WiFi很棒，因为它提供了自由，虽然与WiFi相比，(WiFi)以太网(Ethernet)仍然在提供更好的速度方面占主导地位，但没有什么比坐在任何你想坐在任何地方工作或欣赏电影的地方都好。没有电线！但是当您遇到问题时，有线连接听起来更可靠。在这篇文章中，我们将展示如何在Windows 11/10WiFi问题并毫无问题地使用它。
修复 Windows 11/10 中的 WiFi 问题
从技术上讲，Wi-Fi 适配器与以太网适配器(Ethernet Adapters)不同，但在功能方面，它们都是网络适配器。因此，除非是硬件问题，否则两者的故障排除或多或少是相同的。Windows 11/10中最常见WiFi问题的提示列表：
- 打开 WiFi 适配器
- (WiFi)行动中心(Action Center)缺少WiFi
- WiFi 无法自动连接
- 连接到WiFi，但没有或有限的互联网(Internet)
- (Problem)无线适配器或接入点问题
- Windows 10 上的 Wi-Fi(Wi-Fi) 信号强度低
- WiFi一直断开连接
- 找不到 WiFi 网络
- 更新 WiFi 驱动程序
在我们继续之前，您应该确定一件事。您的 ISP没有问题(no issue with your ISP)。如果是这种情况，并且您的WiFi适配器工作正常，那么您无能为力。最好的查找方法是将互联网与另一台设备连接起来。
1]打开WiFi适配器
从基础开始总是一个好主意。就像我们要求以太网适配器一样，检查WiFi是否已打开或未禁用是必不可少的。遗憾的是，Windows连接图标没有发送明确的信息，因此您需要进行一些手动挖掘。
单击(Click)系统托盘中的WiFi图标，并确保它不是灰色或深色阴影。如果是这种情况，则适配器已关闭。如果是这种情况，那么您还应该看到一个下拉选项，上面写着Turn WiFi back on—Manually/In 1hr/4hrs/in 1day。单击(Click)WiFi图标将其打开。颜色现在应该与系统的强调色相匹配。最后，点击你要连接的网络，输入密码，完成。
早些时候，Windows使用以太网电缆未连接的明确消息替换系统托盘中的连接图标。这同样适用于WiFi。现在你看到的只是一个地球图标，上面写着“未连接 - 没有可用的连接。“
2]行动中心(Action Center)缺少WiFi
当您点击地球(Globe)图标时，没有打开WiFi的选项，那是因为WiFi 适配器(WiFi Adapter)已被禁用。
- 单击(Click)地球Globe Icon > Network和Internet Settings >更改适配器选项
- 在下一个屏幕上找到您的WiFi适配器，然后双击以启用它。
- 要检查问题，您可以右键单击并选择诊断，这将启动故障排除程序。
内部程序将解决WiFi问题，并使用标准方法修复它。

Windows 10 屏幕截图
如果你经常连接网络，但是每次打开WiFi都没有自动连接，( doesn’t connect automatically,)那是因为你需要打开那个选项。连接到新网络时，请务必选中“自动连接”框。要将选项恢复到已连接的网络，请断开连接，然后再次选择适配器。“自动连接(Connect)”选项将显示出来。
4]连接到WiFi，但没有或有限的互联网(Internet)
因此，既然您正在使用已连接到WiFi的计算机，则互联网正在其他设备上运行；让我们找出在这种情况下如何解决它。这里通常有两种情况 - 没有互联网(Internet)或受限互联网 - 对于(Internet—for)后者，请按照我们的指南修复受限 WiFi 连接问题，但对于前者，您可以执行以下操作。
疑难解答(Troubleshooter)
- 转到Settings > Windows Update和Security > Troubleshoot。
- 选择Internet Connection，然后单击“运行疑难解答”按钮。
用于解决 WiFi 问题的 Shell 命令 (Shell Commands to troubleshoot WiFi problems )
以管理员身份打开命令提示符(Command Prompt)，依次运行以下命令以刷新 DNS 缓存(flush DNS cache)、重置 TCP/IP和重置 Winsock(reset Winsock)：
netsh winsock reset
netsh int ip reset
ipconfig /flushdns
Netsh是用于管理网络连接的命令行实用程序。Winsock或Windows Socket决定任何程序(Windows Socket)如何(Winsock)处理Internet应用程序的输入/输出请求。因此(Hence)重置可能会有所帮助。
(ipconfig,)另一方面，ipconfig可以清除大量缓冲区并使用 DHCP 更新 WiFi 连接(renew the WiFi connection with the DHCP)。任何命令选项都可以帮助您实现它。
这两个命令都会在某种程度上刷新WiFi状态，并帮助您解决WiFi问题。
顺便说一句，我们的便携式免费软件FixWin允许您通过单击来重置这些以及大多数其他Windows设置或功能。
5] 无线适配器或接入点问题(Problem)
使用网络(Network)疑难解答解决WiFi问题时，如果您收到“无线适配器或接入点问题”的错误消息，(Problem with wireless adapter or access point,”)则可能是由多种原因造成的。尽管如此，大多数情况下，您仍需要重新启动调制解调器、路由器和计算机。有时设备无法保持其状态，这会导致意外问题。
这是一个经典的例子。有时，我需要从路由器中取出以太网电缆并将其插入。如果我不这样做，路由器就会不断断开连接，就好像有人关闭了电源的电源一样。
6] Windows 11/10 上的低 Wi-Fi信号强度(Low Wi-Fi)
这不是与您的WiFi适配器或Windows相关的问题。Windows WiFi图标通常会显示您连接的WiFi强度，如果强度较低，则需要靠近信号源。如果您拥有路由器，并且它在办公室或家中的位置，您应该计划通过购买功能强大的路由器或添加扩展器来扩大 WiFi 范围和覆盖范围。(widen the WiFi range)此外，您可以考虑切换到 2.4 GHz，它提供更宽的范围但强度更低。
阅读(Read)：如何提高 WiFi 速度和信号强度以及覆盖范围(increase WiFi Speed and Signal strength and coverage area)。
