华为EC156移动宽带无法与Ubuntu 14.04 LTS 64位上的网络管理器配合使用
使华为移动宽带E173在Ubuntu 13.10中工作 。 我和huawei ec156调制解调器有相同的情况。使用wvdial它与/ dev / ttyUSB0完美配合，但由于某种原因它与网络管理器使用/ dev / ttyUSB2并且无法连接（即使它被NW管理器检测到）。 可能是代码/配置实现的方式。 我真的想使用网络管理器更容易连接，并使用网络共享将数据卡用作Wifi热点。

该器件支持额外的SIM，因此ttyUSB2和ttyUSB0是CDMA
我在ubuntu 13.10中尝试过配置USB调制解调器（华为EC156）的解决方案。
问题是“我可以手动配置网络管理器以使用ttyUSB0而不是ttyUSB2”
可能是一个解决方法是提供一些选项来指定正确的调制解调器和AT命令就像一个普通的拨号器。
它已被计算机识别为无线数据调制解调器模式。 因此需要将该模式切换到移动宽带模式。 该模式切换由usb-modeswith包完成。 确认天气usb-modeswitch已安装：
dpkg --get-selections | grep -v deinstall
这将列出已安装的软件包。 查看天气usb-modeswitch是他们的。（通过alphebatical订单）
如果存在，请尝试安装华为宽带调制解调器需要正常运行的所有软件包。
sudo apt-get install python-pysqlite2 python-pysqlite2-doc python-pysqlite2-dbg hal python-messaging wader-core
然后还安装network-manager需要正常工作的所有软件包。 （它的依赖）
