wl12xx移植
关于wpa_supplicant:
用到wpa_cli命令
wpa_cli -iwlan0
add_network // wlan0 是无线网络设备的名字，增加一个网络,会返回一个数字，假设为1
set_network 1 ssid '"……"' //这里ssid是要连接的网络名，注意 后面是单引号+双引号
set_network 1 psk '"……"' //这里psk是密码
enable_network 1
select_network 1
save_config
dhclient -r wlan0
dhclient wlan0
//注意可能wlan0是down的状态，有时需要 ifconfig wlan0 up
或者/etc/init.d/networking restart
wpa_cli -iwlan0 scan
wpa_cli -iwlan0 scan_result
wpa_cli -iwlan0 status
sudo ifconfig wlan0 up
sudo ifconfig wlan0 192.168.1.126
应该能ping通局域网
wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -B
wpa_supplicant.conf 可以在wpa_supplicant源码目录中找到：如下
cd wpa_supplicant
find -name *.conf ，不同的conf对用不同的加密方式
ps -aux |grep "wpa_supplicant"后会看到(系统默认运行的wpa_supplicant命令)
/sbin/wpa_supplicant -B -P /run/sendsigs.omit.d/wpasupplicant.pid -u -s -O /var/run/wpa_supplicant
//wpa_wpa2.conf文件
ctrl_interface=/var/run/wpa_supplicant
network={
ssid="网络名"
psk = "密码"
}
重启网络：/etc/init.d/networking restart
添加路由：route add default gw 192.168.1.1
添加DNS ：/etc/resolv.confnameserver 192.168.1.1
sudo killall wpa_supplicant
会提示
Delete '/var/run/wpa_supplicant/wlan0' manually if it is not used anymore
执行sudo rm /ver/run/wpa_supplicant
就可以成功执行sudo wpa_supplicant -Dwext -iwlan0 -c/wpa_wpa2.conf -B
不加 -B 会打印如下内容
