您刚刚在网上冲浪时大吃一惊，突然弹出一条小错误消息：“没有互联网(Internet)，安全”。这是一条奇怪而神秘的信息，但非常清楚的是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？它实际上比你想象的要简单得多。
“没有互联网(Internet)，安全”甚至意味着(Mean)什么？
如果您对 Internet 连接的工作方式不太了解，这可能是一条相当令人困惑的信息。但是，当您考虑它时，它实际上是完全有道理的。
你看，你的电脑没有直接连接到互联网。相反，您有一个设备，例如网络路由器，可将信息传递到您家外的广域网(Wide Area Network)( WAN )。但是，您的计算机也与路由器在您家中服务的所有其他设备联网。这被称为局域网(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。
因此，“无互联网(No Internet)，安全”状态消息仅表示您与路由器的WiFi连接良好且已正确加密（“安全”），但您的家庭路由器与外界没有互联网连接（“无互联网(No Internet)”） . 为了解决这个问题，我们需要确定互联网连接究竟为什么会死掉。
1. 可能是停电
您可能会看到此错误的最常见原因是您的ISP的 Internet 连接已断开。这不是你的错，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 10 PC 访问，那么您知道问题一定出在您的计算机上，而不是互联网连接。
2. 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ISP重置连接。您如何(How)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。无论请求哪个频道，如果您的互联网连接实际上已死，这是一个很好的第一步。
3. 您是否连接到正确的网络(Right Network)？
这可能是一个愚蠢的细节，但在开始四处寻找修复之前，请确保您已连接到正确的WiFi网络。(WiFi)您可能不小心连接到没有互联网连接的WiFi网络。(WiFi)也许你有一个你留在上面的GoPro或一个没有SIM卡的移动热点。
4.重置您的路由器(Router)（和您的计算机(Your Computer)）
在触摸您的 Windows 10 计算机之前，请先拔下路由器的电源，将其关闭几分钟，然后重新连接。根据我们的经验，这个简单的技巧可以解决大多数“没有互联网(Internet)，安全”的错误。
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，这也有机会在不进一步努力的情况下解决问题。
5. 从 WiFi 切换到以太网
由于此错误是特定于WiFi的，因此可能是您的实际WiFi硬件或软件存在问题。尝试通过以太网将(Ethernet)Windows 10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WiFi硬件、网络驱动程序或计算机或路由器本身的WiFi配置方式上。(WiFi)
6.运行网络疑难解答
如果您的 Windows 10 计算机本身存在配置错误问题，一种快速解决问题的方法是使用 Windows 自己的网络故障排除程序。这是最快的方法：
- 打开开始菜单
- 在搜索栏中，输入Find and fix network questions(and fix network problems)。
- 一旦出现，选择它。
- 选择下一步(Next)运行疑难解答。
一旦疑难解答程序完成运行，它将报告回来。如果可能的话，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。在这种情况下，您应该使用该信息来进一步告知您的故障排除工作。
7. 释放和更新 IP(Renew IP)并刷新你的 DNS(Flush Your DNS)
此错误通常是由 IP 地址问题引起的，解决此错误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——一个(— one)希望没有任何冲突的地址。为了更好地衡量，您还应该刷新DNS缓存。所有这些都是通过Windows 10命令提示符使用(Command Prompt)IPconfig实用程序来实现的。
要获取详细说明，请阅读如何释放和更新 IP 地址(How to Release and Renew an IP Address)。您将从Windows 命令提示符(Windows Command Prompt)以及您能想到的几乎所有其他设备中学习如何操作！
如果您在尝试释放和更新 IP 地址时遇到该错误，请查看 Windows 中的“如何修复无法更新 IP 地址” 。(How to Fix Cannot renew IP address” in Windows)
最后，要刷新DNS缓存，请执行以下操作：
- 右键单击开始按钮(Start Button)并选择Windows Powershell (Admin)。
- 键入ipconfig /flushdns并按Enter。
您的计算机的DNS缓存现在将被清除。希望任何与 IP 相关的问题也将得到解决。
8.回滚(Roll Back)上次的Windows 更新(Windows Update)
我们已经看到一些情况，其中这个特定问题似乎是由损坏的Windows更新引起的。无法说这是否只是与更新相关的间歇性问题。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：
- 打开开始菜单(Start Menu)，然后选择齿轮图标(gear icon)以打开Windows 设置(Windows Settings)。
- 接下来，选择更新和安全(Update & Security)。
- 选择恢复选项卡(Recovery tab)。
- 查找Go back to the previous version of Windows 10。
- 选择开始(Get Started)。
- 现在按照向导完成回滚过程。
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(Just)记住，Windows 不会无限期地保留更新恢复数据。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。话虽如此，如果更新不是最近的，它可能与您的问题无关。
9. 回滚网络驱动程序
Windows可能会不时更新您的网络驱动程序，这在极少数情况下可能会导致问题。您可以将您的WiFi或以太网(Ethernet)卡的驱动程序回滚到以前可以正常工作的版本。有关说明，请参阅如何在 Windows 10 中回滚驱动程序(How To Roll Back A Driver In Windows 10)。

How To Fix a “No Internet Secured” Error in Windows 10
You’re just having a blast surfing the іnternet, when suddenlу a small error mesѕаge pops up: “No Internet, Secured”. It’s a weird and cryptic message, but what’s perfectly clear іs that уour internet connection hаѕ stopped working.
