Introduction

Connecting a new device to your wireless network should be simple, but anyone who has tried to type a 20-character WiFi password on a tiny printer screen or a smart camera knows that it rarely is. Between uppercase letters, lowercase letters, numbers, and symbols, manual entry is tedious and error-prone. That is where WiFi Protected Setup, better known as WPS, comes in.

If you have ever looked at your router and wondered What Does Wps Do on Wifi?, the short answer is that it is a one-touch or push-button system designed to help devices join a secure wireless network without requiring you to type the network password. Instead of hunting for the sticker on the bottom of your router and carefully entering every character, you press a button or enter a short code, and the devices handle the handshake automatically.

WPS has been around since 2006, and while it is incredibly convenient, it is also a topic of debate among security professionals. Some love it for ease of use; others warn that it can open doors for attackers if left enabled unnecessarily. In this guide, we will cover exactly what WPS does, how it works, the different ways to use it, how to set it up step by step, the security trade-offs involved, and when you might want to turn it off entirely.

What Does Wps Do on Wifi?

To understand What Does Wps Do on Wifi?, it helps to start with the full name: Wi-Fi Protected Setup. WPS is a network security standard created by the Wi-Fi Alliance in 2006. Its primary purpose is to simplify the process of connecting devices to a secure wireless network that uses WPA or WPA2 Personal encryption.

Normally, joining a WiFi network requires two pieces of information: the network name (SSID) and the pre-shared key (password). WPS removes the need for the user to manually type that password on the connecting device. Instead, WPS automates the exchange of credentials between the router (the access point) and the client device (your phone, printer, camera, or laptop).

When WPS is activated, the router and the device perform an authenticated handshake. During this handshake, the router securely transmits the SSID and encryption key to the device. Once the exchange is complete, the device saves those credentials and connects to the network automatically in the future.

It is important to note that WPS is not a type of WiFi encryption itself. It does not replace WPA2 or WPA3. Rather, it is a provisioning method—a way to get a device onto an already-secured network without exposing the password to the user during setup.

WPS is built into most consumer-grade wireless routers, access points, range extenders, printers, scanners, cameras, and many smart home devices. If you see a button labeled WPS or a symbol that looks like two arrows forming a circle, that device supports WPS.

How WPS Works: The Technology Behind One-Touch Setup

At a technical level, WPS relies on two roles: the registrar and the enrollee. The registrar is typically the wireless router or access point that already manages the network. The enrollee is the device trying to join the network, such as a smartphone or wireless printer.

When you initiate a WPS connection, the registrar and enrollee use the Extensible Authentication Protocol (EAP) to prove to each other that they are both WPS-capable. Once authenticated, the registrar sends the network credentials—SSID and passphrase—to the enrollee over a secure channel. The enrollee then configures its wireless adapter with those settings and associates with the access point.

The entire exchange is designed to happen quickly, usually within a two-minute window. After that window closes, the router stops listening for WPS requests until you trigger it again. This time limit is intentional: it reduces the opportunity for an unauthorized device to jump in and request credentials.

Depending on which WPS method you use, the authentication mechanism differs slightly. Some methods require physical proximity (pressing a button), while others rely on a numeric code. We will cover each method in detail in the next section.

WPS Connection Modes Explained

WPS supports several different connection modes. Not every router or device supports all of them, but most modern hardware supports at least one or two of the following:

Push Button Configuration (PBC)

Push Button Configuration is the most common and user-friendly WPS method. To use it, you press the WPS button on your router, then press the WPS button (or select the WPS option) on the device you want to connect. Both devices must be activated within about two minutes of each other.

Because this method requires physical access to both devices, it is generally considered more secure than the PIN method. An attacker outside your home cannot press your router’s button, so remote exploitation is much harder.

PIN Method

The PIN method uses an eight-digit number printed on a label on your router or displayed in its administrative interface. You enter this PIN into the device you want to connect, or you enter a device-generated PIN into the router’s settings. Once the PIN is accepted, the router sends the network credentials to the device.

