            • Some People Have Chipset Issues

            alfa-awus051nh-300-mbps-5-8ghz-2-4ghz-wireless-b-g-n-dual-band-1103-06-tunglt3Most older USB WiFi Adapters that have worked well with Kali Linux or Backtrack don’t support the 5 GHz range which most routers support now. As dual band routers gain popularity in homes and offices, the
            Alfa AWUS051NH WiFi Adapter filled a gap by supporting both the 2.4 GHz and 5 GHz range for the 802.11n standard. The
            Alfa AWUS051NH that uses the Ralink RT2870 / 3070 chipset and works with both 2.4 GHz and 5 GHz frequencies.

            If you’ve found this review, you probably know that Kali Linux is a distro that is mostly used for penetration testing. The Alfa AWUS051NH WiFi adapter works well with packet capturing as well as packet injection. You can use this adapter with a standalone Kali Linux install, or as a virtual machine in VMware Workstation or Virtualbox.

            802.11ac Support

            One downside is that it does not support the newer 802.11ac protocol. Wireless N or 802.11n is the only 802.11 standard that works in both the 2.4 and 5 GHz range, while 802.11ac only works in 5 GHz and the old 802.11g works only in the 2.4 GHz range. As of this writing, I have not found a reliable Kali compatible 802.11ac adapter. It’ll be a while before homes and businesses only use 802.11ac though, and most will still have 802.11n enabled.

            Chipset

            I’ve seen some discussions regarding the chipset of the Alfa AWUS051NH WiFi adapter. The one I received (the one linked in the article through Amazon) came with the Ralink 2870/3070 chipset and works very well with Kali Linux.

            Run the lsusb command to see the correct chipset then load the correct chipset with rmmod and modprobe commands if there is a problem.
