double annoyed because all of the planned work to install a second cabinet in our village for FTTC suddenly got cancelled and lo and behold, our village's FTTC enablement date has gone from 31 Mar 2011 to "Sorry, BT Infintiy is not due to be rolled out in your area"!!

Yup, as you'll see from my own thread about bt constipation, I've had the same delays and the same very recent message. However Roberto kindly quoted a link to
http://www.dslchecker.bt.com/adsl/adslchecker.welcome
which did give me a date - albeit September 30!

My current stats are:

Connection time 0 days, 0:03:29

**That's not been up long, <edit> that's only 3 1/2 minutes! </edit> Are you still getting line drops? You might be able to tell from the error log (It's found in the advanced settings, troubleshooting, if I remember)

Downstream 1,024 Kbps

**Not quite enough for 1Mb profile.

Noise margin (Down/Up) 9.4 dB / 7.0 dB

**And there's why. A 9dB target margin will lose you a few hundred Kbps over a 6dB margin.

FEC Errors (Down/Up) 274 / 0

**Fine. FEC errors are corrected as part of having interleaving on.

CRC Errors (Down/Up) 0 / 2147480000

**It's a bug, igore the upstream CRC.

HEC Errors (Down/Up) nil / 0
Error Seconds (Local) 0

Also fine.

Now getting a top down speed of about 340kbps when doing a speed test on speedtest.bbmax.co.uk

**Try using speedtester.bt.com, this will tell you what profile you currently have.

To me, there are two options,

- If BT_Care offer to completely reset the profile, give you back the 6dB margin and restart training, take it. Try and plan it so you switch the router on during daylight hours, then just leave it be for the 10 days.

- Wait. If the line stays stable, the noise margin will reset back to 6db and you will then get your 1Mb profile shortly after.

Hi shtu, thanks for the lowdown. To answer your question, the reason it hadn't been connected long was because I accidently restartwd the router when I moved it by grabbing the side! The reset Byron is a little too easy to press by accident. Hardly ideal given that I should be leaving it to stabilise. Having said that, the stats were virtually identical this morning before I reset the router.

I suspected it was the jump in noise margin that was hammering me too. I did do a bt speed test about an hour ago and my profile is 448 (or 400 and something) down stream so it has risen since this morning but is obviously still nowhere near where it should be. Like you say, hopefully BT_Care will offer to reset my profile and SNR. I will let youknow how I go but I don't intend to touch the router now unless someone tells me to!

Thanks
Andrew

Damn the auto correct on my iPhone! Since when did button sound like Byron? I also forgot to mention that I'm not getting disconnects anymore so the exchange issues definately seem to have stabilised...

Hopefully I should hear from BT_Care shortly.

Thanks
Andrew

From recent experience, a change of 1 step in profile tends to take around 6 to 7 days rather than the 5days for small changes suggested on Kitz's site.

Good, had me worried there. Profiles for your reference,

http://www.kitz.co.uk/adsl/IPprofile.htm#IP_and_bRAS...

@MHC, yep, so realistically we're looking at 2-3 weeks for this to climb back on it's own, 10 days or so for the noise margin to drop back to 6dB, and then a further week for the profile to increase to 1Mb.

And of course, that's assuming that the line stays stable through this (though it doesn't look all that bad). Really bad luck that the fault hit when it did.

And what I hope is that the disconnects have stopped because they fixed a fault, and not because the noise margin was raised.

I suspect we'll have to wait and see on that one.

Excellent! I've just check and see that i am due for Sep 30th too. At least it would see that BTo still have plans to upgrade the cabinet at some point.

Many thanks for pointing out the link!
Andrew

I can appreciate your frustration re conflicting information!

From
http://www.samknows.com/broadband/exchange_search
it appears that even Sam doesn't always know. He still shows my exchange as RFS (ready for service?) on 1 March 2011.

All,

Just a quick post to say thanks to everyone for all the assistance. BT_Care have been excellent and due to their intervention I think my problems may now be over. They kindly arranged to have my Target SNR reduced down to 6db again and I've been reliably connected at 1248kbps for 2 days now (would have been longer had we not had a power cut!). My IP profile has increased back up to 1000K which is as good as I can ever expect it to be living so far from the exchange.

They've asked me to monitor the connection for stability over the next few days but touch-wood it's problem solved for now.

Thanks again everyone for the assistance. I can comment that the ADSL filter was a very good purchase and for £12ish was well worth it to get my sybc up from 1024kbps to over 1200kbps. The 2Wire 2700 may well be very good although I found it took over 10mins to sync (it was rand new and still wrapped in celophane but I guess you never know...) and when it finally did so it was no quicker than the BTHH2. I'm sure it's a better device than the HH2 - I especially like the amount of data that it can reveal about the connection, for example I learned that my attenuation is well over 70db in reality. But given that my HH2 seems reliable at 1248kbps and the 2700 only cost £13 I'm happy to keep it as a spare!

Kind Regards,
Andrew
