Hi @LINDA4877,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your printer!

We're thrilled to have the opportunity to assist you and provide a solution.

Try these steps:

Check Network Compatibility and Connection:

• Ensure the printer and the computer or mobile device are both connected to the same Wi-Fi network.
• Make sure your router is functioning correctly and supports the printer’s wireless connectivity standards.

Printer Restart:

• Turn off your printer, wait for about 60 seconds, and then turn it back on to reset its networking components.

Wi-Fi Network Settings:

• Verify that your router’s Wi-Fi band is compatible with the printer. Many printers work best with 2.4 GHz Wi-Fi rather than 5 GHz.
• Ensure that the Wi-Fi password entered during setup is correct.

Restore Network Settings:

• Restore the printer’s network settings to default and try connecting to the Wi-Fi network again.
• On touchscreen models, access Setup > Network Setup > Restore Network Settings.

Firmware Update:

• Update the printer’s firmware via the HP website using a wired connection or by downloading the firmware update to a thumb drive.

Use HP Print and Scan Doctor:

• Download and run the HP Print and Scan Doctor tool from the HP website. This tool can automatically diagnose and resolve connectivity problems.

Router and ISP Check:

• If you continue facing connectivity issues, restart your router and check with your Internet Service Provider to ensure there are no network issues.

I hope this helps.