While convenient, the PIN method is the most controversial from a security standpoint. The eight-digit PIN is not treated as a single eight-digit code. Instead, the router validates the first seven digits separately from the final checksum digit. This dramatically reduces the number of guesses an attacker needs to make, making brute-force attacks practical with widely available tools.

Near Field Communication (NFC)

Some older routers and devices supported WPS over NFC. With this method, you would tap the client device against an NFC tag on the router to instantly exchange credentials. NFC-based WPS never achieved widespread adoption and is rarely found on modern equipment.

USB Method

The USB method involved saving WPS network settings to a USB flash drive from the router, then plugging that drive into the client device to import the configuration. Like NFC, this method is largely obsolete and is not commonly supported on current routers or consumer devices.

WPS vs. Manual WiFi Connection: Comparison Table

To help you decide when to use WPS and when to enter your password manually, here is a side-by-side comparison.

Setup speed Very fast (under 30 seconds) Fast (requires typing an 8-digit PIN) Slower (requires typing full passphrase)
Password visible to user No No Yes
Physical access required Yes (router button) No (can be done over network) No
Resistance to brute-force attacks High Low High (depends on password strength)
Best suited for Printers, cameras, IoT devices Devices without a WPS button Phones, laptops, tablets
Works with WPA3 Limited / being phased out Limited / being phased out Yes
Risk if left enabled Moderate High None specific to setup method

How to Use WPS on Your Router: Step-by-Step

Before you can connect any client device, you need to activate WPS on your router. The exact steps vary slightly by manufacturer, but the general process is consistent across most brands.

  1. Locate the WPS button on your router. It is usually on the back or side panel and may be labeled “WPS,” “WiFi Protected Setup,” or marked with a symbol resembling two arrows in a circle.
  2. Make sure your router is powered on and broadcasting its wireless network.
  3. Press the WPS button once. On some models, you may need to hold it for two to five seconds. Watch the LED indicator; it should begin blinking, often in amber, blue, or white, to show that WPS mode is active.
  4. Once the LED starts blinking, you typically have a two-minute window to initiate the connection from your client device.
  5. If the connection succeeds, the LED will stop blinking and either turn off or return to a solid status light. If it fails, the LED will usually stop blinking after the timeout period, and you will need to start over.

Some routers also offer a virtual WPS button through a web-based administration panel or a mobile app. If your router does not have a physical WPS button, log into the router’s settings interface and look for a WPS or Wireless Setup section where you can start a push-button session.

How to Connect Devices Using WPS: Step-by-Step

After activating WPS on the router, you need to tell the client device to join using WPS. Here is how to do it on common device types.

Android Phones and Tablets

  1. Open the Settings app.
  2. Tap Network & internet, then tap Internet or Wi-Fi.
  3. Look for an option labeled “WPS Push Button” or “WPS PIN.” On some Android skins, you may need to tap the network name first and then select a WPS option.
  4. If using Push Button, tap the option and then press the WPS button on your router within two minutes.
  5. If using PIN, enter the eight-digit PIN found on your router’s label.

Windows Laptops and Desktops

  1. Select the WiFi icon in the system tray.
  2. Choose your network from the list.
  3. When prompted for a security key, look for an option that says “Connect using WPS” or “Press the WPS button on the router.”
  4. Press the WPS button on your router, then click Connect on your computer.

Wireless Printers and Scanners

  1. On the printer’s control panel, navigate to the Wireless or Network settings menu.
  2. Select WiFi Protected Setup or WPS.
  3. Choose Push Button Method if available.
  4. Press the WPS button on your router, then confirm on the printer.
  5. The printer should display a confirmation message once it obtains an IP address and connects.

Security Cameras and Smart Home Devices

  1. Open the companion app for your camera or smart device.
  2. Follow the in-app instructions to add a new device.
  3. When the app asks how you want to connect to WiFi, select WPS.
  4. Press the WPS button on your router when prompted by the app.
  5. Wait for the app to confirm that the device has joined the network.

