Ubuntu 12.04 LTS 64 位无互联网连接

今天我决定在我当前的 Windows 7 机器上通过 USB 尝试 Ubuntu 12.04 LTS。我从 USB 运行 Ubuntu 并选择试用版。我无法连接到互联网，我使用以太网端口插入。由于我是 Linux 新手，我不确定如何或需要提供什么信息才能获得帮助。如果这个问题已经得到解答，我提前道歉，但我无法找到我的问题的答案。

提前致谢-

这些数据有用吗？我更改了 IP...

$ sudo lshw -C nekwork

假设您的路由器是 172.16.12.1，那么您的问题是您的机器不知道将 Internet 绑定的数据包发送到那里。

路由添加默认网关 172.16.12.1

这样就会通过该地址发送 LAN 上不包含的所有内容。

如果那不是您的路由器，请找出您的路由器的地址并将其代入。
