Description Petr Novak 2017-07-19 17:55:51 UTC

Description of problem:
Mobile broadband connection fails to establish in Fedora 26 (upgraded from 25).

The connection worked as expected in previous F25.




How reproducible:


Steps to Reproduce:
1. Upgrade to F26 (e.g. from 25)
2. Connect (or create and connect) a mobile broadband connection via Network Manager
3. Attempt to connect


Actual results:


- The Gnome Network Manager UI returns to a non-connected state.

- mcli conn up uuid ..... shows "Unknown error"

- journalct (system log) gives more info:

- modem-broadband[ttyUSB1]: failed to connect modem: Serial command timed out


Expected results:

A connection to be established
Additional info:

- Modem does not respond to AT commands at /dev/ttyUSB1
- NetworkManager-wwan-1.8.0-6.fc26.x86_64 is installed
- ModemManager can see modem ok: Huawei ME906E port:ttyUSB1 type: GSM
