Hi @jouj,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If your HP Smart Tank 6400 printer is not connecting to Wi-Fi, you can try the following troubleshooting steps.

Check Wi-Fi Settings on Printer:

• Ensure that the Wi-Fi is enabled on your HP Smart Tank 6400 printer.
• Navigate to the printer's control panel or settings menu to verify that it is connected to the correct Wi-Fi network.

Restart Printer and Router:

• Turn off your printer and then turn it back on after a minute.
• Restart your Wi-Fi router to ensure that it is working correctly.

Reconnect to Wi-Fi:

• On the printer's control panel, find the Wi-Fi settings or setup option.
• Select the Wi-Fi network you want to connect to and enter the password if required.

Update Firmware:

• Check if there is a firmware update available for your printer. Visit the HP support website, find your printer model, and download and install any available firmware updates.

Check Wi-Fi Signal Strength:

• Ensure that the printer is within the range of your Wi-Fi router. If the signal is weak, consider moving the printer closer to the router.

Use WPS (Wi-Fi Protected Setup):

• If your router supports WPS, you can use this feature to easily connect your printer to the Wi-Fi network. Consult your printer's manual for instructions on how to use WPS.

Reset Network Settings:

• You may try resetting the network settings on the printer and then reconfigure the Wi-Fi connection. Be aware that this will erase any existing network settings, so make sure you have the necessary information (Wi-Fi password, etc.).

Check for Interference:

• Ensure that there are no electronic devices or physical obstacles causing interference with the Wi-Fi signal.

Printer and Network Compatibility:

• Confirm that your printer and Wi-Fi network are compatible. Ensure that your Wi-Fi router uses a compatible frequency (2.4GHz or 5GHz) and security settings.

By following these steps, you should be able to troubleshoot and resolve the connectivity issue with your HP Smart Tank 6400 printer.

I hope this helps.

Take care and have a good day.
