adb命令设置wifi上网

Android系统中对于WIFI的设置集成到了“设置”中，其实跟手动设置差不多。这里介绍下如何手动连接WIFI，以方便以后调试WIFI。

第一步要做的就是要加载WIFI模块驱动了。当然如果你的WIFI是编译到内核里面的，就不需要的。我们的WIFI芯片用的是BCM4330，编译为模块。

insmod/system/lib/modules/kernel/drivers/net/wireless/bcm4330/bcm4330.kofirmware_path=/system/vendor/firmware/bcm4330.bin\nvram_path=/system/vendor/firmware/nvram.txt

这样驱动模块加载后，需要启动wpa_supplicant

root@android:/#wpa_supplicant-Dwext-iwlan0-C/data/system/wpa_supplicant-c/data/misc/wifi/wpa_supplicant.conf&

然后ps|grepwpa看看有没有起来，在wifi工作过程中，这个进程要始终都在的。

接着启动客户端wpa_cli进行配置并连接wifi热点

wpa_cliv0.8.x

其中/data/system/wpa_supplicant是刚刚启动wpa_supplicant的时候创建的一个套接字

接着进行搜索wifi

>scan

<3>CTRL-EVENT-SCAN-RESULTS

查看搜到的有哪些热点

接着设置wifi，就连接Dept_driver这个热点吧

>add_net
3
>set_net3ssid"Dept_driver"
OK

Dept_driver的加密方式是WPA2-PSK

>set_net3psk"password"
OK
>select_net3
OK

这样，就都设置好了，接着用dhcpd分配一个IP地址

这样就完成了。可以上网了。
