Interleaving is on at my line. Will this make a difference if I turn it off?
Attached is my modem data as well which seems to have been reduced (downstream) since the last time I uploaded that information.
Does my BRAS profile need increasing even more perhaps? Before I signed up for this trial various sites from this forum indicated that I will be able to get much higher than 14Mbps of downstream.
Thanks again for everything
Michael

I am 90% confident that Interleaving is on on my line. It was put on as my previous address had a problematic line and that stabilised somewhat.
I can't find the area on the site that tells you whether it is on or not anymore.
If it is on, please turn it off as I am not a gamer really and I don't need it as such. I mostly use the web for surfing and email, iPlayer and since I ahev an Apple TV with Boxee on it quite a bit of audio and video streaming.
If it does not affect all the above and makes the downsteam faster then please go ahead and turn it off for me.
The extra downstream may help with the Video Streaming on Apple TV as well.
Thanks Dave
Michael

I've also been presented with a ridiculously large number of upload errors; according to my router:-
FEC Errors (Up): 4,294,967,264
CRC Errors (Up): 4,294,967,264
HEC Errors (Up): 0
These errors are accumulated in the first few seconds - and then I get no more.
I raised this issue as part of the provision of ADSL2+ ( ID: 27112413)
But the response was
Quote To ensure that the fault is not caused by internal wiring, filters or hardware, and to avoid a possible charge of £144+VAT should an engineer attend and find any of these to be the cause, we need you to complete and confirm the following testing.....
This is fine - but surely there are special testing techniques in place, specially for ADSL2+?
If I were to revert to ADSL1 my connection would run slightly slower - but it would be full speed ADSL1.
Since I'm trying to run ADSL2+, it shouldn't need a BT engineer to make it work.
BTW My router says that I'm not using channels 330 - 512.

Dropping for me.

IP profile for your line is - 4000 kbps
Actual IP throughput achieved during the test was - 3571 kbps

Previous connection reported by router
Upstream 7616; downstream 448
ADSL2+ connected two weeks ago
Initial reported connections that day:
13:45 up 17984 down 1091
13:48 up 5088 down 32
13:52 up 18292 down 999
Complete disconnection, including telephone
14:02 up 18320 down 1095
14:16 up 18308 down 1083
15:25 up 18300 down 1095
It has been running for two weeks now with no ADSL reconnection (the link to PlusNet has lost for a few minutes three times but without losing the ADSL connection). This has given me a profile of 16mb.
Speed testing at different times of the day using different internet tools has generally been showing a download speed of 7.7mb and upload of 917kb.

However, it's showing the following results:-
Quote Test Results
Test1 comprises of Best Effort Test: -provides background information.
Your DSL connection rate: 9006 kbps(DOWN-STREAM), 888 kbps(UP-STREAM)
IP profile for your line is - 6000 kbps
Actual IP throughput achieved during the test was - 5537 kbps
If you wish to discuss these results please contact your ISP.
That 6000Kbps is the same as my old ADSL1 profile and speed tests are showing around 5700Kbps.
Plusnet are showing my ADSL2 profile as 8000Kbps.
I wonder if my profile is set correctly at BT.

The attached pictures were obtained within 15 minutes of connecting.
I'll try again tomorrow - hopefully, the IP profiles will have been updated.
EDIT: Added ADSL Max sync rates for before/after comparison.

It appears that DLM is just as 'trigger happy' on WBMC as it is on ADSL Max!
It hinders ALL objective performance testing of Customer Premises Equipment.
If the effects of BTW's DLM could be reversed immediately with 1 x phone call or 1 x question in the Member Centre, I'd be happy. But previous encounters with DLM (question ID: 25879600) suggest it may be less stressful to give the business to O2.
EDIT1: Added 'the'
EDIT2: Added ADSL Max DLM'd sync rates for before/after comparison.

My BT IP Profile is still 7150k, but my Plusnet Broadband Speed is 2000.

Downstream: ~2300 Kbps
Upstream: ~390 kbps
After:
Downstream: 2603 Kbps
Upstream: 568 Kbps
Line attenuation: 61db *
Noise: 14db *
* From memory.
All in all very disappointing on longer lines.
