2. 配置ip地址：

#wpa_supplicant -Dwext -ieth0 -c /data/misc/wifi/wpa_supplicant.conf -B
命令解释：
        参数-B代表后台运行，-ieth0代表使用设备eth0，-Dwex代表网卡芯片是wex，-c指定配置文件。

查看配置
#wpa_cli -p /data/misc/wpa_supplicant
>status                                                                   bssid=00:00:00:00:00:00                                                         ssid=camct_backup                                                               id=0                                                                            pairwise_cipher=WEP-104                                                         group_cipher=WEP-104
key_mgmt=NONE
wpa_state=COMPLETED
配置ip:
#ifconfig eth0 192.168.177.33
之后再查看配置会看到 ip_address=192.168.177.33
