I am a complete noob to this forum so bear with me here.
I bought the Alfa Wireless AWUS036AC, in the hope of good Linux compatability but it has been anything but compatible. I was hoping for some advice on how to fix it.
Firstly, straight out of the box, it doesn't work. Understandable as this supports 5Ghz and my previous adapter didn't as well as (maybe) a different type of chipset. BTW this Alfa adapter has a RTL8812AU chip set but I have read somewhere that the RTL8821AU and my chipset are interchangeable but perhaps not from a reliable source.
Secondly, it wasn't being recognised as a wlan0 device and doing iwconfig brought back only eth0 and lo, which would lead me to believe that it is a driver issue.
Thirdly, drivers. Alfa are not very good at instructions and following them got me nowhere (unless I read them wrong, (entirely likely))
