APPLE PRODUCTS WONT CONNECT TO XFINITY WIFI

non of my products will connect to my home WiFi. It works everywhere else but my house. Is there a reason why only xfinity WiFi doesn’t connect. Every time i enter the password it tells me it’s the wrong password when it’s indeed the correct password. My antenna isn’t broken, i can still connect to Bluetooth devices. But i can’t connect to my home WiFi.
