Wi-Fi是现代计算机的命脉，但有时连接到Wi-Fi的选项不会出现在Windows 11（或 Windows 10！）中。这使得在没有电缆的情况下无法连接到 Internet 或LAN资源。

以下是一些最有可能解决Wi-Fi问题并让您立即恢复在线的提示，从最好的通用故障排除提示开始。

1.重启你的电脑

没错，只要重启你的电脑。在许多情况下，任何无线网络异常都会在重启后神秘地消失。

2. 飞行模式是否开启？

Windows 11 具有飞行^(Airplane)或“飞行”模式设置，可关闭计算机上的每个无线电传输设备。这包括Wi-Fi和蓝牙^(Bluetooth)，因此值得检查您是否不小心将计算机切换到飞行^(Airplane)模式。

您可以按Windows + A或左键单击通知区域中的扬声器^(speaker)。

飞行模式按钮^{(Flight mode button)}不应亮起。如果是，请单击或点击一次。

3.运行网络疑难解答

Windows 11 有许多内置的疑难解答程序，可以自动检测和修复常见问题，而无需借助命令提示符^{(Command Prompt)}。您可以像这样使用网络疑难解答^{(Network Troubleshooter)}：

1. 打开开始菜单^{(Start Menu)}。
2. 选择设置齿轮^{(Settings Cog)}以打开设置^(Settings)。

1. 开放系统^(System)。
2. 打开疑难解答^{(Troubleshoot)}。

1. 接下来选择其他^(Other) 疑难解答^{(Troubleshooters)}。

1. 选择Internet 连接^{(Internet Connections)}旁边的运行^(Run)。

现在选择解决您的互联网连接问题^{(troubleshoot your internet connection)}的选项，然后按照屏幕上的说明进行操作。

它会让您知道它发现的任何问题以及是否可以解决这些问题。

4.引导进入安全模式^{(Boot Into Safe Mode)}（或使用以太网^{(Use Ethernet)}）

某些故障排除步骤可能需要互联网连接，或者您可能需要立即上网并稍后修复Wi-Fi 。有两种方法可以做到这一点。

首先，您可以将Windows 11^{(Windows 11)}引导至安全模式^{(Safe Mode)}。在此模式下启动时不会加载任何第三方应用程序，并且Windows会使用通用网络适配器驱动程序。如果您的 Wi-Fi 在安全模式下^{(Safe Mode)}工作，那么您的问题很可能与驱动程序有关，您可能需要更新驱动程序。前往如何以安全模式启动 Windows 11 以^{(How to Start Windows 11 in Safe Mode)}获取具体说明。

您的第二个选择是切换到以太网^(Ethernet)连接。将以太网^(Ethernet)电缆从最近的插座连接到您的 Windows 11 电脑。

5. 确保启用了 Wi-Fi

您的Wi-Fi是否首先打开？有多种方法可以关闭它。首先^(First)，在Windows 11本身中，您可以选择通知区域中的快速设置按钮。这将显示Windows中的^(Windows)Wi-Fi切换开关。打开它，看看事情是否恢复正常。

如果您使用的是笔记本电脑，那么您将在计算机侧面有一个硬件开关或用于Wi-Fi功能的键盘快捷键。如果在BIOS级别禁用Wi-Fi ， Windows将无法使用硬件。

如果有，您必须查看笔记本电脑的手册以了解按钮的位置。键盘^(Keyboard)Wi-Fi 切换通常通过按住Fn 键^{(Fn key)}，然后按带有 Wi-Fi 图标的相应键来操作。

6. 启用您的 Wi-Fi 连接

由于某种原因，您的 Wi-Fi 连接可能在Windows 11本身中被禁用。^{(Windows 11)}以下是检查和解决问题的方法：

1. 使用 Windows 键打开开始菜单。^{(Start Menu)}
2. 键入控制面板^{(Control Panel)}，然后按Enter。

1. 转到网络和 Internet^{(Network and Internet )} >网络和共享中心^{( Network and Sharing Center)}。

