I meant one thing about this key. I use linux for work and making me a new configue I was looking for a wifi connection for Ubuntu. Looking at the table of correspondence I could see that this was the right key configurations and so I thought for the price that had to be tested. I used it on Ubuntu 11 and 12 now, and it is automatically recognized not even need to install anything at all. I am delighted because I could make my installations without problems and above all the updates. I use it all the time and no problems so far. The rate is very good and she especially takes no place. I recommend the course for all recent Windows systems but also because it works seamlessly with Ubuntu.
