Hi,

I tried again with mbim, because its a branded huawei mu736.
Same results as before:
ifconfig shows errors and I don't receive any bytes.

option 1-3:2.2: GSM modem (1-port) converter detected
usb 1-3: GSM modem (1-port) converter now attached to ttyUSB0
usbcore: registered new interface driver cdc_ncm

Has someone any ideas?
should we go on with option, or mbim?
could it help to disable ipv6?
