The Alfa AWUS036ACH, AWUS1900, and AWUS036AC can run with monitor mode and injection support on Kali Linux 2020.3. These products use the Realtek RTL8812AU and Realtek RTL8814AU chipsets respectively. But Github changed the driver package on October 9th 2020 with a change description of "Makefile: simplify DKMS install/removal" and so the install process is different than in past versions.
In this video we show how to download and install the driver.
We are the largest authorized Alfa Network distributor and brand partner, and a leading retailer and developer of WiFi & 4G products based in Gainesville, Florida.
