在使用WiFI构建的RPI3上，WiFi会在一段时间后断开连接 [英] WiFi disconnects after a while on RPI3 with build in WiFI

问题描述

我在RPI上使用WiFI时遇到问题。 WiFi工作正常，但过了一段时间后，主板再也无法访问。谷歌搜索我看到它可能与节电设置做一些事情。我可以找到针对Debian或其他Linux变种的补丁，
但是如何在运行Windows 10 IOT核心的RPI 3上禁用WiFI模块的省电？

Hi, I having problems with using WiFI on a RPI. The WiFi works fine but after a while the board is not accessible anymore. Googling around i see that it has probably to do something with power save settings. I can find fixes for Debian or other Linux variants, but how can i disable power savings for the WiFI module on the RPI 3 running Windows 10 IOT core?

Hi, PeterL67

   在实现现代备用电源模型的Windows硬件平台中，当平台处于现代备用电源状态时，Wi-Fi设备保持与网络的连接。请参阅

现代备用平台的Wi-Fi电源管理。

    In a Windows hardware platform that implements the modern standby power model, the Wi-Fi device maintains its connection to the network while the platform is in the modern standby power state. Please refer to Wi-Fi power management for modern standby platforms.

   您可以使用
powercfg   cmdlet用于控制电源方案。

    You can use powercfg cmdlet to control power schemes.

    1.首先，使用" powercfg / Q"。 查询无线适配器设置的省电模式。您将得到如下结果：

    1. Firstly, use "powercfg /Q" to query the Power Saving Mode of Wireless Adapter Settings. You will get the result as below:

  Subgroup GUID: 19cbb8fa-5279-450e-9fac-8a3d5fedd0c1  (Wireless Adapter Settings)
    Power Setting GUID: 12bbebe6-58d6-4636-95bb-3217ef867c1a  (Power Saving Mode)
      Possible Setting Index: 000
      Possible Setting Friendly Name: Maximum Performance
      Possible Setting Index: 001
      Possible Setting Friendly Name: Low Power Saving
      Possible Setting Index: 002
      Possible Setting Friendly Name: Medium Power Saving
      Possible Setting Index: 003
      Possible Setting Friendly Name: Maximum Power Saving
    Current AC Power Setting Index: 0x00000000
    Current DC Power Setting Index: 0x00000002

    2.其次，使用" powercfg / deletesetting 19cbb8fa-5279-450e-9fac-8a3d5fedd0c1 12bbebe6-58d6-4636-95bb-3217ef867c1a "
删除该设置。

    2. Secondly, use "powercfg /deletesetting 19cbb8fa-5279-450e-9fac-8a3d5fedd0c1 12bbebe6-58d6-4636-95bb-3217ef867c1a" to remove the setting.

     如果您想通过编程更改Wi-Fi设备的电源管理配置，可以使用 
Windows 硬件实验套件。但请注意
硬件兼容性。

     If you want to change the power-management configurations for the Wi-Fi device by programming, you can use  Windows Hardware Lab Kit. But please note the hardware compatibility.

最诚挚的问候，

Michael
