Changing internet service providers or buying a new router is always stressful, but the real headache begins when you try to print a document and your computer says the printer is unavailable. This happens because the printer has lost its connection to the network, and the network name or password has changed. The old settings stored in the printer's memory are no longer valid, and now you have to do the small but important job of updating them.
There's no need to panic or search for a USB cable if you have a modern model with wireless support. Reconnecting usually takes 5 to 15 minutes if you know the correct steps. In this article, we'll break down the universal algorithms for most popular brands and explain why. easy to turn on and off technology does not always help in this case.
The most important thing you need to prepare before you begin is the exact name of your new WiFi network and its current password. Also, make sure your router is turned on and providing a signal. If you're using a dual-band router, remember that older printers often require a network frequency of 2.4 GHz, not 5 GHz, although modern devices can operate in both ranges.
The first step should always be a full reboot of the entire hardware chain. This clears temporary errors and clears the cache of network modules. Turn off the router, turn off the printer, and wait about 30 seconds before turning them back on in a specific sequence: first the router, wait until it fully boots up, and only then turn on the printer.
⚠️ Note: If your router is broadcasting two networks with the same name (Smart Connect), some older printer models may not see the network or connect to it. In this case, it's best to temporarily separate the networks in your router settings or ensure you're connecting to the 2.4 GHz band.
Resetting the printer's network settings
Before attempting to "introduce" the printer to a new router, you need to erase old data from its memory. Each manufacturer may have a different name for this procedure, but the essence is the same: restore network settings by default. If this is not done, the device may continue to search for the old access point, ignoring the new one.
On devices with a display, the menu is usually located in the settings section marked with a gear or antenna icon. Find "Network," "Wi-Fi Settings," or "Wireless." Within this menu, look for the option "Restore," "Reset Network Settings," or "Clear Settings." Confirm the action, and the connection indicators should start flashing, indicating they're ready to search.
For models without a display, the procedure is often performed using a button combination. For example, on many MFPs HP or Canon You need to simultaneously press and hold the wireless button and the cancel button for 3-5 seconds until the indicators flash alternately. On the equipment Epson Sometimes you need to hold the WiFi button until the network indicator lights up. It's best to check the manual for the exact combination, as it varies by model.
Why do you need to reset network settings?
A reset removes not only the network name and password, but also static IP addresses, proxy settings, and port configurations that may conflict with the new router. This provides a clean slate for starting configuration.
Connecting via WPS (the fastest way)
If your router and printer support the technology WPS (Wi-Fi Protected Setup), the connection process takes just a couple of minutes without entering a password. This is ideal for those who are worried about making mistakes when entering complex characters or don't want to search for instructions for push-button models.
First, locate the WPS button on the router. It may be separate or combined with the WiFi power button. Press it once (sometimes you need to hold it for 2-3 seconds) until the WPS indicator starts blinking. Now you have about two minutes to activate the printer's search mode.
On the printer, find a button with an antenna or WiFi icon. Press and hold it until the wireless indicator light starts blinking. If your device has a display, select "Settings" → "WiFi" → "WPS" → "Push Button" from the menu. Once the devices have found each other, the indicators will stop blinking and turn solid, indicating a successful connection.
⚠️ Important: WPS technology only works for a short time after you press the button on the router (usually 2 minutes). If you don't activate the mode on the printer in time, you'll have to repeat the process again because the router's security timer will expire.
Setting up via the control panel (for models with a screen)
Modern MFPs from Brother, HP And Canon They are equipped with color touchscreens, making the process much easier. You don't need any cables or additional software; everything is done directly on the device. This method is the most reliable, as you immediately see a list of available networks.
Access the settings menu by tapping the gear icon or "Setup." Find the network-related section. It may be called "Network," "Wireless," or "Network Settings." Select "Wireless Setup Wizard." The printer will begin scanning the air and, after a few seconds, display a list of available WiFi networks.
Find the name of your new network in the list and click on it. If the network is hidden, select the "Enter name manually" option. A keyboard will then appear on the screen, where you will need to enter the password. Be careful: letter case is important, and symbols like 0 (zero) and O (letter) is easy to confuse. After entering, confirm the action, and the printer will attempt to connect.
- 📶 Make sure you select a 2.4 GHz network if your printer is older and does not support the 5 GHz standard.
- 🔑 Check your language layout when entering your password to avoid entering unnecessary characters.
- 🔄 If the connection fails the first time, try deleting the saved network profile and creating a new one.
