Description

The TP-Link TL-WN821N Wireless N USB Adapter is a compact USB wireless network card that supports IEEE 802.11n (Draft 2.0), IEEE 802.11g and IEEE 802.11b standards. It operates on the 2.4 GHz band and delivers wireless transmission rates up to 300 Mbps using MIMO technology and internal intelligent antennas. The adapter supports both Infrastructure and Ad-Hoc modes and connects via USB for easy installation on compatible Windows systems.

Advantages

The adapter offers wireless speeds up to 300 Mbps and improved range and stability thanks to MIMO and internal intelligent antennas. CCA (Clear Channel Assessment) technology helps avoid channel conflicts automatically. Security features include 64/128-bit WEP, WPA/WPA2 and WPA-PSK/WPA2-PSK, plus QSS (Quick Secure Setup) for fast wireless security configuration. The device supports QoS prioritization for bandwidth-sensitive applications like voice and video and is interoperable with 802.11g and 802.11n devices.

How to use
