当突然弹出“无互联网^{(No Internet)}，安全”错误消息时，您正在网上冲浪。这是一条奇怪而神秘的信息，但很明显，您的互联网连接已停止工作。

网页^(Web)打不开，你也不能下载东西！这是怎么回事？在Windows 10^{(Windows 10)}或 11 PC 上解决问题比您想象的要简单得多。

“没有互联网^(Internet)，安全”甚至意味着^(Mean)什么？

如果您不太了解 Internet 连接的工作原理，则此错误消息可能会有些混乱。但是，当您考虑它时，它是完全有道理的。

你看，你的电脑没有直接连接到互联网。相反，您有一个设备，例如将信息传递到广域网^{(Wide Area Network)}( WAN ) 的网络路由器。但是，您的计算机也与路由器在您家中提供服务的其他设备联网。这就是所谓的局域网 (LAN)^{(Local Area Network (LAN))}，即使您的互联网连接出现问题，该网络也将继续工作。

“无互联网，安全”状态消息仅表示虽然您与Wi-Fi路由器的连接良好且已充分加密（“安全”），但您没有收到任何数据。我们需要确定互联网连接失效的原因才能解决此问题。

检查网络中断

您可能会看到此错误的最常见原因是您的 ISP 的互联网连接已关闭。那不是你的错，这意味着你没有错。检查这一点的最简单方法是查看您是否通过同一路由器上的不同设备连接互联网。

如果您可以通过智能手机等其他设备访问网络，但不能通过 Windows PC 访问网络，那么您就知道问题一定出在您的计算机上，而不是互联网连接上。

重置您的 ISP 连接

如果您使用的是光纤或DSL，您有时可以请求Internet 服务提供商^{(Internet Service Provider)}( ISP ) 重置连接。您如何执行此操作取决于ISP。您可能有一个应用程序、一个支持电子邮件地址或一个电话号码。无论您使用哪种渠道，联系您的ISP都是解决互联网连接中断问题的良好第一步。

验证您的连接状态

如果您的计算机以外的其他设备可以访问互联网，请确认您的计算机已连接到正确的网络。这是一个愚蠢的细节，但在四处寻找修复之前， 请确保您已连接到正确的Wi-Fi网络。^(Wi-Fi)

您可能不小心连接到没有互联网连接的 Wi-Fi 网络。也许您有一个没有使用的GoPro，或者一个没有SIM卡的移动热点。

禁用您的 VPN 连接或应用程序

虚拟专用网络 (VPN)^{(Virtual Private Networks (VPNs))}可以帮助您更安全、更私密地上网。但是，它们有时会中断您设备的互联网连接。如果您的 PC 上有一个活动的VPN应用程序，请将其关闭并检查是否停止“无互联网^{(No Internet)}，安全”错误。

如果VPN^(VPNs)有故障或过时，它们也可能出现故障。因此，我们建议您更新您的VPN应用程序并使其保持最新状态。

重置您的路由器^(Router)（和您的计算机^{(Your Computer)}）

在接触您的Windows计算机之前，请拔下路由器的电源并保持几分钟。之后^(Afterward)，将 Wi-Fi 路由器重新连接到墙上插座并重新打开电源。这个简单的技巧可以清除Windows系统托盘或通知区域中的“No Internet, Secured”连接错误。

当您使用它时，请同时重新启动您的计算机。它不会受到伤害，而且这也有机会在不进一步努力的情况下解决问题。

重置计算机的网络设置^{(Network Settings)}

将 PC 的 Internet 设置恢复为出厂默认设置是解决“无 Internet，安全”错误和其他网络相关问题的另一种方法。

如果您的 PC 运行Windows 11，请转到Settings > Network和Internet > Advanced网络设置> Network重置，然后选择立即重置^(Reset)。

