您在设置Wi-Fi 路由器(Wi-Fi router)时一定遇到过WPS一词。它是路由器背面以太网电缆端口旁边的一个小按钮。尽管它几乎存在于所有无线路由器中，但只有少数人知道它的用途。他们不知道这个小按钮使设置无线网络变得如此容易。如果您仍然想知道这意味着什么，那么本文应该可以解决您的疑问。我们将详细讨论WPS是什么以及它是如何工作的。
什么是 WPS？(What is WPS?)
WPS 代表 Wi-Fi Protected System(WPS stands for Wi-Fi Protected System)，Wi-Fi 联盟(Alliance)首先创建它是为了让建立无线网络的整个过程变得简单易行。它使那些不那么精通技术的人的生活更轻松。在WPS之前的时代，您需要掌握大量有关Wi-Fi和配置模型的知识才能建立无线网络。
WPS技术适用于使用WPA Personal 或 WPA2 安全协议(WPA Personal or WPA2 security protocols)进行加密并使用密码保护网络的无线网络。但是，如果使用的安全协议是WEP ，则(WEP)WPS不起作用，因为它不是很安全并且很容易被黑客入侵。
每个网络都有一个特定的名称，称为SSID。要连接到网络，您需要知道其SSID和密码。以将手机连接到Wi-Fi网络的简单过程为例。您要做的第一件事是打开手机上的Wi-Fi并搜索可用网络。当您找到要连接的人时，点击它，然后输入密码。如果密码正确，则您将连接到设备。但是，通过使用WPS，您可以使此过程更加简单。这将在下一节中讨论。
WPS有什么用？(What is the use of WPS?)
如前所述，WPS 是路由器背面的一个小按钮(WPS is a small button at the back of the router)。当您希望将设备连接到Wi-Fi网络时，打开该设备上的Wi-Fi，然后按下WPS按钮。当您点击它时，您的设备现在将自动连接到网络。(. Your device will now be automatically connected to the network when you tap on it.)您将不再需要输入密码。
除了智能手机，很多无线设备如打印机都可以连接到Wi-Fi网络。这些设备上还带有WPS按钮。为了快速连接两个设备，您可以按下打印机上的按钮，然后按下路由器上的WPS按钮。(WPS)这很容易。无需输入SSID或密码。设备还将记住密码并从下次开始自动连接，甚至无需按下WPS按钮。

WPS连接也可以在 8 位PIN的帮助下进行。此方法对于没有WPS按钮但支持WPS的设备很有用。此PIN是自动生成的，可以从路由器的WPS配置页面查看。(WPS)将设备连接到路由器时，您可以输入此PIN，这将验证连接。
WPS 按钮在哪里？(Where is the WPS button situated?)
WPS是一种在设备之间建立无线连接的安全且简单的方法。由于大多数无线网络都使用 Wi-Fi 路由器，因此您会发现其中内置了WPS 。有些路由器甚至默认启用了WPS 。每个 Wi-Fi 路由器都带有WPS按钮或至少支持WPS。那些没有物理按钮的路由器需要使用路由器的固件配置WPS 。
如前所述，大多数无线路由器都有一个WPS 按钮，位于设备背面(WPS button located at the back of the device)靠近以太网端口的位置。确切的位置和设计因品牌而异。对于某些设备，单个按钮充当电源按钮和WPS按钮。简单的短按用于打开或关闭Wi-Fi，长按用于启用/禁用WPS。
您甚至可能会在设备背面找到一个没有标签的小按钮，该按钮仅带有WPS符号，或者在某些情况下；它可能出现在正面。找出确切位置的最佳方法是参考手册，如果仍然找不到，请咨询卖家或您的网络服务提供商。

