Progressively degrading ADSL download speed

Quote from: Aled

Your connection is looking good and has maintained speed and connection over the weekend. Luke's order is due to complete by tomorrow morning, so let us know how you get on.

Thank you Aled.
The resync following the removal of the upstream cap happened this morning around 03:15 UTC.
I have attached the RouterStats graphs, which show:
- Upload sync is now 800k.
- Download sync dropped to just under 5Mbps.
- Noise margins have changed significantly. Is this as expected?

Hi,
A resynch in the early hours is the worse time for attaining optimal synch speed, as the line would be affected by night time AM radio interference.  A resynch during day time will deliver optimal DS synch and establish a new bench mark for further monitoring.
What is of some concern is the size if the SNRM shift on the resynch - 3.5dB is somewhat greater than is usually seen fir night time interference.  Can you therefore please do a daylight resynch, post router stats, BTw speed test results and PN portal current speed.  Please keep RouterStats running 24x7 so we can inspect the day-night transitions.
