Description of problem: Since F23 (or before F22 see Bug 1234727) it is not possible to plugin an usb modem and connect to the broadband internet. In F21 it worked without any problem.

Steps to Reproduce: 1. Join user to the dialout group 2. Plugin the usb modem. A PIN request dialog pops up 3. Enter valid TIN 4. USB-Modem accepts tin and led color changes from red to green 5. open the network manager and fill in the well known parameters 6. push connect button 7. the taskbar "donut" for network setup rotates and sometimes disappear. 8. no connection 9. open a shell and call $journalctl -e -a Actual results: no connection an some errors in journalctl Expected results: established connection Additional info: There seems to be an issue with the ttyUSB1 reported by the firewalld: >> Jan 11 20:57:21 chrissyboy.fritz.box /firewalld[1079]: 2016-01-11 20:57:21 ERROR: UNKNOWN_INTERFACE: 'ttyUSB1' is not in any zone see output of journalctl (as root) Jan 11 20:57:14 chrissyboy.fritz.box ModemManager[1086]: <info> Simple connect started...

Dear friends, other network UI also fail. It is NOT Kde realted, Gnome and Ciannamon also failed. Look at the error with the ttyUSB, the error depends on the unavailability of that device. This is not KDE related, cause the UI part only triggers the Network Manager backend, and it is the NM-backend part that fails. The problem may depend on the firewalld, that tells me, >> Jan 11 20:57:21 chrissyboy.fritz.box /firewalld[1079]: 2016-01-11 20:57:21 ERROR: UNKNOWN_INTERFACE: 'ttyUSB1' is not in any zone that the device it not in any zone. Iff i disable the firewall, the problem is still there. Some it may be also possible, that you overseen a setting, that cause the weired firewalld message. Send me an message iff i can help you!

I face the same problem. The problem is that the modem works only if it is connected to ttyUSB0. The ports ttyUSB1,2 and 3 do not work at all. Therefore I restart ModemManager and Networkmanager, reconnect the modem and check in /var/log/message if it is connected to ttyUSB0. If not, I restart ModemManager and Networkmanager again. Very tedious procedure. I think there is a relation to the pin because if I use my Modem abroad with a SIM card without a PIN input everything works out of the box. So a fix would be great.
It looks like to be an Issue of the ModemManager, there are some similar issues with ZTE ttyUSB modems, lsusb Bus 001 Device 005: ID 19d2:0117 ZTE WCDMA Technologies MSM
I tried to fix it by downgrading the ModemManager to the version of F21, but i was not successful, i still get the same errorcode. After all i reinstalled the usb_modeswitch* that finally brought to another error of missing parameters. Then i installed F22 and the broadband USB stick worked without any problem. I believe that F23 messed up the ModemManager with udev and the Networkmanager. I would be happy to see a solution for that issue before the F22 runs out of uppdate service.
hmm, this does not look good Jan 11 20:57:21 chrissyboy.fritz.box ModemManager[1086]: <warn> Couldn't initialize PDP context with our APN: 'Sending command failed: 'Resource temporarily unavailable'' Jan 11 20:57:21 chrissyboy.fritz.box NetworkManager[1248]: <warn> (ttyUSB1): failed to connect modem: Sending command failed: 'Resource temporarily unavailable' I'm wondering if you could retest with the updated packages from here: https://bodhi.fedoraproject.org/updates/FEDORA-2016-494a721a73 Thank you, Lubo
The problem disappeared in the meantime for F23, so we can close that issue. Sorry i have overseen this topic.
