1.板子起来后，输入ifconfig -a查看eth0
2.关闭eth0：ifconfig eth0 down
3.wifi命令行联网
mkdir -p /var/run
wpa_supplicant -B -i wlan0 -c /misc/wifi/wpa_supplicant.conf
/ # cat /misc/wifi/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
update_config=1
network={
ssid="JNKJ_PHONE"
psk="12345678"
}
network={
ssid="JNKJ1"
psk="Jnkj3608"
}
/ # wpa_supplicant -B -i wlan0 -c /misc/wifi/wpa_supplicant.conf
Successfully initialized wpa_supplicant
rfkill: Cannot open RFKILL control device
nl80211: kernel reports: Registration to specific type not supported
rfkill: Cannot get wiphy information

4.udhcpc获取IP
udhcpc -i wlan0 -s /etc/init.d/udhcpc.script
5./ # ping www.baidu.com

二 WAP模式
/customer # ./wifiMngTest
wap k2 12345678
wap
