您知道您家中Wi-Fi 信号强度(Wi-Fi signal strength)最大的确切位置吗？好吧，您可能可以通过任务栏中Wi-Fi图标中实心条的数量来判断这一点。但这可能不是您的最佳方式。实心条为您提供有关信号强度如何的抽象概念，但不会为您提供确切的数字或值。确切的值可以帮助您进行分析，还可以为您提供可用于改善家庭或办公室Wi-Fi信号强度的结果。
很多时候，即使互联网速度非常好，消费者也会抱怨速度问题。虽然他们可以连接，但他们无法获得基于其ISP提供的互联网速度的应有速度。问题可能是因为墙壁厚、信号低等。在这篇文章中，我们将分享可以帮助您测量 Wi-Fi 信号强度的(measure Wi-Fi signal strength)应用程序。
检查Wi-Fi 信号强度的正确方法(Wi-Fi Signal Strength)
虽然很容易查看 Wi-Fi 图标上的条数并了解信号是弱还是强，但这并不是衡量强度的准确方法，而是唯一的近似值。一些高级应用程序以 dBm 或毫瓦为单位测量 Wi-Fi 强度。
这是一个负测量，范围从 -30 到 -90，表示信号强度的损失。因此，如果您获得 -30 的信号强度，那是您能获得的最佳信号强度，而 -90 则很糟糕。也就是说，如果您想知道流媒体的理想强度或带宽重的任何东西，那么它大约是 -65 dBm。
测量 Wi-Fi 信号强度
您可以使用这些免费工具中的任何一个来测量Wi-Fi信号强度，但请务必先了解所有功能、限制和易用性。
- 芬
- Wi-Fi 分析仪
- NirSoft 的 WifiInfoView
- NetSh 命令
- 维斯布勒
- 无线连接信息。
除了 dBm，RSSI也是另一个衡量强度的单位，但它不是标准的方法。如果任何软件提供RSSI值，我们已经给出了转换公式。
1] 芬
它是您现在可以找到的测量信号(Signal)强度的最佳工具，如果您遇到 Wi-Fi 问题，还可以生成完整报告。安装工具后，切换到工具部分，然后启动 Wi-Fi 扫描以排除故障并找出您周围每个 Wi-Fi 设备的强度！
使用此工具的唯一限制是您可以每天尝试五次，但由于它会实时扫描信号强度，因此绰绰有余。此外，该应用程序也可以在智能手机上免费使用，如果您想找出特定位置的信号强度。下载(Download)飞。
2] Wi-Fi分析仪
这是一个免费工具，您可以从Microsoft Store下载。PC/laptop、平板电脑或移动设备变成您的无线网络分析仪，它可以帮助您识别 Wi-Fi 问题、(identify Wi-Fi problems,)找到最佳信道或路由器/接入点的最佳位置。使用此工具的最佳部分是它无需单击任何其他内容即可达到目的。启动该工具，它会请求许可，然后为您提供结果。
它还可以分析并帮助您找出网络问题，但这属于他们的高端细分市场。由于我们所需要的只是信号强度，而您可以检查的次数没有任何限制，因此效果很好。你可以从微软商店下载(download)
3] NirSoft 的 WifiInfoView
WifiInfoView在后台使用NetSh命令，然后将其转换为任何人都可以理解的数据。除此之外，它还可以扫描附近的其他路由器，并帮助您确定离您最近的路由器是否提供了合适的强度。它不使用 dBm，而是使用RSSI来测量信号强度。RSSI代表 r接收信号强度指示器(Received Signal Strength Indicator)。RSSI转换为DBM的公式如下
RSSI - 95 = signal strength in dBm
所以在我的场景中，根据这个工具，RSSI是 -42，等于 -53dBm，这已经足够接近了。(RSSI)
4] NetSh 命令
最简单的方法是在CMD(CMD)窗口中输入一些命令。此方法无需安装任何软件，简单快捷。确保您已连接到要在其上运行信号测试的Wi-Fi 。
Windows 提供了一个可以显示信号强度的内置命令。当您运行NETSH命令时，它将以百分比形式显示信号强度。这是命令的样子。
netsh wlan show interface
这将为您提供有关无线网络的详细信息。此类信息在网络和共享中心甚至设置应用程序中都不可用。您可以查看GUID、物理地址(Physical Address)、状态(State)、SSID、BSSID、网络类型(Network Type)、无线电类型(Radio Type)、身份验证(Authentication)、密码(Cipher)、通道(Channel)、Receive/Transmit率，最重要的是信号。信号以百分比值表示，是最准确的强度度量。您可以多次运行此命令，每次在设备周围移动一点时，您都会注意到信号值的变化。
正如您在图像中看到的那样，98% 看起来很有希望，但是如果您将其转换为 dBm，它将讲述一个不同的故事。这是将信号百分比转换为 dBm 的公式。
dBm = (quality / 2) – 100
因此 98% 的信号强度（质量）将转换为 98/2-100 = -51。这与评估-50dBm的(-50dBm)Fling工具报告相匹配。
5]维斯布勒
它是一款免费软件，可以扫描你周围的所有AP，然后显示信号强度、信道、mac地址等详细信息。它类似于 Nirsoft 的软件，但有一点不同。您还可以使用GPS作为帮助您生成地图的因素之一。但是，将它用于列表上显示的内容之外的任何内容意味着您将不得不付出一些努力。因此，除非您对技术感兴趣，否则请跳过它或仅将其用于您需要的东西。
(Download)从Vistumbler下载，让我们知道您的想法。
6]无线连接信息
如果您不喜欢这些黑盒终端窗口，那么有一个基于GUI的解决方案适合您。WirelessConnectionInfo是一个免费软件应用程序，可让您查看有关您所连接的无线网络的所有详细信息。好吧(Well)，它为您提供了命令行方法为您提供的更多详细信息，其中之一就是信号强度。您还可以将数据导出为HTML报告，然后将其用于共享目的。

