Ubuntu 16.04 Realtek RTL8111/8168/8411 以太网驱动程序未维持持久连接

我这周过得很糟糕，一直在尝试解决以太网连接问题。以太网正常工作了一分钟，然后就断开了连接。顶部的网络图标一直显示已连接，但我必须通过单击“有线连接 1”断开连接并重新连接，才能保持几秒钟/几分钟的连接。

为了解决这个问题，我每分钟运行一次 cron 作业来断开连接并重新连接，代码如下：

#!/bin/bash
sudo ifdown enp4s0
sudo ifup enp4s0

请帮忙。我需要一个更持久的解决方案来实现稳定的以太网连接。

) 将 IPv6 设置“方法”部分设置为“忽略”。3
) 将我的 Internet DNS 服务器更改为 8.8.8.8、8.8.4.4...等。4
) 将“MTU”更改为 9000。5
) 将接口文件更改为：auto lo iface lo inet loopback auto enp4s0 iface enp4s0 inet dhcp

看起来好像这个命令删除了 8.044 驱动程序，现在只剩下 8.043.02 驱动程序。

sudo apt-get -y dist-upgrade

答案1

来自评论...

  1. 你真的做需要在你的配置中运行 r8168-dkms

  2. 撤消你所做的所有更改...都没有解决问题，反而产生了新的问题

  3. 经过仔细检查，我发现您正在为 Ubuntu 17.10（在 16.04 系统上）使用 r8168-dkms (8.044.02-NAPI)。请安装正确的版本并重新测试。

  4. 在您的网络 GUI 中，您设置了多个“有线连接”配置文件。它们将被命名为有线连接、有线连接 1、有线连接 2 等。删除除有线连接之外的所有配置文件。

更新＃1：

假设当前状态dkms status显示r8168, 8.041.00 : added...

sudo dkms build r8168/8.041.00 -k "$(uname -r)/$(uname -p)"
sudo dkms install r8168/8.041.00 -k "$(uname -r)/$(uname -p)"

注意：您可能需要确认正确的值r8168/8.041.00（模块/版本）通过查看/usr/src或/var/lib/dkms/r8168。

dkms status

應該顯示r8168, 8.041.0 installed。

reboot
modinfo r8168 | grep -i version

应该说8.041.00。

更新 #2：

  • r8168 v8.041.00 对于 16.04.2（内核 4.8.0-58）来说太旧了
  • 我们现在使用的是 r8168 v8.043.02

更新 #3：

我们将彻底删除 r8168-dkms 并取消将 r8169 列入黑名单，然后从 Ubuntu 存储库重新安装 r8168-dkms。

  • sudo dkms remove r8168/8.043.02 -k "$(uname -r)/$(uname -p)"
  • sudo apt-get purge r8168-dkms
  • cd /var/lib/dkms
  • ls -al
    • 不应显示 r8168
  • cd /usr/src
  • ls -al
    • 不应显示 r8168.043.02
  • find /lib -name r8168.ko
    • 不应显示 r8168.ko
  • cd /etc/modprobe.d
  • ls -al r8168*
    • 不应显示任何文件
  • grep -i r816 *
    • 将 grep 的输出编辑为问题作为更新 #n
  • cd
  • sudo modprobe -r r8168
  • sudo update-initramfs -u -k "$(uname -r)"
  • 到此为止，通过 @heynnema 与我联系
