Please accept my apologies for the decrease in sync speed.
After testing the line, your connection profile is set at 0.128M - 80M and the account connection profile is matching the sync rate of 53.1Mbps. I'm afraid that a profile reset will not have any impact on your current connection speed.
I can see a clear correlation in drops in the circuit and the decrease in speed so now the circuit has remained stable DLM should naturally start to increase performance back to previous levels.
