I wonder if anyone has an explanation for the very low IP profile figure, illustrated below, when compared to the BT throughput figure on this G.DMT ADSL service via a HH6.
Heres a corresponding DSL Reports speed test which is probably nearer the truth as yet another statistical calculation.http://www.dslreports.com/speedtest/13668605
Here's what firstname.lastname@example.org
They also refuse to initiate a lift and shift as recommended by the eighth BT Openreach engineer.
I need to concentrate on this line alone, and no other lines that you may be monitoring. I can’t take into account any other line stats.
There is no reason to change the port with no evidence of a fault (currently). I do not agree that the sync rate is fluctuating substantially, but it does fluctuate. Once again, broadband is ‘rate adaptive’, and it will fluctuate.
A hub reboot will cause a resync, sometimes at a different rate. But as DLM monitors the connection for errors and noise, gradually we’d expect that sync rate to level out over time. This appears to be what’s happening with this line.
I would investigate the IP profile discrepancy if it was causing problems with the throughput. The IP profile has absolutely no bearing on the DSL connection rate, so is not a factor in this case.
Swapping to G993.3 is not an obvious step to take here. There is no reason a circuit performing well below 8mbps should be moved to ADSL2+, and I have seen numerous faults in the past which have been resolved by taking the very opposite measure and moving to 8MB WBC.
