Changing internet providers or installing a new router often leaves users with the reality that their office equipment has stopped responding to print commands. Network settings Storage devices are tightly bound to the previous router's settings, and automatic reconnection doesn't always occur. In this situation, you need to manually update the configuration. printerso that he could again accept missions by air.
The process of restoring the connection depends on the model of your equipment and whether it has a display. Modern MFP (multifunctional devices) often have touchscreens that make the task easier, while budget models require the use of a USB cable or buttons on the case. Understanding the operating principle IP addressing on the local network will help you quickly understand the causes of the failure.
Below, we'll detail all available methods, from the simplest click of a button to a complete driver reinstallation. Be prepared to require physical access to the router and the printer itself.
Equipment preparation and compatibility testing
Before you begin any active steps, you need to make sure that your new network environment is ready to receive devices. New router must be fully configured, have an active internet connection, and broadcast a signal in the bands supported by your equipment. Many older printers operate exclusively in the band 2.4 GHz and don't see the network 5 GHz.
Make sure you know the exact name of the new network (SSID) and its password. When you change routers, these settings often change, especially if you didn't transfer the settings from your old device. Also, check if the feature is enabled. WPS on the router, as this is the fastest pairing method.
- 📶 Make sure that the new router broadcasts a signal in the 2.4 GHz range if the printer is old.
- 🔑 Write down your Wi-Fi password correctly, respecting the case of the characters.
- 🔌 Prepare the USB cable (type AB) that came with the device.
- 💻 Install the latest drivers on your computer from the manufacturer's official website.
⚠️ Note: If your new router uses WPA3 security, older printers may not connect. Temporarily switch the encryption type to WPA2/WPA Mixed in the router settings.
WPS method: quick connection without password
Technology Wi-Fi Protected Setup (WPS) allows you to connect devices to a network without entering long passwords. This method is ideal if the printer doesn't have a screen or keyboard for entering characters. The algorithm is simple: you activate search mode on the router, then start a network search on the printer.
Find the button on the router body. WPSIt can be a separate button or combined with the Wi-Fi power button. Press and hold it for 2-3 seconds until the WPS indicator starts blinking. This means the router is open to new devices for a short period of time.
Now go to your printer. If it has a screen, find the section in the menu Network or Wireless and select the item WPS Push ButtonIf there's no screen, you often need to press and hold the wireless button on the printer until the indicator light starts blinking. The devices will find each other automatically.
The process takes no more than two minutes. Once the connection is successful, the Wi-Fi indicator on the printer will stop flashing and turn solid. This indicates that IP address received and connection with the router established.
Using a USB cable for initial setup
If automatic methods fail, the most reliable method is to use a cable. The computer acts as an intermediary, transmitting network credentials (login information) from the new router directly to the printer's memory. To do this, you'll need to install the full software from a disc or the manufacturer's website.
Run the driver installer and select "Connect the device wirelessly." The program will ask you to connect the printer to your computer via USB cableDon't skip this step, even if you're aiming for wireless printing. The cable is required for the initial configuration of the device's network card.
During installation, the program will detect a new Wi-Fi network. You'll be prompted to select your network from the list and enter the password. After confirming the settings, the program will transfer them to the printer. At a certain point, the installer will ask you to disconnect the USB cable—do so to complete the transition to wireless mode.
☑️ USB Setup Checklist
This method is good because it eliminates manual input errors and ensures that all the necessary components for network operation are installed. Network port will be configured correctly, and the computer will immediately create a print queue.
Setting up via the printer control panel
Mid- and high-end models feature color displays and a full menu. In this case, a computer or cable may not be needed at all. All operations are performed directly on the device via the interface. Embedded Web Server or built-in menu.
Using the navigation buttons or touchscreen, navigate to the Settings section. The icon may look like a gear or an antenna. Find the item Wireless Setup Wizard (Wireless Setup Wizard). The printer will begin scanning the air and display a list of available networks.
