Telephone lines generally dont have faults that happen around the same time each day.

What may be happening is some radio frequency noise is being generated at this time of day causing a problem. If you know the IP Profile is following the speeds which it will, no need to run the BT test to find it out, the router statistics are much more informative in terms of line performance

Have you had any work done on, or changes to, your central heating in the last 12 months? Or has a next-door neighbour?

No fitness fanatic in the area bought an indoor running or cycling machine?

Yes, I been all through all this since November - there has been no change in my immediate environment. I ruled out central heating (I do not have CH, but neighbours do) as you could expect it to kick-in the same time every morning (i.e. like 04:00) - but my disconnects happen any time between say 03:00 and 07:00 - and only ONCE a day.

Well, could/would BT turn OFF this profile thing? I mean, I can connect at say between 5200/6700 and hold a perfect connection for 23h:59m:30s a day - then something happens, and I reconnect. Why can't I reconnect at the same speed? Why drop 50% off the line speed for 1 disconnect? It's almost like BT want me to change to their fibre network.

BTW, here is todays stats:

Line Status:Connected
DSL Modulation Type:ADSL_2plus
Annex Type:Annex A/I/J/L/M
 	             Upstream	Downstream
Current Rate (Kbps)	1033	3071
Max Rate (Kbps)	        1036	10996
SNR Margin (dB)	        9.1	6
Line Attenuation (dB)	22.4	42
Errors (Pkts)	         0	0

Why can't I reconnect at the same speed?

Because the noise that made it drop the first time is still present and inhibits the speed it can reconnect at.

If you have 3071k downstream sync with a 6 dB SNR margin and a 42 dB attenuation then there's a fair amount of noise present when those stats were taken. If the noise had gone away the SNR margin would be up.

ETA - Could you leave it off overnight ?

In reply to a post by yarwell:

Well, that is no advantage as when I reconnect my profile gets lowered each time (plus I run a few services).

So this is what I do not understand. How can I get any improvement if the BT equipment reduces my sync rate/profile on every disconnect? It never ever used to do this until Sep/Oct last year.

Nick

you haven't shown us any evidence that it is lowered each time you connect unless I missed it.

You've shown that something happens that makes it reconnect and it connects at a lower speed because of the something.

My idea was to avoid the something by not being online at the time - however if the SNR margin doesn't come up the problem is still present - unlike your OP where the SNRM was high so it had gone away.

I'm focussing on the sync rate here, the IP Profile is just a derivative / consequence.

Extracted the posted stats thus far :-

Current Rate (Kbps) 1128 3070
SNR Margin (dB) 5.9 17.4 ADSL_G.dmt.bis

Current Rate (Kbps) 1117 3071
SNR Margin (dB) 5.9 6.1 ADSL_2plus

Current Rate (Kbps) 1033 3071
SNR Margin (dB) 9.1 6 ADSL_2plus

Current Rate (Kbps) 928 3072
SNR Margin (dB) 10 24.5 ADSL_G.dmt

Current Rate (Kbps) 1131 8771
SNR Margin (dB) 6.6 3.8 ADSL_2plus

OK, so here at stats at the mo:

Line Status:Connected
DSL Modulation Type:ADSL_2plus
Annex Type:Annex A/I/J/L/M
 	            Upstream	Downstream
Current Rate (Kbps)	1033	3071
Max Rate (Kbps)	        1028	11252
SNR Margin (dB)	        8.6	6
Line Attenuation (dB)	22.4	42
Errors (Pkts)	          0	0

Now, I should be able to sync a lot higher than that, agree? But doing the bt test diagnostics thing, it reports my line max speed is now 4mb. Well it isn't, as I said, I used to sync between 5000/6700. So I cannot sync any higher due to being capped. And that cap gets lower and lower on each disconnect. In a few days time it will report 2700 (or something) max speed.

I think Enta support got fed-up resetting the line, so I will not bother then again until next week.

Nick

This is after being connected at 5420 on Sunday/Monday - and remember I tried adsl/adsl2/adsl2+ a few times too.

Wait 'til Friday, I will see then.
