My fibre is much better than going through the old copper wires.
Although, fibre optics only go so far. Fibre Optics here go to a hub in the centre of town, about half a mile away.
From there it travels through the regular copper phone wires to get to us.
So, it's still affected by weather.
What's the wheather like where you are, by the way? It can make a difference, particularly if stormy.
And are you connecting to the internet in your house via wifi or a wired connection?
