Apparently some or a lot of players may be experiencing what is called Buffer Bloat. This guy tells you how to fix it in the video below. I've linked everything you may need from his YT below as well. Hopefully this works for some of us here as I know the connection has been abysmal at best sometimes.
Essentially what I gathered is that you want to hardwire your connection directly to your modem and even at that some newer modems will still give you issues. Be sure to check the videos out as I'm not an expert on this.
