Product: Networking Version: 2.5 Kernel Version: 4.1.12-1-default Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Other Assignee: shemminger@linux-foundation.org Reporter: cameronpoe@poczta.fm Regression: No When I start (boot) the system from shutdown state I can't connect to Internet because there is no network connection in pop-up network plasma menu (close to clock in right bottom of the screen) in new openSUSE Leap 42.1 with KDE 5. When I shutdown the laptop and start again (boot again) it still doesn't connect (no connection available), but if I restart (reboot) the system the connection works (shows in plasma networking pop-up menu). >>From what I can see in journalctl when I boot the laptop for the 1st time the system recognizes this modem as memory stick and there are errors in journalctl: NetworkManager[878]: (eth1): failed to find device 4 'eth1' with udev NetworkManager[878]: (eth1): new Ethernet device (carrier: OFF, driver: 'cdc_ether', ifindex: 4) kernel: cdc_ether 3-1:1.0 eth1: register 'cdc_ether' at usb-0000:00:12.2-1, CDC Ethernet Device, 58:2c:80:13:92:63 kernel: usbcore: registered new interface driver cdc_ether NetworkManager[878]: (eth1): device state change: unmanaged -> unavailable (reason 'managed') [10 20 2] kernel: cdc_ether 3-1:1.0 eth1: kevent 12 may have been dropped NetworkManager[878]: (eth1): link connected NetworkManager[878]: (eth1): device state change: unavailable -> disconnected (reason 'none') [20 30 0] ...but when I reboot the laptop the system recognizes it as modem strait away and there are no "failed" nor "dropped" messages. I will attach 2 files with journalctl from the 1st boot and the reboot. I have always been installing the Huawei E3131-s2 (Hi-Link) from Linux driver attached in the modem's internal memory and it always worked, but now when I reinstalled the openSUSE system to newer version 42.1 there was an "failed" error with runmbbservice so I deactivated it. Anyway, the connection did not work either. Another thing - when I unplug the modem and plug it back in it fails again and the connection vanishes (doesn't show up when I plug modem back) and I have to reboot the system to be able to connect to the Internet. I is annoying to always boot the system and reboot in order to connect t the Internet :( So, can anyone fix this please? -- You are receiving this mail because: You are the assignee for the bug.
