Infinity, line noise, disconnections: incorrect in...

Hi,
I've had ongoing issues with disconnections on Infinity (and prior to that, copper broadband) - we were getting dozens of disconnections a day - and I think I've found the root cause: intermittent extreme line noise, caused by badly oxidised wiring in the XNTE.
I investigated the entire circuit from faceplate to openreach side of circuit and found the problem to be a very worn connection inside our XNTE (our house is a new build from 2010, so of course we have the infamous XNTE box on the outside wall) - the wires literally fell out of the plug when I touched them.
I've rewired, the line noise has gone and my homehub5 VDSL uptime is nearly two days (its not been this stable since May!) and now I have two questions.
1) Due to the extreme disconnection/error rate, DLM has dropped our data rate to 5.8Mbps download with noise margin of 27/33. How long will it take to re-train? Could/should I request a manual reset? We should be 40Mbps (and indeed, the service ran at this speed for a short while after initial install).
2) My main question: I've read that the XNTE is phased out, and new vDSL installs require the XNTE wiring to be gel-crimped (the XNTE becoming just a simple junction) and a new NTE5 + SSFP (service specific face-plate, I guess this is the one with the filter built into it?) installed as the master socket inside the house. Should this have been done when we switched over to Infinity? Would dearly love some moderator input into this second question. If it turns out we still don't have the correct wiring for Infinity this needs to be addressed.
Thanks in advance for any advice and help.

Hi punchybda,
Welcome to the forum and thanks for posting about the problems with your line and BT Infinity.
It can take several weeks for DLM to increase the profile again as long as the connection is stable and the noise is gone but if you send in your details we should be able to organise an engineer to visit you and make sure the Infinity set up is up to standard and while he is there he can also organise for the profile to be reset.
Please use the 'contact the mods' link in my forum profile to send in your details and we'll be happy to help you with this. You can find the link by clicking on my username.

Awful broadband speed, line noise + disconnecting ...

We're experiencing very slow internet speed, as well as noise on our phone line, to the point where we can hear voices in addition to static etc. Our BB speed fluctuated from a decent IP Profile to a bad one (<500kb) and I can only assume that the noise on the line is the cause.
We've gone over the tests and phoned support, who ran a test at their end and said there was nothing wrong with the line, but when they phoned back, noticed the noise.
BT suggested an engineer call out, but we've put this off until next week ~ a friend of the family who's a qualified electrician is coming to have a look first.
We can't locate our main phone socket to rule out internal or external problems - we think its in an inaccessible part of the loft, which would be a nightmare if this is true. The electrician should be able to confirm this at least.
From my troubleshooting and a rather helpful BT support member, we both came to the conclusion that the phone line is causing the problems. This would explain the noise, and the poor IP profile that fluctuates so much (from >2500kb to 135~500).
If someone answers the phone, our broadband gets immediately cut off. Have tried different microfilters. What does this suggest?
If our master socket is in the inaccessible part of our loft, what sort of costs can we expect to get a new master socket, if this is even possible?
Thanks a lot.

when you find out, could you let me know as I have had this exact same problem for 5 months. BT cant fix it.

High amount of daily d/c's and line noise regularl...

Afternoon all, heres my problem/gripe:
I'm a regular online gamer, and i'm finding that i get anything from 8-15 disconnections from the network daily, which, as you can understand, is a lil bit frustrating. I have tried different modem/routers, and, at the moment, the HomeHub 3, although it gives slightly lower speeds than the Netgear DG834v4 I was using before, it's not bad for handling the d/c's, ports are forwarded etc for games....
    Also, i have a lot of line noise on the phoneline using the quiet test, heres my stats below. I find that if I completely unplug the filter, it settles the noise for an hour or so, then its all cruddy again. Im using the filters provided by BT. Also, the speed drops randomly, its pretty stable at the moment, but sometimes can drop as low as 0.98kbps, sending me into the dark ages, having me scrabbling around for my club and loincloth, which is annoying, as when i first moved into this house, the net was a respectable 1.4mbps, but has dropped in about three noticable stages over the 6 months since i've lived here.
     I have tried both microfilters that BT have given me, and, am unable to really get a stable line thru the test socket as it would involve metres of extension cable, which would be a pointless exercise..Oh..and the other annoyance is that every time, without fail, the landline rings...I get a disconnection.
    Apologies for the wall of text..but it's not isolated incidents, but daily, regularly..often.. and ofc, i'm a bit wary of phoning the helpdesk, as, ofc, I don't want to be taught to suck lemons, and want to eliminate any hardare error before risking the £130 callout..
   Apologies for wall of text, I have a VERY manly chest and have a lot to get off it!!!

