Created attachment 549423 [details] Syslog of ZTE MF-192 being attached, configured and trying to connect Description of problem: ZFE MF-192 USB HSPA modem is picked up but fails to connect using NetworkManager. The applet (KDE) shows a strong signal and network type (EDGE, where I am); but connecting fails. The modem is known to have a valid SIM card and credit, and connects succesfully from Windows XP. There is no PIN set. The light on the dongle flashes green to indicate it has access to the network (after initially flashing red at first whilst it finds the network, as it does on Windows). Interestingly, the dongle also has a mountable partition including Linux code, which appears to be for Fedora 11, and which disables NetworkManager (which I'm not willing to run, as I need it for other connections), and runs wvdial. Here is a copy of the tarball found in the "Linux" directory on the mountable partition: http://david.dw-perspective.org.uk/tmp/PCL_ORAKENICE.tar.gz I have attached the syslog of a complete session where I attach the dongle, and enter the configuration into the applet (KDE), and then try to connect. Version-Release number of selected component (if applicable): NetworkManager-0.9.2-1.fc16.x86_64 usb_modeswitch-data-20111023-1.fc16.noarch How reproducible: Every time Steps to Reproduce: 1. Insert dongle 2. Configure in NetworkManager applet using working settings from Windows XP (APN bew.orange.co.ke username=password=orange, dial *99#). 3. Click on the "Orange (EDGE)" icon in NetworkManager applet Actual results: Does not connect. Expected results: Successful network connection. Additional info: Syslog attached
I just tried out this modem with kppp (KDE's PPP dialer). Works beautifully! 1) /bin/systemctl stop NetworkManager.service 2) /usr/sbin/kppp 3) Enter the details (*99#, /dev/ttyACM0), didn't need to change any defaults 4) PROFIT!!! I'm using it now as I add this note.

OK - I can see the problem now. NetworkManager is trying to dial out on /dev/ttyACM1 But, as the success with kppp shows, it's /dev/ttyACM0 that works. (The device is supplying ttyACM0, 1 and 2 device nodes). Is this some rule in ModemManager that needs modifying? I'm not very familiar with this stuff. I'll stop here, as I've got what I want (a working modem in Fedora) - I guess you guys will know where to apply the fix.
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.
