If I new where to find a laughing smiley here, I'd post a row of em!

These are the stats this morning-

At start-up this morning, with ADSL2 ticked:
ADSL Status
Parameters
DSP Firmware Version A2pB025f.d22k
DMT Status No Defect
Operational Mode ADSL2
Upstream 1080
Downstream 7047
SNR Margin(Upstream) 6.5
SNR Margin(Downstream) 7.8
Line Attenuation(Upstream) 22.7
Line Attenuation(Downstream) 42.5

After changing to ADSL2+:
ADSL Status
Parameters
DSP Firmware Version A2pB025f.d22k
DMT Status No Defect
Operational Mode ADSL2+
Upstream 1087
Downstream 7939
SNR Margin(Upstream) 6.0
SNR Margin(Downstream) 6.1
Line Attenuation(Upstream) 22.8
Line Attenuation(Downstream) 45.5

A Speedtest done for both showed 6.03 for ADSL2 and 6.80 for ADSL2+ (up speed 0.92 for both)

That looks like you didn't reconnect the ADSL2 link, only start up the computer having left the router on overnight .

Swap back to ADSL2 and see .

I'm away till the evening now, but if it is still worse than ADSL2+, tick ADSL2+, ADSL2 and G.DMT. Reconnect it and that's it

If it is better on ADSL2, tick ADSL2 and G.DMT, but not ADSL2+.

The reason for ticking the two or three is in case you get a line fault. It can then train down to one of the lower ones if necessary.

I now changed it back to ADSL2:

ADSL Status
Parameters
DSP Firmware Version A2pB025f.d22k
DMT Status No Defect
Operational Mode ADSL2
Upstream 1080
Downstream 7539
SNR Margin(Upstream) 6.3
SNR Margin(Downstream) 6.1
Line Attenuation(Upstream) 22.8
Line Attenuation(Downstream) 42.5

Speedtest gave 6.46 down.

I'm surmising that you'll say that ADSL2+ ticked (plus those that you advise) is where to set it, so will do that.

This is the result (left AnnexM unticked):

ADSL Status (changed back to ADSL2+/ADSL2/GDMT)
Parameters
DSP Firmware Version A2pB025f.d22k
DMT Status No Defect
Operational Mode ADSL2+ (and ADSL2+ & G.DMT)
Upstream 1087
Downstream 7895
SNR Margin(Upstream) 6.4
SNR Margin(Downstream) 6.3
Line Attenuation(Upstream) 22.8
Line Attenuation(Downstream) 45.5

A Speedtest showed 6.76 down.

Yep. Clearly that's best for that line . It's also at about the best that anyone on 45.5dB attenuation gets. The fiddling with ADSL2 was just in case you could get a bit more, because as you can see the attenuation on ADSL2 is lower. It was unlikely, but worth a try.

Good luck now .

Thanks for all the help.
It was worth trying

What causes the 45.5db ...line length?

I see the SNR down is currently 4.6 for the time being.

Do I forget about the router trying to achieve 1500MTU - I see it trying numerous times again today while doing those changes ...would it make any difference anyway?

A Speedtest just done is 6.8/.92 so still a bit better than before and double on the upload speed.

I'll see if remains nice and stable ...if not, I can always go to FTTC

I've forgotten if you have said what version of Windows you are using. What is it please, or are you on a Mac?

It's Windows 7 Pro 64bit

Just an update - the connection has now been completely sound for 8 days with very little speed variation - usually 6.7 down .92 up

The first sign of the new TR101 info first appeared in my connection info in the early hours of Dec 12th, and although a new router was connected later that day, that never changed despite the new router giving a better sync speed and none of the disconnects I'd been getting for some weeks beforehand. (combination of router and internal wiring problems. The new wiring and master socket were done on Dec 29th, and earlier this month I upgraded to ADSL2+)
But, today the TR101 info has been updated:

Upstream Downstream Sync Rate BRAS Profile Interleave Sync Date
1087 6965 7895 TR101 Auto 19 Jan-2012 09:30
416 4573 5184 TR101 Auto 12-Dec-201 05:29
0 3500 4000 adsl3500 Auto 22-Nov-2011 19:15
Your current maximum download speed is 6965Kbps.
Your current line technology is WBMC.

And the router ADSL status:

DSP Firmware Version A2pB025f.d22k
DMT Status No Defect
Operational Mode ADSL2+
Upstream 1087
Downstream 7895
SNR Margin(Upstream) 6.4
SNR Margin(Downstream) 3.8
Line Attenuation(Upstream) 22.8
Line Attenuation(Downstream) 45.5

It's definitely better than it was!

Just spotted that the 6965 figure in the TR101 line is the BT IP Profile. What does the Current line speed in your PN Portal say? 6900?
