linux wifi 8192移植及部分wifi工具的使用

8192 在imx53 linux上移植
8192wifi驱动

1.编译8192.ko

编译过程是进入8192，执行
./make_drv
选1
添加一个新的CONFIG_PLATFORM_ARM_MX53=y，把其他的那个改成n
编辑Makefile
添加下面代码
ifeq ($(CONFIG_PLATFORM_ARM_MX53), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN -DCONFIG_WISTRON_PLATFORM
ARCH := arm
CROSS_COMPILE := /opt/freescale/usr/local/gcc-4.4.4-glibc-2.11.1-multilib-1.0/arm-fsl-linux-gnueabi/bin/arm-none-linux-gnueabi-
KVER := 2.6.35
KSRC ?= /home/vmuser/ltib_x7/ltib/rpm/BUILD/X7_kernel
endif
执行
make
会产生8192cu.ko
搞到板子上
insmod 8192cu.ko

2. 启动wlan0

ifconfig -a 会发现wlan0
ifconfig wlan0 192.168.2.1

ifconfig wlan0 up

3.设置8192为client

#wpa_supplicant 服务端程序，使用配置脚本wpa_supplicant.conf 自动连接到ap
#wpa_cli用于交互的客户端程序，比如可以用于手动连接到某个ap
./wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf &
#自动获取ip地址
udhcpc -i wlan0

#/etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=root
#ap_scan=1
network={
ssid="mywlan"
psk="1234567890"proto=WPA2key_mgmt=WPA-PSK
pairwise=TKIP
group=TKIPpriority=20
}

4.设置8192为ap：

#hostapd 服务端程序，使用脚本hostapd.conf自动配置信息，配置文件hostapd.conf
#hostapd_cli用于交互的客户端程序,比如
#hostpd_cli all_sta列出所有的已连接的client
#iwlist wlan0 scan ; cat /proc/net/rtl819xC/wlan0/best_channel 查看最好的channel
./hostapd ./hostapd.conf -B
#启动dhcp服务器：
#配置文件位于/etc/dhcpd.conf
dhcpd wlan0

}

直接使用无线管理工具 wireless_tools ，也能实现8192与远端 AP 的链接以及无线网络的通信。
其中， iwconfig 用来配置无线网卡， iwlist 用来搜索无线网络。
ifconfig wlan0 192.168.2.2 netmask 255.255.254.0 up /*打开网络*/
iwlist wlan0 scanning /*不知道无线网络名时搜索网络名 */
iwconfig wlan0 essid “mywlan”/*指定无线网络名 dlink*/
iwconfig wlan0 key 1234567890 /*指定访问密码*/
