High Power Wireless N USB Adapter

TEW-645UB (Version V1.0R)

  • 2x the coverage of standard wireless n and 8x the coverage of wireless g adapters*
  • Connect your laptop or desktop to a high speed wireless n network
  • Position the included USB base to capture the strongest wireless signal
  • Advanced wireless encryption and Wireless Multi Media (WMM) QoS technology

The TEW-645UB (Version V1.0R) has been discontinued.  It has been replaced by the TEW-684UB (Version V1.0R). For a list of discontinued products, click here.

The High Power Wireless N USB Adapter provides over 2x the wireless coverage of standard wireless n and up to 8x the coverage of wireless g adapters*.

Connect your laptop or desktop computer to a high speed wireless n network and position the included 1.5 m (4.9 ft) USB base to capture the highest wireless signal strength.

Connecting to a wireless network is a breeze with automated Wi-Fi Protected Setup. Advanced wireless encryption ensures the highest data security. Wireless Multi Media (WMM) Quality of Service technology prioritizes streaming video, wireless gaming and online calls**.

**Maximum wireless signal rates are referenced from IEEE 802.11 theoretical specifications. Actual data throughput and coverage will vary depending on interference, network traffic, building materials and other conditions.
