OpenWrt Networking on Raspberry Pi with CDC-ECM

This article will help you quickly take a Raspberry Pi and configure it as an Internet Router using OpenWrt software.

We focus on OpenWrt 22.03.6 software and Telit-Cinterion Cellular module hardware.

Internet connectivity is achieved using the medium performance CDC-ECM “Wireless Ethernet Adapter” method.

This uses cdc-acm / cdc-ecm drivers and Linux shell scripts (see AT Command AT^SWWAN) to start the interface.
