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, x4, 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. Complying with IEEE 802.11n, 802.11g and 802.11b standards, the TL-WN781N Wireless Lite N PCI Express Adapter can perfectly interoperate with all the 802.11n/b/g devices. With WMM based on the IEEE 802.11e, it provides Quality of service (QoS) and prioritizes the network traffic. Also, WMM Power Save guarantees lower power consumption for environmental work. TL-WN781N features Quick Security Setup (QSS) function, which is ideal for creating an efficient and safe connection to prevent outside intrusion, and meanwhile maximize the management resources. With the external and detachable antennas, the TL-WN781N can fit different operation environment and guarantee the easy installation. The device comes with an auto-run CD that provides information about completing the internet connection step by step, which is quickly and hassle-free for any users, especially for novice users. Why AlignTM technology is better? AlignTM technology is announced by Atheros Communications, Inc, which is a leading developer of advanced semiconductor system solutions for wireless and wired communications. Based on the IEEE draft 802.11n 1-stream specification, the single-stream feature enables a new class of Wi-Fi® devices that deliver performance enhancements over the existing 802.11g technology, at comparable price points. Align solutions are also forward compatible to higher-performance, multi-stream, MIMO-based 802.11n - providing the optimal upgrade path for value-class WLAN products. Consumers who move from 802.11g to products based on Align 1-stream technology will experience enhanced performance in their home networks.
