I have a TL-WN721N Wireless USB Adapter and it has Atheros AR9271 driver version. Is it possible to send packets and set the mode to monitor with this adapter chipset? I read on a post and it said this:

Atheros AR9271: The Alfa AWUS036NHA is my favorite long-range network adapter and the standard by which I judge other long-range adapters. It's stable, fast, and a well-supported b/g/n wireless network adapter. There's also the TP-Link TL-WN722N, a favorite for newbies and experienced hackers alike. It's a compact b/g/n adapter that has one of the cheapest prices but boasts surprisingly impressive performance. That being said, only v1 will work with Kali Linux since v2 uses a different chipset.

I don't know if he referred to the driver version or chipset version. I can't find the information about the version of my chipset but the driver Atheros AR9271 has the version

Also when I run iwconfig wifi0 mode monitor it shows this error message:

Error for wireless request "Set Mode" (8B06) :
    SET failed on device wifi0 ; Invalid argument.

And when I run sudo airmon-ng start wifi0 it just gives me this and doesn't list any networks:

PHY     Interface       Driver          Chipset

I am using a Kali Linux subsystem on my Windows 10 OS. Maybe that can be a problem?

  1. You've hit the nail on the head: Windows Subsystem for Linux: It's good to muck around in bash and use most of the GNU tools, but when you need deeper access into the system, it will not provide that functionality as per the Micro$oft WSL about section

    The Windows Subsystem for Linux lets developers run GNU/Linux environment -- including most command-line tools, utilities, and applications -- directly on Windows, unmodified, without the overhead of a virtual machine.

    (Emphasis mine)

    because the WSL doesn't even contain a Linux kernel!

  2. As per the Kali Linux Docs section:

    1. Getting Started(4)
    2. Kali Linux Live(3)
    3. Installing Kali Linux(9)

    Kali is meant to be run live (Chapter 2) before you even try the next chapter on installing it on bare metal or (heaven forbid) dual booting it with Windows.

Note: No, a Kali VM is not a good substitute for booting it live from a USB Stick: You'll be running into the same kind of issues as running under WSL.

    As per Fabby's answer: WSL is not Linux - do not even think of doing low-level operations there. Nevertheless, I advise seeing what hw supports monitor mode before buying it. There are also databases out there for that, no need for asking here for each specific chipset. – Rui F Ribeiro Jan 23 '19 at 12:06