在Windows 10中，前往Settings > Network和Internet >Status > Network重置，然后选择立即重置^(Reset)。

Windows 将在网络重置操作后重新启动您的计算机。将您的 PC 重新连接到Wi-Fi网络并检查您是否可以访问互联网。

从 Wi-Fi 切换到以太网

由于此错误特定于 Wi-Fi 连接，因此可能是您的实际 Wi-Fi 硬件或软件存在问题。尝试通过以太网将^(Ethernet)Windows 10或 11 计算机连接到路由器。如果互联网连接开始工作，则表明问题出在Wi-Fi硬件、网络驱动程序或计算机或路由器本身 的Wi-Fi配置方式上。^(Wi-Fi)

运行Windows 网络疑难解答^{(Windows Network Troubleshooter)}

如果您的Windows计算机上存在配置错误问题，一种快速查明问题的方法是使用Windows的网络疑难解答。

在Windows 11中，前往Settings > System > Troubleshoot >其他疑难解答”，然后选择“ Internet 连接^{(Internet Connections)}”旁边的“运行^(Run)” 。

如果您的 PC 运行Windows 10，请转到Settings > Network和Internet >Status > Change网络设置，然后选择网络^(Network)疑难解答。您还可以通过控制面板^{(Control Panel)}运行网络疑难解答。

1. 打开开始菜单
2. 在搜索栏中键入并选择查找^(Find)和修复网络问题，然后选择打开^(Open)。

1. 选择下一步^{(Select Next)}运行疑难解答。

故障排除程序将在诊断您的 PC 后显示报告。如果可能，它会告诉您问题已找到并已修复。希望^(Hopefully)这将解决您的互联网连接问题。或者，它可能会告诉您出了什么问题，但无法修复它。您应该使用该信息来进一步告知您的故障排除工作。

更改网络设置

尽管Microsoft不建议禁用Internet 协议版本 6 (IPv6)^{(Internet Protocol version 6 (IPv6))}，但这样做可以暂时修复Windows 10和 11 中的连接问题。

1. 按Windows键 + X 并选择Network Connections。

1. ^{(Select Advanced)}选择页面底部的 高级网络设置。

1. 滚动到“相关设置”部分并选择更多网络适配器选项（或在Windows 10中^{(Windows 10)}更改^(Change)适配器选项）。

1. 双击显示“^{(Double-click)}无互联网^{(No Internet)}，安全”错误消息 的无线网络。

1. 选择属性以打开无线适配器设置。

1. ^{(Uncheck Internet Protocol Version 6)}在连接属性窗口中取消选中 Internet 协议版本 6 ( TCP/IPv6选中“ Internet 协议版本 4^{(Internet Protocol Version 4)} ( TCP/IPv4 )”框，然后选择“确定”继续。

如果在禁用IPv6^(IPv6)时错误仍然存​​在或其他 Windows 组件出现故障，请重新启用IPv6协议。

刷新 PC 的IP 配置^{(IP Configuration)}并刷新 DNS 缓存^{(Flush DNS Cache)}

IP 地址问题通常会导致此错误，解决此问题的快速方法是让有问题的计算机释放路由器分配给它的 IP 地址。然后您的计算机将简单地向路由器询问一个新的 IP 地址，希望不会有任何冲突。

有关详细说明，请参阅我们关于在 Windows 中更新或刷新 IP 地址^{(renewing or refreshing IP addresses in Windows)}的教程。

您还应该通过Windows命令提示符^{(Command Prompt)}或PowerShell使用^(PowerShell)IPconfig实用程序刷新 PC 的DNS缓存。要刷新DNS缓存，请执行以下操作：

1. 按^(Press)PC 的Windows键，在搜索栏中键入 powershell，然后选择Run as Administrator。

1. 在终端中键入或粘贴 ipconfig /flushdns 并按Enter。

当您看到“成功刷新 DNS 解析器缓存”成功消息时关闭Windows Powershell 。这应该可以解决任何与 IP 相关的问题并恢复对Wi-Fi网络的互联网访问。

