Switch to standard MBIM or QMI driver and re-test.

If I switch to satandard driver qmi_wwan I do not get /dev/cdc-wdm0.
Thank you for your time!

There is no “usbnet” for af+qcfg=?
I have read a claim where it should be available at “usbnet”,0, and it would require a newer firmware than my BG95-M1.

I think this is the first time you mentioned the model name, so forget about QMI. ECM seems to be the only choice.
Check AT+QCFGEXT=? instead.

[Frode]

You are right, I did not mention the model

AT+QGMR

Hi Frode,

I am facing very similar issue, did you get any solution ?
