The USB Wireless Adapter connects your desktop or laptop to your home network using the IEEE 802.11n fast standard.This will allow you to transfer files up to 300 MBit / s, which will surely be appreciated by online gamers and HD video enthusiasts who can stream with your computer's adapter, for example, to a game console or multimedia center in your living room. Equally important is the security of the connection and therefore the adapter is equipped with a QSS button to quickly create a wireless network with security against unauthorized intrusion from the outside.

Long distance speed

The IEEE 802.11n standard, supported by the TP-LINK adapter and MIMO technology, is an excellent means of transmitting data without loss over long distances despite several 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 at even greater distances. This advantage will also be appreciated by online gaming players.

Stable connection

Forget about signal loss due to channel conflicts. CCA (Clear Channel Assessment) technology automatically prevents this condition, and 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) support allows you to set up network security almost instantly by just pressing a QSS button. The network will be secured with WPA2 encryption, which offers a much higher level of security than simpler WEP encryption. In addition to the benefits in terms of speed, you do not even have to remember any passwords at all !

Easy to install

First setting up and running the adapter is very easy with the included Easy Assistant CD attached.Step by step you will enter information and parameters. With everything, including wireless network setup or security, the program will help you. Even newcomers will not have to worry about how they should properly set the adapter.

It works the first time In Windows XP, I focused on utilities, but could be clearer. I was expecting a lower received signal level than the notebook, but it was finally about half.
