Android下同时使用WIFI与3G网络（二）
为了同时使用WiFi和3G网络，就要手动绕过Android的Framework层去打开WiFi功能，包括：
1、加载驱动
2、连接AP
3、使用dhcp服务获取ip地址
4、更改路由表
这4步在上一篇博文http://blog.csdn.net/roger__wong/article/details/8603275中已经详细说明了。
在三星Galaxy S GT-I8150上尝试加载驱动结果失败了，于是我就意识到对于不同手机的加载方法应该是不同的。
所以就写这么一篇文章说明不同手机的WiFi驱动的加载方法。
对于最简单的情况，如我的小米2，找到WiFi模块（/system/lib/modules/wlan.ko），使用insmod加载即可。
在三星手机上，模块名变成了dhd.ko，加载后使用netcfg无法看到WiFi网络接口，使用dmesg打印发现错误日志如下：
<4>[23138.975414] dhd_bus_start: dhdsdio_probe_download failed. firmware = nvra m =
貌似firmware和nvram为空。
这两个值在很多机型上都记录在wifi.conf（/system/etc/wifi/wifi.conf）中，全部内容如下：
FIRMWARE_LOADER=wlan_loader DRIVER_PROP_NAME=wlan.driver.status SUPPLICANT_NAME=wpa_supplicant SUPP_PROP_NAME=init.svc.wpa_supplicant MODULE_FILE=/proc/modules IFACE_DIR=/data/misc/wifi DRIVER_MODULE_NAME=dhd DRIVER_MODULE_TAG=dhd FIRMWARE_LOADER= SUPP_CONFIG_TEMPLATE=/system/etc/wifi/wpa_supplicant.conf SUPP_CONFIG_FILE=/data/misc/wifi/wpa_supplicant.conf DRIVER_MODULE_PATH=/etc/wifi/dhd.ko MFGDRV_MODULE_ARG=firmware_path=/system/etc/wifi/bcm4329_mfg.bin nvram_path=/sys tem/etc/wifi/nvram_mfg.txt iface_name=eth0 DRV_AP_MODULE_ARG=firmware_path=/system/etc/wifi/bcm4329_aps.bin nvram_path=/sys tem/etc/wifi/nvram_net.txt iface_name=eth0 DRIVER_MODULE_ARG=firmware_path=/system/etc/wifi/bcm4329_sta.bin nvram_path=/sys tem/etc/wifi/nvram_net.txt iface_name=eth0 DRIVER_APS_FIRMWARE_NAME=bcm4329_aps.bin DRIVER_STA_FIRMWARE_NAME=bcm4329_sta.bin INTERFACENAME=eth0 WAPI_SUPPORT=true SUPP_CONF_FILEPATH=/data/misc/wifi/ SUPP_WAPI_AS_CERT_FILE_PATH=/sdcard/external_sd/cert/ SUPP_WAPI_USER_CERT_FILE_PATH=/sdcard/external_sd/cert/ SUPPLICANT_STATUS=wlan.supplicant.status把其中的DRIVER_MOdULE_ARG里的内容加到insmod的参数里，即（注意双引号）：
insmod /system/lib/modules/dhd.ko "firmware_path=/system/etc/wifi/bcm4329_sta.bin nvram_path=/system/etc/wifi/nvram_net.txt iface_name=eth0"
使用这行命令来加载驱动就没有问题了。
不同的手机加载的命令会略微有差异，幸好有软件已经帮我们总结了很多手机的WiFi驱动加载命令，下面是一款wifitether软件的部分源码，其中源码里的wifiLoadCmd的值就是WiFi驱动的加载命令。