更新您的计算机

Windows中与网络相关的错误出现在旧版本的操作系统中。如果您很久没有更新您的计算机，请安装适用于您的计算机的最新Windows版本。

转到Settings > Windows Update（或Windows 10中的^{(Windows 10)}更新^(Updates)和安全），然后选择检查^(Check)更新或全部安装^(Install)。

回滚上次的 Windows 更新

有趣的是，损坏的Windows更新也可能导致此错误。不可能说这是否只是错误更新的情况。尽管如此，回滚最新的Windows更新以查看它是否有任何影响并修复错误并没有什么坏处。

要撤消上次Windows更新，请执行以下操作：

1. 按Windows键 + I 打开Windows 设置^{(Windows Settings)}菜单。
2. 选择侧栏上的Windows 更新，然后选择^{(Windows Update)}更新^(Update)历史记录。

1. 滚动到“相关设置”部分，然后选择卸载^(Uninstall)更新。

1. 找到您怀疑导致“无互联网，安全”错误的（最新）更新。选择卸载^{(Select Uninstall)}以删除更新并将您的 PC 回滚到以前的Windows版本。

在Windows 10中，转到Settings > Update和Security > Recovery > Go返回到以前的Windows 10版本，然后选择“开始^{(Get Started)}使用” 。

如果您上次的Windows更新与该错误有某种关联，那么它应该会再次正常工作。请记住，Windows不会无限期地保留更新的恢复数据。因此，如果自上次更新以来已经很长时间，您可能无法回滚更新。也就是说，如果更新不是最近的，它可能与您的问题无关。

回滚网络驱动程序

Windows 可能会偶尔更新您的网络驱动程序，这有时会导致问题。您可以将Wi-Fi或以太网^(Ethernet)卡的驱动程序回滚到正常工作的稳定版本。请参阅我们关于在 Windows 中回滚驱动程序^{(rolling back drivers in Windows)}的教程以获取分步说明。

更新或重新安装网络适配器驱动程序^{(Reinstall Network Adapter Driver)}

如果您的计算机的网络适配器漏洞百出或已过时，您的计算机可能无法连接到 Internet。更新计算机的网络适配器可能会解决“无 Internet 安全”错误。

1. 按^(Press)Windows键 + R 打开Windows运行^{(Windows Run)}框。
2. 在“运行”^(Run)框中键入或粘贴 devmgmt.msc，然后选择“确定”或按Enter。这将启动Windows 设备管理器^{(Windows Device Manager)}。

或者，右键单击 PC 任务栏上的Windows图标，然后在弹出菜单中 选择设备管理器。^{(Device Manager)}

1. 展开^(Expand)网络^(Network)适配器类别，右键单击您的网络适配器，然后选择更新驱动^(Update)程序。

1. 如果问题仍然存在，请删除 PC 的网络驱动程序并重新安装驱动程序的新副本。右键单击^{(Right-click)}适配器并选择卸载^(Uninstall)设备。

1. ^{(Select Uninstall)}在确认页面上 选择卸载。

How to Fix a “No Internet Secured” Error in Windows 10 & 11

Υou’re having a blast surfing thе internet when a “No Internet, Secured” error message suddenly pops up. It’s a weird and crуptic message, but what’s clear is that your internet connection has stopped working.

Web pages won’t open, and you can’t download a thing! What’s going on? It’s much simpler than you think to fix the issue on a Windows 10 or 11 PC.

What Does “No Internet, Secured” Even Mean?

This error message can be somewhat confusing if you don’t know much about how your internet connection works. However, it makes perfect sense when you think about it.

You see, your computer isn’t directly connected to the internet. Instead, you have a device such as a network router passing information to the Wide Area Network (WAN). However, your computer is also networked to other devices the router serves inside your home. That’s known as the Local Area Network (LAN), and this network will keep working even if something goes wrong with your internet connection.

