@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.
- Turn on the printer.
- Press and hold the Wireless button (📶) and the Cancel button (❌) together for 5 seconds.
- 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.
