Ubuntu怎么安装新的主题？？

各位前辈，我用wubi安装好Ubuntu后，无线网卡无法驱动，由于没有别的联网方法，不可能联网更新。搜索了半天，也没有针对我这个机型的安装驱动方法（惠普CQ-40-514）。我现在该怎么办。。。

惠普官网瞧过了没。

瞧过了，米有啊。。。
人家官网只有Vista和win7的驱动，想找个xp的都难，更何况是linux的驱动了。。。

知道具体型号么。

你看这个：

里面“无线网卡”那一行写着“无线网卡 802.11b/g ”，这算啥型号。。。

贴上来看看

如下：
lspci

To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.
