ALFA AWUS036AXML Driver Install Guide for China: Kali Linux, Ubuntu, Debian & Raspberry Pi

The AWUS036AXML is ALFA’s WiFi 6E flagship — a tri-band USB-C adapter covering 2.4 GHz, 5 GHz, and the uncongested 6 GHz band. Its MT7921AUN chip uses the mt7921u driver, built into the Linux kernel since version 5.18. On Ubuntu 24.04 and Kali 2025 it is plug-and-play once the firmware package is installed from a domestic mirror. This guide covers the full setup — firmware, driver verification, monitor mode, packet injection, and VIF — without touching GitHub.

Make sure you have these ready:

Before You Start

#

Make sure you have these ready:

1. ALFA AWUS036AXML adapter and USB-C cable
2. A powered USB hub — required if you are on Raspberry Pi
3. Active internet connection to reach domestic mirrors

Plug in the adapter, then confirm your system sees it:

lsusb

Look for this in the output:

Bus 001 Device 003: ID 0e8d:7961 MediaTek Inc.

If you see 0e8d:7961, the adapter is detected. Move to your OS section below.

If you do not see it, try a different USB-C port or cable, then run lsusb again.

Choose Your Operating System

#

Jump to the right section for your OS:

• Kali Linux
• Ubuntu 22.04 / 24.04
• Debian
• Raspberry Pi 4B / 5

Already installed? Skip to:

• Enable Monitor Mode
• Test Packet Injection
• Virtual Interface (VIF)
• VM USB Passthrough

Kali Linux

#

The MT7921AUN driver is already in the Kali kernel. All you need is the MediaTek firmware package, available from domestic mirrors.

Step 1: Switch to China Mirror

#

Open your sources list in the terminal.

sudo nano /etc/apt/sources.list

Delete whatever is there, then paste this line:

deb http://mirrors.ustc.edu.cn/kali kali-rolling main contrib non-free non-free-firmware

Save: press Ctrl+O, then Enter, then Ctrl+X to exit. Refresh the package index.

sudo apt update

Backup mirror: If 中科大 (USTC) is slow, use 清华 (Tsinghua) instead: deb https://mirrors.tuna.tsinghua.edu.cn/kali kali-rolling main contrib non-free non-free-firmware

Step 2: Install Firmware

#

The MT7921AUN requires firmware blobs from firmware-misc-nonfree and linux-firmware. Without them the driver loads but the adapter fails to initialise.

sudo apt install -y linux-firmware firmware-misc-nonfree
sudo reboot

Step 3: Verify the Driver

#

After reboot, plug in the adapter and check.

lsmod | grep mt7921

You should see mt7921u in the output. Then confirm a wireless interface appeared.

iwconfig

Look for wlan0 or wlan1. If it appears, the driver is working.

Step 4: Enable Monitor Mode

#

Check the interface name first.

iwconfig

Use the name you see (e.g. wlan1). Kill interfering processes, then switch to monitor mode.

sudo airmon-ng check kill
sudo ip link set wlan1 down
sudo iw dev wlan1 set type monitor
sudo ip link set wlan1 up

Confirm the switch.

iwconfig

Look for Mode:Monitor on the interface.

Step 5: Test Packet Injection

#

sudo aireplay-ng --test wlan1

A successful result:

Trying broadcast probe requests...
Injection is working!
Found 1 AP

If it fails, reboot and try again.

Ubuntu 22.04 / 24.04

#

Ubuntu 24.04 (Noble) — kernel 6.8, plug-and-play

#

Ubuntu 24.04 ships kernel 6.8, which includes the MT7921AUN driver natively.

Step 1: Switch to China Mirror

#

sudo nano /etc/apt/sources.list.d/ubuntu.sources

Delete everything and paste:

Types: deb
URIs: http://mirrors.aliyun.com/ubuntu/
Suites: noble noble-updates noble-security
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

Save with Ctrl+O, then exit with Ctrl+X.

sudo apt update

Step 2: Install Firmware

#

sudo apt install -y linux-firmware
sudo reboot

Step 3: Verify and Enable Monitor Mode

#

After reboot, run lsmod | grep mt7921 to confirm the driver loaded, then follow the Kali monitor mode steps above (Step 4).

Ubuntu 22.04 (Jammy) — HWE kernel required

#

Ubuntu 22.04 ships kernel 5.15. The MT7921AUN driver requires kernel ≥ 5.18. Install the HWE kernel first.

