@J242, Welcome to HP Support Community. 

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

I understand how important it is to get your HP LaserJet M140we connected to Wi-Fi, especially when you have urgent documents to print. Let’s walk through some steps to resolve the "Invalid Password" issue you're encountering.

Double-Check Wi-Fi Password

• Ensure you're entering the exact Wi-Fi password, including correct capitalization and special characters.
• Try connecting another device (like a phone or laptop) to the same Wi-Fi using the same password to confirm it works.

Reset the Printer’s Network Settings

This clears any saved Wi-Fi credentials and lets you start fresh:

• Press and hold the Wireless button on the printer until the Attention light blinks.
• The printer will restart and reset its network settings.

Reconnect Using HP Smart App

Use the HP Smart app to set up the printer again:

1. Download or open the HP Smart app on your phone:
   HP Smart
2. Make sure your phone is connected to the same Wi-Fi network you want the printer to use.
3. Open the app and tap “+” to add a new printer.
4. Follow the on-screen instructions to connect the printer to Wi-Fi.

Use WPS (If Supported by Your Router)

If your router supports WPS (Wi-Fi Protected Setup):

• Press the WPS button on your router.
• Within 2 minutes, press and hold the Wireless button on the printer until it starts blinking.
• The printer should automatically connect to the Wi-Fi.

Check for Firmware Updates

Sometimes, a firmware update can resolve connectivity issues:

• In the HP Smart app, go to Printer Settings > Advanced Settings > Tools > Printer Updates.

I hope this helps. 

Take care and have a good day.
