由于笔记本没有自带无线网卡，所以买了一块fast FW150US USB无线网卡。该网卡只自带了window下的驱动，经过一番折腾，终于安装好了Linux下的驱动，在此记录以便以后遇到同样问题能够快速解决。
首先查看网卡型号，如下：

在此看到芯片型号为RTL8188CUS，使用google可以找到该芯片驱动下载地址：
此时剩下的就是下载代码，编译，安装，重启系统即可。
之前担心找不到Linux下驱动，现在已经安装好驱动并发表该博文，又一次感受到Linxu的强大，一定要学好Linux！
今天（2012-12-15）新编译并安装了内核2.6.34.13，直接在原来编译基础上make install安装驱动，重启系统之后发现usb无线驱动不工作。原来驱动程序都是直接依赖内核代码的，内核换了，需要重新make才行。卸掉原来驱动，重新make，make install之后usb无线网卡工作正常。
