How to reconfigure a printer to a new Wi-Fi network: 5 proven methods

Switching to a new router or changing the Wi-Fi password automatically disconnects the printer from the network. Without proper reconfiguration, the device will stop printing over the air, and attempts to connect via Wi-Fi Direct or cloud services end up with errors. In this article, we'll cover all the current methods for changing the network—from manually entering parameters to using WPS and a temporary USB connection.

We will pay special attention to the nuances for printers without display (For example, Canon PIXMA MG2540S or HP DeskJet 2720), where standard methods often fail. We'll also look at common errors that prevent the printer from "recognizing" the new network, and how to resolve them without a factory reset.

Why doesn't my printer connect to a new Wi-Fi network automatically?

Unlike smartphones or laptops, printers do not support the function automatic reconnection to the network when its parameters are changed. This is due to firmware features and the manufacturers' security policies. Here are the key reasons:

• 🔄 Changing SSID or passwordEven if the network name remains the same, but the password has changed, the printer will lose connection. Devices Epson EcoTank And Brother DCP in this case, they require a complete reconfiguration.
• 📡 Replacing the routerThe new router has a unique MAC address, to which the printer is not attached. Models HP OfficeJet may block connections to "unknown" access points.
• 🔒 Changing the encryption typeTransition from WPA2-PSK on WPA3 (or vice versa) invalidates old network settings. This applies to printers older than 2018.
• ⚡ Resetting the router settingsAfter a hard reset of the router, all connected devices, including the printer, lose access.

Manufacturers deliberately do not implement auto-connection due to security risks. For example, a printer Canon MAXIFY GX6050 may be vulnerable to an evil twin attack if it automatically connects to any network with a known SSIDTherefore, manual tuning remains the only reliable method.

Method 1: Reconnecting via the printer menu (for models with a screen)

If your printer has a touch or button display (e.g. HP Envy 6020, Epson WorkForce WF-2830), the easiest way is to use the built-in menu. This method works for 80% of modern models.

Instructions:

1. Turn on the printer and wait for the main menu to load.
2. Go to the section Settings → Network → Wireless (points can be called Wi-Fi Setup or Wireless LAN).
3. Select an option Setting up a wireless network (Wireless Setup Wizard).
4. The printer will begin scanning for available networks. Find your new printer in the list. SSID and select it.
5. Enter your Wi-Fi password using the on-screen keyboard. For complex passwords (with symbols) !@#$) you may need to switch the layout.
6. Confirm saving the settings. The printer will reboot and attempt to connect.

If the network does not appear in the list, check:

• 📶 Network visibility: Some printers do not show hidden ones SSID (where broadcast is disabled). Enable visibility in the router settings.
• 🔋 Signal strength: The printer should be no further than 5 meters from the router during setup.
• 🔄 Router operating mode: if used 5 GHz, and the printer only supports 2.4 GHz, the network will not be visible.

Make sure the printer is plugged in | Check the ink/toner levels (some models block setup when the level is low) | Disable the VPN on your smartphone/PC if it is used for management | Restart the router 2 minutes before setup -->

⚠️ Attention: Printers Brother series DCP-T425W And DCP-T720DW You may be asked to enter your password twice—first to connect to the network, then to confirm. If you encounter an error after entering it the first time, repeat step 5.

Method 2: Using the WPS button (fastest method)

Technology WPS (Wi-Fi Protected Setup) allows you to connect your printer to the network without entering a password. This method works if:

• 🔘 Your router supports WPS (the button is usually labeled or marked with an icon ).
• 🖨️ The printer is WPS compatible (check the instructions or the sticker on the back of the device).
• ⚙️ WPS is not disabled in the router's security settings.

Step-by-step instructions:

1. Make sure the printer is turned on and in standby mode (not printing or scanning).
2. Press and hold the button Wi-Fi on the printer for 3-5 seconds until the indicator starts flashing blue/green. For Canon PIXMA This is a button with an antenna icon.
3. For 2 minutes press the button WPS on the router. Hold it for 2-3 seconds until the indicator light starts flashing.
4. Wait until the Wi-Fi light on the printer turns solid (usually takes 30-60 seconds).

If connection failed:

• 🔄 Repeat the process, but press WPS on the router first, then activate WPS mode on the printer.
• ⏱️ Please allow 2 minutes for the printer to exit pairing mode.
• 📡 Check that the router is not operating in standby mode WPS Lock (blocked after several unsuccessful attempts).

⚠️ Attention: Some providers (eg. Rostelecom or Beeline) WPS is disabled by default in branded routers. To enable it, go to the router's web interface (192.168.0.1 or 192.168.1.1) and activate the option in the section Wireless Network → WPS.

