I had been having a few problems with my line for a few months which finally resulted in BT fitting new copper from the green box, and also in the junction box in my flat. But since then i have been unable to get the speeds i used to have before the problems started.
So over the last few weeks i have been trawling the net trying to find out some information to try and help me resolve the problem.
I have been monitoring my sync and noise with router stats and at around 6-30/7-30am and 6-30/7-30pm my connection seems to try and resync, this is forcing me to be stuck with a 500k profile. I used to have a 1000k profile.
I don't get a lot of errors in a 24 hour period.

Not sure what happend here but noise level of 50db on a 5km line would be nice :D

Any body gopt any ideas why i can no longer get a stable line (even though copper has been replaced), or even get speeds like i used to.
Thanks for any and all help

Hi
>> Line Attenuation: 63.5 dB
Your actually on a very long line
>> Interleave Depth: 1
I'm surprised at that - long lines normal benefit from having interleaving applied so why the DLM hasnt turned it on for your line.
That first noise spike is very strange 50dB SNR Margin!!! Ive no idea what all that is about looks more like mis-reporting unless someone else can come up with an idea.
The downwards spike at 19-15ish is more typical of a power spike - perhaps something being turned on at that time - street lighting, heating, electrical equipment either in your own home or close neighbour.
-
Hi Kitz
Thanks for the reply, Interleave was turned off at my request months ago when the line was stable at 1mb.
Yeah i though that the noise spike might have been street lights but they do not switch on until 8pm, car park lights are at around 7-45pm.
My next door neighbour does not have this problem and runs at 1 mb.
-
Like kitz said, the 50dB upwards spike is undoubtedly a reporting error, probably a routerstats glitch.. depending on the way your router displays the SNR compared to everything else. Or the router being silly and reporting 50dB??
The downwards spikes - are they when the router resyncs? As you're aware I'm sure, given the length of your line it could be anything along the length, but you'd think it would affect your neighbour too if it was strong enough to cause such an impact on your line.
It's a bit of an odd one, can you think of ANYTHING at all in your house that switches on / off at those times?
-
>> Interleave was turned off at my request months ago when the line was stable at 1mb.
ahh - that explains that one :)
>> My next door neighbour does not have this problem and runs at 1 mb.
Anything in your own home that could cause it - certainly shows all the symptoms of a "flick of the switch". heating, cooking, tv?
[edit]
Chris was posting at same time as me
-
to answer both of you, there is nothing in my house that gets switched on at these times, heating is Eco 7 and switches on a 1am, TV is on from 5pm. Cooker is never on at these times. So nothing springs to mind at the moment but i will try and see if anything springs to mind.
Actually on the middle graph was Saturday evening, there was only me in the house playing on my x-box there was nothing switched on other than the fridge/freezer, TV, X-box. But on this ocassion it caused an LOS an 9 LOF
Also on all ocassions of the noise spike, i get a large jump in SF errors.
(https://forum.kitz.co.uk/proxy.php?request=http%3A%2F%2Fi393.photobucket.com%2Falbums%2Fpp15%2FAzHudson%2FSFErrors.jpg&hash=35c5ab022ebf6d0721f22f40388531216e4cd42a)
-
>> i get a large jump in SF errors.
Again typical of some sort of electromagnetic interference. :/
Although its not typical of full blown REIN (http://www.kitz.co.uk/adsl/rein.htm), which is often when you would continue to see the errors rise whilst the offending item is switched on, this is impulse noise which occurs just whilst something is being switched on. - although I notice from the graph that errors seem to steadily accrue throughout the day.
Theres a list of common culprits on that page which were kindly provided by our "resident" Openreach engineer Ezzer whom on occasions specialises in REIN faults affecting BT lines.
-
Cheers for that Kitz
So i need to get myself a AM/MW radio that tunes as high as 617Khz, and go searching within my aprtment to find the offending item.
-
That is one way of doing it and how some people find the culprit, however in your case it may be even more tricky since rather than being continuous for a while when the offending item is switched on, yours appears to happen fairly quickly then recovers. :/
-
Cheers for the reply
That is one way of doing it
What is the other way ?
Just as i was typing this message, the error has happend at 5.46pm earlier than normal, so i went outside and there was no street lights on. So i think street lighting can be discounted.
Is it more than likely a fault with equipment within my apartment or from an outside (along the line) ?
Hudson
-
Actually on the middle graph was Saturday evening, there was only me in the house playing on my x-box there was nothing switched on other than the fridge/freezer,
fridge/freezer, can be one of the worst items for sending spikes on a system, but strange it happens at the same time each day. (unless I missed something)
-
Hi Oldfogy ;D
Yeah you were spot on that the problem happend around the same time every evening, apart from today. I walk through the front door switch the TV on ,Sky sports news as Keegan might have been peddled. Went on the net to find some more information on the keegan situation and then it resync'ed.
So not really got a clue as to what's going on.

