您可能需要找到您所在地区广播的所有无线网络，包括WiFi 信号(WiFi signal)较弱的无线网络和隐藏其SSID（网络名称(network name)）的无线网络。对于此任务，您必须安装无线网络扫描仪(wireless network scanner)并使用它来识别您所在地区的WiFi网络。(WiFi)然而，这些工具中有许多都很昂贵，而且只有少数是免费的并且运行良好。在本教程中，我们向您展示了一个可在所有版本的Windows中免费使用的工具。让我们开始吧：
步骤 1(Step 1)。下载并安装NetSpot（免费隐藏 wifi 查找器(hidden wifi finder)）
第一步是从这个页面下载并安装(page)NetSpot 免费版(NetSpot FREE edition)。安装应用程序。按照设置说明进行操作，几秒钟后安装就结束了。
然后，启动Netspot。如果您只想发现您所在地区的WiFi网络并对其进行分析，您可以免费使用此应用程序。(WiFi)如果您需要高级功能，如高级可视化分析和无线网络规划(analysis and planning)，则需要购买PRO 版本(PRO version)。您可以从以下评论中找到有关Netspot的更多信息，以及为什么它是一个绝佳选择：NetSpot 评论(NetSpot review)：一款出色的WiFi 分析和故障排除(WiFi analysis and troubleshooting)应用程序！
步骤 2(Step 2)。使用NetSpot查找您所在地区的WiFi网络（包括隐藏的SSID(SSIDs)）
当您启动NetSpot时，您会看到一个提示，鼓励您将许可证升级到PRO。按继续(Continue)，您可以根据需要免费使用该应用程序。
等待(Wait)几秒钟，直到它分析您所在地区的无线频谱(wireless spectrum)并显示它找到的WiFi 网络(WiFi network)。对于您所在地区的每个WiFi 网络(WiFi network)，您会看到：
- 其 SSID 或网络名称
- 发出信号的路由器或无线接入点(access point)的MAC 地址(MAC address)
- 网络的别名（由您设置）
- 带有信号强度历史的图表(strength history)
- 以 dBm 为单位测量的当前信号强度，最小、最大和平均信号，网络信号的电平(network signal)
- 发射信号的无线频段、使用的频道以及(wireless band)频道(frequency channel)的宽度（20、40 或 80 MHz），
- 发射无线信号的设备的供应商
- 使用的安全性或加密类型
- 用于网络的无线模式(wireless mode)或标准：802.11ac、802.11n 等。
- 您所在地区最后一次看到该网络的时间。
向下滚动(Scroll)WiFi SSID(WiFi SSIDs)列表，看看NetSpot发现了什么。写下(Write)你感兴趣的那些。然后，在您的Windows 笔记本电脑或平板电脑(Windows laptop or tablet)上，单击或点击任务栏系统托盘区域中的WiFi 图标(WiFi icon)。您会看到一个列表，其中包含所有未隐藏的无线网络。
将NetSpot(NetSpot)中的 SSID列表与Windows显示的SSID(SSIDs)列表进行比较，那些仅显示在NetSpot中的 SSID被其所有者隐藏。在我们区域，Netspot共检测到 22 个SSID 或网络名称(SSIDs or network names)。相比之下，Windows 10 仅检测到 12 个无线网络。我们地区的十个无线网络是隐藏的。我们能够看到关于他们的各种有趣的信息。例如，我们知道他们使用哪种加密方式，用于广播WiFi 信号的无线网络标准(WiFi signal)(802.11ac/n/b/g)，或上次检测到网络的时间。其中一些信号微弱，不断从雷达上消失。
您从NetSpot(NetSpot)获得的另一条有用信息是使用多个网络地址广播网络名称(network name)时。使用无线中继器或网状WiFi(WiFi)系统时就是这种情况。如果您仔细分析NetSpot提供的数据，您将准确了解您所在地区的无线架构。
如果您需要有关NetSpot显示的所有技术术语的帮助，请阅读此有用的用户文档：NetSpot 和 Wi-Fi 相关科学中使用的所有聪明词(All the clever words used in NetSpot and Wi-Fi related science explained)。
你发现了多少隐藏的无线网络？
正如您从本指南中看到的，NetSpot是一个有用的应用程序，可让您发现您所在地区的所有无线网络。在我们的公寓楼里，我们发现了两个隐藏和开放的无线网络，没有设置密码。他们的主人认为，如果他们隐藏了自己的WiFi网络，就不会被其他人发现和使用。他们错了，你不应该效仿他们。使用正确的工具，任何人都可以发现您隐藏的 WiFi 以及(hidden WiFi and lots)有关其设置方式的大量详细信息。在结束本教程之前，请与我们分享您在您所在地区发现的示例。我们很想知道你的故事。
How to find hidden wireless networks (SSIDs) in your area, in Windows
You might need to find all the wireless networks that are broadcast in уour area, includіng those which have a weak WiFі signal and those that hаve hidden their SSID (network name). For this tаsk, you have to install a wіreless network scanner аnd uѕe it to identify the WiFi networks which exist in your areа. However, many of thеse tools are еxpensiνe and only a few of them are free and work well. In this tutorial, we show you a tool that works in all versions of Windows, for free. Let's get started:
Step 1. Download and install NetSpot (free hidden wifi finder)
The first step is to download and install NetSpot FREE edition, from this page. Install the app. Follow the setup instructions and the installation is over in a couple of seconds.
