Description of problem: Initiation of a "Mobile Broadband" connection is flaky -- the user has to click "Mobile Broadband" -> "Connect" more than once, for the connection to succeed, even if the signal is strong enough. Version-Release number of selected component (if applicable): Name : NetworkManager Version : 0.9.9.0 Release : 15.git20131003.fc20 Name : ModemManager Version : 1.1.0 Release : 2.git20130913.fc20 How reproducible: Connection initiation fails _very_ frivolously, but is stable, once established. Steps to Reproduce: 1. Buy an Ericsson H5321 gw 3G modem -- not sure about how others fare 2. Try to initiate a 3G connection -- imperfect conditions might amplify the issue, I guess Actual results: "Mobile Broadband" takes several "Connect" clicks to succeed. Expected results: "Mobile Broadband" should take a single "Connect" click to succeed.

Created attachment 833556 [details] Output from "journalctl --since today" after the experiment.
I'm having similar experiences with the same hardware. I'm trying to give you some more information to debug the issue. I provide the output of "mmcli". I also provide the output of "journalctl --since today" after having done the following steps: 1 Boot 2 Connect from panel. It says the broadband is "inactive" before I click. This fails. 3 Connect from the panel again. This time it says the broadband is "off" before I connect. This time it succeeds. 4 Disconnect from panel. 5 Connect again from panel. This fails immediately. 6 Repeat 5, same result. 7 Open "network settings" dialog, and turn off the broadband in there. 8 Turn on in n-s. Now it believes it is connected; the panel indicates that for example. But I can't get anywhere over the net. 9 Turn off in n-s. 10 Turn on in n-s. Fails 11 Connect from panel. Fails 12 Turn off and on in n-s. 13 Connect from panel, fails. 14 Turn off the computer. 15 Turn on the computer. 16 Connect from panel. Fails as in 2. 17 Connect from panel. Succeeds as in 3. End of experiment. Previous days when I have tried to get this to work I've seen in the output of journalctl that NetworkManager has tried to use dhclient to get an IP address. That too always fails. In today's experiment, that didn't occur.

This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