Note about iOS: Apple iPhones and iPads do not support WPS natively. You cannot use the WPS button or PIN method to join a WiFi network on an iOS device. You must enter the WiFi password manually or use Apple’s password-sharing feature between iCloud devices.

WPS Security Risks and Vulnerabilities

While WPS solves a real usability problem, it has a well-documented security history. The biggest concern involves the PIN method.

Because the eight-digit WPS PIN is validated in two parts—the first seven digits and the final checksum digit—an attacker can crack the PIN much faster than they could crack a full WiFi password. Instead of guessing 100 million combinations, an attacker only needs to guess up to 10 million combinations for the first half and 10 possibilities for the second half. Tools such as Reaver and Bully can automate this process, sometimes recovering a WPS PIN in a matter of hours.

Once an attacker knows the WPS PIN, they can retrieve the network’s WPA or WPA2 pre-shared key, effectively learning your WiFi password. From there, they can join your network, potentially access shared devices, or monitor unencrypted traffic.

Push Button Configuration is less vulnerable to remote attacks because it requires someone to physically press a button on the router. However, it is not risk-free. If an attacker gains physical access to your router, or if they are inside your home during the two-minute WPS window, they could potentially add their own device to your network.

Some routers also have implementation flaws, such as failing to lock out WPS after several failed PIN attempts or allowing the WPS PIN to be retrieved remotely through the router’s web interface.

WPS Tips and Best Practices

If you choose to use WPS, following these best practices can help you enjoy the convenience without exposing your network to unnecessary risk.

  • Prefer Push Button over PIN. Whenever possible, use the physical WPS button rather than the eight-digit PIN. PBC requires physical presence and is far more resistant to brute-force attacks.
  • Disable WPS when you are not using it. If you only connect new devices occasionally, turn WPS off after setup is complete.
  • Keep your router firmware updated. Manufacturers occasionally release patches that improve WPS lockout behavior or fix known vulnerabilities.
  • Use a strong WiFi password anyway. WPS simplifies setup, but your network’s day-to-day security still depends on a strong WPA2 or WPA3 passphrase.
  • Secure physical access to your router. Place your router in a location where visitors or strangers cannot easily press the WPS button.
  • Do not rely on WPS as your only security measure. WPS is a convenience feature, not a replacement for encryption, strong admin passwords, or network segmentation.

When to Disable WPS

There are several situations where disabling WPS entirely is the smarter choice.

  • You never connect new devices using WPS and prefer to enter passwords manually.
  • You live in an apartment building or dense urban area where many devices are within range of your router.
  • You are running a home office or small business network where security requirements are higher.
  • Your router model has known WPS vulnerabilities and no firmware update is available.
  • You suspect that someone has already gained unauthorized access to your network.

To disable WPS, log into your router’s administration panel, navigate to the Wireless or WPS settings, and uncheck the option to enable WPS. Save your changes and reboot the router if necessary.

Alternatives to WPS

If you decide to turn off WPS, you still have several easy ways to get devices online.

  • QR code sharing: Many modern routers and smartphones can generate a QR code containing your WiFi credentials. A guest or new device can scan the code to join instantly without typing anything.
  • Manual entry: Typing the password remains the most universally compatible and secure method, especially for phones and laptops.
  • WPA3 Easy Connect (DPP): On newer WPA3 networks, Device Provisioning Protocol allows one device to provision another by scanning a QR code, replacing WPS with a more secure handshake.
  • Vendor apps: Smart home ecosystems like Google Home, Amazon Alexa, and Apple HomeKit often have their own guided setup flows that handle WiFi credentials securely without WPS.

Troubleshooting Common WPS Issues

Even when everything is supported, WPS does not always work on the first try. Here are some common problems and how to fix them.

WPS button pressed but nothing happens: Make sure you initiated the WPS connection on the client device within the two-minute window. If you waited too long, the router has already exited WPS mode and you need to press the button again.

