The situation when after changing the Internet provider or buying a new router, your favorite MFP The problem of a computer losing network connectivity and refusing to print is familiar to many. Instead of the usual document, the output is silence, and an annoying connection error message pops up on the computer screen. At this point, users often panic, believing the device is broken, when in fact the problem lies solely in the network settings.
Restoring the connection between a printer and a wireless network is a technically simple process, but it requires attention to detail. Modern models from HP, Canon, Epson And Brother have an intuitive interface, but the algorithms for actions may differ significantly depending on the presence of a display on the case. Understanding the basic principles of operation DHCP protocol and authorization methods will help you avoid unnecessary calls to technical support.
In this article, we will look at all the current methods for restoring the connection: from automatic setup through WPS Before manually entering settings through the control panel, you'll learn how to properly reset network settings to avoid IP address conflicts and what nuances to consider when working with dual-band routers.
⚠️ Note: Menu interfaces and button layouts may vary depending on your specific device model. Always consult the manufacturer's official documentation if the default navigation paths differ from those described below.
Preparatory stage and reset
Before you begin the active setup phase, you need to make sure you have all the necessary information. You will need the exact name of your wireless network (SSID) and its password. If you've changed your router, this information may have changed, and the old password stored in the printer's memory is no longer relevant. Write it down on a piece of paper or keep it handy on your smartphone's screen.
A critical step is complete reset network settings The printer itself. Many users try to simply enter a new password over the old one, which often leads to configuration errors and address conflicts. A reset returns the device's network module to its original state, deleting old connection profiles.
- 🔌 Turn off the router and printer for 30 seconds, then turn on the router and wait until the network is fully loaded.
- 📱 Make sure your computer or smartphone is connected to the same Wi-Fi network you plan to connect your device to.
- 📄 Print a network configuration report (usually via the "Report" menu or a key combination) to see the current status.
The reset procedure varies. On devices with a screen, it's usually done through the menu. Settings → Network → Reset network settingsOn models without a display, you often need to hold down the wireless button or the cancel button for 10-15 seconds until the lights flash. After this, the device is ready to search for a new router.
Using WPS technology for quick setup
The fastest way to restore connection is to use technology WPS (Wi-Fi Protected Setup)This method allows devices to exchange passwords automatically, without having to manually enter complex character combinations using the navigation buttons. It's ideal if you don't have a cable or keyboard handy.
First, make sure your router supports this feature. Most modern models have a physical button with a corresponding label or a software button in the router's web interface. If your router is older or your ISP has disabled this feature, this method won't work, and you'll have to resort to manual configuration.
⚠️ Caution: WPS is considered less secure because it makes it easier for attackers to guess your password. If network security is a priority, use this method only temporarily or ensure WPS is disabled on your router immediately after connecting.
The process is simple: press the WPS button on the router (sometimes you need to hold it for a few seconds until the indicator light flashes). Then, within two minutes, press the wireless button on the printer. If the device has a display, select "Wi-Fi Protected Setup" in the network menu. The indicators will start flashing, indicating the pairing process.
- 🟢 The green Wi-Fi indicator is constantly on - the connection has been successfully established.
- 🔴 The indicator is blinking or red - the connection is not established, check the distance to the router.
- 🔵 The indicators are flashing alternately - data exchange is in progress, do not turn off the devices.
4 GHz. If your router only broadcasts on the 5 GHz band or uses "5 GHz Only" mode, automatic connection will not occur. In this case, you'll need to go to your router settings and enable the 2.4 GHz guest network or combine the bands.
What should I do if the WPS button on my router won't press?
Some providers (e.g., Rostelecom, Beeline) provide routers with the WPS button disabled by software. In this case, you need to log into the router's web interface (usually 192.168.0.1 or 192.168.1.1), find the Wireless or Wi-Fi section, and press the "Connect" or "WPS" button there.
Manual setup via the printer control panel
If automatic methods fail, you'll have to resort to the traditional method—manually entering data through the device's menu. This method is the most reliable and versatile, as it works on virtually any model, even with a minimal monochrome display. You'll need patience to navigate the menu using the arrow keys.
First, open the settings menu. The icon usually looks like a gear, wrench, or antenna. Find the section responsible for networking. It may be called Network, Wireless, Wireless communication or Wi-Fi settingsSelect "Wireless Setup Wizard".
The device will begin searching for available networks. In the list that appears, find your router's name (SSID). Note that if you have a dual-band router, you may see two similar names, for example, HomeWiFi And HomeWiFi_5GFor maximum compatibility with older printers, it's best to choose a network without a 5G prefix, that is, a range 2.4 GHz.
Menu sequence (example for HP):1. Settings (gear icon)
2. Network
3. Wireless communication
4. Wireless Setup Wizard
5. Select the network name from the list
After selecting a network, the system will ask for a password. Entering characters using the navigation buttons is a tedious process. Use the arrow keys to navigate through letters and numbers, and the OK or Enter — to confirm your character selection. Be careful with the case of the letters, as Wi-Fi passwords are case-sensitive.
Setup via USB cable and software
Entering a password using buttons on a small screen isn't for everyone. Fortunately, manufacturers have provided a more convenient method via a computer. To do this, you'll need a USB cable (usually Type-B, with a square connector, often included) and an installation disc or a driver downloaded from the official website. This method allows you to transfer Wi-Fi settings from your computer to the printer.
