mariusl try to use address ttyUSB2 instead of cdc_wm0. Could you also post the output when you click the network button

I made the changes as you suggested and this is what I get:

mariusl Im not familliar with K3765, nor is it listed in supported modems but as long as modeminformation is able to withdraw all the neccessary information this should work.

It seems like the modem is not switched properly from storage devices to modem. You need to have either wwan0 or ppp0 interface which you doesn't have.

I can login to your RPI and have a look if you want?
Please send me a PM on Discord if you want,. https://discord.gg/xwqMTXh

Sorry I dont seem to get the code inclusion of the forum right. Is there a special way to do it?

mariusl

We can do that after the new year. I am taking a day or two off now.