1. 选择更改适配器设置^{(Change adapter settings)}。

在这里，您将看到所有网络连接和连接的调制解调器。

查找列出的正确网络适配器的 Wi-Fi 连接。在大多数系统中，只有一个。如果它变灰并标记为“禁用”，只需右键单击它并选择启用^(Enable)。

7. 检查您的 Wi-Fi适配器是否^{(Adapter Is Plugged)}已插入

如果您使用的是基于 USB 的WiFi适配器（如果您使用的是台式机系统），请确保它已正确插入。

您可能还想在另一台计算机上尝试它以确保它仍然有效。尝试使用不同的USB端口。以防端口本身出现问题。

8.在设备管理器中检查您的^{(Device Manager)}网络适配器^{(Network Adapter)}

设备管理器^{(Device Manager)}应用程序向您显示计算机中所有硬件的列表以及它们是否正常工作。

1. 打开开始菜单^{(Start Menu)}。
2. 键入设备管理器^{(Device Manager)}。
3. 从搜索结果中打开设备管理器。^{(Device Manager)}

您可能需要双击计算机类别才能将其展开。

搜索网络适配器部分，然后展开它以查看所有网络适配器。

在网络适配器列表中查找您的 Wi-Fi 适配器，并检查其上是否有警告图标，例如黄色感叹号。右键单击适配器并检查其属性以获取特定的错误消息。

如果设备管理器中完全没有适配器，则表明存在硬件级别的问题或未检测到适配器的原因。如果适配器仅在安全模式^{(Safe Mode)}下工作，则可能与软件或驱动程序有关。

如果适配器的图标上有一个红叉，请右键单击它并选择Enable。如果这不可能，您可以通过右键单击设备并选择卸载来卸载设备。然后重新启动计算机以再次检测硬件。

9. 更新、回滚^{(Roll Back)}或重新安装您的 Wi-Fi 驱动程序

大多数情况下，您的 Wi-Fi 停止工作是因为硬件驱动程序出错。您必须从制造商的网站下载并安装最新的驱动程序，在设备管理器下的适配器属性中使用驱动程序回滚，或者完全卸载驱动程序并重新安装最新版本或最后一个可用的版本。

10.使用“重置网络”功能

虽然重置或重新安装Windows是解决大多数问题的有效方法，但对于像不稳定^(Windows)的 Wi-Fi^(Wi-Fi)这样的小问题来说，这有点矫枉过正。幸运的是，您^(Luckily)只能^{(only )}重置网络设置：

1. 打开开始菜单^{(Start Menu)}。
2. 选择设置齿轮^{(Settings Cog)}以打开设置应用程序^{(Settings app)}。
3. 选择网络和互联网^{(Network and Internet)}。
4. 现在选择高级网络设置^{(Advanced network settings)}。

1. 最后，选择网络重置^{(Network reset)}，然后立即重置^{(reset now)}。

这将重置您的所有网络和适配器设置。重新启动计算机以确保重置已生效。如果您有任何特殊的网络配置，例如VPN 连接^{(VPN connection)}、代理服务器或自定义DNS设置，则必须重新设置它们。

11. 如果没有显示特定的 Wi-Fi 网络

当您搜索特定 Wi-Fi 选项未显示的原因时，您可能会发现这篇文章，即使其他选项显示。这里最简单的解决方法是重置路由器和您的计算机。

您也可以登录路由器的设置页面，确保“广播 SSID”已打开，以便网络可见。

如果网络正在显示，但您无法连接到它，请尝试忘记它：

1. 打开开始菜单^{(Start Menu)}。
2. 选择设置齿轮^{(Settings Cog)}。
3. 选择Network & Internet，然后选择Wi-Fi。

1. 选择管理已知网络^{(Manage known networks)}。

1. 选择Wi-Fi网络，然后选择忘记^(Forget)。

您必须重新输入网络密码，但在许多网络设置已损坏或更改的情况下，忘记网络将解决问题。

12. 更新视窗

Microsoft会定期更新Windows 11 的新功能、错误修复和性能增强。不幸的是，世界上有这么多计算机，由于Windows更新，一些计算机不可避免地会出现问题。

如果您的 Wi-Fi 问题是在最近更新后开始的，请检查网络是否有其他用户也遇到此问题的迹象。如果问题看起来与更新有关，请查看如何卸载和重新安装 Windows 更新^{(How to Uninstall and Reinstall Windows Updates)}。然后删除该更新并检查解决问题的更新。

13.在组策略编辑器^{(Group Policy Editor)}中启用 Wi-Fi图标^(Icon)

如果您使用的是Windows 11 Pro并且您的 Wi-Fi 图标完全丢失，则可能是编辑器中的设置已更改。如果您的计算机由您工作的公司中的某个人管理，您需要请他们检查。再说一次，如果您有权联系 IT 部门，您应该首先要求他们解决您的 Wi-Fi 问题！

