Printer connects intermittently. Always shows having strong wireless signal strength.

[CurtM78]

I have had two different brand printers and two different Wi-Fi, Internet companies, and the problem persists. I was able to contact HP support while this new printer was under warranty and they temporarily solve the issue. Now back to not being able to print via Wi-Fi

@CurtM78, Welcome to HP Support Community. 

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

It sounds frustrating to deal with a printer that keeps dropping its Wi-Fi connection despite showing a strong signal. Since you've already tried different ISPs and even had temporary success with HP support, the issue likely lies elsewhere. Here are some targeted troubleshooting steps that might help:

Static IP Address

• Problem: Printers often lose connection if their IP address changes frequently.
• Fix: Assign a static IP address to your printer via your router settings or the printer’s embedded web server (EWS).

Wi-Fi Band Compatibility

• Problem: Some HP printers struggle with 5GHz networks.
• Fix: Ensure your printer is connected to the 2.4GHz band, which has better range and compatibility.

Power Saving Settings

• Problem: Printers may go into a deep sleep mode and lose Wi-Fi connection.
• Fix: Disable or adjust sleep/eco mode settings in the printer menu.

Firmware Update

• Problem: Outdated firmware can cause connectivity bugs.
• Fix: Check for and install the latest firmware via the HP Smart app or the printer’s web interface.

Router Settings

• Problem: Some routers have settings that interfere with printer connectivity.
• Fix:
  • Disable AP isolation or client isolation.
  • Enable Multicast and UPnP.
  • Ensure DHCP lease time is long enough (e.g., 24 hours or more).

HP Smart App & Reinstallation

• Fix: Remove the printer from the HP Smart app and your system, then reinstall it:
  • Reset the printer’s network settings.
  • Re-add it using the HP Smart app.

I hope this helps. 

Take care and have a good day.
