The adapter is easy to install and manage. With unmatched wireless performance, reception, and security protection, the TL-WN851ND is the best choice for easily adding or upgrading wireless connectivity to your desktop computer.

It has good anti-jamming capabilities, and it can also interoperate with other wireless (802.11b) products. The adapter supports WEP, WPA and WPA2 encryption to prevent outside intrusion and protect your personal information from being exposed.

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
Quick Security Setup
Compatible with Wi-Fi Protected Setup (WPS), the TL-WN851ND features a Quick Security Setup (QSS) function, which is ideal for creating a WPA encrypted connection to prevent outside intrusion, and meanwhile maximizes 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
WPA / WPA2 Encryptions - Advanced Security
As for the security of a 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
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
Wireless N - Speed & Range
MIMO (Multiple Input, Multiple Output antennas) technology 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

      Comments about TP-Link TL-WN851ND Wireless N PCI Adapter:

      I wanted to give my recent PC build wireless network capability. I didn't expected nothing too fancy for the price, but this card exceeded my expectations.

      Pretty quick and it actually works pretty well with Windows 10. Didn't even need to use the driver's disc it came with.

      Comments about TP-Link TL-WN851ND Wireless N PCI Adapter:

      Product comes with everything you need to install on a new machine but may give you issues in Windows 10 as the installatuon software is for older versions of Windows. Just let windows 10 install a driver automatically and it works great.
