It's quite common to need to connect a new device to a wireless network but forget the access key, even though the printer or multifunction device is already working successfully in the same environment. Many users mistakenly believe that if the multifunction device is connected to a router, the device "remembers" the password and can easily be accessed in the menu. Unfortunately, for security reasons, most modern printing equipment manufacturers do not allow the saved Wi-Fi password to be displayed in plain text on the display screen or in the web interface.
However, there are several effective ways to restore network access or bypass the problem using the router's functionality, physical buttons on the device, or specialized software utilities. Understanding WPS Operation Knowing the factory default codes can significantly simplify the process. In this article, we'll cover all the relevant methods, from simple button manipulation to more complex actions via the command line and the router's admin panel.
It is important to note that methods may vary depending on the manufacturer (HP, Canon, Epson, Brother) and the model of your device. Old models Connections without a display require a special approach, while modern touch panels offer more diagnostic options. We'll look at universal solutions that will help you restore the connection in the shortest possible time without calling a technician.
Using the WPS function to connect without entering a password
The easiest and most often ignored way to connect an MFP to Wi-Fi without knowing the password is the technology WPS (Wi-Fi Protected Setup)This standard was developed specifically to simplify connecting devices to secure wireless networks. If your router and multifunction device support this feature (and almost all models released in the last 10-12 years do), you won't need to enter a complex security key at all.
The activation process usually takes no more than a minute. You need to find the button that says WPS On the router body. On some models, it may be combined with a reset button or have an icon resembling two arrows forming a circle. Pressing this button on the router puts it into device search mode. Then, you need to perform a similar action on the printer itself. Interfaces may vary: on models with a screen, this is often a menu item. Network settings, and on budget models - a separate physical button.
⚠️ Important: The WPS function is only activated for a short period of time (usually 2 minutes). If you don't press the button on the second device, you'll have to start the process over again. Make sure the MFP is within range of the router's signal.
There's also a PIN code method, which is a variation of WPS. In this case, an eight-digit code is generated on the printer screen (or in the printed configuration report). This code must be entered in the router's web interface under WPS. After verification unique identifier The router will automatically transmit the necessary connection data. This method is especially convenient if physical access to the back of the router is difficult.
Resetting the printer's network settings to factory defaults
If the previous method didn't work or your device doesn't support WPS, you may need to perform a full network reset. This will reset the Wi-Fi module to its default state, after which you can set up the connection again using a computer already connected to the network. It's important to understand that reset settings does not delete your documents or scans, it only affects the connection settings.
On most HP, Canon, and Epson devices, the procedure is performed using a key combination. For example, on HP printers, you often need to simultaneously press and hold buttons. Wireless communication And Cancel (or Information) for 3-5 seconds until the indicators start flashing. For Brother devices, you may need to enter the menu via the button Menu, go to section Network and select an item Reset Network. It is better to look for the exact combination for your model in the instructions, since reset algorithms vary greatly.
After the reset, the printer will enter setup mode. At this point, it can create its own access point (Direct), which can be connected to from a smartphone or laptop. Using a special app from the manufacturer (for example, HP Smart, Canon PRINT, Epson iPrint), you can transfer your home Wi-Fi password to the printer directly from your phone. This eliminates the need to manually enter the key on the device's small screen.
☑️ Checklist before resetting settings
Viewing the password through the router's web interface
Since the printer itself doesn't display the password, the most logical place to look is where it's stored—in your router's settings. If you have a computer already connected to Wi-Fi (either via cable or wireless), you can find the security key through the router's operating system or admin panel. This is the most reliable way to find out. Current Password, which uses your MFP.
To access your router settings, open your browser and enter the gateway IP address in the address bar. This is most often 192.168.0.1 or 192.168.1.1The exact address is often written on a sticker on the bottom of the router. You will need to enter the administrator login and password (often by default admin/admin). After logging in, find the section related to wireless networking (Wi-Fi, WLAN). In the Security subsections, a field will be displayed PSK Password or WPA Key.
Some router firmware versions hide passwords behind asterisks. In this case, you can use the "Show Password" feature (the little eye) or, if there's no such feature, simply change the password to a new one you'll definitely remember. After changing the router password, you'll still need to reconnect all devices, including the MFP, using the new key. This is a good opportunity to set a more complex and secure encryption key.
⚠️ Note: Router interfaces (TP-Link, Asus, D-Link, Keenetic) are constantly being updated. The menu layout may differ from what's described. Look for sections labeled "Wireless," "Security," or "WLAN." If you're unsure of what you're doing, it's best not to change the router's global settings to avoid disrupting other devices.
Using a USB cable for initial setup
Many users forget that most modern MFPs allow you to set up a Wi-Fi connection via a USB cable using a Windows or macOS computer. This method is ideal when you don't know the password, but your PC is already connected to the network. Drivers and setup utilities can "copy" network settings from your computer to the printer.
