需要帮助更改以太网驱动程序

我的以太网驱动程序有问题，似乎加载了错误的驱动程序。它是 realtek 8125，但加载的驱动程序适用于 r8169。我最近确实从他们的网站安装了驱动程序，但内核也更新到了 5.9- 版。有趣的是，以太网可以工作，但峰值为 12mpbs（而不是 75mpbs）。

在不破坏系统的情况下安装正确驱动程序的最佳方法是什么？这是我在 2020 年第五次安装 Ubuntu，但我已经开始掌握它了。

我找到了解决方案。更新内核后，我不得不重新安装 Realtek 驱动程序。因此，当我将内核从 5.8 更新到 5.9 时，似乎不得不再次重新安装驱动程序。不确定是什么原因造成的，但它解决了问题。谢谢您的帮助！
