我在带有 Windows 7 的 Dell Inspiron 双启动系统上安装了新的 Mint Cinnamon 21.1，并且我的 USB 调制解调器华为 E173u-2 有问题。在 Mint 安装调制解调器工作正常后，它被检测到，我能够在网络管理器中创建连接并连接到互联网。没问题。我将其放置了几个小时，最终连接断开。所以我尝试再次连接，但我无法再连接了。发生了一些事情，现在网络管理器小程序不会显示我的互联网提供商名称及其信号强度，并且我无法通过调制解调器建立连接。我陷入了“连接失败。网络连接激活失败。”； “断开连接”。同一调制解调器可与 Pendrive 的 Mint Cinnamon 21.1 live USB 配合使用。在过去的两年里，它与 Mint 19.3 配合得很好。在它崩溃之前我做的唯一一件事就是更改我的用户密码。
我重新安装了网络管理器，尝试了另一个内核，仍然没有连接。更改端口 - 没什么。电源管理已关闭。
现在三天过去了，我已是束手无策了。它立刻起作用了，但现在不起作用了。我无法使用互联网，调制解调器无法连接，移动宽带没有显示在网络设置中，但我在网络连接中创建连接没有问题，但无法建立连接。信号正常，USB 端口正常，调制解调器正常。网络管理器可与我的智能手机上的 WiFi 和 USB 网络共享配合使用，没有任何问题。网络管理器、调制解调器管理器和 USB 模式开关均已更新。
除了重新安装 Mint 之外，我还能做什么来让它再次工作？为什么我的调制解调器不再工作以及如何修复它？我怎样才能找到这个问题的原因是什么？

我是 Linux 新手，所以你想让我做的任何事情来帮助我解决这个问题都需要清晰且一步一步地沟通，就像你与一个完全的新手交谈一样。提前致谢。
答案1
该问题是由调制解调器管理器版本 1.20.0-1~ubuntu22.04.1 引起的。使用版本 1.18.6-1 调制解调器效果很好。我在重新安装我的薄荷并仔细查看更新管理器中的更新后发现了这一点。
