Xfi "let's try that again" error message

No matter what I try to do using Xfi, I get only an error message saying "let's try that again". Cannot connect.

Also, trying to connect an HP printer to the wireless network and it will not accept the password. Says I have to do push a WPA button on the router or enter the router's config but no idea how to do that, and that's why I was trying to get into Xfi to look up more info.
