The D-Link RangeBooster N USB Adapter (DWA-142) is a draft 802.11n compliant wireless client designed for desktop or notebook PCs that delivers up to 12-times faster speeds and 4x farther range than 802.11g and 802.11b networks. 

Once connected, users can share a high-speed Internet connection, photos, files, music, printers and more, says Tiens Lange, D-Link brand manager at Pinnacle Micro.
“The DWA-142 adapter is powered by RangeBooster N technology to provide high wireless performance in the home or office,” he says. “Connect to a RangeBooster N Router, like the DIR-625, and users can experience smooth Internet phone calls (VoIP), responsive network gaming, secure Web surfing, faster file transfers, enhanced audio streaming and greater wireless coverage in larger homes and offices.”
The DWA-142 supports WEP, WPA, and WPA2 encryption that allows users to connect securely to a wireless network.
The Quick Adapter Setup Wizard guides users step-by-step through the installation process. The Manager is also included with the product to keep track of the most frequently accessed networks so users can join them quickly and easily. The DWA-142 is a good choice for easily adding or upgrading wireless connectivity to the desktop or notebook PC.
