网络无人认领，互联网不起作用？

我刚刚在我的笔记本电脑戴尔Vostro上安装了Linux Mint，但网络无法正常工作 - 当我运行lshw时，我收到了“-network UNCLAIMED”消息。

uname -a

linux vostro 3.5.0-17通用x86_64

键入lshw显示以下内容：

       *-network UNCLAIMED

            configuration: latency=0
            resources: memory:f1800000-f183ffff ioport:2000(size=128)

我怎样才能使网络正常工作？
