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

We focus on OpenWrt 21.02.3 software and Thales IoT 5G, 4G, and 3G Cellular module hardware MV31-W.
Note that only the newest Raspberry Pi 4 and above will offer true multi-100Mb/s throughput.

Internet connectivity is achieved using the Qualcomm MSM Interface (QMI) in user **** - with qmi_wwan drivers - all core protocol logic is in user-space processes.

Scripts are provided.
