Manufacturer SKU: TL-WN781ND

Details:

The TL-WN781ND is designed to provide 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-WN781ND Wireless N PCI Express (x1) Adapter provides 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.

Wireless N -Speed & Range

Complying with IEEE 802.11n standards, TL-WN781ND 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-WN781ND delivers considerably enhanced Internet performance.

WPA / WPA2 Encryptions - Advanced Security

TL-WN781ND 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-WN781ND features the 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-WN781ND features an external antenna that can be rotated and adjusted in different directions to suit various environments. For even more demanding applications, the antenna can be replaced with alternative antennas to improve wireless coverage.
