我使用ndiswrapper的方式驱动这块网卡。
首先需要安装ndiswrapper，在debian sid中， ndiswrapper包括3个软件包ndiswrapper-common，
ndiswrapper-source，ndiswrapper-utils-1.9，其中ndiswrapper-source是ndiswrapper内核模块的源代码，可以使用module-assistant安装。
module-assistant会根据当前内核的情况生成并安装kernel module软件包， 同时将根据包依赖关系安装ndiswrapper-common，ndiswrapper-utils-1.9两个软件包。 在我的系统中，安装了如下软件包：
| blueice2:~# dpkg -l |grep ndis ii ndiswrapper-common 1.47-2 Common scripts required to use the utilities ii ndiswrapper-modules-2.6.22-2-k7 1.47-2+2.6.22-4 ndiswrapper Linux kernel module ii ndiswrapper-source 1.47-2 Source for the ndiswrapper Linux kernel modu ii ndiswrapper-utils-1.9 1.47-2 Userspace utilities for the ndiswrapper Linu |
由于kernel中除ndiswrapper外还有一个模块bcm43xx可用来驱动bcm4300系列无线网卡，需要在/etc/modprobe.d/blacklist中增加一行“blacklist bcm43xx”来阻止bcm43xx在启动时被载入，并在/etc/modules中增加行"ndiswrapper"设置系统启动时载入ndiswrapper。重启系统使设置生效。
从下载bcm43xx在windows下的驱动，在windows下运行或使用wine运行，生成解压后的目录SP34152A， 这个目录下有个文件bcmwl5.inf。
运行ndiswrapper -i /
| blueice2:~# ndiswrapper -l bcmwl5 : driver installed device (14E4:4311) present (alternate driver: bcm43xx) |
此时可使用ifconfig -a查到wlan0网络接口，并可使用iwconfig配置该接口.

在我的环境中只许需要配置好密钥和密钥序号，驱动程序就能够找到essid，无须收工设置。
在设置密钥时要特别注意安全模式， ndiswrapper默认的安全模式是“restricted”，而我的环境中无线路由器的模式安全模式为“open”，为这个问题折腾了一天的时间。
使用ndiswrapper也可以用于别的无线网卡，我还测试了一块tp-link TL-WN321G的usb 无线网卡， 工作正常。
后记：
在使用的过程中发现一个小bug：如果在windows中按“蓝色的无线网络按钮”将无线网卡移出后， 进入Linux， 无论怎么按“蓝色的无线网络按钮”都无法启用无线网络。不过删除/etc/modprobe.d/blacklist中的“blacklist bcm43xx”行， 并运行update-initramfs -u更新initrd,img文件后“蓝色的无线网络按钮”就可以启动无线网络了。
