300Mbps Wireless N PCI Adapter (TL-WN851ND)

What This Product Does
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.

* Comes with a Low Profile bracket included in the box

No problems

Got 1 in my Dad's PC and one in my Brothers. Work fine. Have reasonably good reception and Windows 7 has the drivers built in already. Been going fine for months now. (Please note: Not tried with Windows 8.)

No problems with the card, easy to install and set-up. Though, now coming to realise that the range of the card is next to nothing, as Kris said, my router is only a few meters below my room and the signal is very poor.

Additionally, the utility software that is an optional installation is, not bad, however I found it to be constantly attaining window focus (even though it was only running in the taskbar!) Quickly removed that.

I have no issue with TP-Link and have just purchased the TL-WDN4800, hoping to have better results with that.

Bought this a few days back to replace my OcUK Value 150Mbps card as it kept losing signal. Unfortunately this is exactly the same, if not worse. I am upstairs directly above my router (About 3 meters from computer to router, if that.) and I'm barely getting 60% signal and it sometimes drops out. Maybe it's my router.. unsure. Software is brill, easy to setup and works very well. Hope this helps anyone looking to buy.
