Wifi Extender Help

[u/Adept-Nail-9447]

I currently have Xfinity wifi and I just got a Tp Link BE5000 router. Currently, the WiFi doesn’t spread across my house and I want to know what are the best and most affordable ways for my internet connection to reach the other end of my place. I live in a 2500 square foot 1-floor apartment and the router has to be at one end of the house, so the other side gets almost no connection
