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

我有一个糟糕的一周试图解决我的以太网连接问题。 在失去连接之前，以太网工作正常1分钟。 顶部的网络图标始终显示为已连接，但我必须通过单击“有线连接1”断开连接并重新连接几秒钟/几分钟的连接。

要解决此问题，我每分钟都有一个cron作业断开连接并重新连接以下代码行：

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

请帮忙。 我需要一个更稳定的以太网连接的永久解决方案。

我做过的事情：

1）使用Synaptic安装r8168-dkms。
2）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

以及静态。
6）sudo apt-get purge r8168-dkms来自Ubuntu 14.04有线连接保持断开连接
7） https://unixblogger.com/2011/10/18/the-pain-of-an-realtek-rtl8111rtl8168-ethernet-card/上的所有内容
8）安装旧版本的r8168，然后：

 sudo update-initramfs -u echo "blacklist r8169" | sudo tee -a /etc/modprobe.d/blacklist.conf 

9）阅读https：// ubuntuforums dot org / archive / index.php / t-2291730.html页面
10）https：// ubuntuforums上的所有内容dot org / showthread.php？t = 2248047
11）冷启动。
12）

 sudo sh -c "echo 'net.ipv6.conf.all.disable_ipv6 = 1' >> /etc/sysctl.conf" sudo sh -c "echo 'net.ipv6.conf.default.disable_ipv6 = 1' >> /etc/sysctl.conf" sudo sh -c "echo 'net.ipv6.conf.lo.disable_ipv6 = 1' >> /etc/sysctl.conf" sudo sysctl -p sudo sed -i 's/false/true/g' /etc/NetworkManager/NetworkManager.conf sudo reboot -i NOW

在尝试使用r8168 V 8.042后失败了……我尝试了8.043.02版并取得了一些成功，尽管我们还没有达到最终解决方案。

更新5

似乎这个命令删除了8.044驱动程序，现在剩下的就是8.043.02驱动程序了。

 sudo apt-get -y dist-upgrade 

Answer 1

从评论…

1. 你真的需要在你的配置中运行r8168-dkms

2. 撤消您所做的所有更改…他们没有解决问题，只创建了新的问题

3. 仔细阅读后，我发现您使用的是r8168-dkms（8.044.02-NAPI）用于Ubuntu 17.10（在16.04系统上）。 请安装正确的版本并重新测试 。

4. 在网络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连接。

更新＃1：

假设当前状态是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：您可能需要通过查看/usr/src或/var/lib/dkms/r8168来确认r8168 / 8.041.00 （模块/版本）的正确值。

 dkms status 

应该显示r8168, 8.041.0 installed 。

 reboot modinfo r8168 | grep -i version 

应该说8.041.00 。

更新＃2：

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

更新＃3：

我们将完全删除r8168-dkms和un-blacklist r8169，然后从Ubuntu repos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
  • 不应该显示r8168
• cd /usr/src
• ls -al
  • 不应该显示r8168.043.02
• find /lib -name r8168.ko
  • 不应该显示r8168.ko
• cd /etc/modprobe.d
• ls -al r8168*
  • 应该显示没有文件
• grep -i r816 *
  • 将grep的输出编辑为更新#n
• cd
• sudo modprobe -r r8168
• sudo update-initramfs -u -k "$(uname -r)"
• 停在这里，在@heynnema打我