As you can hear line noise that needs to be resolved first If you connect via the test socket and try the quiet line test socket and can still hear the noise then you need to report it to BT faults on 151 but do not mention broadband when you call as you are disconnecting when the phone rings that also implies a line problem providing you connect at the test socket and the problem is still there you will not be charged for an engineers visit

BT Infinity Lag and Disconnections when another co...

Hello, I have had BT infinity since the 28th of January and love the new found speeds I now have. However whenever my sister uses the internet for Netflix and other on-demand streaming services my connection on both my laptop and more importantly my Xbox drops out and I get disconnected.
This to me shouldn't happen especially on an infinity line. I am on Unlimited Infinity 1 + Calls as the maximum speed for my line would be just over 40Mbps so going onto Infinity 2 would have been pointless.
Information on my home setup:
All devices are connected wirelessly - NOTE - I know that a wired connection would help but this is not possible due to distance between the router and my room. Also I think this is just a cop-out answer, it shouldn't just disconnect when another person uses it even on wireless.
There is a total of 4 devices that can connect at any one time but usually only three - The Xbox, My laptop and my sister's laptop.
The disconnections happen whenever my sister uses streaming services even at 2:00am like today which is what has brought me to this forum.
Any advice and answers would be greatly appreciated.

I don't think it is just my sister's laptop causing it I think its the fact she is using things like Netflix at the same time as me playing xbox. I had thought about those Powerline Adaptor's if thats what you mean by "homeplugs", but it would require me to put an long ethernet cable through the ceiling into the room above and do it from there as there would be no other way due to the location of my router.
Would that be okay?
Do these Powerline Adaptors give the same speed and reliability as a wired connection?
There is no need to install ethernet cable with homeplugs, as that's the point of them.
The major benefit of powerline networking is that users can easily establish a network using a home's existing electrical wiring as the communication medium. There is no need to drill holes in walls or ceilings to route new wiring and, as a result, installation is quick, easy and relatively inexpensive. Powerline networking is an easily accomplished networking method for AC-powered devices, which by necessity must already be near power outlets.

Re: Intermittent phone line noise

Hi BT,
I've got internmittent line noise on my line as well. The line used to be pretty good but it has been noisy intermittently over the last few years. I think it may have started when I switched to Infinity but not 100% sure.
It doesn't happen at a specific time of day, for example,
Weds 10 June at 20:30 (approx) it was noisy - did a quiet line test and recorded it.
Thurs 11 June - no problems during the day and then some noise around 21:30
Friday 12 June, noisy during the day. At 07:48 I connected to the test socket and noise still appeared. It is crackling away now.
I have video and sound recording.
Last September we lost voice - phone dead, but Infinity still working. This was fixed by BT - a wire had come loose in a cabinet. I'm wondering if there is a dodgy connection somewhere.
Due to the intermittent nature, I'm not sure what will happen if engineer visits and lthere si no noise. I suppose I'd be charged.
Please advise.
Thanks
BM

@scottwilson1
it is standard when your report a fault requiring an engineer visit that you are advised that you may be charged if the fault/problem is found to be in your home setup or internal wiring or something in your boundary that has been damaged. you need to agree before engineer visit.
if you have used the test socket and problem exists then it is more than likely problem is outside your home and you will not be charged this may help

Time Machine External Hard Drive Disconnected Incorrectly

I have an external USB hard drive functioning for my Time Machine back-ups. I usually turn off my iMac by using the sleep function. Often, when I activate out of sleep, I get the error message that the hard drive was disconnected incorrectly (I assume this means not ejected properly). But I haven't disconnected the USB wire. I can't figure ot why I am getting this message so often. Any ideas? Thanks.

It may be that your TM drive isn't "waking up" quickly enough for Time Machine.
An improper disconnect (yes, not ejecting first) can cause directory damage to the disk. Do a +Repair Disk+ (not permissions) on your TM drive, via Disk Utility (in your Applications/Utilities folder).
Depending on your drive, one or more of the following may help:
Un-check the +Put the hard disk(s) to sleep ...+ option of System Preferences > Energy Saver.
See if it has an auto-sleep or "spin down" mode you can disable.
Check with the maker to see if there's a firmware upgrade for your model.

Line item has incorrect Dr/Cr indicator for remaining amount

Hi all,
When I tried to clear the vendor payment in T.Code F-44, there are some exchange rate differences.So I used GL account to the difference amount for the automatic posting. And also already defined the GL account in OBA1, under key KDF. But there is no posting rules to be defined. Where the Dr/Cr indicator has be defined?. Because while simulating the document I got the error "Line item has incorrect Dr/Cr indicator for remaining amount"
I need help please.

