1. 检查内核版本 和硬件
#uname -a

2 . 编译源码
注意：yum install broadcom-wl 不能用，Fedora 14 可以的
到官方下载驱动包，但是那个包编译不了，（这里可以下载 我改过的代码 )
KBUILD_NOPEDANTIC=1 make -C /lib/modules/`uname -r`/build M=`pwd`
make[1]: Entering directory `/usr/src/kernels/2.6.38.2-9.fc15.x86_64'
CC [M] /root/broadcom_bcm4313/src/wl/sys/wl_linux.o
/root/broadcom_bcm4313/src/wl/sys/wl_linux.c: In function ‘wl_attach’:
/root/broadcom_bcm4313/src/wl/sys/wl_linux.c:485:3: error: implicit declaration of function ‘init_MUTEX’ [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
make[2]: *** [/root/broadcom_bcm4313/src/wl/sys/wl_linux.o] Error 1
make[1]: *** [_module_/root/broadcom_bcm4313] Error 2
make[1]: Leaving directory `/usr/src/kernels/2.6.38.2-9.fc15.x86_64'
需要在wl_linux.h 186 行加上
#define init_MUTEX(LOCKNAME) sema_init(LOCKNAME,1);
3. 编译好的 wl.ko 复制到
/lib/module/xxxxx/extra/wl/wl.ko
[root@Neil-PC wl]# pwd
/lib/modules/2.6.38.2-9.fc15.x86_64/extra/wl
[root@Neil-PC wl]# ll
total 3964
-rw-r--r-- 1 root root 4058778 Apr 15 08:32 wl.ko
4. 插入模块
检测并自动插入，成功的话直接返回，无错误
#modprobe wl
5. reboot 就可以使用了
当我们进行第四步时可能会遇到 模块加载失败，找不到模块的错误提示。
那么需要以下几步，就可以解决这个问题了。
1，cp wl.ko /lib/modules/2.6.XXXXXX/kernel/ 目录下
2，执行 depmod 命令。
3，modprobe wl。
4，reboot
OK。 这样就确保安装成功了。
