Re: Speed Thread (Before and after transfer speed comparisons)

Just did another test and speed seems to be getting better considering it is Peak time just now

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

Re: Speed Thread (Before and after transfer speed comparisons)

Can try turning interleaving off and see what happens if you like, there's plenty of margin there to get an increase in speed, depends what BT have set the target SNR too and which DLM profile your line's on. It may be on a high SNR/interleaved profile. Let me know if you want me to put the change in.

Re: Speed Thread (Before and after transfer speed comparisons)

Dave
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

Re: Speed Thread (Before and after transfer speed comparisons)

Further more to the above, i read somewhere that removing the 'bell wire' from the master socket actually helps with speed as well (sorry can't remember the site right now). Is that likely to help in mine and other volunteer's cases?
See this link here: http://www.kitz.co.uk/adsl/socket.htm#ringwire
Thanks again Dave.

Re: Speed Thread (Before and after transfer speed comparisons)

Since I've gotten ADSL2+ my sync speed has gone from about 7600Kbps to 8500Kbps.
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.  Sad

Re: Speed Thread (Before and after transfer speed comparisons)

I have a Belkin N1 Vision Router (a good router but it does not show snr margin or attenuation).  After its first few days of use it settled into a very stable connection.
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.

Re: Speed Thread (Before and after transfer speed comparisons)

I've just run an old-fashion version of the BT speedtest ( Grin ;D)
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.

Re: Speed Thread (Before and after transfer speed comparisons)

Since interleaving was applied to my line on 17th December it has been stable with no disconnections.  I rebooted the router today after the line had been up for 4 days and 5 hours.  Prior to rebooting my sync speeds up/down were 855/11,847 and currently they are 855/11,603, so the settings seem to be settling down to values in this region (see stats below).  Download speeds are consistently around the 9,700 kbps mark and upload speeds 710 kbps.  I believe that my IP profile is 10,000 kbps, although I haven't been able to get a BT speed tester reading for 5 days.  It's looking very good.  Thanks to all involved at PlusNet, I hope you all have a great Christmas.

Re: Speed Thread (Before and after transfer speed comparisons)

Upgraded to WBMC today.  Smiley
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.

Re: Speed Thread (Before and after transfer speed comparisons)

Unfortunately, my line has been victimised by BT Wholesale's DLM, merely by testing other equipment.  Roll_eyes
It appears that DLM is just as 'trigger happy' on WBMC as it is on ADSL Max!  Roll_eyes
It hinders ALL objective performance testing of Customer Premises Equipment.  Angry
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.  Undecided
EDIT1: Added 'the'
EDIT2: Added ADSL Max DLM'd sync rates for before/after comparison.

Re: Speed Thread (Before and after transfer speed comparisons)

I'm not sure if www.speedtester.bt.com/ is the correct url for testing WBMC connections.
My BT IP Profile is still 7150k, but my Plusnet Broadband Speed is 2000.

Re: Speed Thread (Before and after transfer speed comparisons)

Let me go nudge things on our side to what it should be based on the sync you are getting. Give me a couple of minutes and try another speedtest.

Before:

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.