Hi,
If you have defined the GL in OBA1 - KDF. Now double click on that GL, and assign Exchange Rate Diff a/c as gain and Loss
in Valuation tab page, also define Val Loss 1 and Val Loss 2 and Balance sheet adj. 1 account also.
I hope this found useful to you.
Regards,
jigar

F5119 - Line item has incorrect Dr/Cr indicator for remaining amount

Hi Guys,
I am trying to execute F-30 transaction and for some cases I got the below message:
Message no. F5119: "Line item has incorrect Dr/Cr indicator for remaining amount"
All the posting I am posting some value on the residual items.
But this situation is so strange because occurs just some times. The account that I am posting the residual is the same.
The situation is the same, but for same cases this error happens.
Let me know if you have any idea.
Thanks

Hi Guys,
I could see that there is any relationship with the value once when I change this one the error don't ocurr.
Is there any configuration related to that? residual? % of residual?
Thanks

Number of infinity lines available in an FTTC cabi...

I'm in a "rural" area with a reasonably high housing density. I would assume interest in moving from circa 200kb to many Mbit/s will be high. A small FTTC cabinet has been installed but not commissioned. Are there only a limited number of infinity lines available in such cabs or can capacity be incread to meet demand? I'd hate to miss out due to demand having been lucky enough to be in an area getting the service......

IMHO I doubt Openreach would rush to install another larger Infinity cab to cope with any overflow... for a while if ever.
So you want to get in first. If you've registered for Infinity don't just wait to be contacted.
Check regularly using your Telephone Number (for most accurate result) in https://www.btwholesale.com/includes/adsl/main.html
Or scroll down a bit to enter your number in the BT Infinity site.
The checker showed my date had been moved to 30th Sept.... I kept checking as my cab was powered up and you could easily hear it's fans running.
Then on 1st July the checker showed Infinity was available.-

Slow speeds after transient line noise

Morning.
I've had a problem with line noise this morning that seems to have re-set the IP profile for my line (speed test attached).
Could an admin please look into this?
Many thanks in advance.
-John-
Download speed achieved during the test was - 4895 Kbps
For your connection, the acceptable range of speeds is 1000-7150 Kbps.
Additional Information:
Your DSL Connection Rate :13219 Kbps(DOWN-STREAM), 1151 Kbps(UP-STREAM)
IP Profile for your line is - 5000 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 13.36:20.65:65.99 (SBE:NBEBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.
The results of this test will vary depending on the way your ISP has decided to use these traffic classes.

Hi Waub,
Thanks for the email, I'll get back to you shortly about this, need to check a few things first.

HH5 / Infinity 2 - Frequent disconnects

Hi,
I had infinity installed back in October, and things were ticking over quite happily at first. In the last 6-8 weeks, I have been getting fairly frequent disconnects, averaging 2-3 a day, but peaking at 6-10 in a single day at its worst. From within the house, the HH looks to go offline for about 15 secs, then come back up and my connection to the internet is restored. As I work from home, this can often be more than a trivial annoyance, especially if I am working on a remote system or talking to a customer.
I cannot see any obvious cause from here. There is no apparent noise on the line, no odd devices plugged in or anything else which I think would explain this. I have included some information below which might be of use to people more knowledgeable than me. If more information is needed, just say.
Any thoughts gratly appreciated,
Thanks,
Rich

From http://www.dslchecker.bt.com/:
The following is from a ping polling tool running from a machine connected directly to the HH. It is set to ping google DNS 8.8.8.8 on a 1s frequency (sorry Google, but figured you could handle the extra load). The red block shows packet loss, lasting for 15s. At the same time, the HH also became unpingable, also reporting 100% packet loss. This is exactly the same behaviour I see each time.

Looks like the dlm as intervened and the speeds capped around that 54meg level.
Personnally I'd raise a fault & see if the line checks come back with anything that might need an openreach visit.
https://www.bt.com/consumerFaultTracking/public/faults/reporting.do?pageId=21
Also check if there is anything up locally with openreach's new checker tool.
http://www.homeandwork.openreach.co.uk/problems-with-your-phone-or-broadband/search.aspx
If the test come back with no fault found, then possibly research using a openreach modem with the hh5 or get a 3rd party non-bt all-in-one. These are the two main fixes people use on here.
You've probably noticed a few of simular threads about HH5 disconnects. For what ever reason the hh5 can be great on some lines but very very mischievous on others (including mine).
The Openreach modems do seem to calm things down and with being bt based everying just works including the tv box thingy with troublesome mulicasting suff.

BT Infinity 2 - PPPoE disconnecting

I had Infinity connected on 26 March. Home Hub 5 Type B delivered by mail ahead of time. Engineer came, installed everything, but HH5 wouldn't authenticate. Would occasionally authenticate (blue light) but then would drop out. After many calls and line tests another engineer visited on 7 April. Couldn't find any problems but gave me a Home Hub 5 Type A. HH5A maintains a connection but is dropping out with a PPPoE disconnect several times a day, however at least the HH5A recovers. Line speed is gradually decreasing, presumably due to the number of disconnects.

had similiar issue on April 11 and 12th but have just noticed more entries in logs. Is this something that we should be worried about?.

