TP-Link MR6400 - SIM Interface & configuration

Hello,

I have a TP-Link MR6400 v2.
I installed the open wrt factory image via tftp boot and afterwards the open wrt sysupgrade.
Then I also installed LUCI.

I have a Sim Card and want to configure the SIM Interface. But i can't find a way to do it in the LUCI GUI.
I checked the cofiguration file aswell but I am not sure how to configure it.

In some guidelines i found that the SIM module is accessable via 192.168.0.1 but that didn't work for me.

I found the guild below but it seems for a dongle / usb con.
https://wiki.openwrt.org/doc/recipes/ltedongle

Below also the dmesg:
(in the highlighted line there seem to be a GSM)
(also below the output from cat /sys/kernel/debug/usb/devices )

Incase anyone could guide me in the right direction or has any tips i would appreciate it!
Thanks a lot for your time!

BusyBox v1.28.4 () built-in shell (ash)

had exactly the same problem.
the rndis intertace is accessible vie adb shell and it has ip adrress 192.168.0.1 but the web interface to configure the gsm connection is not available and I have no idea on how to proceed. Right now I reverted to the original firmware.

Create a Portforward to access to webgui from usb0 modem!

IPv4-tcp, udp

HI,
Did you find a solution to thi?. I'm still blocked when trying to access 192.168.0.1/login.html
