Important Special Reminder for Linux / Kali / LibreELEC Users
This WiFi adapter is equipped with genuine MediaTek MT7612U chip, with built-in driver storage partition.
✅ Windows 7/8/10/11: Plug and play directly, it will automatically switch to WiFi mode without extra operations.
⚠️ Linux System Special Situation:
When you first plug in the adapter, Linux will identify it as a USB flash drive (Hardware ID: 0e8d:2870), and the WiFi function is locked.
This is not a false chip label! You need to run the specified command to switch the hardware to wireless mode, then load the driver to use WiFi normally.
The built-in storage partition only stores Windows drivers; Windows can auto skip storage mode, while Linux has no native auto-switch function.
After successful switching, the hardware ID will change to 0e8d:7612, and the wireless network card interface wlan will appear.
Complete Operation Steps for Linux System
Step 1 Install the mode switching tool
Copy the following two lines of code and run them in the terminal:
If you don’t want to input commands manually after each reboot, run this script once to realize automatic startup switching:
cat > /storage/.config/autostart.sh << 'EOF' #!/bin/sh sleep 5 /usr/sbin/usb_modeswitch -K -W -v 0x0e8d -p 0x2870 for i in $(seq 1 10); do lsusb | grep -q "0e8d:7612" && break sleep 1 done systemctl restart connman EOF chmod +x /storage/.config/autostart.sh
Q1: After plugging in the card, only USB storage is displayed, no wireless network card?
A1: This is the factory default state of the network card, which is normal. Linux system cannot automatically convert hardware types. You must complete Step 1 and Step 2 above to unlock the WiFi function. The real chip is MT7612U, and the hardware ID will change to 0e8d:7612 after switching.
Q2: Mode switched successfully, but cannot find any 5GHz WiFi signals?
A2: This issue is caused by missing MediaTek wireless firmware. Run this installation command in terminal:
Re-run sudo modprobe mt76x2u to reload driver, then 5GHz networks will show up.
Q3: Does this adapter support monitor mode for WiFi capture & analysis?
A3: Yes. Finish all mode switching and driver loading steps first, then use airmon-ng tool to open monitor mode.
Before placing an order, please note that there are 2 models in the link, but they are all MT7612U chips, but their appearance is different.
