Hi @LA113,

Welcome to HP Support Community.

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

If your HP Smart Tank Plus 551 isn't reconnecting to Wi-Fi after a power outage, here are some troubleshooting steps you can follow.

Restart Devices

• Restart Printer: Turn off the printer, unplug it from the power source for 30 seconds, then plug it back in and turn it on.
• Restart Router: Unplug your router, wait for about 30 seconds, and plug it back in. Allow it to fully restart.
• Restart Computer/Phone: Restart the device you're trying to print from.

Reset Network Settings on Printer

• Restore Network Defaults:
  1. On the printer's control panel, go to the Wireless menu.
  2. Select Restore Network Settings or Restore Defaults.
  3. Confirm the action.

Reconnect Printer to Wi-Fi

• HP Smart App:
  1. Download the HP Smart app on your mobile device or computer if you haven't already.
  2. Open the app and add a new printer.
  3. Follow the on-screen instructions to connect your printer to your Wi-Fi network.
• WPS Push Button Method:
  1. On your printer, press and hold the Wireless button until the wireless light starts blinking.
  2. Press the WPS button on your router within two minutes.
  3. The printer should automatically connect to the Wi-Fi network.

Check Wi-Fi Signal

• Make sure the printer is within range of your Wi-Fi router.
• Ensure there are no large metal objects or other electronic devices that might interfere with the Wi-Fi signal.

Manual IP Address Configuration

• Set a Static IP:
  1. Print a Network Configuration Page from the printer's control panel.
  2. Note down the printer's current IP address (if any).
  3. Open a web browser and type the IP address in the address bar to access the printer’s Embedded Web Server (EWS).
  4. Go to the Network or Wireless settings.
  5. Set a manual IP address that is outside of your router's DHCP range but within the same subnet.

Check Router Settings

• Band Compatibility: Ensure your router is broadcasting on a 2.4 GHz band, as many printers do not support 5 GHz bands.
• MAC Address Filtering: Ensure that your router isn’t blocking the printer’s MAC address.

Update Firmware

• Ensure the printer's firmware is up to date. You can check for updates through the HP Smart app or the printer's control panel.

Reset Printer to Factory Settings

• If all else fails, you can reset the printer to factory settings:
  1. Go to Setup on the printer's control panel.
  2. Select Printer Maintenance > Restore > Restore Factory Defaults.
  3. After the reset, follow the initial setup instructions to reconnect to Wi-Fi.

I hope this helps.

Take care and have a good day.