The “No Internet, Secured” status message simply means that while your connection to the Wi-Fi router is fine and adequately encrypted (“Secured”), you aren’t receiving any data. We need to determine why the internet connection is dead to solve this issue.

Check for Network Outage

The most common reason you may see this error is that your ISP’s internet connection is down. That’s not your fault, and it means there’s nothing wrong on your end. The easiest way to check for this is to see whether you have an internet connection through a different device on the same router.

If you can access the web through another device like your smartphone but not your Windows PC, you know the problem must be with your computer, not the internet connection.

Reset Your ISP Connection

If you’re using fiber or DSL, you can sometimes request a connection reset by the Internet Service Provider (ISP). How you do this depends on the ISP. You might have an app, a support email address, or a phone number. Whatever channel you use, contacting your ISP is a good first step to resolving problems with internet connectivity outages.

Verify Your Connection Status

If other devices but your computer can access the internet, verify that your computer is connected to the correct network. It’s a silly detail, but make sure you’re connected to the right Wi-Fi network before poking around for a fix.

You may have accidentally connected to a Wi-Fi network that doesn’t have an internet connection. Perhaps you have a GoPro that you left on or a mobile hotspot that doesn’t have a SIM card.

Disable Your VPN Connection or App

Virtual Private Networks (VPNs) can help you surf the internet more securely and privately. However, they can occasionally disrupt your device’s internet connection. If you have an active VPN app on your PC, turn it off and check if that stops the “No Internet, secured” error.

VPNs can also malfunction if they’re buggy or outdated. Therefore, we recommend updating your VPN app and keeping it up-to-date.

Reset Your Router (and Your Computer)

Before touching your Windows computer, unplug your router’s power and leave it unplugged for a few minutes. Afterward, reconnect the Wi-Fi router to the wall outlet and power it back on. This simple trick can clear the “No Internet, Secured” connection error in the Windows system tray or notification area.

While you’re at it, reboot your computer as well. It can’t hurt, and this also has a chance of resolving the issue without further effort.

Reset Your Computer’s Network Settings

Restoring your PC’s internet settings to factory default is another way to resolve the “No Internet, secured” error and other network-related issues.

If your PC runs Windows 11, go to Settings > Network & Internet > Advanced network settings > Network reset and select Reset now.

In Windows 10, head to Settings > Network & Internet > Status > Network reset and select Reset now.

Windows will reboot your computer after the network reset operation. Reconnect your PC to the Wi-Fi network and check if you can access the internet.

Switch From Wi-Fi to Ethernet

Since this error is specific to Wi-Fi connections, it might be a problem with your actual Wi-Fi hardware or software. Try connecting the Windows 10 or 11 computer to the router via Ethernet instead. If the internet connection starts working, it’s a sign that the problem is either with the Wi-Fi hardware, network drivers, or how the Wi-Fi has been configured on the computer or the router itself.

Run the Windows Network Troubleshooter

If there’s a misconfiguration problem on your Windows computer, one quick way to get to the bottom of it is by using Windows’ network troubleshooter.

In Windows 11, head to Settings > System > Troubleshoot > Other troubleshooters and select Run next to “Internet Connections.”

If your PC runs Windows 10, go to Settings > Network & Internet > Status > Change your network settings and select Network troubleshooter. You can also run the network troubleshooter through the Control Panel.

1. Open the Start Menu
2. Type and select Find and fix network problems in the search bar, and select Open.

1. Select Next to run the troubleshooter.

The troubleshooter will show a report once it diagnoses your PC. If possible, it will tell you that problems were found and repaired. Hopefully, that will solve your internet connection issue. Alternatively, it may tell you what’s wrong but won’t be able to fix it. You should use that information to inform your troubleshooting efforts further.

Change Networking Settings

Although Microsoft doesn’t recommend disabling the Internet Protocol version 6 (IPv6), doing so could temporarily fix connection problems in Windows 10 and 11.

