Hi Williams, Esther,
Welcome to Microsoft Q&A forum. I'm happy to help.
Regarding your information you have new internet services with new Wi-Fi password, I assume that you have new AP. The new Wi-Fi might have the frequency and/or channel that beyond support range of your printer.
You may provide me the printer model, so I can look up for its Wi-Fi support to see if it's compatible with your new Wi-Fi.
Thank you for your time.
