Moved to a new house and the internet is extremely slow - eviltoast

Hey! So recently I switched houses and I’ve noticed that my internet has become extremely slow and isn’t like before, I used to get 70+mbps in my old house and now I get a meagre 15-20 mbps, it’s really problematic as I am having trouble doing regular internet tasks/downloading stuff or playing an online game.
Any help? (I’m not so experienced with network and internet related issues)
