WHAT THIS PRODUCT DOES
TP-LINK Wireless N USB Adapter TL-WN821NC is designed to provide advanced wireless connection for small business and home office networking requirements, delivering better signal than legacy 802.11g products, which is beneficial for the video streaming or online gaming. Base on the WPA/WPA2 encryption mechanism, a highly secured wireless connection could be established simply at a push of QSS (Quick Setup Security) button, preventing the network from outside threats. Specially, TL-WN821NC comes with a USB cradle and extension cable, which is convenient for users to install the adapter, even for desktop users.

Wireless N ---- Speed & Range
Complying with the IEEE 802.11n standard, TL-WN821NC can establish a wireless network and get up to 15X the speed and 5X the range of conventional 11g products. Also, with MIMO (multiple input, multiple output antennas) technology, it shows more excellent abilities of mitigating data loss over long distances and through obstacles in a small office or a large apartment, even in a steel-and-concrete building. Above all, you could easily pick up the wireless network during long-distance connection where legacy 11g products may not!

SST & CCA Technology ---- Stable Wireless Signals
Signal Sustain Technology (SST) dramatically increases link robustness and throughput by simultaneously transmitting across three spatially-diverse signal paths, and incorporating information from three receivers.
Clear Channel Assessment (CCA) automatically avoids channel conflicts using its clear channel selection feature and fully realizes the advantages of channel binding, greatly enhanced the wireless performance.

WPA / WPA2 Encryptions ---- Advanced Security
As for the security of WI-FI connection, WEP encryption has been no longer the strongest and safest guards for outside intrusions. TL-WN821NC provides WPA/WPA2 encryptions that are created by the WI-FI Alliance industry group, promoting interpretabilities and security for WLAN, which could effectively and efficiently protect the wireless network.

One Button Security Setup
Compatible with WI-FI Protected Setup™ (WPS), TL-WN821NC features Quick Security Setup that allows users to almost instantly setup their security simply by pressing the "QSS" button automatically establishing a WPA2 secure connection, which is more security compared with WEP encryptions. Not only is this faster than normal security setups but more convenient in that you don’t need to remember a password!

Bundled USB Cradle
TL-WN821NC equipped with the USB cradle and 1.5m extension cable, which allow you to save USB port space, and extend the USB connection length up to 5 feet, making it more convenient to plug the USB device in & out of the USB socket, even fot desktop users. Its elegant and stylish design is suitable for home deployment and will even improve the look of your home and office.

Bundled CD for easy operation
TL-WN821NC comes with a CD with utility that helps you complete the software installation and wireless network settings, including security configurations and wireless connection, which is convenient for users, even for novice users.
