Description
TP-LINK's TL-WN781N is designed to provide end-to-end wireless performance from the server or server backbone to the switch infrastructure through to the computer with the PCI Express connector. The TL-WN781N Lite N PCI Express(x1) Wireless Adapter offers high compatibility, fits into any standard PCI Express slot, x1, x4, x8, or x16.
Compared to standard PCI network cards, it offers more bandwidth, reliability and functionality, allowing you to enjoy a fast and advanced connection for your downloads, Internet calls or video streaming.
Compatible with IEEE 802.11n, 802.11g and 802.11b standards, TL-WN781N Lite N PCI Express Wireless Adapter can adapt to all 802.11n/b/g devices. With WMM based on IEEE 802.11e, it provides QoS (Quality of Service) and prioritizes network traffic. Moreover, the WMM Power Save function ensures low power consumption for eco-friendly operation.
The TL-WN781N features Quick Security Setup (QSS), which is ideal for establishing an efficient and secure connection that prevents unauthorized access while maximizing management resources. With its detachable external antennas, the TL-WN781N adapts to various environments and ensures easy installation.
This device has a self-running CD that provides detailed step-by-step information for establishing an Internet connection quickly and easily, within the reach of any user, even the most inexperienced.
Why is AlignTM technology better?
AlignTM is a technology developed by Atheros Communications, Inc., a leading developer of advanced semiconductor system solutions for wired and wireless communications. Based on the IEEE draft 802.11n 1-stream specifications, the single-stream feature enables a new class of Wi-Fi® devices that offer performance improvements over current 802.11g technology at similar price points. Align solutions are backward compatible with higher performance, multi-stream, MIMO-based 802.11n versions and provide the best upgrade path for entry-level WLAN models. Users migrating from 802.11g products to products based on Align 1-stream technology will enjoy increased performance in their home networks.