Method 3: Setup via USB cable (for printers without a display)

Printers without a screen (eg. HP DeskJet 2720, Canon PIXMA MG2540S) do not allow you to enter the Wi-Fi password manually. In this case, a temporary connection via USB will help transfer network settings from a computer.

What you will need:

• 🖥️ A computer with Windows/macOS (laptop or PC).
• 🔌 USB cable (usually included with the printer).
• 📀 Software disc or downloaded drivers from the manufacturer's official website.

Step-by-step instructions for Windows:

1. Connect the printer to your computer using a USB cable. Turn on the printer.
2. Install the drivers if they are not installed automatically. For HP download HP Smart, For Canon — Canon PRINT Utility.
3. Launch the printer management program (for example, HP Printer Assistant or Epson Software Updater).
4. Go to the network settings section. HP Smart This Printer → Settings → Wireless Network.
5. Select your Wi-Fi network from the list and enter the password. Click Apply.
6. Disconnect the USB cable. The printer will reboot and connect to Wi-Fi.

For macOS:

1. Connect the printer via USB and add it to System Preferences → Printers & Scanners.
2. Open Printer utilities (For Epson) or Canon IJ Network Tool.
3. In the section Network setup select Wireless communication and follow the wizard's instructions.

Method 4: Printer Web Interface (for advanced users)

Many network printers (eg. HP LaserJet Pro, Xerox WorkCentre) have a built-in web server. This allows you to change Wi-Fi settings even if the device is temporarily connected to a computer via a cable.

How to access:

1. Connect the printer to the router via Ethernet cable (or temporarily return to the old Wi-Fi settings).
2. Find IP address printer:
   • Print Network report (usually a button Information or a combination Hold down the Wi-Fi button).
   • Check the list of devices in the router's web interface (192.168.0.1).

Enter the printer's IP address into your browser's address bar (e.g. 192.168.0.105).

Log in (default logins: admin/admin, admin/blank password, or see instructions).

Go to the section Network → Wireless → Wireless Setup.

Select a new network, enter the password and save the settings.

Example interface for HP LaserJet Pro M426fdw:

Menu: Network → Wireless (802.11) → Wireless Setup Wizard
Fields to fill in:
- SSID: [your_network_name]
- Security: WPA2-PSK (recommended)
- Passphrase: [your_password]

⚠️ AttentionAfter changing the settings, the printer may freeze for 1-2 minutes. Do not unplug the cable or turn off the power—wait for the printer to reboot automatically. If the Wi-Fi indicator does not light up after 5 minutes, reset the network using the printer menu (Reset network settings).

What to do if you don't know the printer's IP address?

If your printer does not print a network report and does not appear in the router's device list, try:

1. Connect it via USB and use the manufacturer's program to scan the network (for example, HP Print and Scan Doctor).

2. Temporarily connect to another network (for example, from a phone in access point mode) and print the report.

3. For printers Epson hold the button Wi-Fi 10 seconds - this activates the mode AP Mode (the printer will create its own network with the name DIRECT-xx-Epson). Connect to it from your computer and open http://epsonnet.local.

Method 5: Reset the printer to factory settings

If none of the methods worked, there remains full resetThis will delete all saved networks, but return the printer to its original state. Use this method only as a last resort!

How to reset settings:

• 🔄 Software reset:
  1. Go to the printer menu: Settings → System → Reset settings.
  2. Select Reset network settings (not a full reset!).
  3. Confirm the action. The printer will reboot.

🔧 Hard reset (if the menu is not available):

1. Turn off the printer.
2. Press and hold the button Cancel (or Reset, if any) and hold it.
3. Turn on the printer without releasing the button for 10-15 seconds.
4. Release the button when the indicators start flashing randomly.

After reset:

1. The printer will create its own network (for example, HP-Print-xx-Setup or CANON-IJ-SETUP).
2. Connect to it from your phone or computer.
3. Open your browser and go to the address given in the instructions (usually http://setup.printer.com or 192.168.223.1).
4. Follow the setup wizard to connect to your new Wi-Fi.

Common mistakes and their solutions

Even with proper setup, your printer may not connect to Wi-Fi. Here are the most common issues and how to fix them:

If the printer still does not connect, check:

• 🔌 Router power supply: some models (eg TP-Link Archer C6) may block new devices when overheated.
• 📡 Wi-Fi channel: if a channel is selected in the router 12–14, and the printer only supports 1–11, connection will be impossible.
• 🔄 Network operating mode: turn off 802.11r (Fast Transition) - It is not compatible with many printers.

⚠️ Attention: Printers Samsung (For example, Samsung Xpress M2020W) may conflict with routers ASUS due to the specifics of the protocol implementation WMMIn this case, turn it off. WMM in the router settings or update the printer firmware.