Could be your Sky Box or your TV?

Wish i had sky, Intergrated Freeview :(
I had though that that may be the cause, but to no avail.
but i think i may have found the problem, in the car park there is bollard style car park lights See below.
http://i393.photobucket.com/albums/pp15/AzHudson/BollardLight.jpg (http://i393.photobucket.com/albums/pp15/AzHudson/BollardLight.jpg)
When i came home at about the time my noise increased tonight the below light was on and is not normally on that early.
But then again it could be anything in the below images.
http://i393.photobucket.com/albums/pp15/AzHudson/ElectricCuboard2.jpg (http://i393.photobucket.com/albums/pp15/AzHudson/ElectricCuboard2.jpg)
As you can see the BT junction box for all apartments is just below the light, but directly oppposite

I see on your 2nd picture there is a "Time Clock"
Have you checked what the time/s are set for?
(As for the last picture, I didn't know you had taken a picture of my PC wiring set-up) :lol:
-
I'm too sure what it is for. But i have already switched it off ;D
Thought it may have been for the parking/bollard lights. but they switch on via a dusk sensor.
Yeah that wiring is a leccys dream ???

Not for the lights inside stairwells or something? Maybe the car park floodlights?
-
The lights in the stair well run off PIR sensors,
The car park lights run of small sensors that are located at the middle of the post.
The timer after a bit googling is for the door entry system

I have just been looking at the BT box and noticed that a fair few wires have been trapped, especially on the bottom right corner.
http://i393.photobucket.com/albums/pp15/AzHudson/BTBox.jpg (http://i393.photobucket.com/albums/pp15/AzHudson/BTBox.jpg)
-
Yes but what sort of time is it set for?
Is it around the time of your problem/s?
With the possibly damaged BT wiring, I doubt if it would be that because of it being roughly the same time.
On the other-hand, you could also ask your neighbours if they have anything that switches on each day at that time.
-
Hi The timer is set to switch on at 8pm and off a 6.02 am, but i have now set it to the off postion.
I have been speaking to my neighbour and he is not getting any faults on his line and runs at 1mb very stable.
Regards Hudson
-
>> I have been speaking to my neighbour and he is not getting any faults on his line and runs at 1mb very stable
Is it possible that he may not have noticed it, with it being a spike?
The only reason I mention it is that mr_chris who lives in a flat, where 4 share a similar kind of set up with the electric cupboards etc.... had a problem with his connection at certain times of the day. He never got to the bottom of it - until one of them moved out and it suddenly stopped.
-
Hi Kitz
With refrence to my neigbour, he is a hardcore x-box gamer/program developer.
When i have spoke to him about this he seems rather sure that he has no problem. He did have a problem in the past but this fixed it's self about 4 months ago :o
-
Perhaps it has "unfixed" itself ? :o
-
Well have just been to see my neighbour and he switched all his normal stuff on, and so far there has been no drop in my sync speed.
I have switched the car park lights of at the main fuse box via the trip switch.
I will keep a look out to see what neighbours get in at what times and see if my sync changes around that time.
Hudson
-
Hello again, so far 9 of my 11 neighbours have all come home from work and switched all there normal stuff on that they normally would, and no resyncs so far ;D
Only 2 left to get home
-
Good luck with it and hope it brings out something!
-
Awww, my connection just resync'd about 10 mins ago. done the rounds with the neighbours but no joy.
They have turned nothing on at the time i mentioned.
Is there anything that can be done to help this problem ?
-
Have you checked all other lights?
Any fluorescent lights on the stairwells etc flickering, as this is a cause?
-
Infact, as it turns out, it's the neighbour right above me, but there attitude was thats your problem mate and shut the door in my face. >:D
Great so i doubt this will ever get resolved now.

