相关让华为移动宽带 E173 在 Ubuntu 13.10 上运行。我的华为 ec156 调制解调器也遇到了同样的情况。使用 wvdial 时，它可以与 /dev/ttyUSB0 完美配合，但使用网络管理器时，由于某种原因，它使用 /dev/ttyUSB2 并无法连接（即使 NW 管理器检测到它）。可能是代码/配置实现方式的问题。我真的很想使用网络管理器，以便更轻松地实现连接，并使用网络共享将数据卡用作 Wifi 热点。

该设备支持附加 SIM，因此 ttyUSB2 和 ttyUSB0 为 CDMA
我已经尝试过这里的解决方案在 ubuntu 13.10 中配置 USB 调制解调器（华为 EC156）还 。
问题是“我可以手动配置网络管理器以使用 ttyUSB0 而不是 ttyUSB2 吗？”
也许一种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，就像普通拨号器一样。
答案1
计算机已将其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。该模式切换由包完成usb-modeswith。确认 usb-modeswitch 是否已安装：
dpkg --get-selections | grep -v deinstall
这将列出已安装的软件包。查看是否usb-modeswitch有其他软件包。（按字母顺序排列）
如果存在，则尝试安装华为宽带调制解调器正常运行所需的所有软件包。
sudo apt-get install python-pysqlite2 python-pysqlite2-doc python-pysqlite2-dbg hal python-messaging wader-core
network-manager然后还安装所有需要正常工作的软件包。（其依赖项）