Web pages won’t open and you can’t download a thing! What’s going on? It’s actually much simpler than you might think.
What Does “No Internet, Secured” Even Mean?
If you don’t know much about how your internet connection works, this can be a rather confusing message. However, it actually 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) outside your home. However, your computer is also networked to all the other devices the router serves inside your home. This is known as the Local Area Network (LAN) and this network will keep working even if something goes wrong with your internet connection.
So the “No Internet, Secured” status message simply means that your WiFi connection to the router is fine and properly encrypted (“Secured”), but that there’s no internet connection from your home router to the outside world (“No Internet”). To solve this issue, we need to determine why exactly the internet connection is dead.
1. It Could Be an Outage
The most common reason you may see this error is because your internet connection from the ISP is down. This isn’t 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 some other device like your smartphone but not your Windows 10 PC then you know the problem must be with your computer and not the internet connection.
2. Reset Your ISP Connection
If you’re using fiber or DSL, you can sometimes request a connection reset by the ISP. How you do this depends on the ISP. You might have an app, a support email address or a phone number. Whichever the channel to request one, this is a good first step if your internet connection is actually dead.
3. Are You Connected to the Right Network?
It’s a silly detail perhaps, but make sure you’re connected to the right WiFi network before you start poking around for a fix. You may have accidentally connected to a WiFi 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 in it.
4. Reset Your Router (and Your Computer)
Before touching your Windows 10 computer, start by unplugging your router’s power, leaving it off for a few minutes and then reconnecting. In our experience this simple trick resolves most “No Internet, Secured” errors.
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.
5. Switch From WiFi to Ethernet
Since this error is WiFi specific, it might be a problem with your actual WiFi hardware or software. Try connecting the Windows 10 computer to the router via Ethernet instead. If the internet connection starts working, it’s a sign that the problem is either with the WiFi hardware, network drivers, or how WiFi has been configured on the computer or the router itself.
6. Run the Network Troubleshooter
If there’s a misconfiguration problem on your Windows 10 computer itself, one quick way to get to the bottom of it is by using Windows’ own network troubleshooter. Here’s the quickest way to do it:
- Open the Start Menu
- In the search bar, type Find and fix network problems.
- Once it appears, select it.
- Select Next to run the troubleshooter.
Once the troubleshooter has finished running, it will report back. If at all 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. In which case you should use that information to further inform your troubleshooting efforts.
7. Release and Renew IP and Flush Your DNS
This error is often caused by IP address problems 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 — one which hopefully doesn’t have any conflicts. For good measure, you should also flush the DNS cache. All of this is achieved by using the IPconfig utility through the Windows 10 Command Prompt.
To get detailed instructions, read How to Release and Renew an IP Address. You’ll learn how to do it from the Windows Command Prompt and just about every other device you can think of as well!
Have a look at How to Fix Cannot renew IP address” in Windows if you get that error when trying to release and renew your IP address.
Finally, to flush your DNS cache do this:
- Right-click on the Start Button and select Windows Powershell (Admin).
- Type ipconfig /flushdns and press Enter.
Your computer’s DNS cache will now be cleared out. Hopefully any IP-related problems will have been cleared out as well.
8. Roll Back the Last Windows Update
We’ve seen some cases where this particular issue seems to be caused by a broken Windows update. It’s impossible to say whether this is just a case of intermittent problems being associated with 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:
- Open the Start Menu and then select the gear icon to open Windows Settings.
- Next, select Update & Security.
- Select the Recovery tab.
- Look for Go back to the previous version of Windows 10.
- Select Get Started.
- Now follow the wizard to complete the roll-back process.
If your last Windows update was somehow related to the error, it should all work again. Just keep in mind that Windows does not keep the update 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 being said, if the update wasn’t recent it probably isn’t related to your problem anyway.
9. Rolling Back Network Drivers
From time to time, Windows might update your network drivers, which can cause issues on rare occasions. You can roll your WiFi or Ethernet card’s driver back to the previous version that worked properly quite easily. Refer to How To Roll Back A Driver In Windows 10 for the instructions.
