Hi @Garethzinger,

 

Welcome to The HP Support Community.  

 

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

 

I understand you are facing an issue with your HP ENVY 6455e All-in-One Printer not connecting to WiFi and showing as offline, try the following steps:
 

Check WiFi Connection:

  • Ensure your WiFi network is working properly by connecting other devices (e.g., smartphone, laptop) to it.
  • Verify that the WiFi signal is strong where the printer is located.

Restart Devices:

  • Turn off your printer, router, and computer.
  • Wait for about 30 seconds.
  • Turn on the router first and wait for it to fully initialize.
  • Turn on your printer and then your computer.

Printer Network Reset:

  • On the printer, press the Wireless button and the Cancel button simultaneously, and hold them for 5 seconds until the Power button blinks. This will reset the wireless settings.
  • Reconnect the printer to your WiFi network using the HP Smart app or the printer's control panel.

Use HP Smart App:

  • Download and install the HP Smart app on your computer or smartphone if you haven't already.
  • Open the app and follow the instructions to add your printer and connect it to your WiFi network.

Update Printer Firmware: Update the firmware on an HP printer

  • Ensure your printer's firmware is up to date. You can do this through the HP Smart app or by visiting the HP Support website.

Check Network Settings:

  • Make sure your router is not set to a mode that the printer does not support (e.g., dual-band routers should be set to 2.4 GHz, as some printers do not support 5 GHz).
  • Ensure there are no MAC address filtering settings on your router that could block the printer from connecting.

Disable VPN and Firewall:

  • Temporarily disable any VPN or firewall software on your computer that might be interfering with the printer's connection.

Assign Static IP Address:

  • Assign a static IP address to the printer through your router's settings. This can sometimes resolve connectivity issues.

I hope this helps. 

 

Take care and have a good day.
