Well I hope nobody has to wait as long as I have for DLM to increase their profile. Mine had been locked on 52.27 without budging since 10th May. (Before then it had been around the 65-67 Mark).
Just after midnight yesterday (6th August) my Homehub connection dropped for about 15 minutes. Upon reconnection it has DROPPED the profile to about 48Mbps
Shocked at the further reduction, I rebooted the Openreach modem, but was nicely surprised when I found the profile had risen to 56.64.
Now my line sounds much quieter as well so it's possible that they have finally gotten around to sorting out the intermittent noise problem on their own initiative (after denying there was any problem and closing the fault months ago). But if it's not due to that then that's a long time for DLM to do nothing.
Still, a long way to go until i'm back up at February levels.....
