I purchase this USB with external antena. In win7 works great - I can connect to AP 1.2miles from where I am. My main AP is about 50feet away. My laptop ia Gateway NE71B with Intel wireless. I downloaded WICD and remove Gnome network manager. That way I can control the wifi device. My build in wireless is way faster that the Alpha - even with external antena. All full bars, but *** dragging speed. I get 3bard with my internal and have better speed. Does any one know of how to fix it?. Even that the internal have greater speed, it is dropping signal, because of obstacles on the way. Just reinstalled Kali and can not get updates - get stuck half a way and quit. Web browser slow as ****.
