I've stopped working with obsolete xDSL network devices. I have an ISP Fiber who installed Fiber to the CURB and Fiber to the Home simultaneously just to make money. They installed the obsolete fiber to the curb systems to milk people into making them think that xDSL is a way for the future.
Meanwhile on quite stable 4G Networks they give the speeds that you see in the screenshot. I can reach more than 40 MBit per second! I would rather be ad hoc on the internet, then have a slow obsolete 10 MBit connection over two copper wires.
I am finally enjoying the internet again when it comes down to speed
