Native Wifi 简介

    是提供给软件开发者来开发windows 无线管理的一系列API。编程人员可以通过这些函数来进行相关的无线管理，当然我们还可以通过netsh终端命令来管理，这对于非编程人员就可以简单的实现，具体可以查阅相关资料去了解。

    API如下：

• WLAN_NOTIFICATION_CALLBACK
• WlanAllocateMemory
• WlanCloseHandle
• WlanConnect
• WlanDeleteProfile
• WlanDisconnect
• WlanEnumInterfaces
• WlanExtractPsdIEDataList

无线的连接相关知识

    从windows的无线网络属性设置窗口来对比，在API编程中，同样有个配置文件来设置这些属性的，那就是profile文件，通过编写xml文件来设置相关属性。

WLAN_profile Schema Elements [xml配置文件编写格式]：

• WLANProfile
  • name (WLANProfile)
  • SSIDConfig (WLANProfile)
    • SSID (SSIDConfig)
      • hex (SSID)
      • name (SSID)
    • nonBroadcast (SSIDConfig)
  • connectionType (WLANProfile)
  • connectionMode (WLANProfile)
  • autoSwitch (WLANProfile)
  • MSM (WLANProfile)
    • connectivity (MSM)
      • phyType (connectivity)
    • security (MSM)
      • authEncryption (security)
        • authentication (authEncryption)
        • encryption (authEncryption)
        • useOneX (authEncryption)
        • FIPSMode (authEncryption)
      • sharedKey (security)
        • keyType (sharedKey)
        • protected (sharedKey)
        • keyMaterial (sharedKey)
      • keyIndex (security)
      • PMKCacheMode (security)
      • PMKCacheTTL (security)
      • PMKCacheSize (security)
      • preAuthMode (security)
      • preAuthThrottle (security)
  • IHV (WLANProfile)
    • OUIHeader (IHV)
      • OUI (OUIHeader)
      • type (OUIHeader)
    • connectivity (IHV)
    • security (IHV)
