[lisaD21]

I changed my internet password, and now my LaserJet will not connect. I have tried re starting all devices, and I have tried deleting my printer from the HP  Smart app, but it didn't help. I followed the steps given in trouble shooting and with virtual assistant, but that didn't work either. anyone have any suggestions?

Hi @lisaD21,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If your HP LaserJet M234sdw is having trouble reconnecting to the internet after a password change, follow these steps to troubleshoot and resolve the issue:

1. Reconnect to Wi-Fi Network

• On the printer’s control panel, go to the Wireless or Network menu. This is usually found under Setup or Settings.
• Choose Wireless Setup Wizard or a similar option to search for available networks.
• Find and select your Wi-Fi network from the list.
• Enter the new Wi-Fi password. Make sure it's entered correctly, paying attention to capitalization and special characters.
• Confirm the settings and wait for the printer to connect to the network. This might take a few moments.

2. Reset Network Settings

• On the control panel, go to Setup > Network > Restore Network Settings or a similar option.
• After resetting, restart the printer to complete the reset process.
• Follow the steps in Reconnect to Wi-Fi Network to reconnect using the new password.

3. Update Printer Firmware

• Go to the HP website and check for any available firmware updates for your printer model.:
• Follow the instructions provided on HP’s website to download and install any updates.

4. Use the HP Smart App

• Open the HP Smart app on your device. Go to Printers and select Add Printer.
• The app will guide you through the setup process. Follow the instructions to reconnect the printer to your network.
• Ensure the app recognizes your printer and that it shows as connected.

5. Check Network and Router Settings

• Make sure your router is functioning correctly and that other devices can connect to the internet.
• Restart your router to resolve any connectivity issues.
• Ensure that your router’s security settings (WPA/WPA2) are compatible with your printer.

6. Check Printer IP Address

• Print a network configuration page from the printer’s control panel to check the current IP address and connection status.
• If the printer has an IP address but is still not connecting, try accessing the printer’s web interface by entering the IP address into a web browser on your computer.
• Ensure that network settings are correct and adjust if needed.

7. Reset Printer

• If all else fails, you can perform a factory reset on the printer. Refer to the printer’s manual for instructions on how to perform a factory reset.
• After resetting, go through the initial setup process to reconnect the printer to your Wi-Fi network.

I hope this helps.

Take care and have a good day.
