Can you help me troubleshoot my Epson printer?

I have an Epson xp-420 printer. Simple and cheap.

I was able to print for months, and now suddenly it has lost its connection to my WiFi.

I have restarted my router. I have restarted the printer. I have reset the printer to default settings. It will not connect to the WiFi. It can detect the WiFi, but it will not connect. I’m certain I’m putting in the correct WiFi password.

I have searched online, but I have not been able to find any help.

Ideas?

If this does not work, can you recommend a replacement printer I can buy that will not drop the WiFi connection?

I’m using a Dell PC running Windows 10. No issues with the computer.
