在 Windows 11/10 笔记本电脑或带有WiFi适配器的台式机上配置WiFi连接后，预计它会在下次自动连接。但是，如果您注意到 Windows 11/10 在启动时没有连接到WiFi，并且您需要手动连接，那么这里是如何使其自动连接。

Windows 11/10在启动时无法连接到WiFi

这种行为可能有多种原因。因此，除非您最近更改了WiFi连接凭据，否则您可以通过以下方式使Windows 11/10自动连接到WiFi：

1. 选择加入自动连接
2. 禁用Wifi 适配器上的^{(Wifi Adapter)}省电^{(Power Saver)}选项
3. 调整 Wifi Adapter^{(Adjust Wifi Adapter)}电源管理设置
4. 删除 Wlansvc 文件。

确保^(Make)WiFi强度足以让笔记本电脑检测和连接。如果信号较弱，则可能需要靠近路由器。

1]选择加入自动连接

当您连接到WiFi连接时，有一个可用的复选框。当您选择它时，它会确保在下次找到它时自动连接到 wifi 连接。您可能忘记检查该选项。

• 单击^(Click)系统托盘中的Wifi 连接^{(Wifi Connection)}或Internet连接图标。
• 它将打开网络列表。连接到您想要的，然后选择它。
• 单击^(Click)属性^(Properties)链接以打开网络属性^{(Network Properties)}
• 在网络配置文件屏幕中，切换显示在范围内时自动连接的选项。^{(Connect automatically when in range.)}

下次启动计算机时，它会自动连接。

2]禁用Wifi适配器上的^{(Wifi Adapter)}省电^{(Power Saver)}选项

使用笔记本电脑时，Wifi 适配器上的^{(Wifi Adapter)}Battery Power Saver选项可以在不使用或睡眠模式时关闭Wifi 。这是如何更改它

• 双击^(Double)系统^(System)托盘中的电池图标。^{(Battery Icon)}然后单击电池设置^{(Battery Settings)}链接。
• 它将打开电池^(Battery)部分。接下来点击电源^(Power)和睡眠设置
• 在电源^(Power)和睡眠设置中，找到右侧的附加^(Additional)电源设置链接。单击^(Click)以打开电源选项^{(Power Options)}。
• 然后对于任何选定的计划，单击更改^(Change)计划设置 >更改^(Change)高级电源^(Power)设置。点击^(Click)打开。
• 在电源选项高级^{(Power Options Advanced)}设置窗口中，找到无线适配器^{(Wireless Adapter)}设置
• 展开^(Expand)，您将有选择；使用电池^(Battery)并已插入^(Plugged)。
• 默认值为中等省电^{(Medium Power Saving)}。您可以将其更改为Maximum Performance或Low Power Saving。同样，您可以将其应用于Plugged状态。

完成后，Wifi应该会自动连接到现有网络。

3]调整Wifi适配器^{(Adjust Wifi Adapter)}电源管理设置

• Use WIN + X + M打开设备管理器^{(Device Manager)}
• 展开^(Expand)网络^(Network)适配器列表，右键单击已安装的网络适配器并选择属性。
• 在电源管理下，取消选中^(Power)允许计算机关闭此设备以节省电源^{(allow the computer to turn off this device to save power.)}的复选框。

如果有的话，原因是电源管理，那么它将确保操作系统不会停止任何Wifi连接。但是，它通常在电池电量不足时发生。

4]删除Wlansvc文件

WLANSVC或WLAN 自动配置服务^{(WLAN Auto Config Service)}可帮助计算机发现并连接到无线网络。如果它存储现有网络的文件已损坏，则可能是一个问题。以下是刷新它的方法：

