Not ideal, but then I find I get many more re-syncs on WBC than on Max, eg one a day rather than one a month. The technology is just pushing the line further.

Now seems it's starting to look better... 1:24 AM

Test1 comprises of Best Effort Test:  -provides background information.
    Your DSL connection rate: 4636 kbps(DOWN-STREAM),  1026 kbps(UP-STREAM)
    IP profile for your line is - 4000 kbps  :thumb:
    Actual IP throughput achieved during the test was - 3486 kbps

If you wish to discuss these results please contact your ISP.

BTW touched nothing on the wiring/router, so just  :fingers: it will continue to improve.

Interestingly, NM at 13.6dB right now...

Speedtest.net confirms improvement. Just hope there is more room to go (guess it's all bets on line noise)

Just so you won't wonder, find the chart of profiles by connection speed at the bottom of this page:

http://www.dslzoneuk.net/adslmax_explained.php

You can see that the bottom end of 4000 is 4544.

Oi..! Meant that just hope the NM ratio continues to fall  ;) Know with the current profile what I'm getting is as much as can be squeezed out.

We'll see how stable this baby is throughout. Surpirsed the chains are moving faster than predicted... we were betting on getting stuck on a 2.5 kbps profile for days after the repeated re-syncs, it now moved a bit. Hopre progress continues.

NM ratio back to the 14.6db range... need to check what's going on here. It's fluctuating by 2db or thereabouts. Maybe the guys at IDNet could do a line test for me..?

They could, but a 2db fluctuation is not that unusual.

OK, seems no joy lasts forever with BT...  :mad:

Test1 comprises of Best Effort Test:  -provides background information.
   Your DSL connection rate: 4147 kbps(DOWN-STREAM),  1051 kbps(UP-STREAM)
   IP profile for your line is - 3500 kbps  :rant2:
   Actual IP throughput achieved during the test was - 3220 kbps

If you wish to discuss these results please contact your ISP.

So it's back to square one, and there has been NOTHING changed to the local wiring, etc. Just don't know what the heck to do. The IP profile is changing every 24 hrs. How on earth would this stabilise..? It's like a ping-pong ball bouncing against the sides of a box.

WBC is more sensitive to noise than Max was, due to the higher frequencies used. It looks like your line is susceptible to noise, unfortunately.

By OUR you mean MINE..? Well, it could be the wiring to the exchange. It seems a lost battle  :bawl:

Seems the last resort will be to plug the router to the test socket and loose my phone, etc., for 24 hours (have moved the cordless base 2 rooms away from the router, on an extension...) But wanted to keep things quiet for a while. Ring wires are all out. All connections tidied-up. Next bit would be to rewire my house with fiber optic..!  :mad:

Have you done the MW radio 'walkabout' test?

Not with a MW radio but a walkie-talkie, that's when I detected the transformer of my cordless phone base was emitting lots of RF interference (and was sitting just by the BT main box). Then, it seems nothing much changed. Interestingly the area is polluted with wireless router/modems (I can pick at least 10 to 12 signals in my PC, 1/2 of them to which I could be able to connect given the signal strength). Maybe that's causing the issue..?

It won't be helping as it will certainly increase crosstalk on the main cable.

Unfortunately there is not much I can do about that, but it would be unbelievable the WBC service can be so sensitive that a technology pretty much widespread these days (such as wireless routers) could render it unstable.

I doubt the wireless side is the problem, tbh. For the past year, we have seen degradation of line speeds as ADSL take up increases. WBC (ADSL2+) is more sensitive to noise, so it's going to be more sensitive to crosstalk on the cable.

TBH, whatever it is, it's simply annoying. It can't be that in a first-world economy you cannot get decent Internet access due to infrastructure bottlenecks (of course, I'm not ruling out my own side of the equation, as my cabling might need revamping... but, looking at the forum...)

I know. Fibre is the only solution, but I expect that won't reach here in my lifetime. :(

Even in South America you get cities pretty much all wired over in fibre optic, since the 80s. It's just amazing.

No, sadly it's just BT. :(

OK, almost 2 days on and no change so far...

NM still pegged at 15.3db. Wonder what next..?  :dunno:

Up to five days for a profile change (which you're not due, that profile is correct for that sync), a continuous sync for 15 days to get the target NM to drop by 3db, repeat until it reaches its lowest level. :(

Piss  :mad:

But interstingly BT changed the profile/NM down, then up again within 24 hours..? How come..?

Also reading on an e-mail from James, where he suggested to reboot the router every 24 hours to help the circuit train, which is not what you and others in the forum seem to suggest as best course of action. I'm  ???
