4G Raspberry Pi HAT - MBIM Mode Setup on Windows

Introduction​

The Quectel 4G Raspberry Pi HAT supports internet connectivity on Windows by utilizing MBIM (Mobile Broadband Interface Model) mode. This mode enables Windows to recognize the 4G module as a native cellular modem, facilitating a stable and driver-supported network connection.

This guide will walk you through the necessary steps to configure your Quectel module in MBIM mode and connect it to the internet on Windows 10/11 systems.

MBIM Driver Download​

Once installed, you can verify driver installation by navigating to Computer Management → Device Manager. A successful installation will show devices under "Network Adapters" and "Ports (COM & LPT)" similar to the image below:

Configure MBIM Mode​

To switch the module to MBIM mode, you will need the QCOM Tool.

  1. Download and open the QCOM Tool.

  2. Connect your 4G HAT to your Windows PC via USB and power it on.

  3. In QCOM, send the following AT command to check the current USB mode:

    AT+QCFG="usbnet"?
    • If it returns anything other than "usbnet",2, skip this.

  4. To switch to MBIM mode, send:

    AT+QCFG="usbnet",2

  5. Then reboot 

    AT+CFUN=1,1
note

Sometimes you may experience the AT port not responding. In such cases, use the DM port instead.

Connect to Network​

Once configured in MBIM mode:

  • Windows should detect a Cellular Network Interface.
  • You can now manage and connect to networks directly from the Windows Network & Internet Settings.

Verify Network Configuration​

To verify if your PC has acquired a network connection via MBIM:

  1. Open Command Prompt.

  2. Run:

    ipconfig

    You should see an interface with an IP address under "Mobile Broadband Connection" or "Cellular".
