Hi @DanoDano1,

Welcome to the HP Support Community. 

I'd be glad to help you! 

I understand that you are having issues with the wifi connectivity. 

Make sure, your printer and your device are on the same network as 2.4GHZ only. 

I understand your HP LaserJet MFP M140 Printer is not connecting to WiFi, there are several troubleshooting steps you can try to resolve the issue:

1. Restart Your Devices

• Restart the Printer: Turn off your printer, unplug it from the power source, wait for about 60 seconds, and then plug it back in and turn it on.
• Restart the Router: Turn off your router, wait for about 60 seconds, and then turn it back on.
• Restart Your Computer: If you are using a computer to set up the printer, restart it as well.

2. Check Printer and WiFi Settings

• Ensure WiFi is On: Make sure the WiFi is enabled on your printer. Most HP printers have a wireless icon or button that you can press to turn WiFi on.
• Verify WiFi Network: Ensure that the printer is trying to connect to the correct WiFi network. It should be the same network that your computer or mobile device is connected to.
• Check Network Password: Make sure that you are entering the correct WiFi password during the setup.

3. Re-establish WiFi Connection on Printer

• Reset the Network Settings: You can reset the printer’s network settings to clear any previous connections and start fresh.
  • On the Printer: Look for a Wireless or Network menu, and select "Restore Network Settings" or "Restore Network Defaults." This option may vary based on your printer model.
• Use the HP Smart App: Download and open the HP Smart app on your computer or mobile device, then follow the steps to reconnect the printer to your WiFi network.

4. Update Printer Firmware; Click here

• Ensure that your printer firmware is up to date. Outdated firmware can sometimes cause connectivity issues.
  • Using the HP Smart App: Open the HP Smart app, select your printer, and check for any available firmware updates.

5. Check Wireless Network Requirements

• WiFi Band: Make sure your printer is connecting to a 2.4 GHz network if it does not support 5 GHz.
• Proximity: Ensure the printer is within range of the WiFi router and there are no physical obstructions or interference from other electronic devices.

6. Advanced Network Troubleshooting

• Reconfigure the Printer’s IP Address: Sometimes manually setting the IP address can help. You can assign a static IP address to the printer through the router settings.
• Check Router Settings: Ensure that your router is not blocking the printer. You can check if the MAC address of the printer is allowed through the router settings.

7. Perform a Power Cycle

• Power Cycle Your Network: Turn off all devices connected to your network (printers, computers, smartphones, and router). Wait for a couple of minutes before turning the router back on first, followed by the printer and other devices.

8. Reinstall Printer Software

• If all else fails, try uninstalling the printer software from your computer and then reinstalling it. This can sometimes resolve any software conflicts causing the connection issue. Click here
