我最近将 Ubuntu 从 12.04 升级到了 14.04，结果我的 4G LTE 连接丢失了。（在 Windows 中它工作正常。我有双重启动）。当我尝试通过 UNE 图标连接时，Ubuntu 回复道：
设备已断开连接或不可用
输出lsusb表明4G移动调制解调器（HUAWEI E398）已被识别，如下所示：

我卸载了驱动程序（由供应商提供）并尝试再次安装，但 Ubuntu 14.04 回复了一些错误消息，输出来自

Now please enter any key to finish other installations.
我不明白发生了什么，我在 Ubuntu 12.04 中编译和连接 4G 移动模型没有问题，我希望我能回到 12.04！有没有人遇到过类似的问题并解决了？这个问题让我抓狂，任何帮助都将不胜感激。
答案1
请不要使用 Une、Tigo 和其他 Movile 宽带设备供应商的供应商驱动程序。这些驱动程序会导致很多问题，并且很容易破坏您的互联网连接。我遇到了与 Movistar 的 ZTE 调制解调器类似的问题，我尝试安装驱动程序，但这让我无法上网，并破坏了我的调制解调器管理器。检查您是否安装了 GCC、g++ 和 cmake。您可以安装调制解调器管理器 GUI，它是为 Ubuntu 设计的。
答案2
您可以通过在终端中运行将调制解调器切换到仅调制解调器模式
echo -e 'AT^SETPORT="A1,A2;10,12,13,A2"\r' | sudo tee /dev/ttyUSB0
然后重新插入调制解调器并等待 30 秒。
经过此设置后，调制解调器可能无法与 Windows 中的供应商软件配合使用。您可能需要在那里设置电话连接。
可以通过以下方式撤消此设置
echo -e 'AT^SETPORT="A1,A2;12,16,A1,A2"\r' | sudo tee /dev/ttyUSB0
