Modern smartphones offer many ways to connect to wireless networks, but technology WPS (Wi-Fi Protected Setup) remains one of the fastest methods for those who do not want to enter long passwords manually. This feature allows you to establish a secure connection between your device and the router with literally one click or using a short digital code. However, starting with Android 9, many manufacturers have removed the visual button from the interface, which raises questions among users.
Despite changes in Google's security policy, the mechanism of the protocol at the system level remains the same, and you can connect even without a displayed button in the settings. In this article we will look in detail at how Wi-Fi Protected Setupit works, what activation methods exist on different versions of the operating system, and why some experts recommend using this function with caution. You will learn about the nuances of working with physical buttons on routers and software solutions for old and new smartphones.
Understanding the principles of wireless communications will help you not only quickly get online, but also correctly set up your home network. We will consider both standard use cases and non-standard situations when the function is hidden or disabled by default. Are you ready to understand all the intricacies of connection? Let's start with the basic concepts.
What is WPS technology and how does it work
Abbreviation WPS stands for Wi-Fi Protected Setup. It is a networking standard designed to simplify the process of creating a secure home wireless network. The main idea of the technology is that the user can connect a new device to the router without entering a complex encryption key manually. Instead, automatic data exchange is used between the client (your smartphone) and the access point.
There are two main authentication methods within this protocol. The first method is to use a physical or virtual button. When you activate the mode on both devices, they begin searching for each other and automatically exchange encryption keys WPA2 or WPA3. The second method involves entering a PIN code. An eight-digit code is generated on the smartphone screen, which must be entered into the control panel of the router, or vice versa, a static code from a sticker on the router case is entered into the phone.
The protocol works at the level of wireless adapter drivers, which makes the connection process extremely fast. Usually the entire procedure takes no more than 30 seconds. However, it is important to understand that for successful pairing, both devices must support this standard. Most modern routers have this function, but in smartphones the situation is ambiguous due to changes in security requirements.
⚠️ Attention: WPS technology has known vulnerabilities associated with brute force selection of the PIN code. If your router is within the reach of others, it is recommended to disable the WPS function in the router settings after the initial setup of all devices.
Use the button (PBC) method instead of entering a PIN code, as it is considered more secure and is not susceptible to brute-force attacks.
Checking whether the function is supported on your smartphone
Before trying to connect, you need to make sure that your mobile device is technically capable of performing this operation. In older versions of Android, up to and including the eighth, support was native and displayed as a separate button in the Wi-Fi menu. In newer versions, Google has removed this interface element, but the connectivity itself is often retained in the system core.
To check the availability of the function, go to Settings → Network and Internet → Wi-Fi. Click the gear icon next to your network or open the advanced settings menu (three dots in the corner). If you see item WPS or WPS button, it means your phone is completely ready for use. If there is no such item, this does not always mean a lack of support.
Many manufacturers, such as Samsung, Xiaomi or Huawei, may hide this option in their shells, but leave it accessible through special menus or third-party utilities. It's also worth checking the specifications of your model on the official website. Sometimes support depends on the specific wireless chipset installed in the device.
| Android version | Presence of a button in the menu | Connection method | Recommendation |
|---|---|---|---|
| Android 8 and below | Yes | Direct click | Use the standard menu |
| Android 9 - 11 | Often hidden | Through advanced settings | Check availability in the menu Wi-Fi |
| Android 12+ | Absent | QR code or application | Use alternative methods |
If you haven’t found the treasured button, don’t rush to get upset. There are workarounds that allow you to initiate a connection even in the absence of an explicit interface. The main thing is to know where to look for the hidden capabilities of your system.
Classic method of connecting via a button
The simplest and most common algorithm of actions involves the presence of a physical button on the body of your router. It is usually indicated by an icon resembling two arrows forming a circle, or an inscription WPS. On some models, this function is combined with the reset button (Reset), so you need to press it briefly, without holding it down for a long time.
The connection process is as follows. First, you need to enable search mode on your router. Press the corresponding button on the device body. The Wi-Fi indicator will begin to flash quickly, signaling that the router is ready to pair. You have approximately two minutes to complete the procedure on the smartphone side.
Next, take the phone and open the wireless network settings. If you have a WPS button on the interface, click it. The system will automatically search for available access points in pairing mode. As soon as the connection is established, the indicator on the router will stop blinking and light up steadily, and a connection notification will appear on the phone screen.
☑️ Connection algorithm via button
It is important to follow the sequence of actions. If you first press a button on your phone and then spend too long searching for a button on your router, your session may expire. The protocol is designed for rapid interaction between devices in close proximity to each other.
⚠️ Attention: Do not hold the WPS button on the router for more than 5 seconds. A long press can activate factory reset mode, which will lead to the loss of all Internet configurations.
Connecting using a PIN code
The second authentication method requires entering a digital combination. This method is useful in cases where physical access to the router is difficult, for example, if it is mounted high on the wall or is located in another room. However, for this method, you will need to access the router's web interface from any device already connected to the network.
