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

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
