I updated my router from lede 17.0.1 to openwrt 23.05.5. Unfortunatelly I was not able to save any config file and package list. Now the router is updated but lost all the setting and no there is no more 4g modem. I need to set 4g modem, any help where to start? I'm very newbie. thanks in advance
at the moment I can see just 3 interfaces:
lan
wan
wan6
and 7 devices:
br-lan
eth0
lan1
lan2
lan2
lan4
wan
You have to reset your configuration from system/flash ops or failsafe mode
migration of config files works only one major version ahead.

You need to follow https://openwrt.org/docs/guide-user/network/wan/wwan/ltedongle
thanks a lot. I'll try to follow the guide. As far I can remember there was also a setting based on "mwan3" package on the original setup. Do you think the suggested guide can cover my double modem router? thanks
Yes, it will work, though historically mwan needs manual pre-install of iptables-nft and lots of steps to certainly avoid old fw engine sneaking in.
Multiple wans is a separate issue. Get a single wan with one modem working first. Then you can install mwan3 and set it up.
If you saved your old config you can open it (it is a tar archive) and examine the settings inside for guidance to rebuild the configuration. I don't think that mwan3 has changed much, though LTE certainly has.
I did following steps:
downloaded image from firmware selector:
https://firmware-selector.openwrt.org/?version=23.05.5&target=ramips%2Fmt7621&id=zbtlink_zbt-wg1602-v04-32m
added custom packages:
nano kmod-usb-net-cdc-mbim umbim luci-proto-mbim kmod-usb-serial-option picocom usb-modeswitch
rebooted from console
ls -l /dev/cdc*
gives following error: ls: /dev/cdc*: No such file or directory
Created a new interface: 4g
Type: MBIM Cellular
Modem device: /dev/cdc-wdm0
APN: ***
Firewall: wan-wan6
The created interface says: Error: Network device is not present
any help?
thanks
Your modem is in QMI mode now, not MBIM.You need to switch it to MBIM or follow instructions for QMI modems.
usb-modeswitch is not needed.
thanks I succefully set the new QMI interface:
Created a new interface: 4g
Type: QMI Cellular
Modem device: /dev/cdc-wdm0
APN: web
IPv4
Firewall: wan-wan6
I tested the modem throught these commands:
uqmi -d /dev/cdc-wdm0 --get-data-status
"connected"
uqmi -d /dev/cdc-wdm0 --get-signal-info
{
"type": "lte",
"rssi": -50,
"rsrq": -10,
"rsrp": -81,
"snr": 8.000000
}
How do I connect the router to internet?
thanks
It should be connected already. Show the output of the following:

See if you have a dynamic interface like 4g_4 or something like that and use its name.
For ping you can use wwan0 name instead.

IT WORKS!
thanks a lot for your assistance. Now I have to share internet to wifi and ethernet ports. There is a guide somewhere?
