TP-Link TL-WN821N 300Mbps Wireless N USB Adapter (White)

Wireless N USB Adapter TL-WN821N allows 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
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!
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
WI-FI Protected Setup (WPS) allows users to almost instantly setup their security simply by pressing the WPS button automatically establishing a WPA2 secure connection, which is more security compared with WEP encryptions. Not only is this faster than normal secure setups but more convenient in that you don't need to remember a password!
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
