TL-WN781ND

WHAT THIS PRODUCT DOES
TP-LINK TL-WN781N is designed to provide a complete end-to-end wireless performance from the server or server backbone to the switch infrastructure and down through to the desktop with the PCI Express connector. TL-WN781N Wireless Lite N PCI Express(x1) Adapter provides a wider compatibility, fitting with any standard PCI Express slot, x1, x2, x8, or x16. Compared with standard PCI network cards, it offers increased bandwidth, reliability and more functionality, allowing you to enjoy a fast and advanced connection, such as downloading, making internet call and video streaming.

Wireless N ---- Speed & Range
Complying with the IEEE 802.11n standard, TL-WN781N can easily establish a wireless network and get up to 9X the speed and 4X the range of conventional 11g products. Compared with legacy 54M products, TL-WN781N delivers performance enhancements, allowing you to have a more joyful surfing experience, including sharing files, watching streaming media.

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-WN781N provides WPA/WPA2 encryptions that are created by the WI-FI Alliance industry group, preventing the wireless network from outside threats.

Quick Setup Security
Compatible with WI-FI Protected Setup™ (WPS), TL-WN781N features Quick Security Setup (QSS) function, which is ideal for creating a WPA encrypted connection to prevent outside intrusion, and meanwhile maximize the management resources. Not only is this faster than normal security setups but more convenient in that you don’t need to remember a password!

Detachable Antenna
TL-WN781N offers external antenna that can be rotated and adjusted in different directions to fit various operation environments, and can bring better performance than the internal antenna. For even more demanding applications, the antenna can be replaced with diverse antennas to show even greater flexibility and wider wireless coverage.
