  1. Hello Brian,

    Great article.

    I’m currently still deciding which WiFi USB Adapter to get for Pen testing under Kali Linux 2019.3

    Do you by any means know if it’s better to get AWUS1900 over the AWUS036ACH or vice versa?

    I want to use it for monitor/injection but i read many contradicting posts (both recent and older posts) on the internet so hopefully you can give me some advice on which one to get for the aformentioned purposes?

    Best regards,

    1. Hi Copytright, thank you for leaving your comment.

      The Alfa 1900 has more power and support for dual band but in the other hand the 036 has more compatibility with Kali than the other one, so pretty much the only difference would be the price and the range each one has.

      So if you do not mind to spend a few more bucks, just go for the 1900.

      Hope that it helps.


  2. Hello again,

    So (if i get this right), you’re saying that the difference in compatibility between the two is neglectable and i’m better off with the slightly more expensive and newer model?
