The Wireless-G USB Network Adapter with RangeBooster is the simple way to add or upgrade wireless connectivity in your desktop or notebook computer. RangeBooster technology is a compatible add-on to standard Wireless-G which increases your wireless network's range up to two times, and its throughput by up to 35%. Unlike ordinary wireless technologies that are confused by signal reflections, RangeBooster uses two smart receivers at each end to detect and decode reflected signals at distances where standard technologies give up. You'll find that "dead spots" in the wireless coverage area are reduced, too.
Unlike other range-enhancing technologies, RangeBooster is fully 802.11 compliant, and a "good neighbor" to other wireless devices and technologies, using a single 2.4GHz channel as specified by the official wireless standard. And with RangeBooster you'll see a range improvement even when running a mixed network of RangeBooster and regular Wireless-G and Wireless-B devices.
To install, simply plug the Adapter into any available USB port. (It's compatible with both USB 1.1 and 2.0 ports, but 2.0 will yield the fastest speeds.) It gets its power through the USB connection, so no power cord is necessary. The included Setup Wizard walks you through configuring the Adapter to your wireless network settings, step by step. Wireless communications can be protected by WPA 128-bit encryption, so your data stays secure.
The high-gain antenna lets you put your computer almost anywhere in the building, without the cost and hassle of running cables. Now you don't have to drill holes in your walls and climb through the attic or cellar to get connected to the network. Once you're connected, you can keep in touch with your e-mail, access the Internet, use instant messaging to chat with friends, play on-line games, and share files and other resources such as printers and hard disk storage space with other computers on the network.
