下載完解壓到內核下的drivers/net/wireless目錄，
在此目錄下的Kconfig文件添加如下
source "drivers/net/wireless/rtl8192cu/Kconfig"
在此目錄下的Makefile文件添加如下
obj-$(CONFIG_RTL8192CU) += rtl8192cu/
然後make menuconfig

保存配置編譯內核
但是編譯出錯了，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
其實此時是缺少了配置CONFIG_WIRELESS_EXT=y
但是CONFIG_WIRELESS_EXT又依賴如下的配置
CONFIG_IPW2200=y
所以配置完
CONFIG_IPW2200=y
就基本完成了。
然後再編譯，通過了。
當你linux啓動完成之後，你會發現一個wlan0設備，這裏就不做具體介紹了，如果你想通過無線連接到arm板，就設置網卡爲ad-hoc模式
打個比方
ifconfig wlan0 18.18.18.18 //設置wlan0的ip地址
iwconfig wlan0 essid luhao //設置名稱luhao
iwconfig wlan0 mode ad-hoc //設置工作模式 ad-hoc
這個時候你應該就能搜索到luhao這個wifi熱點了。
