为了解决笔记本没有自带无线网卡的问题，我购买了一块fast FW150US USB无线网卡。然而，该网卡只提供了Windows下的驱动程序。经过一番努力，我终于成功安装了Linux下的驱动程序。在这篇文章中，我将记录下来，以便将来遇到类似问题时能够快速解决。

首先，我查看了网卡的型号，如下所示：

根据这些详细信息，我发现芯片型号是RTL8188CUS。通过使用Google，我找到了该芯片的驱动程序下载地址。接下来，我下载了代码，进行了编译和安装，并重新启动了系统。这样，我成功安装了驱动程序。

之前，我担心在Linux下找不到适用的驱动程序，但现在我已经成功安装并发布了这篇博文。这次经历再次让我感受到了Linux的强大，所以我一定要好好学习Linux！

今天（2012-12-15），我编译并安装了内核2.6.34.13。在原有的编译基础上，我直接使用make install命令安装了驱动程序。然而，重启系统后，我发现USB无线网卡无法正常工作。原来，驱动程序直接依赖于内核代码，所以当内核更换后，需要重新进行编译。因此，我卸载了原来的驱动程序，重新进行了编译和安装，之后USB无线网卡才能正常工作。