What is WPS and How Does it Work?
You must have come aсroѕs the term WPS while setting up a Wi-Fi router. It is a small button next to the ethernet cable port on the back of the router. Although it is present in almost all wireless routers, only a few people know its purpose. They are unaware of the fact that it this small button that makes it so much easier to set up a wireless network. If you are still wondering what it means, then this article should solve your queries. We are going to discuss in detail what WPS is and how it works.
What is WPS?
WPS stands for Wi-Fi Protected System, and Wi-Fi Alliance first created it to make the entire process of setting up a wireless network simple and easy. It made to make lives easier for those people who aren’t that tech-savvy. In the times before WPS, you needed to possess a good deal of knowledge about Wi-Fi and configuration models in order to set up a wireless network.
WPS technology works with wireless networks that use WPA Personal or WPA2 security protocols to encrypt and a password to secure the network. WPS, however, does not work if the security protocol being used is WEP, as it is not very safe and can easily be hacked into.
Every network has a specific name, which is known as SSID. To connect to a network, you need to know both its SSID and its password. Take, for example, the simple process of connecting your mobile phone to a Wi-Fi network. The first thing that you do is switch on the Wi-Fi on your mobile and search for available networks. When you find the one that you wish to connect to, you tap on it and then enter the password. If the password is correct, then you will be connected to the device. However, with the use of WPS, you can make this process even simpler. This will be discussed in the next section.
What is the use of WPS?
As mentioned earlier, WPS is a small button at the back of the router. When you wish to connect a device to the Wi-Fi network, turn on Wi-Fi on that device and then press the WPS button. Your device will now be automatically connected to the network when you tap on it. You will no longer require to put in the password.
Apart from smartphones, a lot of wireless devices like printers can be connected to the Wi-Fi network. These devices also come with a WPS button on them. In order to quickly connect the two devices, you can press the button on your printer and then press the WPS button on your router. This is as easy as it gets. There is no need to enter the SSID or password. The device will also remember the password and automatically connect from the next time onward without even pressing the WPS button.

A WPS connection can also be made with the help of an 8-digit PIN. This method is useful for devices that do not have a WPS button but support WPS. This PIN is automatically generated and can be viewed from the WPS configuration page of your router. While connecting a device to a router, you can enter this PIN, and that will validate the connection.
Where is the WPS button situated?
WPS is a secure and easy means to establish a wireless connection between devices. Since most wireless networks use a Wi-Fi router, you will find WPS in-built in them. Some routers even have WPS enabled by default. Every Wi-Fi router comes with either the WPS button or at least support for WPS. Those routers that do not have a physical push button need WPS to be configured using the router’s firmware.
As mentioned earlier, most of the wireless routers have a WPS button located at the back of the device adjacent to the ethernet port. The exact position and design differ from one brand to the other. For some devices, a single button acts as the power button and WPS button. A simple short press is used to turn on or off the Wi-Fi, and a long press is used to enable/disable WPS.
You might even find a small unlabeled button with just the WPS symbol at the back of your device, or in some cases; it might be present on the front side. The best way to find out the exact location is to refer to the manual and if you still can’t find it, then consult the seller or your network service provider.

Which Devices support WPS?
Almost any smart device with Wi-Fi capability comes with WPS support. Starting from your smartphones to smart TVs, printers, gaming consoles, speakers, etc. can be easily connected to a wireless network using WPS. As long as the operating system on these devices supports WPS, you can connect them to your Wi-Fi network with a single push of a button.
Two of the most popular operating systems Windows and Android support WPS. All Windows operating system since Windows Vista comes with in-built support for WPS. In Android’s case, native support for WPS was introduced with Android 4.0 (Ice-Cream Sandwich). However, Apple’s Mac OS and iOS for the iPhone does not support WPS.
What are the Drawbacks of WPS?
One of the main drawbacks of WPS is that it is not very safe. As mentioned earlier, WPS uses an 8-digit PIN to establish a secure connection. Although this PIN is auto-generated and not used by people, there is a strong chance that this PIN can be cracked by hackers using brute force.
The 8-digit PIN is stored in two blocks of 4 digits each. This makes it easier to tackle each block individually, and instead of creating 8-digit combinations, two 4-digit combinations are more comfortable to crack. Using his standard brute force tools, a hacker can crack this code in 4-10 hours or a maximum of a day. After that, they can access the security key and gain complete access to your wireless network.
How to connect an Internet Capable device to a Router using WPS?
Internet-capable devices like smart TVs or Blu-ray disc player can be connected to a wireless router if both the device supports WPS. Follow the steps given below to establish a wireless connection between them.
- Firstly, make sure that your Wi-Fi router has a WPS button.
- After that, switch on your Internet-capable device and navigate to the network.
