I successfully installed OpenWRT ( 22.03.3 r20028-43d71ad93e ) on this router.
I configured the WIFI and local DHCP, my devices can connect on the router, but I have no any internet connection.
I don't find how to configure 4G / LTE interface.
I found some informations on internet, but it doesn't match with my v4 (I saw on a video on youtube that the LTE is seen as USB, but I don't have any USB interface). Please, do you have any idea how to configure LTE ?
Check if APN and PDP Type settings are correct.
Then check if gateway and DNS settings are ticked on the Advanced Settings page.
You don't need to add anything "in the firewall", you only need to select the firewall zone in the interface configuration.
I would start from running some basic checks like network registration, signal level, connection state, etc.
You can either use various uqmi --get-... commands as shown in OpenWrt docs or standard AT commands from a terminal, for that you can install picocom package in a standard way. Make sure you have /dev/ttyUSB* interfaces available, overwise you will need to install the appropriate drivers.
You may need to disable DHCP in QMI interface configuration, but I'm not 100% certain that is critical for your modem. Simply add option dhcp 0 in QMI interface section in /etc/config/network
I am struggling - almost the same path as Jey went trough - with the MR6400 LTE modem install.
I have an error message **Error:** Unknown error (PIN_STATUS_FAILED)' as the OWRT restarts after save&apply. I have set no PIN requirement on this SIM card, nevertheless I was tried with the PIN as well, no difference...
Can you help me please, what could be wrong? Thank you
