Ubuntu16.04戴尔G7的以太网连接问题

Question

我有问题，连接到以太网连接上的ubuntu16.05在戴尔G7笔记本电脑。计算机连接到wifi，但不显示以太网连接。我用几根电缆进行了测试，但问题仍然存在。这台电脑是新的，我不知道如何解决这个问题。当连接网络选项卡上的以太网按钮时，wifi信号就会闪烁，并且两个箭头以太网符号永远不会出现。我是新来的网络设置，所以任何帮助都将不胜感激。谢谢。

以下是ifconfig的输出：

我的/etc/网络/接口文件如下所示：

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

#primary ethernet interface
auto enp60s0 
iface enp60s0  inet dhcp

Answer 1

你有一个IPv6地址。因此，我想您可以通过关闭Ipv6并重新启动接口来获得连接。

1.关闭IPv6

请添加

net.ipv6.conf.all.disable_ipv6 = 1

net.ipv6.conf.default.disable_ipv6 = 1

net.ipv6.conf.lo.disable_ipv6 = 1

至

/etc/sysctl.conf

然后在命令行上键入以下命令并按Enter键

sudo sysctl -p

这应该足以关闭IPv6，但是有一些bug，因此在启动Ubuntu时，我们需要编写一些脚本来自动关闭IPv6。

请创建一个新文件/etc/rc.local并添加以下内容

#!/bin/bash
# /etc/rc.local

# Load kernel variables from /etc/sysctl.d
/etc/init.d/procps restart

exit 0

并授予执行文件的权限。

chmod 755 /etc/rc.local

2.重新启动接口

ifdown enp60s0 && ifup enp60s0
