Steffen Neumann, Do you mind sharing step by step what you had to do? I'm on 17.10 and have the same Huawei ME936, no matter what I did (including adding the rule suggested by Philip Hufnagl) doesn't seem to fix the issue.
Windows 10 has absolutely no issues with it. It just works out of the box. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to modemmanager in Ubuntu. https://bugs.launchpad.net/bugs/1735981 Title: Huawei ME936 mobile broadband can't connect Status in modemmanager package in Ubuntu: Confirmed Bug description: Hi, I have an Acer Travelmate P648 with a Huawei ME936 internal USB mobile broadband card, and can't connect. This didn't work in 17.04, and still does not work in 17.10. The USB device is successfully connected, ModemManager gets as far as "Simple connect state (8/8): All done" During the setup ModemManager complains with "Couldn't find associated cdc-wdm port for 'net/wwp0s20f0u9c2'" DHCP tries to get a configuration, but " dhcp4 (wwp0s20f0u9c2): request timed out". IP6 is set to "automatically" in the network settings for this configuration. and finally connection fails with "device (ttyUSB0): state change: ip-config -> failed (reason 'ip-config-unavailable', internal state 'managed')" I checked that there are enough credits left in my account with the provider. Any ideas what else to check ?
