My parents recently got moved over to a new infill cabinet last year, which improved speeds from 12/1 to a very respectable 76/20. The line has been running at 76/20 for the past few months without any problems whatsoever, but DLM decided to resync the line overnight a week or so ago.
Since the line resynced, the speed has dropped by over half - with the IP profile falling from 75.68 to 38.67, the upload profile remains at 20 - but actual throughput is around 9Mbps.
Putting our number into the DSL checker shows that a clean line should achieve between 74.2 and 55 Mbps, with an impacted line that falls to 62.9 - 38.8. This puts our new speed at or below the quoted impacted low, when previously we were achieving slightly above the clean high speed.
With the drop as severe as it is, would it be possible to get the DLM reset - or will it be a case of waiting for a few months and hoping it decides to up the sync rate in it's own time?
I'd post line stats but unfortunately BT provided us with an ECI modem, so I can't get the stats.
