Hello, does anybody of you have the HUAWEI UMTS Modem MU736 running with Tumbleweed or Leap? It used to work flawlessly, but since some months I can't use it anymore.
Besides that ModemManager supports this model, I cannot find much useful information on the Internet, too.
Networkmanager detects it, but fails to set up a connection.
Since your modem reports the signal quality it basically works but do you see any errors from the kernel? While booting or connection?
[...] When NM tries to connect, "journalctl -f" brings up this error messages:
What do NM and MM say when they initialize your modem? Any errors? # journalctl -u NetworkManager -u ModemManager --this-boot

Well, that is not a very helpful warning. See https://wiki.gnome.org/Projects/NetworkManager/Debugging#Debugging_NetworkMa... These logs will contain much sensitive information, so I fear you have to figure out the important parts by yourself.
I tried several changes to udev files, did some work with usb_modeswitch but nothing helped. I attached the output of mmcli, lsusb and usb_modeswitch below - any help appreciated. [...]
I wonder why your modem uses only the option1 driver from the option kernel module and no cdc_*. Do you have old log files to confirm that it has ever been working with this driver? Maybe it used the qcserial kernel module before? Then you could try to blacklist the option kernel module.
