Re: F9/plusnet unlimated to plusnet premium speeds & traffic shaping

Just followed your advice and tested with a wired Phone into the NTE5 &  complete silence.
No pops, clicks, whistles, buzzing Smiley So that rules out any internal wiring issues ?
Yes its suspect, that the router(s) always sync around the same  6656Kbps Huh
Which is right at the top of the 3328Kbps - 6656Kbps ADSL2+ banded profile.
Maybe the change from capped 20CN on a 21CN line,  has confused some software as  the line wasn't configured to run in a fully rate adaptive mode due to already being on 21CN from an earlier change over ?Huh
BTSpeedtest
Download speedachieved during the test was - 5293 Kbps
For your connection, the acceptable range of speedsis 600-7150 Kbps.
Additional Information:
Your DSL Connection Rate :6653 Kbps(DOWN-STREAM), 1055 Kbps(UP-STREAM)
IP Profile for your line is - 5500 Kbps

Full 60min SNR stats...
Thanks f9o Smiley

Hi f9o,
This is being tested for you now, I'd expect results to be added to the ticket very shortly.

Re: F9/plusnet unlimated to plusnet premium speeds & traffic shaping

Plus These to plough through..
Upon testing the line i can see that you are really suffering from an intermittent connection that in turn is causing the exchange to lower the speed to keep you online, we will need to focus attention on these drops and in turn this should sort the speed issue's out.
For us to be able to further investigate your connection problems please answer these questions:
1. Do you lose your connection only at certain times of the day, or is it all the time? If only at certain times, please say when.
Looking at the Logs there has been patterm of sync loss between 6 & 9am However afternoon sync loss between 3 & 5pm also has taken place &  which maybe be linked to when the BT Home phone recived incomming calls
2. How long has the problem been happening and when did it start?
Became more apparent when changing to 21CN as sync speed didn't show much improvement
3. What are you doing at the time of the fault (e.g. downloading large files). Does your connection drop when idle?
Mainly idle   or light web browsing
4. When you lose your connection is sync lost on the modem/router (i.e. does the ADSL link light start flashing or does it remain solid green?)
[Complete loss of Sync both PPP & DNS connection is lost
5. Do you have any other equipment on the telephone line which may affect the service (e.g a fax machine) . Is your PSTN (voice) service working OK?
No other equipment connected to the phone line. PSTN is working & Quite line test  (17070 option 2)came back silent
6. Please connect your modem/router to the master telephone socket, leaving all other equipment disconnected. See if the problem still happens.
[Done many times & the router is always plugged into the master with the NTE5.

7. Has another modem/router been tested on your telephone line, or have you tested your modem/router on another telephone line which you know works OK?
[Yes both Trend chip &  Broadcom routers have been tested with the Master and the same results occur.

8. Have you changed the micro filter to see if this is a problem?
N/A NTE5 fitted

9. Are you on a particular website when you lose your connection?
No
10. Is the session actually disconnecting (e.g. so you have to login again), or is it reducing to almost nothing (e.g. the session stays connected, but it is hardly usable)?
[Complete loss of DNS and PPP
11. Can you reconnect again straight away, or do you have to reboot?
Nomally  DNS reconnects after 30-90 sec  PPP can take longer.
12. Do you use any other protocols and applications other than your web browser, email and FTP?
No
13. Do you get an error code when you log on again?
No
14. Have you added microfilters to all used points?
NA  NTE5 fitted
15. Is there an alarm system on the property which uses the telephone line?
No
16. Have you anything else connected to your PC besides the modem/router?
No just the NTE5

17. Please make sure that your modem/router stays switched on and plugged into the telephone socket. This will allow us to check your problem and make further tests.

Its always hard wired  into the master socket NTE5.

