Changing internet providers or purchasing a more powerful router inevitably requires reconfiguring the entire home network. Printers and multifunction devices are often the most challenging part of this chain, as they lack a password entry screen and rely on a stable connection.
You'll need to complete several steps to get your device working again. The process may vary depending on the brand, but the basic steps are the same for most modern models.
Preparing equipment and resetting old settings
Before starting the procedure, make sure that the new router is fully configured and distributing the Internet. Old network profiles The printer's settings may conflict with the new parameters, causing connection errors. If you simply changed the password but the network name (SSID) remains the same, the device may attempt to connect automatically, but this doesn't always work.
In most cases, a forced reset of the network settings is required. This will return the Wi-Fi module to its original state, ready to search for a new router. Ignoring this step often results in the printer being stuck in the "Disconnected" or "Offline" status in the computer's operating system.
To reset, use the device's control panel. Look for a button with a wireless network icon or arrows. Pressing and holding this button for 5-10 seconds usually initiates the memory clearing process. On some models HP or Canon Requires simultaneous pressing of the Wi-Fi button and the cancel button.
After the reset, the wireless indicator will begin flashing, indicating it's ready to pair. If the flashing stops but the connection isn't established, try turning the device off and on again.
Using WPS technology for fast synchronization
The easiest way to reconfigure a printer to another Wi-Fi network without entering a password from the computer keyboard is to use technology WPS (Wi-Fi Protected Setup). This method works if your router supports this feature and has a physical button or a software switch in the web interface.
The process is extremely simple: press the WPS button on the router, after which you have about two minutes to activate the same function on the printer. The device will automatically exchange encryption keys and connect to the network.
- 📡 Press the WPS button on the router (the indicator should blink).
- 🖨️ On the printer, press and hold the wireless button until the indicator light starts blinking.
- ⏳ Wait until the Wi-Fi indicator on the printer lights up solid.
- ✅ Check your connection status by printing a network configuration report.
It's worth keeping in mind that some modern routers, especially those provided by ISPs, may have WPS disabled by default for security reasons. In this case, you'll need to use manual configuration via a computer or mobile app.
Why might WPS not work?
WPS technology is considered vulnerable, so some router manufacturers (for example, ASUS or TP-Link in new firmware) may hide this feature or require its activation through the web interface in the Wireless -> WPS section.
Setup via a computer using a USB cable
If wireless methods fail, a classic solution is to use a USB cable. This method allows you to transfer network parameters (SSID and password) directly from your computer to the printer. You'll need the original cable that came with the printer or a high-quality replacement with ferrite cores.
Connect the printer to your PC using a cable and run the installation disk or download the full driver package from the manufacturer's official website. During the installation, select the "Wireless" or "Wi-Fi" connection type, even though the device will be physically connected via a wire.
☑️ Preparing for wired setup
The installer will prompt you to change the connection type from USB to wireless. At this point, the program will automatically transfer the router settings to the printer's memory. Once the transfer is successful, the system will prompt you to disconnect the cable. It's important not to interrupt the process until the appropriate message appears on the monitor screen.
This method is especially useful for older models that don't support automatic network detection in the new frequency range. The computer acts as a bridge, broadcasting the correct security parameters.
Using mobile apps to manage your network
Modern manufacturers actively promote the use of smartphones for initial setup. Apps like HP Smart, Epson iPrint or Canon PRINT They can read the parameters of the Wi-Fi network to which the phone is connected and transfer them to the printer.
To do this, your smartphone must be connected to the new router. Launch the app and select "Add Printer" or "Set Up New Device." The app will ask you to temporarily connect to the printer's Direct network, after which it will automatically return you to the main network and transfer data.
⚠️ Important: Make sure location and Bluetooth are enabled on your smartphone. On modern versions of Android and iOS, these permissions are required for apps to scan the surrounding air and detect the printer in setup mode.
The advantage of the mobile method is the protocol support Wi-Fi DirectEven if the printer isn't yet online, the phone can connect directly to it to transfer the configuration. This eliminates the need to find a USB cable or drag a computer to the MFP's location.
However, if your router uses split-band (separate networks for 2.4 GHz and 5 GHz with the same name), the app may fail. In such cases, it's recommended to temporarily split the networks in your router settings, connect to the 2.4 GHz band, set up the printer, and then merge them back together.
