@RikVed, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
Here’s a step-by-step guide to help resolve the issue with your HP LaserJet MFP M140w Printer not connecting after upgrading your modem:

Step 1: Reset the Printer’s Network Settings

This clears old Wi-Fi settings and prepares the printer for a fresh setup.

1. Turn on the printer.
2. Press and hold the Wireless button (📶) and the Cancel button (❌) together for 5 seconds.
3. The printer will restart and the wireless light will start blinking, this means it’s in setup mode.

Step 2: Reconnect the Printer to Wi-Fi

Use the HP Smart App (recommended method):

Download or open the HP Smart app on your PC or smartphone: HP Smart
 

Open the app and click “Set up a new printer.”

Follow the on-screen instructions to:

• Detect the printer in setup mode.
• Select your new Wi-Fi network.
• Enter the Wi-Fi password.

Once connected, the blue light will stop blinking and stay solid.
 

Step 3: Reinstall the Printer Driver (if needed)

If the printer still doesn’t appear on your PC:

Go to the official driver page: support.hp.com/us-en
 

Download and install the Full Feature Software and Drivers.

Test the Connection

• Print a Wireless Network Test Report from the printer control panel to confirm it's connected.
• Try printing a test page from your PC.

Additional Tips

• Ensure your PC is on the same Wi-Fi network as the printer.

I hope this helps. 

Take care and have a good day.
