互联网连接 10 秒后断开

我在 Ubuntu 20.04 中遇到了有线连接问题。当我重新启动有线连接时，互联网连接了 10 秒，然后互联网断开了。连接到另一个以太网后发生这种情况。我已经在同一个设备上的 Windows 中测试过，有线连接工作正常。

答案1

简短版本：安装r8168-dkms包：

apt install r8168-dkms

然后重新启动以停用旧驱动程序并激活新驱动程序。（这也可以不重新启动来完成，但重新启动更简单。）

长版本：这似乎是r8169驱动程序中的一个已知错误：

ubuntu 20.4-使用 r8169 重新传输

我运行了一些网络测试（iperf3），发现 ubuntu 20.4 内核 5.4.0-29 中存在大量重传。我使用模块 r8169 作为网络适配器

live iso 20.04 没有有线网络

我认为它可能也与这些上游错误报告有关：

通过 r8169 驱动程序提供服务的板载网络 Realtek RTL8111E 控制器无法在内核版本 5.3 (5.3.18-lp152.33-default openSUSE Leap 15.2) 和 5.8 (5.8.1-3.1.g846658e) 上提供稳定的网络连接。一些类似的错误报告中提到的解决方法是禁用 ASPM (pcie_aspm=off)，但这并不能稳定网络。

Starting from kernel 5.3-rc1, the r8169 driver oops during os boot.

如果您需要重新加载驱动程序而不重新启动，可以通过以下命令完成：

sudo rmmod r8169
sudo modprobe r8168
sudo /etc/init.d/networking restart

如果它在重新启动后停止工作，请尝试以下操作以确保r8169驱动程序不会在启动时加载：

echo 'blacklist r8169' | sudo tee -a /etc/modprobe.d/blacklist.conf
