进入开发板后进行相关配置：

mount -t nfs -o nolock,vers=2 192.168.7.1:/work/nfs_root /mnt

iw dev wlan0 scan 

无密码连接：

iw wlan0 connect answer

ping 192.168.43.1

有密码连接：

iw wlan0 connect answer keys d:0:baiwenwang123

iw dev wlan0 link  //查看连接状态

ping 192.168.43.1

iw wlan0 disconnect

wpa_supplicant配置：

tar xzf wpa_supplicant-2.0.tar.gz

cd wpa_supplicant-2.0/wpa_supplicant/

vi /etc/plaintext.conf

mkdir -p /var/run/wpa_supplicant

①(OPEN)无线连接

ifconfig wlan0 up

wpa_supplicant -B -c/etc/plaintext.conf -iwlan0

wpa_cli -iwlan0 status     //查看状态

②(WEP-psk)有线连接

mkdir -p /var/run/wpa_supplicant     //一个目录,用于wpa_supplicant和wpa_cli的socket通信

ifconfig wlan0 up 

ps

kill之前的进程

wpa_supplicant -B -c/etc/wep.conf -iwlan0

wpa_cli -iwlan0 status

另:

wpa_cli可工作于"命令模式" 和"交互模式"

③设置多个无线网络
