Me too. If the connection is broken (whether by me using NetworkManager, or by the modem "hanging up" contrary to my wishes), then attempting to reconnect with NetworkManager fails. NetworkManager does not show any signs. Additional information: If I kill modem-manager before attempting to reconnect, the reconnection succeeds. Modem: Pantech UML-290 modem from Verizon Packages: ModemManager-0.4-4.git20100720.fc13.i686 NetworkManager-0.8.1-10.git20100831.fc13.i686 ppp-2.4.5-9.fc13.i686 I will attach a stretch of /var/log/messages spanning the following sequence, punctuated approximately by log lines with the "uml290-adventure" tag: 1. I insert the modem. 2. Works great. 3. I disconnect using NetworkManager. 4. I try, and fail, to reconnect using cnetworkmanager. 5. I kill modem-manager. 6. I successfully connect using cnetworkmanager. Created attachment 475321 [details]
var/log/messages contrasting failed and successful reconnections
Maybe the patch proposed in https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/566812/comments/8 can help... First, the UML290 is an odd beast that isn't quite yet supported because it really requires a proprietary protocol go make use of the device (to actually get LTE speeds since PPP is a bottleneck, and to roam between LTE and EVDO networks). But second, it appears that ModemManager is not talking correctly to the device. Can you get a bit more debug output from modem-manager? Try the following: 1) unplug your device 2) get a root terminal 3) mv /usr/sbin/modem-manager / 4) killall -TERM modem-manager 5) /modem-manager --debug 6) replug your dongle, reproduce the issue 7) paste or attach that log output from modem-manager into this bug report 8) hit Ctl+C to stop modem-manager 9) mv /modem-manager /usr/sbin/modem-manager and then we can diagnose what's going on. (I no longer have the use of a UML-290. Retiring from the cc list.) still buggy in: NetworkManager-0.9.2-1.fc16.x86_64 NM no longer displays the Mobile Broadband connection possibility for me, I will reply after a reboot in the future. Huawei E220. Remote login upon request. This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 WONTFIX if it remains open with a Fedora 'version' of '16'. 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 prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 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 to click on "Clone This Bug" and open it against that version of Fedora. 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. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 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. Thank you for reporting this bug and we are sorry it could not be fixed. |
