  • Can you confirm that the connection is not as stable or fast as on Windows? Ubuntu only gives you all signal bars if your connection is pretty awesome. It's a rating, not a physical fact. There are of course possibilities to test a connection in many ways. Could you please click on the wifi icon on the top right and choose "connection information" or similar (the second from the bottom) and paste the speed (mine is currently 24 Mb/s) into your Question? It gives you (and us) a rough idea of how fast/good the connection is. – verpfeilt Aug 7 '13 at 20:31

With this and I was able to speed 150 mb, all bars, and slow dissolves (in ubuntu 12.04.4 probe that is where I get a serious error if the adapter is connected before starting session, ubuntu freezes on that ground connecting the adapter only when session starts.)

This is the solution installed ndiswrapper, free driver add to the blacklist when ndiswrapper is installed just install the supplied driver pt-link.

To install the ndiswrapper is complicated if you have ubuntu 12.04, 12.10 and 13.04 that you will need install as the new one is not in center WILL NEED ubuntu download and install the packages you need are 4 or 5 Find them and download here packages.ubuntu.com creeo if you have ubuntu 13.10 this solved the problem this is not necessary.
