OpenWRT - Intel N5105 Router PC LTE/4G Module Install & Configuration (QMI Mode)

In this video, I will show you how to install & configure the 5G/4G/3G module in OpenWRT with ModemManager. For the hardware, I used the Intel N5105 2.5GbE Router PC and the Quectel EC25E module. Besides x86, the guide can be applied for most of the routers running OpenWrt, no matter it is ARM-based devices such as the NanoPi R6S, NanoPi R4S or MIPS-based devices such as the Xiaomi R3G, Xiaomi Router 4, etc. In order to use with ModemManager, it is recommended that the 4G module is working on the QMI USB mode. You can change the USB mode to QMI with AT+QCFG=“usbnet”,0 command (if you are using Quectel module).