Troubleshooting 2.4GHz and 5GHz Bandwidth Issues
One of the most common reasons why a printer doesn't recognize a new router is frequency band incompatibility. Most office and home printers operate exclusively in the 2.4 GHz, which has a longer range but lower speed.
New routers often combine the 2.4 GHz and 5 GHz bands under a single name by default (Band Steering technology). A printer may become "lost" when attempting to connect to a high-speed channel it doesn't physically support or when receiving an incorrect response from the router.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Printer compatibility | Full (basic standard) | Only new models |
| Signal range | High (breaks through walls) | Low (fades quickly) |
| Transfer speed | Up to 150-300 Mbps | Up to 1 Gbps and higher |
| Airtime congestion | High (a lot of interference) | Low (clear channel) |
To resolve this issue, access your router settings (usually at 192.168.0.1 or 192.168.1.1). Find the wireless network section and temporarily disable the "Smart Connect" feature or give different frequencies unique names, such as Home_WiFi_2G And Home_WiFi_5G.
Connect your computer or phone to the 2.4 GHz network and repeat the printer setup process. After a successful connection, you can reset your router settings to their default values, although for older devices, separating networks is often a more stable solution.
Assigning a static IP address for stability
After you've successfully reconfigured your printer to a new Wi-Fi network, you may experience a situation where your computer periodically loses the device. This happens because the router may assign a new Wi-Fi network to the printer each time it reconnects. IP address from the DHCP pool.
The computer remembers the old address and continues to try it without receiving a response. To avoid this, it's recommended to assign a permanent IP address to the printer. This can be done in two ways: through the router settings (binding by MAC address) or directly in the printer menu.
The second option is more reliable if you frequently change routers. Go to the printer menu, select "Network Settings" -> "TCP/IP." Disable automatic IP (DHCP) acquisition and enter the address manually, for example, 192.168.1.150The main thing is that this address is not in the range that the router automatically distributes to other devices.
⚠️ Important: When manually entering an IP address, make sure the gateway matches your router's address. If you enter an incorrect gateway, the printer will connect to the local network but will not respond to external requests or scan to the network.
A static address also simplifies installing drivers on other computers in the office or at home. You won't have to search for the device again each time—just specify the saved IP address when adding a new printer to the system.
Common mistakes and how to fix them
Even if you follow all the instructions, specific errors may still occur. Often, the problem lies not with the printer itself, but with the security settings of the new router. For example, if MAC address filtering is enabled, the new device will be blocked even if the password is entered correctly.
It's also worth checking the encryption type. Older printer models may not support the modern standard. WPA3If your router is configured for WPA3 only, the printer simply won't see the network or will return an authorization error. Switch the security mode to mixed (WPA2/WPA3) or temporarily to WPA2.
- 🔥 Driver error: Remove the old device from the printer list in Windows/macOS before installing the new one.
- 🔥 Firewall: Your antivirus or firewall may be blocking printing ports (usually port 9100). Add the device to the exceptions list.
- 🔥 Double NAT: If there's another router behind the main one, the printer may be on a different subnet. Configure the second router as an access point (AP).
If all else fails, perform a full reset of the router's network settings to factory defaults (not to be confused with a full firmware reset) and reconfigure it, paying attention to compatibility with your old equipment.
Is it possible to set up a printer without a computer, just from a phone?
Yes, this is possible for most modern models. Download the manufacturer's official app (HP Smart, Epson iPrint, Brother iPrint&Scan). Connect your phone to the new Wi-Fi network, launch the app, and follow the instructions. Your phone will transfer the network settings to the printer via Bluetooth or a temporary direct connection.
What should I do if the printer sees the network, but says "Not connected"?
Most likely, you entered the wrong password or are using an unsupported encryption type. Check if MAC address filtering is enabled on your router. Also, try disabling the "Guest Network" feature on your router—printers often fail to work in isolated guest segments.
Do printer settings get reset when there is a power outage?
No, network settings (SSID, password, static IP) are stored in the device's non-volatile memory. However, if the router changes the DHCP range or network name, the printer may stop connecting automatically, requiring reconfiguration.
How to find out the printer's IP address after connection?
On the printer itself, press the "Information" button (often marked with an "i" or a leaf icon) or hold down the wireless button. The device will print a report showing the current IP address in the IPv4 Address line.