Did you get chance to suss it out my watching who comes in or did you actually see anything? Except the neighbours door!?
-
Just as i hit the post on the comments about it not being my neigbours i could here upstairs banging around as normal !!. So i went up stairs explained the problem and asked if they had turned anything on at the time of my resync and got the thats your problem mate and the door in my face.
Might not be them, but it seems too coincadental.

I don't really know what else to suggest? I am sure kitz will be along to suggest something?
Have you tried the Radio trick?

No you have been more than helpfull, It is greatly appreciated.
I'm going to move the router to the other end of the apartment tonight away from the living spaces,there is 4 living rooms all next to each other within a relativly small area. Also the BT master socket is in the bedroom.
I currently have a 20 metre rj11 cable running to where the PC is so i could monitor the router for dropped syncs when the problem first started.

It could be the 20metre extension picking up interference if its the thin type?
-
Yeah i did have, but when the first problem started over 12 weeks ago, my ISP advised me that my router was on its way out so i bought a new router (netgear DG384pn) RJ11 cable and Filtered face plate.
The RJ11 cable is this type but longer.

Try a shorter cable via the master socket, I know it is in the bedroom?
Can you manage with wireless to monitor it?
-
Yeah once i have sorted a few things out im will set the wireless side up and move the router back into the bedroom with the rj11 cable that came in the box.
Gotta be worth a try

Always worth a try.
I had my router in the master downstairs for weeks while Tiscali moaned and complained!
Didn't get anywhere and proved my extensions are all fine in good working order :-\
-
>> got the thats your problem mate and the door in my face.
Nice! :(
>> move the router back into the bedroom
May be worth a try.. and also some other locations if possible.
Obviously I dont know the layouts of the flats.. but the fact your other neighbour did have a problem that later vanished and yours has started makes you wonder if an offending item causing the problem has been relocated.
A neighbours portable TV is something that weve had on these forums in the past that has been found to have been the culprit. A neighbours PC monitor was another that was fairly recent. However saying that both those items continued to throw out EMI whilst they were switched on which made the tracking down with the radio trick a bit easier.
Because this is happening as burst noise, then the radio isnt going to be too sucessful in being able to pick it up, since normally you walk around using the radio to hone in.. but if the noise isnt there for a continous period of time, then it makes it extremely difficult to pinpoint :/

Cheers for the help gentlemen ;D
I have now moved the router to the bedroom on a shorter RJ11 cable and i have been sync'd all day at

Power: 15.7 dBm
The power level has increased from
Noise Margin: 13.2 dB

Also on router stats, what is the diffrence between the the noise margin graph and the RX noise graph ?

No probs, nice to see the sync speed is back to normal again :)

Damn though we where getting somewhere there, but just had another resync ay the dreaded 7.30 pm.
My neighbours above me are out as well, the mystery deepens !!!!

Hmmm?
Are there any lights at all coming on at this time?
Faulty Transformers are also an issue I believe?
-
I'm getting full sync with the exchange and all lights on the router stay light, but the noise level drops to 0db and re-syncs and half the speed and a higher snr, also the power level decreases.
Current stats are.

My ISP would like to make an appointment for a BT engineer to visit again, but as the problem only happens out of hours, how likely is he to find a fault ?
Hudson
-
Excellent news, new location is hopefully further away from whatever it is. I'll keep my fingers crossed for you that things remain that way tonight.
RX (Received) is the downstream SNR Margin.
TX (Transmit) is the upstream SNR Margin.
Both are different figures and can fluctuate independently.
Not sure why youre not getting full downstream power, there are times when the dslam will attempt to turn it down to avoid crosstalk. I dont know much more than that though Im afraid.
>>> Damn though we where getting somewhere there, but just had another resync ay the dreaded 7.30 pm.
DAMN, DAMN DAMN didnt see that until I'd started my reply above... whats the new resync speed?

To be fair kitz, Jameseh did ask for me to arrange an engineer visit few weeks ago, but i have delayed setting a date because the fault only happend at night and did not fancy getting a £150 bill for a no fault call out.