All answered on here which make make things easier via  copy & paste Smiley

Re: F9/plusnet unlimated to plusnet premium speeds & traffic shaping

So Looking at Downstream BIP Interface Data the line should be able to reach  a Maximum Stable Rate of 11360kbps ?
So the line is capped at only 58% of potential capacity  ( 6654= 58% of 11360)?Huh

It'll vary as long as the line drops are still present (most likely in a downward direction unfortunately). Once the fault is fixed everything should return to normal.

Re: F9/plusnet unlimated to plusnet premium speeds & traffic shaping

The line test result shows your sync speed is below the Fault Threshold Rate (which is 7952kbps), so confirms a fault.
Is your answer to question 5 complete? There are two parts to that question, the second being 'Is your PSTN (voice) service working OK?'. Isn't the answer to that 'yes' (apart from a suspicion that phone calls might interfere with the broadband connection as mentioned in reply #1)?
Could you zap the agent's full name on the fault report post - avoid offending the forum rules.

Re: F9/plusnet unlimated to plusnet premium speeds & traffic shaping

Thanks again David & Matt  Smiley
Zapped the full name, I though I'd edited  but missed that one at the end.
Changed Question 5 to:
No other equipment connected to the phone line. PSTN is working & Quite line test  (17070 option 2)came back silent
CSC said they would call this afternoon to go through the problem.

Re: F9/plusnet unlimated to plusnet premium speeds & traffic shaping

CSC just called & thanked for the detail info provided.. Smiley
Nothing obvious is jumping  out  so the fault is being pushed through to BT to come out and check things asap.
Then the connection dropped
so It looks like there is a link with incoming calls in the afternoon??  It didn't drop when the an incoming call came in this morning though. ?
There's was a hugh time lag  near 5 mins between DNS sync & getting PPP
Here the time stats..
DNS Link Information
Uptime: 0 days, 0:10:46
Modulation: G.992.5 Annex A
PPP
Type: PPPoE
Uptime: 0 days, 0:05:58

Re: F9/plusnet unlimated to plusnet premium speeds & traffic shaping

Have you watched the noise margin when you have an incoming call?
In the morning there could be enough margin that it doesn't fall to zero, in the afternoon if the noise margin is lower anyway the same decrease in margin could push you below zero and force a resync.

Re: F9/plusnet unlimated to plusnet premium speeds & traffic shaping

Hmm BT  openreach visited today.
Did the usual line test / exchange reset tests, changed the NTE5 plate & outdoor box connectors. ....
His voyager could only connect at 3meg??? So My line profile has been killed  Sad
Low sync speed remains together with the non existent higher Bit loading frequencies.
The BT engineer suggested maybe a full line retraining could help resolve any exchange software issues?
He's filling in a report & said plusnet will have access & it.
He said its up to plusnet  ,to read through the test reports  as to  give an idea on how to proceed, such as  more in depth exchange software analysis ?Huh
Here's a snap shot of the line sats ... Still below that  7952  Fault Threshold Rate.
I've now  got 3 days at 3meg and below Sad

Re: F9/plusnet unlimated to plusnet premium speeds & traffic shaping

If your IP Profile is now at 2500kbps, it should take no more than a day to rise to the 5500kbps appropriate to your current sync speed.
Taking a positive view the engineer can hardly report 'no fault found'. Roll_eyes

Re: F9/plusnet unlimated to plusnet premium speeds & traffic shaping

Thanks David  Smiley
Should I use this reduced IP profile time to switch back over to the trendchip for a day to run another direct  router stat comparison .Or just leave it alone for a few days until plusnet has access to the report.?
BT guy did phone someone to try and manually reboot some some  software (TAM ?)  after he only synced at 3000kbps.
He then went & checked the Green Box down the road, came back , did a flash test when his voyager  suggested 6000kbps as the rate.
We then loaded the speedtouch up and surprise , surprise it sync at 6654kbp.
I then loaded up the DLM tool to show him the Bit loading issues.Then showed  him the Kitz ADSL calcs for 40.5 Loop loss.
He look kind of surprised at the DLM stats software tool,  but said their is nothing more he could do & its upto Plusnet, on how to proceed..  Roll_eyes
