正如我在标题中所说，我无法在 Ubuntu 16.04 上连接到路由器，但我可以通过双启动的 Windows 10（同时使用以太网和 wifi）连接。我还可以从手机和笔记本电脑等其他设备连接，因此我认为路由器不是问题所在。
当我进入“系统偏好设置 -> 网络 -> 有线”时，系统提示我的电缆已拔出，但实际上并没有，以太网在 Windows 上是可以使用的。今天之前我可以连接到这个路由器，但由于某些未知原因，现在无法再连接。我通常通过以太网连接，但我也尝试过 wifi，但似乎也不起作用。Ubuntu 根本检测不到路由器。但是，我可以连接到其他网络（我目前正在从另一个网络发布此信息），所以我不确定问题是什么。
我尝试了网上的一些解决方案，但这些解决方案都没有用。我当然尝试过重启，也尝试过禁用“启用 Wi-fi”，但都无济于事。我对 Linux 和网络不太了解，所以我提前道歉。

我也尝试在 Ubuntu 论坛上询问这个问题，但没有得到太多回复，所以我在这里提问。提前谢谢大家。
答案1
我能够从中找到解决方案关联。我所要做的就是下载驱动程序。问题是我的电脑运行的是 r8169 驱动程序，而我本应该使用 r8168。