LED blinks but the device does not connect: Move the device closer to the router to rule out signal interference. Also check whether your router has reached its maximum number of connected clients.

WPS PIN is rejected: Double-check the PIN on the router label. If the router’s WPS feature has been disabled in the admin panel, the PIN will not work. Some devices also generate their own PIN; in that case, you must enter the device’s PIN into the router’s settings, not the other way around.

Device connects but has no internet: This is usually not a WPS issue. It may be a DHCP problem, an IP address conflict, or the router may be blocking the device’s MAC address. Try restarting both the router and the client device.

Frequently Asked Questions

What Does Wps Do on Wifi?

WPS stands for Wi-Fi Protected Setup. It simplifies the process of connecting devices to a secure wireless network by automating the exchange of the network name and password. Instead of manually typing a long WiFi passphrase, you can press a button or enter a short PIN to let the router and device configure themselves.

Is WPS safe to use?

Push Button Configuration is reasonably safe for home use, especially if you only enable it briefly when adding a new device. The PIN method is less secure because it is vulnerable to brute-force attacks. For maximum security, disable WPS entirely when you are not actively setting up a new device.

Does WPS work with WPA3?

WPS was designed primarily for WPA and WPA2 networks. On WPA3 networks, the Wi-Fi Alliance promotes Easy Connect (Device Provisioning Protocol) as the successor to WPS. Some routers may still offer WPS on mixed WPA2/WPA3 networks, but native WPA3 setups typically use QR code-based provisioning instead.

Can I use WPS on iPhone?

No. Apple does not include WPS support in iOS or iPadOS. To connect an iPhone or iPad to a WiFi network, you must enter the password manually, use iCloud Keychain password sharing, or scan a WiFi QR code if your router supports it.

How do I turn off WPS?

Log into your router’s web interface or mobile app, find the Wireless or WPS settings section, and disable the WPS option. The exact location varies by manufacturer, but it is often under Advanced Wireless Settings.

What is the WPS PIN?

The WPS PIN is an eight-digit number printed on a label on your router or displayed in its administration interface. It is used to authenticate a client device during WPS setup. Because of security weaknesses, many experts recommend avoiding the PIN method and using Push Button Configuration instead.

Why is my WPS not working?

Common causes include missing the two-minute activation window, WPS being disabled in the router settings, device incompatibility, or signal interference. Try restarting both devices and repeating the process, ensuring you press the router’s WPS button first and then activate WPS on the client device immediately afterward.

Does WPS expose my WiFi password?

During normal operation, WPS does not display the password to the user. However, if an attacker successfully cracks the WPS PIN, they can retrieve the network’s pre-shared key. This is why the PIN method is considered a security risk.

Should I press WPS on the router or device first?

It is generally best to press the WPS button on the router first, then activate WPS on the client device within two minutes. Some devices allow either order, but starting with the router ensures the two-minute window is open when the client is ready.

Is WPS the same as WPA2?

No. WPA2 is an encryption standard that protects data traveling over your WiFi network. WPS is a setup standard that helps devices join a WPA2-protected network without typing the password. They work together, but they serve completely different purposes.

Conclusion

So, What Does Wps Do on Wifi? In short, it removes the friction of joining a secure wireless network. By automating the exchange of your network name and password, WPS lets you connect printers, cameras, smart home gadgets, and other devices with the press of a button or the entry of a short code. For households with lots of wireless gear, that convenience is genuine and valuable.

However, convenience comes with trade-offs. The WPS PIN method has known vulnerabilities that can expose your network password, and leaving WPS enabled indefinitely increases your attack surface. The best approach for most users is to use Push Button Configuration sparingly, disable WPS when it is not needed, and rely on strong WPA2 or WPA3 encryption for day-to-day security.

As newer standards like WPA3 Easy Connect become more common, WPS may eventually fade away. Until then, understanding how it works—and how to use it safely—gives you the best of both worlds: easy device setup without compromising your home network.
