im a real noob with Linux but i really wanna understand and learn it. I bought a Dell with preinstalled Ubuntu 16.04 and bought a USB wifi named ALFA AWUS036NHR version 2. I got a CD-rom with the drivers but i dont understand how i install them with Linux, that is how hard core noob i am. And the problem is that wifi works for like 3-4 minutes then it drops and i have to disconect and reconect to get it to work again 3-4 minutes. What can i do guys? really need you help!