Then, launch Netspot. You can use this app for free if all you want is to discover the WiFi networks in your area and analyze them. If you desire advanced features like advanced visual analysis and planning of wireless networks, you need to purchase the PRO version. You can find more about Netspot, and why it is an excellent choice, from this review: NetSpot review: a great app for WiFi analysis and troubleshooting!
Step 2. Use NetSpot to find the WiFi networks in your area (including hidden SSIDs)
When you start NetSpot, you see a prompt that encourages you to upgrade your license to PRO. Press Continue and you can use the app for free, as long as you want.
Wait for a couple of seconds until it analyzes the wireless spectrum in your area and it displays the WiFi networks that it finds. For each WiFi network in your area, you see:
- its SSID or the network name
- the MAC address of the router or wireless access point that is emitting the signal
- the alias of the network (set by you)
- a graph with the signal strength history
- the current signal strength measured in dBm, the minimum, maximum and average signal, the level of the network signal
- the wireless band on which signal is emitted, the channel used, and the width of the frequency channel (20, 40 or 80 MHz),
- the vendor of the device emitting the wireless signal
- the security used or the type of encryption
- the wireless mode or the standard used for the network: 802.11ac, 802.11n, etc.
- when the network was last seen in your area.
Scroll down the list of WiFi SSIDs and see what NetSpot has discovered. Write down those that interest you. Then, on your Windows laptop or tablet, click or tap the WiFi icon in the system tray area of the taskbar. You see a list with all the wireless networks that are not hidden.
Compare the list of SSIDs in NetSpot with those displayed by Windows, and those that show up only in NetSpot, are hidden by their owners. In our area, Netspot has detected a total of 22 SSIDs or network names. By comparison, Windows 10 detected only 12 wireless networks. Ten wireless networks in our area are hidden. We were able to see all kinds of interesting information about them. For example, we know what kind of encryption they are using, the wireless networking standard used for broadcasting the WiFi signal (802.11ac/n/b/g), or when the networks were last detected. Some of them had a weak signal and kept disappearing from the radar.
Another useful piece of information that you get from NetSpot is when a network name is broadcast using many network addresses. This is the case when using wireless repeaters or mesh WiFi systems. If you carefully analyze the data offered by NetSpot, you get an accurate understanding of the wireless architecture in your area.
If you need help with all the technical terms displayed by NetSpot, read this helpful user documentation: All the clever words used in NetSpot and Wi-Fi related science explained.
How many hidden wireless networks did you find?
As you can see from this guide, NetSpot is a useful app that allows you to discover all the wireless networks in your area. In our block of flats, we discovered two wireless networks which are hidden as well as open, with no password set. Their owners thought that, if they hid their WiFi networks, they cannot be found and used by others. They are wrong, and you should not follow their example. With the correct tools, anyone can discover your hidden WiFi and lots of details about how it is set up. Before closing this tutorial, share with us examples about what you have found in your area. We are curious to know your story.
