Hi @Gab48,

Welcome to HP Support Community.

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

The blinking Wi-Fi symbol on your HP ENVY 6455e All-in-One Printer typically indicates that the printer is either not connected to a wireless network or is in setup mode, searching for a network to join. Here are some steps to diagnose and fix the issue.

Check the Network Status

• Ensure that your Wi-Fi network is active and working correctly. Verify other devices can connect to the network.

Restart Devices

• Printer: Turn the printer off, wait for 30 seconds, and turn it back on.
• Router: Restart your router by unplugging it for 30 seconds and plugging it back in.

Reconnect the Printer to Wi-Fi

• If the printer has lost its connection:
  1. On the printer, press and hold the Wireless Button (or Wi-Fi icon) until the Wi-Fi light blinks.
  2. Open the HP Smart app on your phone or computer.
  3. Follow the prompts to reconnect the printer to your Wi-Fi network.

Printer in Wi-Fi Setup Mode

• If the printer is new or reset, it may be in setup mode.
  1. Check if the Power button light blinks.
  2. Within 2 hours of setup mode activation, use the HP Smart app to add the printer.
  3. If setup mode times out, reset the printer:
     • Press and hold the Cancel and Wireless buttons together for 3 seconds. This resets the network settings.

Update Printer Firmware

• If the connection issue persists, ensure the printer firmware is up-to-date.
  • Open the HP Smart app > Select your printer > Check for firmware updates.

Check for Interference

• Ensure the printer is close to the router (within 6 feet or 2 meters) and not obstructed by walls or electronic devices that can interfere with the signal.

Factory Reset (If Necessary)

• If none of the above works:
  1. Turn off the printer.
  2. Hold the Power button and press the Cancel button 6 times.
  3. Release the buttons. The printer will restart in its factory default state.

I hope this helps.

Take care and have a good day.