1. 按Windows + R打开“运行”对话框^{(Run dialog box)}。
2. 键入gpedit.msc并按Enter。

1. 在组策略编辑器^{(Group Policy Editor)}中，转到用户配置^{(User Configuration)}。
2. 现在选择Administrative Templates -> Start Menu and Taskbar。
3. 查找删除网络图标^{(Remove the networking icon)}并将其打开。

1. 如果尚未禁用，请选择Window左上角的Disabled 。

1. 选择OK并重新启动计算机^{(restart your computer)}。

如果此策略已被禁用，请不要在组策略编辑器^{(Group Policy Editor)}中更改或保存任何其他内容，只需将其关闭并尝试不同的解决方案。

无需再担心无线问题。

这是一长串修复程序，但除非您的 Wi-Fi 出现真正奇怪的问题，否则您应该再次拥有正常工作的无线连接。要使 Wi-Fi 连接更好，请查看10 种增强弱 WiFi 信号的方法^{(10 Ways To Boost a Weak WiFi Signal)}。

13 Fixes When Windows 11 Wi-Fi Not Showing Up

Wi-Fi is the lifeblood of modern computers, but sometimes the option to connect to Wi-Fi doesn’t show up in Windows 11(or Windows 10!). This makes it impossible to connect to the internet or LAN resources without a cable.

Here are some of the most likely tips to fix Wi-Fi problems and get you back online in no time, starting with the best universal troubleshooting tip of all.

1. Reboot Your PC

That’s right, just restart your computer. In many cases, any wireless network weirdness mysteriously goes away after a reboot.

2. Is Airplane Mode On?

Windows 11 has an Airplane or “flight” mode setting which turns off every radio-transmission device on your computer. That includes Wi-Fi and Bluetooth, so it’s worth checking that you haven’t accidentally toggled the computer into Airplane mode.

You can press Windows + A or left-click on the speaker in the notification area.

The Flight mode button should not be lit up. If it is, click or tap on it once.

3. Run the Network Troubleshooter

Windows 11 has a number of built-in troubleshooters that automate the detection and repair of common issues without resorting to the Command Prompt. You can use the Network Troubleshooter like this:

1. Open the Start Menu.
2. Select the Settings Cog to open Settings.

1. Open System.
2. Open Troubleshoot.

1. Next select Other Troubleshooters.

1. Select Run next to Internet Connections.

Now select the option to troubleshoot your internet connection and follow the on-screen instructions.

It will let you know of any issues it finds and whether it could fix them.

4. Boot Into Safe Mode (or Use Ethernet)

Some troubleshooting steps may require an internet connection or perhaps you need to get on the internet now and fix the Wi-Fi later. There are two ways to accomplish this.

First, you can boot Windows 11 into Safe Mode. No third-party apps are loaded at startup in this mode, and Windows falls back on a generic network adapter driver. If your Wi-Fi works in Safe Mode, there’s a good chance your issues are driver-related, and you may need to update drivers. Head over to How to Start Windows 11 in Safe Mode for specific instructions.

Your second option is to switch over to an Ethernet connection. Run an Ethernet cable from the nearest outlet to your Windows 11 PC.

5. Ensure Wi-Fi Is Enabled

Is your Wi-Fi toggled on in the first place? There are a number of ways it could be toggled off. First, in Windows 11 itself, you can select the quick settings button in the notification area. This will reveal the Wi-Fi toggle switch in Windows. Toggle it on and see if things go back to normal.

If you’re using a laptop, then you’ll either have a hardware switch on the side of the computer or a keyboard shortcut for Wi-Fi functionality. If Wi-Fi is disabled at the BIOS level, Windows can’t use the hardware.

You’ll have to check your laptop’s manual for the button’s location if any. Keyboard Wi-Fi toggles are usually operated by holding the Fn key and then pressing the corresponding key with a Wi-Fi icon on it.

6. Enable Your Wi-Fi Connection

Your Wi-Fi connection may be disabled in Windows 11 itself for some reason. Here’s how to check for and fix the issue:

1. Open the Start Menu with the Windows key.
2. Type Control Panel and then press Enter.

1. Go to Network and Internet > Network and Sharing Center.

1. Select Change adapter settings.

Here you’ll see all of your network connections and connected modems.

Look for a Wi-Fi connection listed for the correct network adapter. In most systems, there will be only one. If it’s grayed out and labeled “Disabled,” simply right-click on it and select Enable.

