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.ko firmware_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|grep wpa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
130|root@android:/ # wpa_cli -p/data/system/wpa_supplicant -iwlan0
wpa_cli v0.8.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

接着设置wifi,就连接Dept_driver这个热点吧

OK

Dept_driver的加密方式是WPA2-PSK

OK

这样,就都设置好了,接着用dhcpd分配一个IP地址
root@android:/ # dhcpcd wlan0                                                  
dhcpcd[3940]: version 5.2.10 starting

dhcpcd[3940]: wlan0: rebinding lease of 192.168.1.216
dhcpcd[3940]: wlan0: acknowledged 192.168.1.216 from 192.168.1.1 `�'
dhcpcd[3940]: wlan0: leased 192.168.1.216 for 7200 seconds

           inet6 addr: fe80::aee8:7bff:fe89:d3c0/64 Scopeink

           RX packets:6637 errors:0 dropped:25 overruns:0 frame:0
           TX packets:4357 errors:0 dropped:0 overruns:0 carrier:0

           RX bytes:3825961 (3.6 MiB)  TX bytes:704832 (688.3 KiB)
这样就完成了。可以上网了。
