Hello Tvsteven,

Thank you for providing all the details regarding the Wi-Fi connection issue you are experiencing with your Apple TV.  I found an article with some steps you can take to troubleshoot an issue like this.

I recommend reviewing the full article, but the section titled "If you can see your Wi-Fi network, but you are unable to connect to it" specifically stands out to me for the situation you described:
