The TP-Link 150 Mbps High Gain Wireless USB Adapter allows you to connect a desktop or notebook computer to a wireless network and access a high-speed Internet connection. Compliant with IEEE 802.11n, it provides wireless speeds up to 150 Mbps, which is great for online gaming or video streaming. Using Align TM 1-stream technology based on 802.11n technology, the adapter gives you a more robust wireless signal than existing wireless 802.11g technology can provide. The adapter demonstrates an excellent ability to curb data loss over long distances and through obstacles in a small office or a large apartment--even in a steel-and-concrete building! You can easily pick up the wireless network during long-distance connection, where legacy 11g wireless products may not be able to do so.