BT Infinity - line calibration and possible speed...

Hi,
We recently had BT Infinity installed (14-03-2013) and the speed has dropped significantly from 37 to about 20mb
Up load seems fairly consistent at 8mb
The engineer told us that the line calibration should only take 24hrs so I'm hoping there is an issue and that we can expect better than 20mb
We've been told to expect at least 25mb although it would be nice to get more
Can you advise how long the calibration should take and maybe check to see if everything is OK?
We have had to reset the router a couple of times
Please advise
Thank you

Solved!
Go to Solution.

You should never restart the Modem in the first 10 day period. In the first 10 days it will gather line Information then after it has enough on all levels it will decide where your line performed best at and set it at that speed. It will then continue to monitor the line forever and make adjustments. The reason why it's important that you do not disconnect the modem as the Cabinet (DLM) will not be able to make connection with the modem meaning it is recording this and will compensate by lowering the speed until it has a connection. Also turning it off suddenly can cause error bursts on top of that, so it is vital you give your line the best history that you can give it.
It will always look at previous history it has and make decisions from it. If it has bad history at the start it's very reluctant to actually improve the speed in future because it's seen it's not had good history in the past. So it will slowly rise the line speed from 12Mbps to lets say 28Mbps. It will increase it increments due to your bad line history, if it has good say you maintained connection for 90 days and you suffered from a power cut and this put your speed to 20Mbps. Over the next 5/7 days you will normally see it jump straight up back to that speed. If you have bad history it will put the speed up slower and it can take 2/3 weeks for it to actually increase the speed as well.

ADSL2+ Line Noise - Only when ANY modem/router plugged in??

Hi,My parents are suffering consistent sub1Mb/s internet speeds for several months now.Telstra land line into the house, Westnet (iinet) internet ADSL2+ account, Billion 7800 modem router.Now the primary phone socket has a DECT base station and the second wall socket has the billion and a telstra landline phone on it.There's an ADSL2 filter at each wall socket.There is noticeable noise on the line heard from either phone.. but if you disconnedt the Billion router.. the noise disappears completely!So I brought over a brand new router.. exactly the same!!!! noisy when plugged in.. silent when not.I have tried the setup with the phone (and filter) unplugged in the kitchen (primary socket) - same symptomI have tried it with the phone disconnected in the study (with and without the filter) same symptom.Have tried several replacement ADSL filters and verified they are all plugged in correctly.Have tried the Router plugged into the kitchen socket instead - same symptom..Telstra tested the line (after asking me to disconnect everything- obviously all good (as the noise is only ever present when a router is plugged in.. so recon there's no fault...So what to do!!.. Thinking of trying a third modem/router.. as IT IS ONLY NOISY WHEN A ROUTER IS PLUGGED IN.. but doubt the new unit is faulty (tried it at my house and there's no noise!!)So what is causing this?I have tried every combination of isolation I can think of.Any thoughts...AJ

Did you try swap out the filters? Just incase one of the filters is faulty?
Sounds like there might be an issue which might be for the ISP to investigate, because Telstra are only able to, and only going to check the phone line to identify the faults present, so if when the modem isn't plugged in there is no phone issue, it sounds less like a line fault and more like something else...

Network line noise and BT broadband

It's worth a mention, a pal fo mine recently "expanded" his home network, using the proprietry mains network adapters that you can buy, to use your house wiring to expand your network. His caused him a lot of problems with noise, and once disconnected problems went away. Just a heads up, if you're using them.

Powerline adaptors are controversial devices. Your friend has just discovered the reason for the controversy. They work basically by sending relatively powerful radio signals through the house wiring. It is the unwanted radiation of these signals that caused his noise problems.
The problem with these devices is that, under strictly controlled laboratory test conditions, they comply with the relevant radio interference standards, and are awarded the appropriate accreditations (CE mark, etc.). When they are installed in the average house, it is often a very different story. The wiring in every house is different, and will have different effects, sometimes drastic, in terms of radiating radio interference.
PLC (Power Line Communication) for the transport of high speed data is a technology that's pushing its luck - it works fine for low speed applications like remote meter reading, but it has a whole host of interference-related problems when used for computer networking. This is well known to the manufacturers of Powerline Adaptors, but they sell them anyway on the basis that they work in "Most" cases. Manufacturers interpretation of "Most" may differ significantly from ours, however.
If Powerline Adaptors work for you, and don't cause any problems for you or your neighbours, then OK. On the other hand, if your house wiring radiates any perceptible interference from these adaptors, dump them, and use the better alternatives - WiFi or ethernet cabling. (BT Vision decided to supply these devices as part of their package. They may have since come to regret this, given the potential for service problems and unhappy customers).
