Many users find themselves in a situation where they need to quickly share internet with a new device but don't have time to enter complex passwords. The question of which button to press on the router to connect to Wi-Fi becomes especially pressing in these situations. The answer depends on what you want to do: simply turn on the wireless network if it's disabled, or activate quick pairing mode without entering a security key.
In most cases, the button marked with is responsible for activating the wireless module. WLAN, Wi-Fi or an antenna icon. However, on modern routers, such as Asus, TP-Link or Keenetic, the button functionality is often programmable and depends on the duration of the press. A short press can simply turn the signal emission on and off, while a long press initiates the mode WPS for automatic connection of gadgets.
It's important to understand that the physical presence of a button on the router's body doesn't always guarantee that it will work out of the box for internet sharing. Often, this button only toggles the status of an already configured network. If your router is brand new, you'll first need to perform basic setup via the web interface, and only then can you switch to manual mode via the button on the router's body.
Differences between WLAN, WPS, and Reset buttons
There are usually a number of buttons on the back or bottom panel of the router, and it is easy for an inexperienced user to confuse their functions. Button WLAN (or Wireless) is used to physically turn the wireless module on or off. If the Wi-Fi lights on the router are off, the network is likely disabled by software or this button, and pressing it once should restore the signal.
The button works completely differently. WPS (Wi-Fi Protected Setup). Its main purpose is to simplify the setup of a secure network. When you press this button, the router goes into search mode for devices that want to connect without entering a password. This is convenient for printers and TVs. Samsung or LG, as well as for network expansion via repeaters. However, caution is advised: WPS mode is often criticized by security experts for its protocol vulnerabilities.
⚠️ Caution: Never press and hold the small recessed button for 10-15 seconds unless you plan to perform a full factory reset. A long hold will often activate the function. Reset, which returns the router to factory settings, deleting all your passwords and provider configurations.
Some manufacturers, for example, Zyxel or Mikrotik, making the buttons multifunctional. A short press can turn on Wi-Fi, while a double press can launch a guest network. To avoid guesswork, it's best to consult the documentation for your specific model or look at the icon next to the button: a two-arrow icon usually indicates WPS, while an antenna icon indicates the module's power supply.
Using WPS technology for quick connection
Technology WPS It was developed to allow users to connect devices to a Wi-Fi network without having to manually enter a long and complex password. This is especially useful for devices with cumbersome input interfaces, such as Smart TVs, game consoles, or printers. To use this method, the router must have a dedicated button, and the connecting device must support this standard.
The connection process looks like this: you find the button WPS on the router body and press it (sometimes you need to hold it for 2-3 seconds). The WPS indicator on the router will begin blinking, indicating that the device is waiting for a connection. Within the next 2 minutes, you must start a network search on the client device and select the WPS connection option.
- 📡 Automatic key transfer: The router itself transmits the encrypted password to the device; the user does not need to know the secret combination of characters.
- 🔒 Connection security: The protocol uses secure data exchange, although it is considered less secure than manually entering a complex WPA3 password.
- ⏱ Time limit: The standby mode is usually active for no more than 120 seconds, after which the button must be pressed again.
It is worth noting that on some modern router models, for example, from Asus with firmware AsuswrtFor security purposes, the WPS function can be completely disabled through the web interface. If the button on the router doesn't respond, the function may be disabled by software. In this case, you'll need to access the router settings through a browser at 192.168.0.1 or 192.168.1.1.
What to do if WPS doesn't work?
If the WPS button is present but the connection fails, check to see if the maximum number of connected devices has been reached. WPS may also not work if MAC address filtering is enabled on the router or if the encryption type is only WPA3, which is not always compatible with the older WPS standard. Try updating your router's firmware.
How to turn on Wi-Fi with a button if it is turned off
There are situations when the Wi-Fi network suddenly disappears, even though the cable connection works. This often happens due to an accidental button press. WLAN on the router body, especially if it's inconveniently located. In this case, the wireless module is physically disabled, and devices can no longer see the network. To fix this, find the button with the image of an antenna or the text Wireless.
Press this button once briefly. Note the LED indicators on the front of the device. If Wi-Fi was turned off, the indicator indicating the wireless network should light or flash after 10-20 seconds. On routers TP-Link it's usually an antenna icon, Keenetic — the letter "a" or a specific wave symbol.
If a short press doesn't help, the button's function may have been reassigned in the settings. Some users specifically program the button to perform other actions, such as switching DNS profiles or starting a VPN. In this case, enabling Wi-Fi is only possible through the web interface. Go to Home network or Wi-Fi network and make sure that the "Turn on wireless network" box is checked.

