下载完解压到内核下的drivers/net/wireless目录，

在此目录下的Kconfig文件添加如下

source "drivers/net/wireless/rtl8192cu/Kconfig"

在此目录下的Makefile文件添加如下

obj-$(CONFIG_RTL8192CU) += rtl8192cu/

然后make menuconfig

保存配置编译内核

但是编译出错了，如下

CC drivers/net/wireless/rtl8192cu/hal/rtl8192c/usb/rtl8192cu_led.o

CC drivers/net/wireless/rtl8192cu/hal/rtl8192c/usb/rtl8192cu_xmit.o

CC drivers/net/wireless/rtl8192cu/hal/rtl8192c/usb/rtl8192cu_recv.o

CC drivers/net/wireless/rtl8192cu/hal/rtl8192c/rtl8192c_sreset.o

CC drivers/net/wireless/rtl8192cu/os_dep/osdep_service.o

CC drivers/net/wireless/rtl8192cu/os_dep/linux/os_intfs.o

drivers/net/wireless/rtl8192cu/os_dep/linux/os_intfs.c: In function 'rtw_init_netdev':

drivers/net/wireless/rtl8192cu/os_dep/linux/os_intfs.c:779: error: 'struct net_device' has no member named 'wireless_handlers'

make[4]: *** [drivers/net/wireless/rtl8192cu/os_dep/linux/os_intfs.o] Error 1

make[3]: *** [drivers/net/wireless/rtl8192cu] Error 2

make[2]: *** [drivers/net/wireless] Error 2

make[1]: *** [drivers/net] Error 2

make: *** [drivers] Error 2

其实此时是缺少了配置CONFIG_WIRELESS_EXT=y

但是CONFIG_WIRELESS_EXT又依赖如下的配置

CONFIG_IPW2200=y

所以配置完

CONFIG_IPW2200=y

就基本完成了。

然后再编译，通过了。

当你linux启动完成之后，你会发现一个wlan0设备，这里就不做具体介绍了，如果你想通过无线连接到arm板，就设置网卡为ad-hoc模式

打个比方

ifconfig wlan0 18.18.18.18 //设置wlan0的ip地址

iwconfig wlan0 essid luhao //设置名称luhao

iwconfig wlan0 mode ad-hoc //设置工作模式 ad-hoc

这个时候你应该就能搜索到luhao这个wifi热点了。
