What This Product Does
Wireless N USB Adapter TL-WN821N allow you to connect a desktop or notebook computer to a wireless network and access high-speed Internet connection. Comply with IEEE 802.11n, they provide wireless speed up to 300Mbps, which is beneficial for the online gaming or even HD video streaming.
Wireless N Speed & Range
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!
Advanced WPA / WPA2 Encryptions Security
As for the security of WI-FI connection, WEP encryption has been no longer the strongest and safest guards for outside intrusions. TL-WN821N 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 CD for Easy Operation
TL-WN821N 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.