Button mapping table for popular brands
Since network equipment manufacturers use different labeling standards and button logic, a summary table is provided below. It will help you determine which button to press on your device to perform the desired action.
| Router brand | Wi-Fi power button | WPS button | Features of work |
|---|---|---|---|
| TP-Link | WLAN / Wi-Fi | WPS | A short press on the WLAN button turns the network on/off. A short press on the WPS button turns the network on/off, while a long press on the WPS button turns the network off. |
| Asus | Wi-Fi (often combined) | WPS | Often, one button controls both modes. The short press is for WPS, and the long press (3 seconds) is for Wi-Fi on/off. |
| Keenetic | Fn + Wi-Fi (in the menu) | Separate or Fn | The Wi-Fi button on the case is often programmable. By default, it can turn on the guest network. |
| D-Link | Wi-Fi | WPS / Q1 | Separate buttons. The indicator flashes when the connection mode is active. |
| Tenda | WPS / Wi-Fi | WPS | A frequently combined function. Holding it for 5 seconds can reset the settings. |
For example, on routers Keenetic The button with the star or globe icon can be reassigned to launch any scenario. Therefore, if the default actions don't work, it's worth checking the settings in your device's personal account.
⚠️ Note: Interfaces and button behavior may change with firmware updates. If the steps described above don't work, check the manufacturer's official website for the latest instructions for your software version.
What to do if the button is not responding or is broken
Button wear is a common problem with routers that have been in continuous use for years. If you press the Wi-Fi or WPS button but there's no response (no indicator lights, no devices connect), the contact block may be damaged. In this case, avoid applying excessive force to avoid pushing the button into the housing.
There is a software solution to this problem. You can access the router settings via a cable connection (LAN) or through the manufacturer's mobile app. In the control interface, usually in the "Settings" section System or Control, it is often possible to programmatically emulate a button press or simply enable the Wi-Fi module by checking the box.
- 📱 Mobile application: Use the manufacturer's app (eg. Tether for TP-Link or Asus Router) to turn on Wi-Fi remotely.
- 💻 Web interface: On the menu
Wireless modeUncheck and recheck the "Enable wireless broadcasting" box. - 🔄 Reboot: Sometimes the Wi-Fi module simply freezes. Unplug the router for 10 seconds and then plug it back in—this will restart all services.
If neither software nor gentle pressing helps, and you urgently need Wi-Fi, you can use a more workaround. On some models, you can short-circuit the button contacts on the board with a thin wire, but this requires disassembling the device and soldering skills, which is not recommended for regular users. It's easier to buy a USB Wi-Fi adapter for your PC and share the network through it, or buy a new router.
Configuring the button via the router's web interface
For advanced users, the ability to reprogram buttons is available. This allows you to assign a button WPS or Fn Any convenient function, such as quickly enabling a guest network or rebooting the router, can be configured through the device's web interface.
To access the button settings menu, enter the router's IP address in the browser's address bar (usually 192.168.0.1). After entering your login and password (indicated on the sticker on the bottom of the device), go to the section System tools or Additional settings. Look for a subsection Customizing buttons or Button Task.
Here you can select the action for short and long presses. For example, you can configure it to: single press to turn on Wi-Fi, double press to enable guest access. This makes network management more flexible and eliminates the need to access settings via a browser every time.
Approximate path in the Keenetic menu:Main Menu → System → Settings → Wi-Fi Button
Approximate path in the Asus menu:
Advanced Settings → Administration → System → WPS Button
After making changes, be sure to click "Save" or "Apply," otherwise the settings will be reset upon reboot. When experimenting with settings, write down the original values so you can revert them if you make a mistake.
Frequently Asked Questions (FAQ)
Is it possible to connect to Wi-Fi without pressing a button if I don't know the password?
Without knowing the password and being able to press the WPS button (or if it's disabled in the settings), it's impossible to connect to a secure network. This is the basic Wi-Fi security standard. The only legal way is to obtain the password from the network owner or connect via WPS if this feature is enabled and physically accessible.
Why is the WPS indicator on, but the internet isn't working?
The WPS indicator only indicates the pairing process or active connection standby mode. It does not guarantee internet access. If the internet is not working, check your ISP's cable (WAN), the connection status in the router's web interface, and your account balance.
Is it safe to keep the WPS button turned on all the time?
Constantly enabling WPS discovery mode reduces your network security by making it easier for hackers to guess your password. We recommend using the WPS button only when connecting a new device, and then disabling this feature in the router settings or waiting for it to automatically turn off sleep mode.
What should I do if after pressing the button the internet is lost on all devices?
You most likely accidentally activated the "Disable Wi-Fi" or "Airplane Mode" feature on your router. Try pressing the WLAN/Wi-Fi button again. If that doesn't help, you may have accidentally pressed the Reset button. In this case, you'll need to set up the router again as if it were new.
