网卡是Realtek rtl8111b/8168b。
网络是长城宽带的有线、拨号上网，只知道用户名和密码。
安装过程中我就想联网，但失败。安装完后我继续联网仍然失败。有人说要把DSL的服务填上、我填上了Internet仍然拨号失败（是不是只填上用户名,服务,密码就行了？）。
只有VISTA能上网，Xubuntu上不了网。
于是我这两天进入VISTA系统查找资料，有人说ifconfig中如果没有出现eth0就是驱动没有，我看了系统默认使用的网卡驱动是r8169，我在VISTA里查看的是r8168（VISTA里安装的也是8168）。
搜了好多帖子，终于下狠心安装r8168驱动。
我是参照如下安装的：
https://ubuntuforums.org/showthread.php ... l8111+8168
安装完毕后，DSL仍然不能上网。我查看了lspci -v，发现模块是r8168，但使用的驱动却是r8168。我lsmod | grep r816了，发现输出了r8168、r8169两个驱动。
我还以为是驱动问题，又开始狂搜贴，终于只剩下一个r8168驱动了。
但是仍然不能上网，新手到这里已经蒙了，向各位高手求助，先提前谢谢大家！！
从始至终我ifconfig输出的没有eth0，一直是ens33，我也不明白什么意思，不知道为什么连不上网？
我把xubuntu上终端输入的代码发上来（在xubuntu保存的txt文件，结果在win里格式都变了，草草调整了一下）：
请高手帮忙看看，帮我找找不能上网的原因，谢谢大家！
