Here's your link http://www.speedtest.net/my-result/5046140366 which looks like BT congestion.
When you moved from Sky to BT, your DLM profile was reset so you were on an open profile.
So all the connection specific DLM settings, such as the interleave depth etc, were all lost. This could be the problem then, since I know that my telephone line is mostly all aluminium and I had a high interleave depth with Sky.
Hopefully the DLM will quickly workout the optimum settings for my line, I doubt there's anything I can do to speed this up?
I dont mind loosing a few mbit speed, or loosing the 5ms that I gained from the move, I just want a 100% reliable connection like I had with Sky asap!
I just restarted my Skyhub, which has resolved the issue for now, looks like it must have been an insane number of errors per second to reduce my speed as it did in the speed test linked above.
Before router restart:
5. VDSL uptime: 0 days, 06:00:22
6. Data Rate: 6860 / 32212
7. Maximum Data Rate: 6859 / 37537
8. Noise Margin: 6.0 / 5.4
9. Line Attenuation: 38.0 / 26.7
10. Signal Attenuation: 0.0 / 0.0
After router restart:
5. VDSL uptime: 0 days, 00:00:12
6. Data Rate: 6962 / 32393
7. Maximum Data Rate: 7012 / 38846
8. Noise Margin: 6.1 / 6.2
9. Line Attenuation: 38.0 / 26.8
Pity I can't view the interleave depth or CRC/FEC stats in the homehub. If this problem continues I can connect up my HG612 to view the detailed line stats, though hopefully DLM will actually do something soon.
I have to question why a DLM reset is done when migrating ISP - surely customers would want their new connection to be as stable as their old one, and not have to go through the retraining period again etc, doesn't make sense to me!
Surely in this day and age they could simply copy all the connection specific settings (sync history, interleave depth etc) and automatically apply those settings when doing the migration.
It was probably the decision of the same person that decided to roll out all these useless ECI cabinets that can't do G.INP!
Oh, just thought I'd mention I am indeed on an ECI cabinet, are there known issues between the home hub 5B and ECI cabinets? As I said my HG612 worked flawless for over a year with Sky.