☑️ On-screen setup checklist
Using a USB cable for initial setup
If wireless methods don't work or the printer can't see the network, a good old USB cable can help. This method is often called "wired WiFi setup." It allows the computer to transmit the new network information to the printer directly, bypassing complicated button manipulation.
To do this, you'll need the installation disc that came with the printer or the full package of drivers and utilities downloaded from the manufacturer's website. Run the software installation and select the "Wireless" or "Wi-Fi" connection type. When prompted to connect the device, connect the printer and computer with a USB cable.
The utility will automatically detect the printer and offer to transfer the WiFi settings your computer is currently using. This is very convenient, as you don't need to enter the password manually—the system retrieves it from your active Windows or macOS connections. Once the data has been transferred, you can disconnect the cable.
It's important to note that this method requires administrator rights on your computer. Also, make sure the cable is in good condition: some cables are designed only for charging and don't transfer data. Use a high-quality cable like A-B (standard printer).
⚠️ Warning: When setting up via USB, your antivirus or Windows Firewall may block the transfer of network parameters. If the process freezes, try temporarily disabling protection or adding an exception for the driver installer.
Configuration via the manufacturer's mobile app
In the era of smartphones, manufacturers are actively promoting their ecosystems. Applications HP Smart, Epson iPrint, Canon PRINT Inkjet/SELPHY or Brother iPrint&Scan Allows you to set up your printer in just a few taps. This is especially useful if you don't have a computer with a disc drive or USB ports nearby.
First, make sure your smartphone is connected to the WiFi network you want to connect the printer to. Download the official app from the App Store or Google Play. Launch it and tap the "Add a new device" button (usually a "plus" or "Add printer").
The app will find the printer in setup mode (when it's blinking after a reset) and prompt you to transfer the WiFi passwords. In some cases, you'll need to scan the QR code on the printer or enter the PIN displayed on its screen. Your smartphone will automatically transfer all the necessary data in the background.
- 📱 Make sure Bluetooth is enabled on your smartphone – it is often used for initial device detection.
- 🔒 Allow the app to access geolocation, as Android requires this to scan for WiFi networks.
- 🆔 Make sure your phone and printer are on the same subnet (do not use a guest WiFi network for setup).

Solving common problems and errors
Even if you follow the instructions correctly, errors may occur. The computer may not see the printer, or the device's status may be "Offline." Often, the problem lies in an old driver with an invalid IP address remaining on the computer. You need to remove the device from the list of printers in the system and add it again.
Another common cause is client isolation in your router settings. This feature prevents devices on the network from seeing each other. Access your router settings (usually in a browser at 192.168.0.1 or 192.168.1.1) and ensure this option is disabled for your home network.
If your printer is connected but not printing, try assigning it a static IP address. This can be done through the printer's web interface (enter its IP address in a browser) or through the router's DHCP settings. A fixed address will prevent connection loss after the router reboots.
⚠️ Note: Router interfaces and printer firmware are constantly being updated. The location of menu items may differ from that described. If you cannot find the desired setting, check the latest documentation on the official website of your equipment manufacturer.
What to do if nothing helps?
Try temporarily disabling NAT prototyping or the firewall on your router for diagnostic purposes. A full factory reset and reconfiguration of the router from scratch also helps, as this often resolves hidden addressing conflicts.
Frequently Asked Questions (FAQ)
Do I need to reinstall drivers after changing my router?
In most cases, reinstalling drivers isn't necessary; simply updating the connection port in the printer properties or re-adding the device through "Devices and Printers" is sufficient. However, if the printer is very old or the new router uses a different security standard (for example, WPA3 instead of WPA2), updating the printer firmware or driver may be necessary.
The printer sees the network, but says "Unable to connect." What's wrong?
Most often, the cause is an incorrectly entered password or incompatible encryption standards. Check that you're not using special characters in your password that the printer might not recognize correctly. Also, try temporarily simplifying your password (letters and numbers only) to test it.
Can I connect a printer to a guest WiFi network?
Technically, this is possible, but not recommended. Guest networks often have client isolation, preventing the computer from printing. Furthermore, such networks may block ports required for scanner operation over the network.
How to find out the printer's IP address after connection?
On devices with a display, the IP address is displayed in the "Network Report" or "Wi-Fi Status" section. On models without a display, you can print a network configuration report by quickly pressing the information (i) button or a key combination (usually the WiFi button + Cancel button). The IP address can also be found in the client list in the router settings.
