http://bugzilla.opensuse.org/show_bug.cgi?id=960467 Bug ID: 960467 Summary: NetworkManager fails to connect with Huawei Mobile Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.1 Hardware: x86-64 OS: openSUSE 42.1 Status: NEW Severity: Normal Priority: P5 - None Component: Network Assignee: bnc-team-screening@forge.provo.novell.com Reporter: stschoettl@web.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- After plugging in a USB Huawei Mobile GSM modem (idVendor=12d1, idProduct=1003, sold - among others - as "Fonic Surfstick" in Germany), it is not possible to connect via broadband with this device. However, after restarting NetworkManager, the connectin works fine. The bahaviour is similar to https://bugzilla.redhat.com/show_bug.cgi?id=1230681 . How to reproduce: 1. Make sure NetworkManager and ModemManager are enabled and running 2. Create a NetworkManager connection for the Huawei Mobile 3. Reboot 4. Log in to a graphical desktip session (in my case: lxde) 5. Make sure the NetworkManager applet is running and working 6. Plug in the USB Huawei Mobile GSM modem 7. Unlock the SIM card if necessary 8. Try to connect with the Huawei Mobile Error messages from journalctl: Dez 30 22:10:02 probook NetworkManager[27645]: <info> (ttyUSB1): Activation: starting connection 'FONIC Surfstick' (d16f9a53-30ee-4f1c-8af1-2609ab4f2d15) Dez 30 22:10:02 probook NetworkManager[27645]: <info> (ttyUSB1): device state change: disconnected -> prepare (reason 'none') [30 40 0] Dez 30 22:10:02 probook NetworkManager[27645]: <warn> (ttyUSB1): Failed to connect 'FONIC Surfstick': Connection requested both IPv4 and IPv6 but dual-stack addressing is unsupported by the modem. Dez 30 22:10:02 probook NetworkManager[27645]: <info> (ttyUSB1): device state change: prepare -> failed (reason 'modem-init-failed') [40 120 28] After restarting the NetworkManager service, the connection can be made successfully. The error message about "IPv4 and IPv6" is misleading. I tried setting the connection to IPv4 only and it did not work either (though the message changed to "Connection requested IPv4 but IPv4 is unsuported by the modem.") -- You are receiving this mail because: You are on the CC list for the bug.
