Native Wifi 簡介

是提供給軟件開發者來開發windows 無線管理的一系列API。編程人員能夠經過這些函數來進行相關的無線管理，固然咱們還能夠經過netsh終端命令來管理，這對於非編程人員就能夠簡單的實現，具體能夠查閱相關資料去了解。

API以下：

WlanUIEditProfile

無線的鏈接相關知識

從windows的無線網絡屬性設置窗口來對比，在API編程中，一樣有個配置文件來設置這些屬性的，那就是profile文件，經過編寫xml文件來設置相關屬性。

WLAN_profile Schema Elements [xml配置文件編寫格式]：

WLANProfile

Wireless Profile Samples[無線配置文件例程]

例如常見的路由器，安全類型爲WPA2-PSK的xml配置文件以下（有密碼）：

<?xml version="1.0" encoding="US-ASCII"?>
<WLANProfile xmlns="http://www.microsoft.com/networking/WLAN/profile/v1">
<name>SampleWPA2PSK</name>
<SSIDConfig>
<SSID>
<name>SampleWPA2PSK</name>
</SSID>
</SSIDConfig>
<connectionType>ESS</connectionType>
<connectionMode>auto</connectionMode>
<autoSwitch>false</autoSwitch>
<MSM>
<security>
<authEncryption>
<authentication>WPA2PSK</authentication>
<encryption>AES</encryption>
<useOneX>false</useOneX>
</authEncryption>

<sharedKey>

<keyType>passPhrase</keyType>

<protected>false</protected>

<keyMaterial>  </keyMaterial>
</sharedKey>

</security>
</MSM>
</WLANProfile>

注：

【加密類型設置】
