win7+ubuntu双系统，Ubuntu上不去网

[lxl_0044]

各位好，我的Ubuntu上不去网了，win7正常没问题。

win7上，各参数请看下：

==============================================

然后我安装完Ubuntu后，发现一直上不去网，查看ifconfig连ip都没有，

于是手动进行了配置：
1、ipv4栏：（手动）
ip：172.16.22.69
netmask：255.255.255.0
gateway：172.16.22.1
dns：172.16.3.12
2、ipv6（自动）

然后发现右上角变成了熟悉的上下箭头形状。

但之后查看还是上不去网，这是以下的系统信息：

我感觉像是ipv6有问题？ 好像ipv6的地址不是win7中的那个，
我在网上查了一些资料也没找到什么有用的信息，麻烦哪位朋友帮我看下吧，感激不尽。

是否是因为我某些地方配置不对导致呢？

哪位大哥了解，麻烦跟我说下 要怎么配置吧
折腾了1天，还是上不去网。。
