RNDIS on 4G LTE Raspberry pi HAT Windows
Introduction
RNDIS (Remote Network Driver Interface Specification) is a Microsoft protocol that enables USB devices to emulate network adapters, allowing them to provide internet or network access to a Windows PC via a USB connection. In Windows, installing the correct RNDIS driver is essential for devices like Quectel modules to function as virtual Ethernet interfaces. Once installed, the driver allows the PC to recognize the device as a network adapter, enabling internet sharing or local network communication. This process is especially common in cellular modules that provide internet connectivity over USB.

You can check the installation result through Computer Management → Device Manager. The "Device
Manager" interface after a successful driver installation is shown below.
Configure to RNDIS Mode
To configure RNDIS mode, use the QCOM tool and follow these steps:
- Enter and send the following command on QCOM tool:
AT+QCFG="usbnet"? - If the response does not show AT+QCFG="usbnet",3, manually set it to RNDIS mode by sending:
AT+QCFG="usbnet",3
Connect with Network
You should see a network interface (e.g., Network X) indicating the connection.
You can verify the new RNDIS configuration using the ipconfig command.
