@ELSAN7, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
We see that your HP Laser MFP 138fnw printer not connecting to Wi-Fi on a Windows 11 system, Here’s a step-by-step guide to help resolve the issue:

Check Printer Compatibility and Network

• Ensure your printer supports Wi-Fi Direct or Wireless Network Setup.
• Make sure your Wi-Fi network is 2.4 GHz (this model does not support 5 GHz).
• Place the printer close to the router to avoid signal issues.

Use HP Smart App (Recommended Method)

The HP Smart app simplifies wireless setup.

Steps:

1. Download and install the HP Smart app from the Microsoft Store.
2. Open the app and sign in or create an HP account.
3. Click “Set up a new printer”.
4. Follow the on-screen instructions to connect the printer to your Wi-Fi network.

If the printer is not detected, reset the network settings:

• On the printer control panel, press and hold the Wireless and Cancel buttons for 5 seconds until the wireless light blinks.

Manual Wireless Setup via Embedded Web Server (EWS)

If HP Smart doesn’t work, try this:

Connect your PC to the printer’s Wi-Fi Direct network:

• Look for a network like DIRECT-xx-HP Laser MFP 138nw.
• Password is usually printed on the printer label or in the manual.

Open a browser and go to: http://192.168.223.1

Go to Network > Wireless Setup Wizard and select your Wi-Fi network.

Enter your Wi-Fi password and apply the settings.