如何提高Wi-Fi 信号强度(Wi-Fi Signal Strength)
这涵盖了，如果你想知道如何提高力量，(improve the strength,)那么这是一个很大的话题，但这里有一些基本规则需要遵循。
- 连接(Connect)到 5 GHz接入点，因为它提供最佳强度。
- 如果您的路由器不支持 5 GHz模式，最好换一个新的。大多数现代路由器都支持它。
- 如果您无法靠近主路由器并且有太多盲点，您可能需要升级到网状路由器，例如AmpliFi Mesh 路由器。( AmpliFi Mesh routers.)
没有灵丹妙药来获得最佳力量，但这些应该会有所帮助。以太网(Ethernet)始终服务于为您提供最佳速度的目的，但可能无法一直拥有它。我希望帖子中的软件能够帮助您确定 Wi-Fi 信号强度。
因此，您可以通过这种方式查看 Wi-Fi 连接的确切信号强度。您可以使用上述方法在您的家中或办公室中找到最佳位置。或者这些方法可用于找出安装新 Wi-Fi 路由器的最佳位置。你可以让你的电脑保持静止并移动路由器，看看信号是如何变化的。您想如何使用这些方法进行救援有无限的可能性。

How to measure WiFi signal strength in Windows 10
Do you know the еxact spot which has the maximum Wi-Fi signal strength in your house? Well, you can probably tell that by the number of solid bars in the Wi-Fi icon in the taskbar. But that might not be the best way for you. The solid bars give you an abstract idea about how the signal strength but will not give you an exact number or value. The exact value can help you in your analysis and will also provide you results that can be used to improve Wi-Fi signal strength at your home or office.
Many a time even with excellent internet speed, consumers complain of speed issues. While they can connect, they don’t get the rate they should be getting based on their internet speed offered by their ISP. The problem can be because of thick walls, low signal, and others. In this post, we will share applications that can help you measure Wi-Fi signal strength.
The right way to check Wi-Fi Signal Strength
While it is easy to look at the number of bars on the Wi-Fi icon and understand if the signal is weak or strong, but that is not an accurate way to measure strength but an only approximation. Some of the advanced applications measure Wi-Fi strength in terms of dBm or milliwatt.
It is a negative measurement which spans from -30 to -90 and signifies the loss of signal strength. So if you get a signal strength of -30, it is the best you can get while -90 is terrible. That said, if you are wondering what would be the ideal strength for streaming or anything heavy on bandwidth, then its around -65 dBm.
Measure Wi-Fi signal strength
You can use any of these free tools to measure Wi-Fi signal strength, but make sure to first go through all the features, limitations, and ease of use.
- Fing
- Wi-Fi Analyzer
- NirSoft’s WifiInfoView
- NetSh Command
- Vistumbler
- WirelessConnectionInfo.
Apart from dBm, RSSI is also another unit to measure the strength, but it’s not a standard way to do it. We have given the conversion formula if any of the software offers RSSI values.
