If he indicates finally connected permanently does not mean that, but now that I really can the Internet. Often the browser says then the connection can not be made and a short time later also Windows shows again is connected to the computer is not connected. Even if the connection is finally it is much worse than my previous, now almost 4 years old Asus Netbook. So show me the laptop while in my room at the desk a full reception on, but the transfer rate is extremely low compared to the netbook (both in the same place on my desk).
