High-Gain802.11b/g Wireless USB Adapter with Rotatable Connector Design

The WCU5102 enables you to connect your desktop computer or laptop easily to any 802.11b/g network via a USB connection. With a clever USB connector design, which allows you to swivel and rotate to almost any angle plus the Hi-Gain antenna technology, the WCU5102 not only provides a highly concentrative capability to have a wireless connection of quality but also extends the wireless connection distance up to three times further! A compact base stand goes with the Wireless LAN USB Adapter is a convenient option for the desktop use. What’s

even more marvelous is the built-in LED signal strength indicator, which pinpoints the strongest signal available within your wireless LAN! The WCU5102, a small and compact wireless device, is definitely the best choice to carry around for enabling the wireless environment!