1] Fing
It is the best tool you can find right now to measure Signal strength, and also generate a full report if you have a Wi-Fi issue. Once you install the tool, switch to the tools section, and then start the Wi-Fi scan to troubleshoot and find the strength of every Wi-Fi device around you!
The only limitation using this tool is that you can try it five times a day, but since it keeps scanning the signal strength live, it is more than enough. Also, the application is free to use on Smartphones as well, and if you are trying to find out the signal strength at a particular place. Download Fing.
2] Wi-Fi Analyzer
It’s a free tool that you can download from Microsoft Store. It can help you identify Wi-Fi problems, find the best channel, or the best place for your router/access-point by turning your PC/laptop, tablet, or mobile device into an analyzer for your wireless network. The best part of using this tool is that it serves the purpose without clicking anything else. Launch the tool, and it will ask for permission, and then get you the result.
It can also analyze and help you figure out issues with your network, but that comes under their premium segment. Since all we need is signal strength without any limit on how many times you can check, this works well. You can download from Microsoft Store
3] NirSoft’s WifiInfoView
WifiInfoView uses the NetSh command in the background and then converts it into data that anybody can understand. Apart from it can also scan for other routers in the neighborhood and help you figure out if your router being closest to you is offering the right strength. Instead of using dBm, it uses RSSI to measure signal strength. RSSI stands for r Received Signal Strength Indicator. The formula to convert RSSI into DBM is as follows
RSSI - 95 = signal strength in dBm
So in my scenario, RSSI, according to this tool, is -42, which equals -53dBm, which is close enough.
4] NetSh Command
The simplest way of doing so will be by typing in some commands in a CMD window. This method does not require any software installation, it is simple and quick. Make sure you are connected to the Wi-Fi you want to run a signal test on.
Windows offers a built-in command that can show the signal strength. When you run the NETSH command, it will display the signal strength in terms of percentage. Here is the command what it looks like.
netsh wlan show interface
This will give you detailed information about the wireless network. This type of information is not available in the network and sharing center or even the settings app. You can view GUID, Physical Address, State, SSID, BSSID, Network Type, Radio Type, Authentication, Cipher, Channel, Receive/Transmit rate, and most importantly the signal. The signal is represented as a percentage value and is the most accurate measure of strength. You can run this command as many times and you will notice the change in signal values every time you move around your device a little bit.
As you can see in the image that 98% looks promising, but if you convert it into dBm, it will tell a different story. Here is the formula for converting a signal percentage into dBm.
dBm = (quality / 2) – 100
So the 98% signal strength (quality) will convert into 98/2-100 = -51. This matches the Fling tool report, which evaluated -50dBm.
5] Vistumbler
It’s free software that can scan for all AP around you, and then display the signal strength, channel, mac address, and other details. It is similar to Nirsoft’s software, but it comes with a twist. You can also use GPS as one of the factors which help you generate a map. However, using it for anything apart from what displays on the list means you will have to put in a bit of effort. So unless you are into technical stuff, skip it or use it for only what you need.
Download from Vistumbler and let us know what you think of it.
6] WirelessConnectionInfo
If you are not fond of these black box terminal windows, then there is a GUI based solution for you. WirelessConnectionInfo is a freeware application that lets you view all the details about the wireless network you are connected to. Well, it gives you a lot more details that the command line method gave you and one of them is the signal strength. You can also export the data as an HTML report and later use it for sharing purposes.
WirelessConnectionInfo like any other Nirsoft tool offers a variety of visual customizations. It supports most of the common keyboard shortcuts and you can easily refresh the stats and signal strength by pressing F5 on your keyboard.

How to improve Wi-Fi Signal Strength
That covered, if you are wondering how you can improve the strength, then it’s a vast topic, but here are some basic rules to follow.
- Connect to a 5 GHz access point as it offers the best strength.
- If your router doesn’t support 5 GHz mode, it is best to get a new one. Most of the modern routers support it.
- If you cannot get close to your primary router and have too many blind spots, you may want to upgrade to a mesh router such as AmpliFi Mesh routers.
There is no silver bullet to get the best strength, but these should help. Ethernet always serves the purpose of getting you the best speed, but then it may not be possible to have it all the time. I hope the software in the post was able to help you figure out the Wi-Fi signal strength.
So this was how you can view the exact signal strength of a Wi-Fi connection. You can use the above methods to find the best spot in your home or office. Or these methods can be used to find out the best place to install a new Wi-Fi router. You can keep your computer static and move the router around and see how the signal changes. There are endless possibilities for how you want to use these methods for your rescue.
TIP: Homedale for Windows 10 lets you manage your WiFi strength.
