Thanks for posting and a warm welcome to the community.
Sorry to read that you are experiencing slow broadband speeds.
From checking your connection there is high traffic during peak hours which I have raised to our networks department for more investigation. Once I have more information I will let you know.
I also noticed that the downstream power levels are too high and I would like to arrange an engineer appointment to adjust these for you. I've sent you a PM (purple envelope icon, right corner) requesting some details.