• ^(Type)在运行^(Run)提示中键入services.msc 并按Enter。
• 在服务^(Services)管理单元中，找到WLAN AutoConfig。
• 右键单击^{(Right-click)}，然后单击停止以停止服务。
• 使用文件资源管理器^{(File Explorer)}导航到 C:ProgramDataMicrosoftWlansvcProfilesInterfaces
• 删除里面的所有文件夹。
• 重新启动WLAN AutoConfig服务，然后重新连接到网络。

我会建议一些额外的提示。您可以尝试更新或重新安装网络驱动程序，^{(update or reinstall network drivers,)}运行Windows 网络疑难解答，或通过设备管理器重新删除和添加适配器。

我们希望这些提示有用，并且您能够清楚地理解它们。

Windows does not connect to WiFi on startup

Once yоu configure a WiFi сonnection on your Windows 11/10 laрtop or a desktop with a WiFi adapter, it is expected that it will automatically connect the next time. Hоwever, if you are noticing that Windows 11/10 does not connect to WiFі on stаrtup, and you need to connect manually, then here is how to make it automatically conneсt.

Windows 11/10 does not connect to WiFi on startup

There can be multiple reasons for this behavior. So unless you have changed the WiFi connection credentials recently, here is how you can make Windows 11/10 connect to WiFi automatically:

1. Opt-in for Auto connection
2. Disable Power Saver option on Wifi Adapter
3. Adjust Wifi Adapter power management settings
4. Delete Wlansvc Files.

Make sure that the WiFi strength is enough for the laptop to detect and connect. If you have a weak signal, then you may need to get closer to the router.

1] Opt-in for Auto connection

When you connect to a WiFi connection, there is a checkbox available. When you select it, it will make sure to automatically connect to the wifi connection next time it finds it. You may have forgotten to check the option.

• Click on the Wifi Connection or Internet connection icon in the system tray.
• It will open the list of networks. Connect to the one you want, and then select it.
• Click on the Properties link to open Network Properties
• In the network profile screen, toggle the option which says the Connect automatically when in range.

Next time you start your computer, and it will automatically connect.

2] Disable Power Saver option on Wifi Adapter

When using a laptop, Battery Power Saver option on Wifi Adapter can turn off Wifi when not in use or sleep mode.  Here is how to change it

• Double click on Battery Icon in System tray. Then click on the Battery Settings link.
• It will open the Battery section. Next click on Power and sleep settings
• In the Power and sleep settings, locate Additional power settings link in the right part. Click to open Power Options.
• Then for any selected plan, click on Change plan settings > Change advanced Power settings. Click to open.
• In the Power Options Advanced settings window, find Wireless Adapter settings
• Expand, and you will have options; On Battery and Plugged in.
• The default is Medium Power Saving. You can change it to Maximum Performance or Low Power Saving. The same, you can apply it for Plugged in the state.

Done that, the Wifi should automatically connect to the existing network.

3] Adjust Wifi Adapter power management settings

• Use WIN + X + M to open the Device Manager
• Expand the Network adapters list, and right-click on your installed network adapter and select Properties.
• Under Power management, uncheck the box which says allow the computer to turn off this device to save power.

If at all, the reason is power management, then it will make sure that the OS doesn’t stop any Wifi connection. However, it usually happens when in low battery.

4] Delete Wlansvc Files

WLANSVC or WLAN Auto Config Service helps computers to discover a wireless network, and connect to it. If the files where it stores existing networks are corrupt, then it can be a problem. Here is how you can refresh it:

• Type services.msc in the Run prompt and hit Enter.
• In the Services snap-in, locate WLAN AutoConfig.
• Right-click, and click on stop to stop the service.
• Using File Explorer navigate to C:\ProgramData\Microsoft\Wlansvc\Profiles\Interfaces
• Delete all the folders inside it.
• Restart the WLAN AutoConfig service, and then reconnect to networks again.

There are a few additional tips I would suggest. You can try to update or reinstall network drivers, run Windows Network Troubleshooter, or remove and add adapter again through the device manager.

We hope these tips were useful, and you were able to understand them clearly.
