Hi @timeshort,

Welcome to the HP Support Community.

Thank you for posting your query.

I am sorry to hear that your HP printer is experiencing issues connecting to the network, especially when connected via Ethernet, I would request you to please follow the steps:

Access Printer Web Panel

• Open a browser and type the printer’s IP address directly (e.g., http://192.168.x.x).
• If it times out, the printer may not be on the same subnet or may have lost its IP lease.
• Try pinging the IP from your laptop (ping 192.168.x.x) to confirm connectivity.

Reset Network Settings

• On the printer, go to Network Settings → Restore Network Defaults.
• Reconnect the printer to the router via Ethernet.
• Allow a few minutes for the router to assign a new IP.

Re-add Printer on Laptop

• Remove the printer from Devices & Printers (Windows) or Printers & Scanners (Mac).
• Add it again using the IP address or network discovery.
• Ensure it’s set as the default printer.

HP Smart App

• Open HP Smart and select Add Printer.
• If it finds the printer but fails to connect, manually enter the IP address.
• Update HP Smart to the latest version.

Firmware & Driver Updates

• Visit HP’s support site for your printer model.
• Download and install the latest firmware and drivers.
• Firmware updates often fix connectivity issues.

Hope this helps, Please revert if the issue persists.

Take care and have an amazing day!
