Wireless N PCI Adapter TL-WN851ND allows you to connect a desktop computer to a wireless network and access high-speed Internet connection. Comply with IEEE 802.11n, they provide wireless speed up to 300Mbps, which is beneficial for the online gaming or even HD video streaming.

Wireless N - Speed & Range
MIMO (multiple input, multiple output antennas) technology, it shows more excellent abilities of mitigating data loss over long distances and through obstacles in a small office or a large apartment, even in a steel-and-concrete building. Above all, you could easily pick up the wireless network during long-distance connection where legacy 11g products may not!

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 enhanced the wireless performance.

WPA / WPA2 Encryptions - Advanced Security
As for the security of WI-FI connection, WEP encryption has been no longer the strongest and safest guards for outside intrusions. TL-WN851ND provides WPA/WPA2 encryptions that are created by the WI-FI Alliance industry group, promoting interpretabilities and security for WLAN, which could effectively and efficiently protect the wireless network.

Quick Security Setup
Compatible with WI-FI Protected Setup™ (WPS), TL-WN851ND features 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!

Bundled CD for Easy Operation
TL-WN851ND comes with a CD with utility that helps you complete the software installation and wireless network settings, including security configurations and wireless connection, which is convenient for users, even for novice users.

5* Excellent device

This is a very good product. I was initially worried as I ordered PCI Express version of this but had to return it due to my free PCIe slot being blocked by massive graphic card. I thought it would work less efficiently on older PCI link but I couldn't be more wrong! Coupled with TP-Link 300 Mbps Wireless N USB modem router TD-W8968 it delivers my top contracted speed 20 Mbps without a problem (although I only use ruter part of it as I have to relay on Virin Media modem). It's fairly easy to install (I had router installed first) and serves my PC desktop very well. The speed of connection is THE SAME as on ethernet cable!

I made the mistake of ASSUMING compatibility with Windows 8.

Installing made OS freeze several times. It was more stable once a connection was established. It still randomly froze and required rebooting.

TP-LINK do not yet support the WN851ND on Windows 8. Their website lists the adapters currently supporting windows 8; this one's listed as "Coming soon"

Here's a workaround:

1) Download the latest Drivers. Its a zip, you need to extract
2) Uninstall current drivers
3) Search for Troubleshooting, using Charms bar, look in Settings
4) Click Troubleshooting
5) Click "Run programs made for previous versions of Windows", click Next
6) Select "Not Listed", click Next
7) Click Browse and navigate to the Driver
8) Click next, click Troubleshoot program
9) Check "The program worked in earlier versions of Windows but won't install or run now" box, click next
10) Select Window 7, click Next
11) Complete Wizard

Works pretty well now!

(Note: this method didn't work with the utility software)