7] WiFi不断断开连接
与上述问题类似，如果信号强度太弱， WiFi会一直断开连接。(WiFi)如果不是这种情况，请按照我们的详细指南解决此问题。这可能是因为计算机过早进入睡眠模式，或者 VPN 正在使用Kill Switch 断开连接。
8]无法找到WiFi网络
这里有两种情况。首先(First)是您找不到特定WiFi网络的地方。其次(Second)，您无法看到大部分WiFi网络，并且有时扫描是空的。
第一种情况可能意味着您没有靠近范围或WiFi SSID 被隐藏(WiFi SSID is hidden)。许多人创建网络并对其进行保护以确保安全。在这种情况下，您需要获取有关确切SSID的信息，然后手动连接到它。
如果您属于第二类，那么如果问题在最近更新后开始出现，您可能需要更新您的WiFi驱动程序或回滚更新本身。
9]更新WiFi驱动程序
有几种方法可以做到这一点，但您可能必须尝试找出有效的方法。驱动器问题通常发生在推出功能更新时，并且OEM尚未更新或将其驱动器包含在Windows更新中。虽然Windows团队通常会在大多数情况下处理此类问题，但这是一个失误，您可以选择更新驱动程序：(update the driver:)
- OEM网站：如果您购买了品牌笔记本电脑，我强烈建议您查看他们是否推出了更新
- WiFi 适配器 OEM：找出 WiFi 适配器的实际制造商(Find out the actual manufacturer)，(WiFi)并检查他们是否已更新以适应最新版本的Windows。
我希望这些在Windows 10中解决(Windows 10)WiFi问题的技巧可以帮助您解决您遇到的问题。这是一个广泛的话题，所以如果这里没有列出一个问题，请告诉我们。
How to fix WiFi problems in Windows 11/10
WiFi is great because it gives freedom, and while Ethernet still dominates in delivering better speed compared to WiFi, there is nothing like sitting anywhere you wish and work or enjoy a movie. No wires! But then when you face issues, a wired connection sounds more reliable. In this post, we will show how you can troubleshoot WiFi problems in Windows 11/10 and use it without any problem.
Fix WiFi problems in Windows 11/10
Technically, Wi-Fi adapters are different from Ethernet Adapters, but when it comes to functionality, they are both network adapters. So unless it’s a problem with the hardware, troubleshooting both is more or less the same. Here is our list of tips to fix the most common WiFi problems in Windows 11/10:
- Turn on WiFi Adapter
- WiFi is missing from the Action Center
- WiFi doesn’t connect automatically
- Connected to WiFi, but No or Limited Internet
- Problem with wireless adapter or access point
- Low Wi-Fi signal strength on Windows 10
- WiFi keeps disconnecting
- Unable to find WiFi Networks
- Update WiFi Driver
Before we go ahead, there is one thing you should get sure of. There is no issue with your ISP. If that’s the case, and your WiFi adapter is working fine, then there is nothing much you can do. The best way to find is by connecting the internet with another device.
1] Turn on WiFi Adapter
It is always a good idea to start with the basics. Just like we asked for an Ethernet adapter, it is essential to check if WiFi is turned on or not disabled. Sadly, the Windows connectivity icon doesn’t send a clear message, and hence you need to do some manual digging.
Click on the WiFi icon in the system tray, and make sure it’s not grey or dark shaded. If that’s the case, then the adapter is turned off. If that’s the case, then you should also see a drop-down option that says Turn WiFi back on—Manually/In 1hr/4hrs/in 1day. Click on the WiFi icon to turn it on. The color should now match the accent color of the system. Lastly, click on the network you plan to connect, enter the password, to complete.