To begin, connect the MFP to your computer via a USB cable (usually type AB, square connector). Turn on the device and wait for the drivers to install. Then, run the setup program that comes with the drivers, or download the full version from the manufacturer's website. During the installation, select the "Wireless" or "Wi-Fi" connection type. The program will detect that the printer is connected via USB and offer to transfer the network settings.
The system will automatically retrieve your current Wi-Fi network parameters (SSID and security key) from the Windows registry or macOS keys and transfer them to the printer module. After successful data transfer, the program will prompt you to disconnect the USB cable. From this point on, the MFP will operate independently using the transferred data. network credentialsThis method often works where other methods fail, as it eliminates the human factor when entering characters.
What should I do if my computer doesn't see my printer via USB?
Make sure the cable is in good condition and no longer than 1.8 meters. Try connecting the cable to a different USB port, preferably directly to the motherboard (at the back of the system unit), bypassing USB hubs. Also, check Device Manager for any unknown devices with an exclamation mark. You may need to manually install the printer chipset driver.
Standard Action Table for Popular Brands
Different manufacturers use their own logic to control network functions. To make things easier, we've compiled a summary table of actions for the most common brands. Please note that on models without a display, LEDs flash, and the number of flashes may indicate the connection status.
| Brand | Network reset method | Customization application | Peculiarity |
|---|---|---|---|
| HP | Wireless + Cancel button (5 sec) | HP Smart | Often requires creating an HP account |
| Canon | Direct Connection Button (Phone Icon) | Canon PRINT Inkjet/SELPHY | Uses Direct mode to transmit password |
| Epson | Menu → Wi-Fi Setup → Reset Network | Epson iPrint / Smart Panel | Wi-Fi Direct support on most models |
| Brother | Menu → Network → Network Reset → Yes | Brother iPrint&Scan | Requires confirmation of reset by pressing the OK button |
| Pantum | Hold the Wi-Fi button (7 sec) | Pantum Mobile Print | Indication by flashing green indicator |
Using branded applications is the most modern approach. Applications HP Smart, Canon PRINT Others use Bluetooth or a direct Wi-Fi connection to detect the printer. They read the list of available networks from your smartphone and prompt you to select yours. The password is entered once on the phone, and the device is configured automatically. This eliminates the need to search for complex key combinations.
Diagnosing and resolving connection problems
Even if you know the password or use WPS, you may encounter difficulties. Often, the problem lies not in the password itself, but in frequency range or security settings. Most budget and mid-range MFPs only support the 2.4 GHz standard. If your router only broadcasts 5 GHz or uses a complex encryption protocol (such as pure WPA3), the printer simply won't see the network or won't be able to authenticate.
Check the printed network configuration report. On most devices, this can be done by pressing the "Information" button or through the menu. The report will show the IP address (if the connection is successful) or an error code. Error codes like "Auth Error" or "No Network" clearly indicate a problem with the security key or router visibility. Make sure MAC address filtering isn't enabled on the router, which could block the new device.
If all else fails, there's a "nuclear option"—temporarily using your smartphone as a hotspot. Create a network on your phone with the exact same name (SSID) and password as your home router. Turn on the printer near your phone. If it automatically connects to this "fake" network, the issue is definitely with the router's compatibility or signal strength. This method also rules out a faulty Wi-Fi module within the MFP itself.
⚠️ Please note: Router specifications and network security requirements are constantly changing. If your router is very old or, conversely, a newer one that only supports WPA3, conflicts may occur. In such cases, we recommend checking the router manufacturer's website for firmware updates that may add support for older Wi-Fi standards for printers.
Frequently Asked Questions (FAQ)
Is it possible to find out the Wi-Fi password if the printer is already connected but there is no display?
The printer itself won't reveal the password, as it's stored in secure memory. However, if the printer is connected, the password is known to another device (for example, a Windows computer). You can view the saved password in the wireless network properties on your computer or in the router's web interface, as described in this article.
What should I do if the printer sees the network, but says "Connection error"?
Most likely, you entered the wrong password or selected the wrong encryption type. Check for case inconsistency. Also, try changing the router's security type from WPA3 to WPA2/WPA Mixed, as older printer modules often don't support newer security standards.
Will the printer reset its network settings if the power goes out?
No, Wi-Fi settings are stored in non-volatile memory. After powering on, the printer will automatically attempt to connect to the last known network. A reset occurs only through a special procedure via the menu or a button combination.
How do I connect a printer if it only supports 2.4 GHz and my router only supports 5 GHz?
A direct connection is not possible. You need to go to your router settings and enable the 2.4 GHz band. Most modern routers are dual-band. If you really only have 5 GHz, you'll need to replace your router or buy a separate 2.4 GHz access point.