Step 1: Switch to China Mirror

#

sudo nano /etc/apt/sources.list

Replace all lines with:

deb http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse

Save and exit (Ctrl+O, then Ctrl+X).

sudo apt update

Step 2: Install HWE Kernel

#

sudo apt install -y linux-generic-hwe-22.04
sudo reboot

After reboot, confirm kernel version:

uname -r

You should see 5.19 or higher. Then install firmware and enable monitor mode as above.

Step 3: Install Firmware

#

sudo apt install -y linux-firmware
sudo reboot

Debian

#

Step 1: Switch to China Mirror

#

sudo nano /etc/apt/sources.list

Delete everything and paste (Debian 12 Bookworm):

deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm main contrib non-free non-free-firmware
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm-updates main contrib non-free non-free-firmware
deb https://mirrors.tuna.tsinghua.edu.cn/debian-security bookworm-security main contrib non-free non-free-firmware

Save with Ctrl+O, then exit with Ctrl+X.

sudo apt update

Step 2: Install Firmware

#

Debian 12 Bookworm ships kernel 6.1 — compatible with MT7921AUN.

sudo apt install -y firmware-misc-nonfree linux-firmware
sudo reboot

Step 3: Verify and Enable Monitor Mode

#

lsmod | grep mt7921
sudo airmon-ng check kill
sudo ip link set wlan1 down
sudo iw dev wlan1 set type monitor
sudo ip link set wlan1 up
iwconfig

Step 4: Test Packet Injection

#

sudo aireplay-ng --test wlan1

Injection is working! confirms the adapter is fully operational.

Raspberry Pi 4B / 5

#

The AWUS036AXML draws up to 2.7W under load. Always use a powered USB hub on Raspberry Pi.

Step 1: Download Kali Linux ARM64 Image

#

Official page: https://www.kali.org/get-kali/#kali-arm

Pick Raspberry Pi 4 (64-bit) or Raspberry Pi 5 (64-bit) — 64-bit is required.

China mirror: https://repo.huaweicloud.com/kali-images/ — browse to the latest release folder and download the ARM64 image.

Step 2: Flash to MicroSD

#

lsblk
# Replace /dev/sdX with your actual SD card
sudo dd if=kali-linux-2025.1-raspberry-pi-arm64.img of=/dev/sdX bs=4M status=progress conv=fsync
sync

Default credentials: kali / kali.

Step 3: Switch to China Mirror and Install Firmware

#

sudo nano /etc/apt/sources.list

Replace with:

deb http://mirrors.ustc.edu.cn/kali kali-rolling main contrib non-free non-free-firmware

Then:

sudo apt update && sudo apt full-upgrade -y
sudo apt install -y linux-firmware firmware-misc-nonfree
sudo reboot

Step 4: Verify Driver

#

lsmod | grep mt7921

mt7921u should appear.

Step 5: Enable Monitor Mode

#

On a Pi with built-in Wi-Fi, the AWUS036AXML shows up as wlan1.

iwconfig
sudo airmon-ng check kill
sudo ip link set wlan1 down
sudo iw dev wlan1 set type monitor
sudo ip link set wlan1 up
iwconfig

Step 6: Test Packet Injection

#

sudo aireplay-ng --test wlan1

Virtual Machine USB Passthrough

#

VirtualBox

#

1. Power off the VM. Go to Settings → USB.
2. Enable USB 3.0 (xHCI) Controller.
3. Click + to add a USB filter.
4. Select: MediaTek Inc. (ID: 0e8d:7961).
5. Start the VM — the adapter appears inside Kali.

Run lsusb in the VM to confirm 0e8d:7961, then follow the Kali steps above.

VMware Fusion (macOS) / VMware Workstation (Windows)

#

1. Start the VM.
2. Menu: Virtual Machine → USB & Bluetooth.
3. Find MediaTek MT7921AUN and click Connect.
4. Run lsusb in the VM to confirm, then follow the Kali steps above.

Virtual Interface (VIF)

#

The MT7921AUN has full kernel-native VIF support. You can run a monitor interface and a managed interface on the same adapter simultaneously — no patches required.

Create a Monitor Interface Alongside Managed Mode

#

sudo iw dev wlan0 interface add mon0 type monitor
sudo ip link set mon0 up
iwconfig

You should see both wlan0 (managed) and mon0 (monitor) active at the same time.

Monitor While Staying Connected

#

sudo airodump-ng mon0

wlan0 stays associated while mon0 captures everything in range.

Fake AP + Monitor

#

sudo iw dev wlan0 interface add ap0 type __ap
sudo iw dev wlan0 interface add mon0 type monitor
sudo ip link set ap0 up
sudo ip link set mon0 up
iwconfig

Note on hostapd: Full AP operation requires configuring hostapd. The steps above confirm the adapter can create the interface — actual AP configuration is a separate topic.