On your smartphone, in the WPS menu, select the option Entering a PIN code or Connect via PIN. An eight-digit set of numbers will appear on the screen. Write it down or remember it. Now open a browser on a computer or another phone, enter the router’s IP address (usually 192.168.0.1 or 192.168.1.1) and enter the control panel.
In the wireless network settings, find the WPS section. There will be a field for entering the customer PIN. Enter the numbers you saw on the screen of your Android device and confirm the action. The router will check the code and, if it is correct, will provide access to the network. The whole process takes a little longer than the button method, but gives more flexibility.
What to do if the PIN code is not accepted?
If the router rejects the entered code, try regenerating it on your phone and entering it again. Also make sure that your router does not have MAC address filtering enabled, which can block new devices regardless of the connection method.
Some older router models have a static PIN code printed on a sticker on the bottom of the case. In this case, you will need to enter this code into the appropriate field on the smartphone screen, if the phone interface allows you to enter a PIN, and not just generate it. This is less common, but is still relevant for older equipment.
Solving the problem of the lack of a button in Android 9 and higher
Starting with the ninth version of the operating system, Google has excluded support for the WPS button method from the basic settings interface. This decision was dictated by security considerations, since the protocol was considered vulnerable. However, users are often faced with the need to connect devices that do not have a keyboard for entering a password, such as printers or IoT gadgets.
How to connect in such a situation? The most modern and secure analogue of WPS is a connection via QR code. Many new generation routers allow you to generate a QR code with encrypted network data directly in the admin panel or display it on the router’s smart display screen. You just need to point your smartphone camera at the code, and the connection will happen automatically.
If the QR code is not available, you can use third-party applications from the store Google Play. There are utilities that restore the functionality of the WPS button by accessing the system API directly. When installing such an application, you will need to grant it rights to change Wi-Fi settings. After launch, you will see that very treasured button that has disappeared from the standard menu.
Another option is to use the function Wi-Fi Easy Connect (also known as DPP), which replaces the outdated WPS. It is supported by the latest devices and provides a higher level of cryptographic security. Check if in your phone settings there is an option to add a network through scanning or a special DPP protocol.
On modern smartphones without a WPS button, the best solution is to scan the network QR code or use specialized WPS client applications from the Play Market store.
⚠️ Attention: Installing third-party applications to activate WPS requires advanced permissions. Download apps only from the official Google Play store and check reviews to avoid malware.
Troubleshooting and connection errors
Even if you follow all the steps correctly, the connection process may fail. One common reason is the distance between devices. The WPS protocol is sensitive to the signal quality at the time of the handshake. Make sure you are in the same room as the router and there are no thick concrete walls or metal barriers between the devices.
The problem may also lie in the security settings of the router itself. Some providers or advanced users disable WPS at the router firmware level. Go to your router settings and check if this feature is enabled. Sometimes rebooting the equipment helps: unplug the router for 10 seconds and plug it in again.
If the phone sees the network, but cannot connect via WPS, try forgetting this network in the Wi-Fi settings (Forget network) and repeat the procedure again. Accumulated cache errors may prevent a new secure connection from being established. In rare cases, resetting the network settings on the smartphone itself helps.
- 📶 Make sure that client isolation (AP Isolation) is not enabled on the router, which prevents devices from seeing each other.
- 🔄 Reboot both devices - the smartphone and the router - before rebooting attempt.
- 🔒 Check if your phone's MAC address is blocked in the router's filtering settings.
- 📵 Turn off VPN and proxy servers on your phone while connecting, they may interfere with local data exchange.
If all else fails, your hardware may be simply incompatible. Older routers may not support the encryption standards that newer phones require, and vice versa. In this case, the only option is to manually enter the password.
Why is the WPS indicator blinking but not connecting?
A long blink without connecting often means that the connection request was rejected due to an incorrect PIN code or timeout. Try resetting the session on the router by pressing the button again.
Questions and answers (FAQ)
Is it safe to use WPS on a permanent basis?
Using WPS on a permanent basis is not recommended due to the vulnerability of the PIN code method to brute force attacks. It is better to activate the function only when connecting a new device, and then disable it in the router settings. The physical button (PBC) method is safer, but also requires control.
Can I connect via WPS if I don’t know the Wi-Fi password?
Yes, this is the main advantage of the technology. You don't need to know or enter your wireless network password. The protocol automatically transfers encryption keys between the router and the phone upon successful authentication via a button or PIN.
Why is there no WPS button on my new phone?
Starting with Android 9, Google removed this button from the standard interface due to security concerns. Smartphone manufacturers follow these recommendations. To connect, use QR codes or third-party applications if critically necessary.
Does WPS work at 5 GHz?
Yes, WPS technology supports operation in both bands - 2.4 GHz and 5 GHz. However, some older routers may have limitations and only support the function in one of the bands. Check the specifications of your equipment.
What to do if the button on the router is not signed?
If the button does not have a WPS signature, look in the instructions for the router. Often this function is combined with other buttons, such as the Wi-Fi or reset button. Look for an icon in the form of two arrows forming a circle.