7. Check if Your Wi-Fi Adapter Is Plugged In

If you’re using a USB-based WiFi adapter, which is likely if you’re on a desktop system, make sure it’s plugged in correctly.

You may also want to try it on a different computer to ensure it still works. Try using a different USB port as well. In case there’s something amiss with the port itself.

8. Check Your Network Adapter in Device Manager

The Device Manager application shows you a list of all the hardware in your computer and whether they work correctly or not.

1. Open the Start Menu.
2. Type Device Manager.
3. Open Device Manager from the search results.

You may have to double-click the computer category to expand it.

Search for the network adapters section, and expand that to see all of your network adapters.

Look for your Wi-Fi adapter in the list of network adapters and check whether it has a warning icon on it, such as a yellow exclamation mark. Right-click on the adapter and check its properties for specific error messages.

If the adapter is completely absent from the device manager, it indicates a hardware-level issue or why the adapter isn’t being detected. If the adapter works in Safe Mode only, it may be related to software or drivers.

If the adapter has a red cross through its icon, right-click on it and select Enable. If that’s not possible, you can uninstall devices by right-clicking on them and selecting uninstall. Then reboot your computer to detect the hardware again.

9. Update, Roll Back or Reinstall Your Wi-Fi Drivers

Most often, your Wi-Fi stops working because the hardware driver has gone wrong. You’ll either have to download and install the latest driver from the manufacturer’s website, use driver roll-back in the adapter’s properties under device manager, or uninstall the driver completely and reinstall the newest version or the last version that worked.

10. Use the “Reset Network” Function

While resetting or reinstalling Windows is an effective way to solve most problems, it’s a bit overkill for something minor like wonky Wi-Fi. Luckily you can reset only the network settings:

1. Open the Start Menu.
2. Select the Settings Cog to open the Settings app.
3. Choose Network and Internet.
4. Now choose Advanced network settings.

1. Finally, choose Network reset and then reset now.

This will reset all of your network and adapter settings. Restart your computer to make sure the reset has taken effect. If you have any special network configurations, such as a VPN connection, proxy server, or custom DNS settings, you’ll have to set them up again.

11. If a Specific Wi-Fi Network Isn’t Showing Up

There’s a chance you’ve found this article when you were searching for reasons why a specific Wi-Fi option isn’t showing up even though others do. The easiest fix here is to reset the router and your computer for good measure.

You can also log in to the router’s settings page and make sure that “broadcast SSID” is switched on so that the network is visible.

If the network is showing up, but you can’t connect to it, try forgetting it:

1. Open the Start Menu.
2. Select the Settings Cog.
3. Choose Network & Internet, then choose Wi-Fi.

1. Select Manage known networks.

1. Choose the Wi-Fi network, and then choose Forget.

You’ll have to re-enter the password for the network, but in many cases where network settings have become corrupted or changed, forgetting the network will solve the problem.

12. Update Windows

Microsoft regularly updates Windows 11 with new features, bug fixes, and performance enhancements. Unfortunately, there are so many computers out in the world that inevitably some computers will develop problems thanks to a Windows update.

If your Wi-Fi issues started after a recent update, check the web for any indication that other users are also experiencing this issue. If it looks like the problem is related to an update, check out How to Uninstall and Reinstall Windows Updates. Then remove that update and check for updates that resolve the issue.

13. Enable the Wi-Fi Icon in the Group Policy Editor

If you’re using Windows 11 Pro and your Wi-Fi icon is missing altogether, it might be that a setting in the editor has changed. If your computer is administered by someone in the company you work for, you’ll need to ask them to check. Then again, if you have access to an IT department you should ask them to fix your Wi-Fi issue in the first place!

1. Press Windows + R to open the Run dialog box.
2. Type gpedit.msc and press Enter.

1. In the Group Policy Editor, go to User Configuration.
2. Now select Administrative Templates -> Start Menu and Taskbar.
3. Look for Remove the networking icon and open it.

1. Select Disabled in the top left of the Window, if it wasn’t disabled already.

1. Select OK and restart your computer.

If this Policy was already disabled, don’t change or save anything else in the Group Policy Editor, just close it and try a different solution.

No More Wireless Worries.

This is a long list of fixes, but you should have a working wireless connection again unless something genuinely odd has gone wrong with your Wi-Fi. To make that Wi-Fi connection even better, check out 10 Ways To Boost a Weak WiFi Signal.
