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.

Alfa AWUS036ACH WiFi Speed Test 5GHz Band

All speed test were done to a Neatgear 802.11ax WiFi-6 router 10 feet away past a wall.

Speedtest.net was used for some basic results since my internet connection maxes out around 200-220Mbps.

It gave some impressive speeds at 213Mbps Download, and 21Mbps Upload.

Summary
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 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.

    Hello,

    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.

    Regards,
    Jas.

    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?

    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?
