1.列出当前网卡：SetupDiEnumDeviceInfo
2.找出当前无线网卡的名字（用natvie wifi api）
3.卸载\安装此驱动
问题：
log为：SetupDiSetClassInstallParams failed. -536870347

一些常见错误解决
一、
从错误返回值入手。
-536870347，用windows自带计算器，选择程序员模式，将此十进制转换为16进制为E0000235.
用此错误号搜索，就是大名鼎鼎的32位程序跑在64位系统中报错。
虽然我用的64位win8下VS编译的程序，但是编译选项中仍然是WIN32程序。那么我们只需要修改成x64编译即可，操作如下。
BUILD-->Configuration Manager...-->找到要修改的project，将platform选择为x64.
如果没有，说明没有添加x64编译项，接着上面，在platform中选择<New...> -->New platform下选x64-->OK.
二、
编译64位程序，运行之。
仍然报错，返回值是5.ACCESS_DENIED.
权限不够，我们需要申请高权限。如下申请Admin权限：
你项目的Properties-->Linker-->Manifest File-->UAC Execution Level选requireAdministrator。
三、
继续运行。卸载无线网卡驱动成功。
但是上一篇的程序仍然有个问题，由于驱动卸载了，就不能用wlan api得到无线网卡名称，
所以程序加载无线网卡驱动就会失败。
我们可以用关键字“Wireless Network Adapter”来查找无线网卡，省掉使用wlan api那一步。
