不同网络认证方式设置
1）open(开放式认证方式，分为):
wpa_cli -iwlan0 set_network 0 ssid '"wlan"'(PS:wlan是无线的ssid号，外面是一对双引号，然后再外面是一对单引号)
wpa_cli -iwlan0 set_network 0 key_mgmt NONE
2）wep（分为开放式和共享式）:
wpa_cli -iwlan0 set_network 0 ssid '"wlan"'
wpa_cli -iwlan0 set_network 0 key_mgmt NONE
wpa_cli -iwlan0 set_network 0 wep_key0 '"wlan_key"'
如果是共享式,还需要配置：wpa_cli -iwlan0 set_network 0 auth_alg SHARED(默认是开放式，可以不配置)
3)WPA/WPA2-Personal认证方式：
wpa_cli -iwlan0 set_network 0 ssid '"wlan"'
wpa_cli -iwlan0 set_network 0 key_mgmt WPA-PSK
wpa_cli -iwlan0 set_network 0 proto WPA(WPA2)
wpa_cli -iwlan0 set_network 0 pairwise TKIP(CCMP)
wpa_cli -iwlan0 set_network 0 group TKIP(CCMP)
wpa_cli -iwlan0 set_network 0 psk '"wlan_password"'
4)WPA/WPA2-Enterprise认证方式：
wpa_cli -iwlan0 set_network 0 ssid '"wlan"'
wpa_cli -iwlan0 set_network 0 key_mgmt WPA-EAP
wpa_cli -iwlan0 set_network 0 pairwise TKIP(CCMP)
wpa_cli -iwlan0 set_network 0 group TKIP(CCMP)
wpa_cli -iwlan0 set_network 0 eap PEAP
wpa_cli -iwlan0 set_network 0 identity '"username"'
wpa_cli -iwlan0 set_network 0 password '"password"'
如果是WPA2-Enterprise认证：需要设置proto：wpa_cli -iwlan0 set_network 0 protoWPA2
