LTE connection setup⚓︎

Warning

This manual is intended to be used with the modem we provide in retail as a part of the LTE kit. In case you use any other modem ePCIe card this might not apply.

Prerequisties⚓︎

Support packages and drivers⚓︎

For the modem to work, we first need to install drivers and utilities.

Component Description
kmod-usb-net-qmi-wwan QMI WWAN driver for Qualcomm MSM based 3G and LTE modems.
libqmi Helper library talk to QMI enabled modems. Add qmi-utils for extra utilities.
uqmi Command line tool for controlling mobile broadband modems using the QMI-protocol.

We can do it simply in CLI (via ssh) using the following commands:

opkg update
opkg install kmod-usb-net-qmi-wwan libqmi uqmi luci-proto-qmi

UCi setup⚓︎

First we need to determine if the settings are on place.

uci show network.LTE

Standard settings (common for most configurations)

network.LTE=interface
network.LTE.pincode='0000'
network.LTE.proto='qmi'
network.LTE.device='/dev/cdc-wdm0'
network.LTE.auth='none'
network.LTE.apn='internet'
network.LTE.pdptype='ipv4'

The setting network.LTE.apn depends on your mobile network operator.

Footnote⚓︎

Some mobile operators require additional authentication setup with

  • auth type (NONE/PAP/CHAP)
  • username
  • password
