TP-Link TL-WN881ND 300Mbps Wireless N PCI Express Adapter

TP-Link's TL-WN851ND wireless N PCI adapter lets you connect your desktop computer to a wireless network and access it at high speed. Compliant with the IEEE 802.11n standard, it offers a wireless speed of up to 300 Mbps, perfect for online gaming or video streaming.
It features MIMO (Multiple Input, Multiple Output) technology. This lets you minimize signal loss caused by obstacles in large offices or apartments, even steel and concrete structures. As a result, it's able to easily pick up a wireless signal broadcast over a long distance, unlike using a previous-generation 11g device.
The Clear Channel Assessment (CCA) feature automatically avoids channel conflicts by using the optimal channel selection function, while maximizing the benefits of channel bonding for greater wireless performance.
The WPA/WPA2 encryption standard ensures your wireless connection is secure against intruders.
Using the optimized user interface and setup wizard on the included CD, you'll be online quickly and easily.
