Before I had this speed drop I have tried as much as I can. I tried a different router no change, I have had chorus out he says all looks fine but can't explain the drop in speed. I have changed filters I just don't know what else I can do?
Before the drop in speed downstream line was 30000 kbits
maximum downstream was approx 32-33 down kbits (both were close together)
downstream noise safety coefficient reported 8.9 - 9.1
line attenuation 47.2 or 47.8 so nothing changed there.
on speedtest I easily got 28 - 30 down
now I am lucky to get 20 - 21 such a big drop.
no matter what I do, resets etc nothing works.
here is a screenshot of what I get now
