TP-Link TL-WN821N

The USB Wireless Adapter connects your desktop or laptop to your home network using the fast IEEE 802.11n standard. This will allow you to transfer files at speeds of up to 300Mbit/s, which will surely be appreciated by online gamers and video enthusiasts. HD video can be streamed via the adapter to a game console or multimedia center in your living room. Of course, security is also an important part of the device, and that's why it is equipped with a QSS button which quickly create a wireless network with security against unauthorized intrusion from the outside.
 

Top speed even at long distance

The support of IEEE 802.11n standard and MIMO technology makes the adapter an excellent means of transmitting data without loss over long distances. The signal is strong enough to travel through common obstacles in a small office or in a large room, even in buildings with steel and concrete structures. All demanding operations such as HD video streaming or VoIP telephony will not be a problem even at long distances. This advantage will also be appreciated by online gamers.

Stable connection

 
Forget about signal interruptions due to channel conflicts. CCA technology (Clear Channel Assessment) automatically prevents these events so you can enjoy uninterrupted, stable, and fast transmission without having to interfere with the network.

Secure connection

Secure your network in a simple way. WPS (Wi-Fi Protected Setup) allows you to set up network security almost instantly by just pressing the QSS button. The network will be automatically secured with WPA2 encryption, which offers a much higher level of security than the simpler WEP encryption. Not only is the setup almost instantaneous, you also do not have to remember any passwords!

User-friendly installation

Setting up the adapter is very easy with the attached Easy Assistant CD. The program will guide you step by step through entering various information and parameters, and will help you with everything, including wireless network setup or security settings. Even beginner users will be able to set everything up without spending hours looking through the manual.
