structure mode).

Portable Pocket-sized
With its antenna folded up, the DWL-120+ is an attractive, portable wireless device. It can fit into your pocket or carrying case, allowing you to easily carry it around.