Yep James and the other reps are normally pretty much on the ball. I wanted one of them to see this thread so that they know you have done absolutely everything in your power to get this sorted... and therefore not be landed with the bill.
-
Yeah got to agree, as james help sort my latency problems when i first joined them from Virgin >:D.
I have been a bit worried about getting billed by BT for a no fault, as the ticket guys just keep say.
The line tests have completed and are showing your connection to the exchange (known as sync) is set at a normal rate for your line based on your line attenutation and exchange determined maximum stable rate. Unfortunately It would appear your line is either very long or of poor quality and wont support higher speeds.
For over 7 months i was connected at a rock solid

-
Yes I fully understand your concerns about that.
Hence why I'm hoping that James or one of the others will see and pick up on this tomorrow and clarify the situation for you.
Your current sync is still within acceptable levels, but things have gone downhill due to the damn SNR spikes :/

Not to bad so i thought i would run a BT Speed Test and got the following results.
Test1 comprises of Best Effort Test: -provides background information.
Your DSL connection rate: 1248 kbps(DOWN-STREAM), 448 kbps(UP-STREAM)
IP profile for your line is - 1000 kbps
Actual IP throughput achieved during the test was - 430 kbps
The throughput is rather low for th IP Profile
Will i have to reboot the router to get the 1000kbps profile ?
Hudson
-
If the BT speedtester says that your IP profile is 1000 kbps then that's what you've got. Throughput can be a lot less than the profile for all sorts of reasons. If you use Windows, then you might need to adjust your MTU value. (http://www.kitz.co.uk/adsl/MTU2.htm)

Hi roseway
Cheers for the reply.

I have not changed the MTU since i have owned the PC (Vista Home), I used to get 1mb so i doubt it's that.
Any other ideas ?
-
You can't reach any conclusions from a single speedtest, and most of the things which affect actual throughput are not under your control anyway. I would suggest that you do a few speedtests using different testers at different times, and see if there is any pattern.
Testers which you might try are:

That does rather suggest that you are being capped by your ISP to 0.5 Mbps. I suggest that you ask them if this is the case.

Connection Rate: 1728 Kbps
Line Attenuation: 63.5 dB
Power: 16.7 dBm
He is also going to put a request into BT to go underground and find out why nearly 1Mb is being lost in less than 300m from green box to apartment.
So i just have to sit tight for a week and continue monitor the connection.

Thats a bit better! lets hope it can stay like that, and nothing happens this evening.

Fingers crossed for you.

Ahh welll, looks like the problem is here to stay.
Just had 900 crc errors and a re-sync. :(
This has got me wondering now, If im on a diffrent line then why do i still have the same problem ?

You may well have a different pair from the exchange to the DP.. but it would seem that same line is now also picking up the same interference from a local source that the old line was.
Whilst the new pair initially seemed better, the (local) noise caused by whatever it is.. is still strong enough to knock out the new line. :/

Well this weekend has been prity much the same as always, just the min it syncs to now is 1066kbs.@ 10db noise
Also i had 2 dropped connections at lunch time for around a minute each time.
>>You may well have a different pair from the exchange to the DP..
By the exchange do you mean the Green Box around the corner ? As far as im aware the new pair was a spare set from a empty apartment, back to the green box.
>>but it would seem that same line is now also picking up the same interference from a local source that the old line was.
By local do you mean within my Apartment or from my apartment back to the green box ?
Also what do bits/tone play in all this ?

BTW Kitz cheers for replying at 3.20am ???

Ok sorry about that i really should learn how to post smaller pictures :-[

>> By the exchange do you mean the Green Box around the corner ?
E side is between the exchange and the green cab. D side is between the green cab and DP (Distribution Point) which is for example the telephone pole. Drop wire is from the telephone pole to your point of entry to the home/master socket.
I suspect the interference is being picked up somewhere in or around the apartment. Since youve tested from the master socket without much difference, it looks like possibly somewhere between entering the building until it reaches your master socket.
The graphs show which frequencies are in use and which are the strongest.
A perfect line would show a healthy curve similar to you upstream one. The dips show the frequency bins were the signal is weakest and may possibly be an indication at what frequency the noise is being transmitted at.
Someone more skilled at electronics than me may be able to give a better answer.

Hi Kitz
Cheers again for the replys. Things are making slightly more sense now :)
I don't have a drop wire as every thing is underground.
Anyway the problem is still ongoing but things have switched around !!!
Now i'm getting a dropped sync at about 11.30am and re-connecting at 1728 Kbps within a few seconds , then a re-sync on the night at around 7pm with speeds droppping to around 1088 kbps.
So BT would like to visit me again, Third time lucky

Hi Kitz, Just thought i would update you on my problem.
BT have been underground, and plusnet have turned interleaving back on, and i'm getting rock solid connection with 10.2db noise and speeds of

Scrub that things are back to normal again, so i have to go through the whole process again with my ISP :no:
