Extremely and unusually slow new cable connection

[PANOS]

Hello sorry for the english message

I have a new cable connection established at home. I plugged the router to the wall and it started. The first day it was super slow but I thought its part of the process. Today I came back home to find that I cant even load a youtube video without waiting 1 minute. Two windows and I have to wait 5 minutes.

Can I get some information on why is this happening ? Thank you