1. Press Windows key + X and select Network Connections.

1. Select Advanced network settings at the bottom of the page.

1. Scroll to the “Related settings” section and select More network adapter options (or Change adapter options in Windows 10).

1. Double-click the wireless network displaying the “No Internet, secured” error message.

1. Select Properties to open the wireless adapter settings.

1. Uncheck Internet Protocol Version 6 (TCP/IPv6) in the connection properties window. Leave the “Internet Protocol Version 4 (TCP/IPv4)” box checked and select OK to proceed.

Re-enable the IPv6 protocol if the error persists or other Windows components malfunction when you disable IPv6.

Refresh Your PC’s IP Configuration and Flush DNS Cache

IP address problems often cause this error, and a fast way to resolve it is to get the computer in question to release the IP address the router has assigned to it. Then your computer will simply ask the router for a new IP address, which hopefully doesn’t have any conflicts.

Refer to our tutorial on renewing or refreshing IP addresses in Windows for detailed instructions.

You should also flush your PC’s DNS cache using the IPconfig utility through the Windows Command Prompt or PowerShell. To flush your DNS cache, do this:

1. Press your PC’s Windows key, type powershell in the search bar, and select Run as Administrator.

1. Type or paste ipconfig /flushdns in the terminal and press Enter.

Close Windows Powershell when you see a “Successfully flushed the DNS Resolver Cache” success message. That should fix any IP-related problems and restore internet access to the Wi-Fi network.

Update Your Computer

Network-related errors in Windows crop up in older versions of the operating system. If you haven’t updated your computer in a long time, install the latest Windows version available for your computer.

Go to Settings > Windows Update (or Updates & security in Windows 10) and select Check for updates or Install all.

Roll Back the Last Windows Update

Interestingly, a broken Windows update can also cause this error. It’s impossible to say whether this is just a case of buggy updates. Still, there’s no harm in rolling back the most recent Windows update to see if it makes any difference and fixes the error.

To undo the last Windows update, here’s what to do:

1. Press Windows key + I to open the Windows Settings menu.
2. Select Windows Update on the sidebar and choose Update history.

1. Scroll to the “Related settings” section and select Uninstall updates.

1. Locate the (latest) update that you suspect is responsible for the “No Internet, secured” error. Select Uninstall to delete the update and roll your PC back to the previous Windows version.

In Windows 10, go to Settings > Update & Security > Recovery > Go back to the previous version of Windows 10 and select Get Started.

If your last Windows update was somehow related to the error, it should all work again. Remember that Windows does not keep the updated recovery data indefinitely. So if it’s been a long time since your last update, you may not be able to roll the update back. That said, if the update wasn’t recent, it probably isn’t related to your problem.

Rolling Back Network Drivers

Windows might update your network drivers occasionally, which can occasionally cause issues. You can roll your Wi-Fi or Ethernet card’s driver back to a stable version that worked properly. Refer to our tutorial on rolling back drivers in Windows for step-by-step instructions.

Update or Reinstall Network Adapter Driver

Your computer might fail to connect to the internet if its network adapters are bug-ridden or outdated. Updating your computer’s network adapter might resolve the “No Internet Secured” error.

1. Press the Windows key + R to open the Windows Run box.
2. Type or paste devmgmt.msc in the Run box and select OK or press Enter. That will launch the Windows Device Manager.

Alternatively, right-click the Windows icon on your PC’s taskbar and select Device Manager on the pop-up menu.

1. Expand the Network adapters category, right-click your network adapter, and select Update driver.

1. If the problem persists, delete your PC’s network driver and reinstall a fresh copy of the driver. Right-click the adapter and select Uninstall device.

1. Select Uninstall on the confirmation page.

Restart your computer when the uninstallation is complete. Windows will automatically (re)install the driver when your computer comes back on. Connect your PC to a Wi-Fi network and check if reinstalling the network driver resolved the problem.
