Hi @Tarekk6 

Welcome to the HP Support Community! 

Thanks for posting your query! We're here to help you get back up and running.

Connecting your HP LaserJet MFP M139-M142 to Wi-Fi can sometimes be tricky. 

Here’s a step-by-step guide to help you get it set up:

Reset Network Settings:

• Press and hold the Wireless and Cancel buttons on the printer simultaneously for about 5 seconds. This will reset the network settings and put the printer into setup mode. The wireless light should start blinking.

Use the HP Smart App:

• Download the HP Smart app on your computer or smartphone.
• Open the app and select "Set up a new printer."
• Follow the on-screen instructions to connect the printer to your Wi-Fi network. You’ll need your Wi-Fi password for this step.

Ensure Compatibility:

• Make sure your Wi-Fi network is set to the 2.4 GHz band, as some HP printers do not support 5 GHz networks.
• Verify that your network uses WPA or WPA2 security (open networks or WEP security may not work).

Check Router Settings:

• Ensure that your router’s WPS (Wi-Fi Protected Setup) feature is enabled if you’re using the WPS method. Press the WPS button on your router and then press the Wireless button on your printer within 2 minutes.

Update Firmware:

• Visit the HP Support website to check for firmware updates for your printer. Updating the firmware can resolve connectivity issues.

Restart Devices:

• Turn off your printer, router, and computer. Wait for about 30 seconds, then turn them back on.
