Van Tech Corner ： OpenWRT – Install and Configure LTE modem in QMI mode – Quectel EC25 & Wallys DR4029
In this video, we are going to install the LTE/4G module on OpenWRT router and configure the modem to work in QMI mode. I am using the Quectel EC25-E LTE module and Wallys DR4029 router board. The router has a mini PCIe connector for LTE module but it is actually a USB 2.0. Because of this, the guide will also work with 3G/ LTE USB modem. At the same time, this guide can be applied for 3G (HSPA), 4G (LTE) and 5G module.
The steps is very easy: You just need to install the requires drivers and uqmi. When the modem is detected as cdc-wdm, go to Luci and create an interface, fill in the APN information and assign it to WAN firewall zone and you should be good to go.

As mentioned in the video, if you router doesn’t have a Mini-PCIe connector for modem, you can purchase a USB to Mini-PCIe with SIM card slot.
There are different modems works well with OpenWRT, for example: Sierra, SIMCom, Quectel; however, please check the supports band of the modem.
