无论您是设置了新的Wi-Fi网络还是访问公共热点，当您的 Windows 10 笔记本电脑找不到您知道存在的Wi-Fi网络时，都会非常烦人。(Wi-Fi)
这是一个非常常见的问题，但不幸的是，它可能是由多种原因引起的。您的防病毒软件、Windows防火墙或网络适配器本身的任何内容都可能会阻止活动的 Wi-Fi 网络出现在您的可用网络列表中。
浏览本指南，从最简单的修复开始到更高级的修复，希望在您结束之前，您会看到Wi-Fi网络出现在列表中。
1.重置你的路由器
在您花费大量时间对 Windows 10 计算机无法看到Wi-Fi网络的原因进行故障排除之前，请首先确保该网络存在。
- 使用(Use)您家中的其他设备检查它们是否可以访问Wi-Fi网络。
- 尝试在另一台计算机上使用Wi-Fi 扫描仪(Wi-Fi scanner)查看所有可用网络。
- 如果其他设备看不到网络，请重新启动路由器(restart your router)以使网络再次正常工作。
一旦您通过其他设备确认Wi-Fi网络确实存在，请使用麻烦的Windows 10计算机再次测试访问它。如果它仍然不起作用，请继续执行下一步。
2.使用网络疑难解答
如果您的 Wi-Fi 网络适配器存在易于解决的问题，Windows 10网络疑难解答应该能够解决。这使它成为最好的尝试。
选择“开始”菜单，键入Settings，然后选择“设置”(Settings)应用。
在设置窗口中，选择更新和安全(Update & Security)。
在左侧导航菜单中选择疑难解答(Troubleshoot)，然后在右侧窗格中选择其他疑难解答。(Additional troubleshooters)

疑难解答向导将引导您完成步骤，因为它会检查最可能导致网络问题的各种适配器和系统设置。如果故障排除程序成功，请重新启动系统，您现在应该能够看到Wi-Fi网络。
如果找不到问题，则需要继续执行后续步骤。
3.重置您的网络适配器
尝试的第一件事是重置Wi-Fi(Wi-Fi)网络适配器，因为它最常解决问题。
这很容易做到。打开Windows 控制面板(Windows Control Panel)并选择网络和 Internet 部分(Network and Internet section)下的查看网络状态和任务(View network status and tasks)。
在左侧导航窗格中选择更改适配器设置。(Change adapter settings)
这将打开系统上所有可用网络适配器的列表。您将在左窗格中看到此列表。找到您正在使用的活动 Wi-Fi 适配器并右键单击它。从菜单中 选择禁用。(Disable)
这将完全禁用您的活动 Wi-Fi 适配器。它会重置所有缓存的数据，并完全断开您与任何网络的连接。等待一整分钟，然后重复上述过程。这次从菜单中选择启用。(Enable)
现在，当您在任务栏中选择 Wi-Fi 图标时，您应该会看到以前看不到的活动网络。
如果您仍然看不到它，那么您需要继续进行下一个故障排除步骤。
4.切换无线网络模式
如果运行网络的路由器未使用Wi-Fi适配器所使用的模式提供网络，则 Windows 10 电脑将无法看到Wi-Fi网络。要测试是否是这种情况，请尝试更改网络模式。
按照上述相同的步骤选择更改适配器设置(Change adapter settings)。再次右键单击您的 Wi-Fi 适配器并选择Properties。在Wi-Fi 属性(Wi-Fi Properties)窗口中，选择配置(Configure)按钮。
选择高级(Advanced)选项卡，在属性窗口中选择(Property)无线模式(Wireless Mode)，然后使用值(Value)下拉菜单选择无线模式。

当设备管理器(Device Manager)打开时，展开树中的网络适配器(Network adapters)。右键单击您的无线适配器并选择更新驱动程序(Update driver)。
这将启动驱动程序更新向导。选择浏览我的计算机以查找驱动程序(Browse my computer for drivers)。该向导将找到您最近下载的无线适配器驱动程序并尝试重新安装它。
您需要尝试此选项，因为您无法让向导自动在 Internet 上搜索驱动程序。更新驱动程序后，重新启动计算机并检查是否可以看到无线网络。
7. 重置 TCP/IP
另一个经常解决网络问题的有用技巧是手动重置所有TCP/IP这可以帮助清除任何可能干扰您的网卡查看可用网络的网络连接问题。
为此，请以管理员身份(as administrator)启动命令提示符。选择开始(Start)菜单，键入命令，然后右键单击命令(Command)应用程序。
在命令提示符窗口中，键入以下行并在每行之后按Enter。
- netsh int ip 重置
- netsh int tcp set heuristics disabled
- netsh int tcp 设置全局 autotuninglevel=disabled
- netsh int tcp 设置全局 rss=启用
运行所有这些命令后，重新启动计算机并再次测试 Wi-Fi 连接。
8.获取新的IP设置
您的 Windows 10 PC 无法找到您的 Wi-Fi 网络的问题实际上可能不是找到网络，而是建立连接。当您的计算机的 IP 地址与网络上已有的另一台设备发生冲突时，可能会发生这种情况。
当您长时间未连接到网络并且新设备接收到您的旧 IP 地址时，可能会发生这种情况。要查看这是否是原因，请尝试在命令提示符下释放和更新您的 IP 地址。
选择开始菜单，键入命令(command)，然后选择命令提示符(Command Prompt)应用。
在命令行中，键入ipconfig /release并按Enter。
在此命令之后的文本中，您将看到IPv4 IP地址变为空白。
接下来，在命令行中，键入ipconfig /renew并按Enter。
完成此命令后，您将看到IPv4 地址(IPv4 Address)字段中出现一个新的 IP 地址。
现在选择任务栏中的 Wi-Fi 图标，然后查看您的 Wi-Fi 网络现在是否显示。
9.暂时禁用杀毒软件
如果您已经走到了这一步，但仍然看不到您的Wi-Fi网络，则您的防病毒软件可能会阻止它。
要测试是否是这种情况，请暂时禁用防病毒保护。大多数防病毒应用程序的任务栏右侧都有一个图标。您通常可以右键单击此图标并选择暂停保护(Pause protection)。
或者，您可以打开防病毒应用程序并找到网络保护菜单。在此窗口中，通常有一个选项可以关闭网络保护。
禁用保护后，请检查您的 Wi-Fi 网络是否显示。
10.暂时禁用Windows防火墙(Windows Firewall)
如果这不起作用，请转向Windows 防火墙(Windows Firewall)作为可能的罪魁祸首。暂时关闭Windows 防火墙(Windows Firewall)进行测试。
选择开始菜单，键入防火墙(Firewall)，然后选择Windows Defender 防火墙(Windows Defender Firewall)。
在Windows Defender 防火墙(Windows Defender Firewall)应用中，选择左侧菜单中的打开或关闭 Windows Defender 防火墙。(Turn Windows Defender Firewall on or off)
