Thank you for the clarification. Let me try few tests and then I will let you know.
I am very grateful for your advice.
thanks a lot.

I assumed you have full fibre, the ONT is the optical modem, but if you don't have an ONT you must have a G.fast service. In which case it is not possible to bypass the hub.
Can you post a screenshot of your hub connection stats. Advanced settings > technical log > information
Correct is a G.fast service. Not full fibre.

Is it readable? Otherwise I try again with a new photo
OK, you are getting 329Mbps sync speed to the hub. It might simply be congestion in the backhaul network that is causing the slow download speed. Try running a speedtest at a quiet time of the day ( very late night or very early morning) and see if the speed changes.