Download the full software for your model from the manufacturer's website. Don't use the basic Windows Update drivers, as they often lack the network configuration module. Run the installer and follow the on-screen instructions. When prompted for your connection type, select "Wireless" or "Wi-Fi."
At a certain point, the installer will ask you to connect the printer to your computer via a USB cable. Do so and wait for the system to recognize the device. The program will automatically read your PC's current network settings (network name and password) and transfer them to the printer's memory. Once successfully transferred, the program will prompt you to disconnect the USB cable.
| Manufacturer | Name of the utility | Peculiarities |
|---|---|---|
| HP | HP Smart / HP Utility | Automatically search for devices on the network |
| Canon | Canon IJ Network Tool | Requires manual port selection |
| Epson | Epson Net Config | A powerful tool for advanced settings |
| Brother | Brother iPrint&Scan | Convenient mobile and desktop versions |
This method is especially effective when the printer is far from the router and has poor signal strength during setup, but is close to a computer connected via cable. It also helps bypass problems with entering special characters in the password.

Problems with the 2.4 GHz and 5 GHz bands
One of the most common reasons why a printer doesn't detect Wi-Fi is incompatibility between frequency bands. The vast majority of printers (especially older and budget models) operate exclusively within the same frequency band. 2.4 GHzModern routers often operate in "Dual Band" mode, combining 2.4 and 5 GHz networks under a single name, or even hiding the 2.4 GHz network entirely.
If your router only broadcasts 5 GHz, the printer simply won't detect the network. You need to access your router settings (via a browser; the address is usually 192.168.0.1 or 192.168.1.1) and ensure the 2.4 GHz network is enabled. It's a good idea to give it a separate name, for example, by adding the suffix "_2.4," to ensure the printer connects to the correct channel.
It's also worth checking the security type. Printers may not support the latest encryption standards, such as WPA3If you're set to "WPA3 Only," try switching your router to a mixed "WPA2/WPA3" mode or temporarily to "WPA2-Personal (AES)." This often resolves the "invisible" network issue.
⚠️ Important: Wireless network settings, such as broadcast channels and channel width, may be changed automatically by the router. If the printer periodically loses connection, try setting a static channel (e.g., 1, 6, or 11) for the 2.4 GHz network in your router settings.
Another important consideration is hiding the SSID. If you hide your network name for security, the printer won't be able to find it when scanning. You'll have to either temporarily open the network or select "Add hidden network" in the printer menu and manually enter the name (SSID) down to the last character.
Diagnosing and troubleshooting connection errors
Even if you follow all the steps correctly, errors can still occur. Understanding the signals your device emits will help you quickly diagnose the problem. First, pay attention to the behavior of the indicator lights. If the Wi-Fi indicator blinks blue endlessly, this means the printer is trying to connect but is unable to complete the handshake with the router.
A common cause is filtering by MAC addressesIf your router has MAC filtering enabled, the new printer will be blocked even if the password is entered correctly. You need to find the printer's MAC address (usually on a sticker on the back or in the configuration report) and add it to the allowed list in the router settings.
Also, check if you've reached your maximum number of connected clients. Home routers can store up to 10-15 devices in memory. If you have a smart home with dozens of gadgets, the router may simply refuse to connect to new devices. Restarting the router in this case often frees up old, "hanging" sessions.
- 📉 Weak signal: The printer is too far from the router or behind thick walls. Try moving it closer.
- 🔄 IP conflict: Two devices on the network have the same IP address. Restarting the router will update the DHCP table.
- 🛡️ Antivirus blocking: The firewall on your computer may be blocking the printer from being detected on the network.
If all else fails, perform a full power cycle: turn off the router, turn off the printer. Turn on the router, wait 2 minutes, and then turn on the printer. This allows the printer's network module to correctly request a new IP address from the updated router pool.
How to find out the IP address of a printer?
Print the Network Configuration Page. In the IPv4 section, you'll see an address such as 192.168.1.45. Enter this address into the address bar of your computer's browser. This will open the printer's web interface (EWS), where you can check the connection status in detail.
Why doesn't the printer see the 5 GHz network?
Most printers are equipped with older 802.11 b/g/n radio modules, which are physically unable to operate in the 5 GHz frequency range. They require a 2.4 GHz network. Make sure your router broadcasts in this range and that your network isn't hidden.
Can I connect a printer to guest Wi-Fi?
Technically yes, but it's a bad idea. Guest networks often have client isolation, which prevents devices within the network from "seeing" each other. The computer simply won't be able to send a print job because it won't find the printer on the local network.
What is Wi-Fi Direct and do I need it?
Wi-Fi Direct allows you to print without a router by connecting your phone and printer directly. This is convenient for printing photos from a smartphone, but for desktop printing in the office or at home, it's better to use standard Wi-Fi through a router so that the printer is accessible to all devices in the house.
How do I reset my network settings if I forgot my menu password?
The password for the printer's settings menu (not the Wi-Fi password) is often blank by default or set to "0000," "1111," or "1234." If you've changed it and forgotten it, a full reset (Cold Reset) is the only solution. The instructions for this vary for each model and usually involve a complex key combination when turning it on.