这将打开一个窗口，您可以在其中自定义保护。在这两个部分下选择单选按钮以关闭 Windows Defender 防火墙。(Turn off Windows Defender Firewall)
选择确定(OK)，然后重新启动计算机。当它重新启动时，检查 Windows 10 现在是否可以找到您的 Wi-Fi 网络。
Windows 10找不到您的 Wi-Fi 网络(Find Your Wi-Fi Network)
如果你已经走到这一步，你只有几个其他的选择。您可能需要更换Wi-Fi网络适配器，因此如果您自己不知道如何更换，请联系计算机技术人员为您更换。
但是，在执行此步骤之前，请将您的计算机带到本地 Wi-Fi 热点(local Wi-Fi hotspot)并检查您的网络适配器是否可以看到另一个 Wi-Fi 网络。如果不能，则很可能是网络适配器出了问题，您应该更换它。
WiFi Network Not Showing Up or Can’t Find WiFi in Windows?
Whеther you’ve sеt up a new Wi-Fi network or you’re visiting a public hotspot, it can be very annoying when your Windows 10 laptop can’t find the Wi-Fi network that you know exists.
This is a very common problem, but unfortunately, it can be caused by a number of things. Anything from your antivirus software, Windows firewall, or the network adapter itself, may prevent the active Wi-Fi network from showing up in your list of available networks.
Walk through this guide, starting from the simplest fix to the more advanced ones, and hopefully before you get to the end you’ll see the Wi-Fi network show up in the list.
1. Reset Your Router
Before you spend a lot of time troubleshooting why your Windows 10 computer can’t see the Wi-Fi network, make sure the network exists in the first place.
- Use other devices in your home to check if they can access the Wi-Fi network.
- Try using a Wi-Fi scanner on another computer to view all available networks.
- If other devices can’t see the network, restart your router to get the network working again.
Once you’ve confirmed with other devices that the Wi-Fi network actually exists, test accessing it again with the troublesome Windows 10 computer. If it still doesn’t work, then move on to the next steps.
2. Use the Network Troubleshooter
If there’s an issue with your Wi-Fi network adapter that’s easy to resolve, the Windows 10 network troubleshooter should be able to do it. This makes it the best first thing to try.
Select the Start menu, type Settings, and select the Settings app.
In the Settings window, select Update & Security.
Select Troubleshoot in the left navigation menu, then select Additional troubleshooters in the right pane.
Scroll down the list of troubleshooters and select Network Adapter. Select the Run the troubleshooter button that appears.
The troubleshooter wizard will walk you through steps as it checks various adapter and system settings that are the most likely cause of your network issues. If the troubleshooter is successful, reboot your system and you should be able to see the Wi-Fi network now.
If it can’t find the issue, you’ll need to move on to the next steps.
3. Reset Your Network Adapter
The first thing to try, because it resolves the issue most often, is to reset the Wi-Fi network adapter.
This is easy to do. Open the Windows Control Panel and select View network status and tasks under the Network and Internet section.
Select Change adapter settings in the left navigation pane.
This will open a list of all available network adapters on your system. You’ll see this list in the left pane. Find the active Wi-Fi adapter that you’re using and right-click it. Select Disable from the menu.
