Wi-Fi connection issue

I installed 2 Ring cameras at a house I had for sale. No issues setting them up. After the house sold I brought the cameras to my house to set them up. I went into my profile settings and updated the new address. When I try to connect I get a prompt that asks if I want to join wi-fi network "Ring Setup b7"? When I click on "join" I get another prompt that says "Unable to join the network "Ring Setup b7". What is going on? FYI I'm not real tech savvy.
