TP-Link TL-WN881ND 300Mbps Wireless N PCI Express Adapter, Atheros, 2T2R, 2 detachable antenna (ships with low profile adaptor)

What This Product Does
The TL-WN881ND Wireless N PCI Express 2.0(x1) Adapter allows you to connect a desktop computer to a wireless network and access high-speed Internet. Complying with IEEE 802.11n, they provide wireless speeds of up to 300Mbps, which is beneficial for online gaming or even HD video streaming.

Wireless N - Speed & Range
MIMO (multiple input, multiple output antennas) technology helps mitigate data loss over long distances and through obstacles in a small office or a large apartment. Above all, you can easily pick up the wireless network over long-distances.

CCA Technology - Stable Wireless Signals
Clear Channel Assessment (CCA) automatically avoids channel conflicts using its clear channel selection feature and fully realizes the advantages of channel binding, greatly enhancing wireless performance.

WPA / WPA2 Encryptions - Advanced Security
TL-WN881ND provides WPA/WPA2 encryptions that are created by the WI-FI Alliance industry group, promoting interpretabilities and security for WLAN, which can effectively and efficiently protect the wireless network.

Bundled CD for Easy Operation
TL-WN881ND comes with an installation CD that helps complete the software installation and setup the wireless network settings.
