How to Reconnect Wireless Printer After Changing Wi-Fi Password: A Complete Guide

Introduction

Reconnect wireless printer after changing your WiFi password is a common challenge many face when updating their home network security. When you change your Wi-Fi password, all your previously connected devices lose their connection—including your printer. This disconnection can be frustrating, especially when you need to print important documents urgently. This comprehensive guide will walk you through the process of reconnecting your wireless printer to your network after a password change, ensuring you can resume printing with minimal downtime. Whether you use HP, Canon, Epson, or any other major printer brand, these strategies will help you quickly reestablish your connection and troubleshoot any issues that arise.

What Is Wireless Printer Connection?

A wireless printer connection allows your printer to communicate with your computer, smartphone, or tablet without physical cables. Instead, it uses your home’s Wi-Fi network as the bridge between devices. This connection works by having both your printer and other devices connected to the same wireless network, enabling them to find and communicate with each other.

When you change your Wi-Fi password, this connection breaks because your printer still tries to connect using the old password it has stored in memory. To restore functionality, you need to update the stored network credentials in your printer’s settings. Different printer models store this information in various ways, but all wireless printers have some method for updating network settings.

Understanding this wireless connection concept is crucial because it helps explain why simply changing your router password affects your printer and why reconfiguration is necessary. Modern printers often have built-in web interfaces or dedicated apps that make this reconfiguration process much simpler than in older models.

7 Steps to Reconnect Your Wireless Printer After Changing WiFi Password

Step 1: Gather Your Network Information

Before attempting to reconnect your printer, make sure you have all the necessary information ready:

• Your new Wi-Fi network name (SSID)
• Your new Wi-Fi password
• Your printer’s make and model
• Your router’s location (ensure it’s functioning properly)

Having this information ready will streamline the reconnection process and prevent frustration from incomplete preparation. For enhanced security, verify that your new Wi-Fi password follows strong password practices with a mix of uppercase and lowercase letters, numbers, and special characters.

Step 2: Access Your Printer’s Control Panel

Most modern wireless printers have a built-in display screen with network settings. To access these settings:

• Turn on your printer and wait for it to fully boot up
• Navigate to the “Settings,” “Setup,” or “Network” menu using the printer’s control panel buttons
• Look for “Wireless Setup,” “Wi-Fi Setup,” or “Network Configuration” options

For printers without a display panel, check if there’s a dedicated wireless button that, when pressed, initiates the setup mode. Some printers might require you to press and hold combinations of buttons to enter network configuration mode. Consult your printer’s manual if you’re unsure which buttons to press.

Step 3: Select Your Wi-Fi Network

Once in the network settings menu:

• Choose “Wireless Setup Wizard” or similar option
• The printer will scan for available networks
• Select your Wi-Fi network name (SSID) from the list
• Enter your new password using the control panel interface
• Confirm and apply the settings

Some printers display a message confirming successful connection, while others might show signal strength bars to indicate connection quality. If your network doesn’t appear in the list, ensure you’re within range of your router and that the router isn’t hiding its SSID.

Step 4: Use WPS (Wi-Fi Protected Setup) If Available

For quicker setup, many modern routers and printers support WPS:

• Press the WPS button on your router
• Within 2 minutes, press the WPS button on your printer or select the WPS option from the printer’s menu
• Wait for the connection to establish automatically

This method bypasses manual password entry and is especially useful for printers with limited input options. However, WPS must be enabled on your router for this method to work, and security experts often recommend disabling WPS as it can potentially be exploited in some router models.

Step 5: Use Printer Software on Your Computer

If direct configuration is challenging, try reconnecting through your computer:

• Install or open your printer’s software/app on your computer
• Navigate to “Printer Setup,” “Maintenance,” or “Tools” section
• Look for “Change Network Settings” or “Wireless Setup”
• Follow the on-screen instructions to update the Wi-Fi information

This method often provides a more user-friendly interface than the printer’s built-in display. Many printer manufacturers offer dedicated applications that can detect when your printer is offline and guide you through the reconnection process with intuitive wizards.

Step 6: Use Printer Mobile Apps

Most major printer brands offer mobile apps for network management:

• Download your printer manufacturer’s app on your smartphone
• Open the app and select your printer model
• Follow the guided setup process to update Wi-Fi settings

These apps often provide the simplest interface for managing network settings. They can detect nearby printers even when they’re not connected to your network, making them ideal for reconfiguration after password changes.

Step 7: Verify the Connection

After completing the setup:

• Print a network configuration page from your printer’s menu to confirm connection details
• Try printing a test page from your computer or mobile device
• Check that the printer appears in your devices’ printer lists

The network configuration page typically shows the IP address assigned to your printer, signal strength, and connection status—all valuable information that confirms your printer is properly reconnected to your network.

Additional Tools and Solutions for Printer Connectivity

Printer Configuration Web Interface

Many modern wireless printers have built-in web servers that allow configuration through a browser:

1. Print a network configuration page to find your printer’s IP address
2. Enter the IP address in your web browser
3. Log in using the admin credentials (often printed in the manual)
4. Navigate to “Network,” “Wireless,” or “Wi-Fi” settings
5. Update your network credentials

This method provides access to advanced settings that might not be available through the printer’s control panel. Web interfaces typically offer more detailed configuration options, including static IP assignment, proxy settings, and wireless security protocol selection.

Printer Reset Options

If reconfiguration attempts fail, consider a partial reset:

• Look for a “Network Reset” or “Restore Network Defaults” option in your printer’s menu
• This keeps your other settings intact while clearing network configurations
• After resetting, follow the initial setup process to connect to your new network

As a last resort, a factory reset might be necessary, though this will remove all customized settings. Before performing a factory reset, note any special configurations you’ve made to restore them afterward.

Troubleshooting Common Wireless Printer Reconnection Problems

Printer Can’t Find Network

If your printer can’t detect your Wi-Fi network:

• Ensure your printer is within range of your router