Earlier, Windows used to replace the connectivity icon in the system tray with a clear message that the ethernet cable is not connected. The same applied to WiFi. Now all you get to see is a globe icon that says “Not connected – No connections are available. “
2] WiFi is missing from the Action Center
When you click on the Globe icon, and there is no option to turn on WiFi, then it’s because the WiFi Adapter has been disabled.
- Click on the Globe Icon > Network and Internet Settings > change adapter options
- Locate your WiFi adapter on the next screen, and double click to enable it.
- To check for issues, you can right-click and choose to diagnose, which will launch the troubleshooter.
The inhouse-program will troubleshoot WiFi problems, and fix it using standard methods.

3] Computer doesn’t connect to WiFi automatically

Windows 10 screenshot
If you often connect to a network, but every time you turn on WiFi, it doesn’t connect automatically, then it’s because you need to turn on that option. When connecting to a new network, always make sure to check the box which says—connect automatically. To get the option back to the already connected network, disconnect, and then select the adapter again. The “Connect automatically” choice will reveal itself.
4] Connected to WiFi, but No or Limited Internet
So now that you are using that computer is connected to WiFi, the internet is working on other devices; let’s find out how to fix it in this situation. There are usually two situations here—No Internet or Limited Internet—for the latter, follow our guide to fixing the Limited WiFi connection problem, but for the former, here is what you can do.
Troubleshooter
- Go to Settings > Windows Update and Security > Troubleshoot.
- Select Internet Connection, and then click on the button which says, “Run the troubleshooter.”
Shell Commands to troubleshoot WiFi problems
Open Command Prompt as admin, and run the following commands one after the other to flush DNS cache, reset TCP/IP and reset Winsock:
netsh winsock reset
netsh int ip reset
ipconfig /flushdns
Netsh is a command-line utility to manage network connections. While Winsock or Windows Socket decides how any program handles input/output requests for Internet applications. Hence reset may help.
ipconfig, on the other, can clear out a lot of buffers and renew the WiFi connection with the DHCP. Any of the command options can help you achieve it.
Both of these commands will refresh WiFi status, in a way, and help you troubleshoot WiFi problems.
Incidentally, our portable freeware FixWin allows you to reset these and most other Windows settings or functions with a single click.
5] Problem with wireless adapter or access point
When troubleshooting WiFi issues using Network troubleshooters, if you receive an error saying “Problem with wireless adapter or access point,” then it can be because of multiple reasons. Still, mostly, you will need to power-cycle the modem, router, and computer. At times the devices are not able to hold their state, and that causes unexpected issues.
Here is a classic example. Once in a while, I need to take out the ethernet cable from my router and plug it in. If I don’t do that, the router keeps disconnecting as if someone has turned off the power of the source.
6] Low Wi-Fi signal strength on Windows 11/10
It is not an issue that is related to your WiFi adapter or Windows. Windows WiFi icon usually shows the strength of WiFi you are connected, and if it is low, then you need to move close to the source. If you own the router, and its place in your office or home, you should plan to widen the WiFi range and reach by either purchasing a powerful router or adding extenders to it. Additionally, you can think of switching to 2.4 GHz, which offers a broader range but lower strength.

7] WiFi keeps disconnecting
Similar to the above issue, WiFi can keep disconnecting if the signal strength is too weak. If that’s not the case, then follow our detailed guide to fix this. It can be because the computer gets into sleep mode too early, or the VPN is using the Kill Switch to disconnect.
8] Unable to find WiFi Networks
There are two scenarios here. First is where you cannot find a particular WiFi network. Second, you are not able to see most of the WiFi network, and at times, the scan is empty.
The first case can mean that either you are not close to the range or the WiFi SSID is hidden. Many people create a network and keep it protected for security. In that case, you need to get information about the exact SSID, and then manually connect to it.
If you fall into the second category, then you may need to update your WiFi driver if the issue started occurring after a recent update or roll back the update itself.
9] Update WiFi Driver
There are a couple of ways to do this, but you may have to try to figure out what works. Drive issue usually occurs when a feature update is rolled out, and OEM hasn’t updated or included their drive with the Windows update. While Windows team typically take care of such issue, most of the time, but its a slip then you can choose to update the driver:
- OEM website: If you bought a branded laptop, I would strongly suggest you find if they have rolled out an update
- WiFi adapter OEM: Find out the actual manufacturer of the WiFi adapter and check if they have updated to get along with the latest release of Windows.
I hope these tips to troubleshoot WiFi problems in Windows 10 help you fix the issue you have. It’s a broad topic, so if there is an issue that is not listed here, do let us know.
