The Alfa AWUS036ACH is a long range wireless USB adapter that is compatible with most any operating system, from Windows 10 to Linux.
It is a Dual Band 802.11ac WiFi dongle that works in both the 2.4Ghz and 5GHz ranges.
It is also a long range WiFi adapter with two 5dBi antennas that can swivel about.
I bought this adapter to see how well it performed with the results below.
Model: Alfa AWUS036ACH
Frequency: Dual Band 2.4GHz and 5GHz
Two 5dBi detachable antennas
Interface: USB 3.0 Micro-B
The package comes with the Adapter, Driver CD, Clips, Cable, Quick Start Guide, and two 5dBi Antennas.
It uses a USB 3.0 Micro-B Cable for fast transfer speeds.
While it is backward compatible with USB 2.0 it will work best with a USB 3.0 port.
Two 5dBi detachable antennas are attached which greatly improves a WiFi signal.
I plugged it in to a Laptop running Windows 10 Pro which automatically found the adapter with no need to install Drivers.
It shows it running the RTL8812AU Chipset.
WiFi Speed Test 5GHz Band
All speed test were done to a Neatgear Nighthawk 802.11ac router 10 feet away past a wall.
Speedtest.net was used for some basic results.
It gave some impressive speeds at 213Mbps Download, and 21Mbps Upload.
WiFi Speed Test 2.4 GHz Band
The same WiFi speed test was done on with the 2.4GHz frequency
Using the 2.4GHz Band with Wireless-N it gave 101Mbps Download, and 21Mbps Upload.
I plan to do much more testing with the Alfa AWUS036ACH and will update this post as I do.

The Alfa AWUS036ACH is a very good long range USB WiFi adapter with very good speeds.
If possible be sure to use a USB 3.0 port as to not bottleneck the transfer rate.
I am going to be doing much more testing with this adapter since it is known to be Kali Linux compatible and able to do Pen Testing.
Kali Linux announced it now comes with Driver support for RTL8812AU Chipset as of release 2017.1. Read Here for information.
This means it will be able to go into Monitor Mode and do Packet Injections.
Since it is a dual band 802.11ac device this will be the first Wireless-AC dongle able to do this.
As always be sure to read the reviews on Amazon, forums, or elsewhere to be sure a unit is a good fit for you.
Please suggest which is best with Kali linux, between Alfa AWUS036ACH and Alfa AWUS1900.
Also, I might add the tp link 24dbi parabolic antenna. Can you give advice on that?
Thank you for your input.
AWUS1900 for sure
You report that the Adapter is USB2 backward compatible, but works best with USB3. Which disadvantages are to be expected if the adapter is used on a USB2 Port?

On one hand; thank you, thank you, thank you for this information, on the other; couldn’t you have put this near the top of the article instead of the summary?