Select a name for your new router from the list. If the network is hidden, select the option to enter a name manually. A password keyboard will then appear on the screen. Be careful when entering the password, as it's easy to make capitalization errors or mix up similar letters on small screens.
| Device type | Menu path (approximate) | Nuance |
|---|---|---|
| HP LaserJet | Settings -> Network -> Wireless Network | PIN confirmation required |
| Canon PIXMA | Menu -> LAN settings -> Wireless LAN setup | You need to select "Other" |
| Epson EcoTank | Wi-Fi -> Wi-Fi Setup Wizard | Supports WPS and manual input |
| Brother | Menu -> Network -> WLAN -> Setup Wizard | Selecting an infrastructure mode |
After entering the data, the printer will attempt to connect. A successful connection is confirmed by printing a report sheet or by the "Connected" message on the screen. Now TCP/IP protocol configured and the device is ready to use.
Mobile applications and cloud services
The modern printing ecosystem is often tied to mobile apps. Manufacturers release utilities for iOS and Android that allow you to configure your printer to a new Wi-Fi network directly from your smartphone. This is especially convenient if you don't have a computer with a USB port or a driver disc handy.
Download the official app (for example, HP Smart, Canon PRINT, Epson iPrint). Start the process of adding a new device. The app will ask you to temporarily switch to Wi-Fi Direct, which is provided by the printer itself, or connect to it via Bluetooth.
Once direct contact is established, the app will transmit your primary home network settings to the printer. The smartphone acts as a bridge, transmitting the settings from the router to the printer. This is a modern standard. IoT (Internet of Things), making life easier for usersp>
In addition, many devices support Wi-Fi DirectIn this mode, the printer creates its own network. You can connect to it from a smartphone or laptop and print even without access to the main router, although the internet connection on the printer will not work in this mode.
⚠️ Important: When using mobile apps, ensure your smartphone and printer are on the same subnet. If you have "Guest Wi-Fi" configured, the devices may not be able to see each other due to client isolation.
Resolving IP address issues and conflicts
Even after successful setup, situations may arise where the computer does not "see" the printer on the network. Often the problem lies in the fact that DHCP server The router assigned the device a new IP address, different from the one specified in the driver on the computer.
In Windows or macOS, you need to delete the old printer instance and add it again. The system will find the device at the new address on the local network. It's also worth checking your firewall and antivirus software, as they may be blocking printing ports.
- 🔄 Reboot your router and printer at the same time to renew the IP lease.
- 🖥️ Delete old print queues in the OS control panel.
- 🛡️ Check if your firewall is blocking port 9100 (the standard printing port).
- 📡 Make sure your computer and printer are connected to the same network (not a guest network).
If the printer is statically assigned to a specific IP address in the router, make sure this assignment (Reservation) is also updated or reset after changing the hardware. Address conflicts are a common cause of equipment disappearing after a network upgrade.
Can a printer be connected to 5GHz Wi-Fi?
Most older and budget printer models only support the 802.11 b/g/n standard, which operates in the 2.4 GHz band. They won't physically detect a 5 GHz network. Modern, expensive models can support dual-band mode, but for stability, 2.4 GHz is better because it has better wall penetration, which is important for a printer often placed in a corner.
What to do if you forgot your Wi-Fi password?
If you've changed your router and don't remember the password, you can find it in the router's web interface. Connect to it via cable or Wi-Fi, enter the gateway address (usually 192.168.0.1) in your browser, and access the settings. The password will be listed in the Wireless Security section. The password is also often written on a sticker on the bottom of the router if you haven't changed the factory settings.
Do I need to reinstall drivers when changing Wi-Fi?
Not always. If you've simply changed the password or network name but the printer's IP address remains the same (static IP), the drivers may continue to work. However, in 90% of cases, changing the router also changes the addressing scheme, so creating a new print port or completely reinstalling the driver is the most reliable solution.