This will completely disable your active Wi-Fi adapter. It’ll reset any data that was cached and completely disconnect you from any network. Wait a full minute and then repeat the process above. This time select Enable from the menu.
Now when you select the Wi-Fi icon in the taskbar, you should see the active network that you couldn’t see before.
If you still don’t see it then you’ll need to continue on to the next troubleshooting step.
4. Switch Wireless Network Mode
If the router that’s operating the network doesn’t provide a network using the mode that your Wi-Fi adapter is using, your Windows 10 PC won’t be able to see the Wi-Fi network. To test if this is the case, try changing the network mode.
Follow the same procedure above to select Change adapter settings. Right-click your Wi-Fi adapter again and select Properties. In the Wi-Fi Properties window, select the Configure button.
Select the Advanced tab, select Wireless Mode in the Property window, and then use the Value dropdown to select the wireless mode.
If your Wi-Fi adapter displays multiple modes in this dropdown, you should select the one with as many modes as possible. This will allow your adapter to “see” networks that are using any one of these modes. Select OK when you’re done.
Restart your computer and then check if you can now find the Wi-Fi network.
5. Disable IPv6 Protocol
In some cases, if you’ve enabled the IPv6 protocol on your system, it can cause issues when trying to connect to networks or the internet. Disabling this protocol often resolves issues like this.
To do this, use the same procedure as above to navigate to the Wi-Fi Properties window. Scroll down the connection items list and find Internet Protocol Version 6 (TCP/IPv6). Deselect the checkbox to the left of this option.
Select OK. Now restart your computer and check if the Wi-Fi network is now visible in the list of networks.
6. Update Your Network Driver
An outdated network driver can often lead to issues with the network card accessing any networks at all. For this reason, it’s always a good idea to make sure your network drivers are updated.
Launch Device Manager by right-clicking the Start menu and selecting Device Manager.
When the Device Manager opens, expand Network adapters in the tree. Right-click on your wireless adapter and select Update driver.
This will launch the driver update wizard. Select Browse my computer for drivers. The wizard will find the most recently downloaded driver for your wireless adapter and will attempt to reinstall it.
You’ll need to try this option since you can’t have the wizard search the internet automatically for drivers. Once the driver is updated, restart your computer and check if you can see the wireless network.
7. Reset TCP/IP
Another useful tip that often resolves networking issues is resetting all TCP/IP connections manually. This can help clear any network connection issues that may be interfering with your network card’s ability to view available networks.
To do this, launch the command prompt as administrator. Select the Start menu, type command, and right-click the Command app.
In the command prompt window, type the following lines and press Enter after each.
- netsh int ip reset
- netsh int tcp set heuristics disabled
- netsh int tcp set global autotuninglevel=disabled
- netsh int tcp set global rss=enabled
Once you’ve run all of these commands, restart your computer and test the Wi-Fi connection again.
8. Obtain New IP Settings
The problem with your Windows 10 PC not being able to find your Wi-Fi network may not actually be finding the network, but making the connection. This can happen when the IP address that your computer has conflicts with another device already on the network.
This can happen when you haven’t connected to the network for a long time and a new device receives your old IP address. To see if this is the cause, try releasing and renewing your IP address in the command prompt.
Select the Start menu, type command, and select the Command Prompt app.
At the command line, type ipconfig /release and press Enter.
In the text after this command, you will see the IPv4 IP address go blank.
Next, in the command line, type ipconfig /renew and press Enter.
When this command is finished, you’ll see a new IP address appear in the IPv4 Address field.
Now select the Wi-Fi icon in the taskbar and see if your Wi-Fi network now shows up.
9. Temporarily Disable Antivirus
If you’ve gotten this far and still can’t see your Wi-Fi network, it is possible that your antivirus software may be blocking it.
To test if this is the case, temporarily disable antivirus protection. Most antivirus apps have an icon on the right side of the taskbar. You can usually right-click this icon and select Pause protection.
Alternatively, you can open the antivirus app and find the network protection menu. In this window, there’s usually an option to toggle network protection off.
Once you’ve disabled protection, check if your Wi-Fi network shows up.
10. Temporarily Disable Windows Firewall
If that doesn’t work, turn to Windows Firewall as a possible culprit. Temporarily turn off the Windows Firewall to test this.
Select the Start menu, type Firewall, and select Windows Defender Firewall.
In the Windows Defender Firewall app, select Turn Windows Defender Firewall on or off in the left menu.
This will open a window where you can customize protection. Select the radio button to Turn off Windows Defender Firewall under both sections.
Select OK and then restart your computer. When it starts back up, check that Windows 10 can now find your Wi-Fi network.
Windows 10 Can’t Find Your Wi-Fi Network
If you’ve gotten this far, you only have a few other options. You may need to replace your Wi-Fi network adapter, so contact a computer technician to do this for you if you don’t know how to do it yourself.
However, before you take this step, take your computer to a local Wi-Fi hotspot and check if your network adapter can see another Wi-Fi network. If it can’t, then it’s far more likely the network adapter is the issue and you should replace it.
