I build latest 19.07.7 for my ZTB WE-826 and after I applied this tutorial. After adding the LTE interface it craetes itself the Virtual dynamic interface and immediately after I had internet connection.
All works like a sharm but after the first reboot I loose the Virtual dynamic interface and there is no way to rebuild it. I take a look on /etc/config/network and there is nothing about Virtual dynamic interface, probably this is why I lost it on first reboot?
Did you add the new interface device? It tells you how to add a wwan interface to use it.
Sure, as I wrote I added the LTE interface (QMI Cellular).
None know how can I add this Virtual dynamic interface?
The fact that it works directly after setup but not after a reboot hints at a problem with the LTE connection on boot. Maybe there is a race condition, or some other issue that prevents your dongle from connecting.
The "Virtual dynamic interface" is automatically spawned once the underlying wwan interface is brought up successfully. Try restarting the wwan interface via LuCI and see if that causes the virtual sub interface to appear.
This is interesting, I can try to set a higher modem init timeout.
I have the same problem, has it been resolved? What helped?
The DHCP client is not always necessary.
Switch the modem to MBIM (you have RG500Q, right?) and configure the interface as shown in the wiki:
https://openwrt.org/docs/guide-user/network/wan/wwan/ltedongle#configuration
Then, if you have any issues, post the relevant fragment of your system log. No pictures, please.
YES end aw1000
the modem is still waiting for the pin, but the sim card has no pin
Check what you missed from the instructions and post the requested log.
