I have had fibre for several years at around 42-43 meg stable.
I had a jump upto 50meg around 3-4 weeks ago for a week or so and since then it has dropped back down to 42ish and doesn't seem to imrpove.
I am using an openreach modem and an edgerouter x.
I've tried another router and it gives the same results. Will changing the modem help at all?
