The TP-LINK Archer T2UH Wireless AC600 Dual-Band High-Gain USB Adapter is perfect for HD streaming, online gaming and other bandwidth-intensive tasks. The adapter offers two frequency bands to separate your high-bandwidth activity from light browsing and emails, ensuring each task is completed with a stable and fast connection.
