Hi there!

want to share the GREAT fact that Kali support for Alfa Networks AWUS1900 (the most extreme until today) status is WORKING
just got the AWUS1900 in the mail today, ran a CLEAN install of 2017 release iso & "apt-get update && apt-get upgrade && apt-get dist-upgrade" rebooted, then ran the "apt-get install realtek-rtl88xxau-dkms" command, then REBOOT AGAIN (driver will loader)

and there we go.. [READY 2 GO] -- I personally cloned wifite-ng from my repo @ https://github.com/kimocoder/wifite-ng and in comparison to my "NetHunter" USB wifi dongle, the TL-WL722n this ALFA got more POWER under the hood !!

* ISSUES NOTICED:
- airmon-ng struggle to put it in monitor mode, therefor, do it manually with "ifconfig wlan# down && iwconfig wlan# mode monitor && ifconfig wlan# up"

Monitor / Injection: WORKING

Outputs:
