Wifi 通常运行良好，但有时会变得非常慢或完全断开连接。这种情况随机发生，我在 Windows 10 中没有遇到此类问题。我想知道 r8169 驱动程序是否有问题？我读到过它可能很麻烦。重新启动、启动 Windows、再次重新启动，然后启动 Ubuntu 后，问题似乎自行解决。不过，我希望有一个更永久的修复方法。
我尝试用 r8168 替换 r8169，但无法使用 r8168，因为它说无法验证模块并且缺少所需的密钥。

答案1
您所提到的驱动程序与无线问题无关。
如果你遇到了以太网问题，你应该用r8168-dkms存储库中的驱动程序替换有问题的 r8169 驱动程序，和secure boot在 BIOS 中关闭。
