Please reproduce the problem and then attach the complete file /var/log/syslog from the system. The previous JournalErrors doesn't appear to include the important data from usb-modeswitch or NetworkManager/ModemManager.
Also, lxcbr0 is not related in any way to the modem; its IP address is set up automatically, and all of it comes from lxc, a container management tool that is apparently installed on your system. ** Changed in: usb-modeswitch (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to usb-modeswitch in Ubuntu. https://bugs.launchpad.net/bugs/1483257 Title: Huawei E3372 (& other hilink dongles?) cannot be used for connecting to the internet Status in usb-modeswitch package in Ubuntu: Incomplete Bug description: I have Huawei E3372 which works directly when I plug it in Windows 10, but on Ubuntu I cannot use it for connecting to the internet. It's light is cyan which means it's connected to 4G network, but it does nothing. It appears in lsusb: `Bus 001 Device 003: ID 12d1:1f01 Huawei Technologies Co., Ltd. E353/E3131 (Mass storage mode)` And it also appears in ifconfig: ``` lxcbr0 Link encap:Ethernet HWaddr FILTERED inet addr:10.0.3.1 Bcast:0.0.0.0 Mask:255.255.255.0 inet6 addr: fe80::FILTERED/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:58 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:8993 (8.9 KB) ``` I also don't understand where the address 10.0.3.1 comes from as in Windows the control panel was in 192.168.8.1 or something like it. I also found another bug report, https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1424181 but I don't think this is a dupicate as from the title it looks like it doesn't appear in lsusb and that bug has expired. This package also seems to have bug reports for other dongles.
