Broadband speed after phoneline fault fixed.

How long does it take for broadband to get back up to speed after a phoneline fault has been resolved?
Our phone fault has just been fixed after being out for more than a week. The broadband remained connected but cripplingly slow. Now the phone is back the bb is slightly better but nothing like it's old speed.
I appreciate that it may take a while but any idea how long?
Thanks.

please can you post the adsl stats from your router you may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or if HH4/5 then go to troubleshooting then logs and you are looking for 2 line together when hub last connected to internet and they will show your connection speed and noise margin or if netgear enter 192.168.0.1). Then run btspeedtester (MAC users may have problems). when first test completes then run diagnostic test and post the results ( do not reset the router).
are you connected directly via a filter to the NTE5 master or test socket or to somewhere else? Is the master the only phone socket in your home?
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
Someone may then be able to offer help/assistance/suggestions to your problem

Loss of broadband speed after line fault

We have just experienced another of our all too frequent faults on the telephone line. This has now been fixed (OpenReach repaired a couple of joints in our line) or, at least the crackling that was on the line is no longer detectable using quiet line test.
The broadband speed is now at a crawl - see summary router stats below. (router is a NetGear DGND3300). Until the problems downstream speed was about 12Mbit and upstream 0.6Mb ; noise margin was around 6db.
When we have had problems in the past the speed has always recovered within a few hours, on this occasion the speed, noise margin and attenuation haven't budged for 24+ hours. A few questions:-
1. I know that one is advised to wait up to 3 days, but should I expect a gradual improvement over this time or might it suddenly get better? (or have we still got a fault?)
2. Our exchange has been upgraded to ADSL2 since the last time we've had a fault; could this effect the way the line recovers (or not as the case may be!)?
3. The modem is not connected to the master socket at the moment. Although I doubt if this is the source of the problem; I'm tempted to do this. However this would entail disconnecting it - would the 3 day period start all over again?!

Slow Broadband after line fault fixed

Hi,
After a fault was fixed on the line two weeks ago Broadband speed has been incredibly slow - 32kBs at the most (previously it was around 400kBs)
After replacing the microfilter, resetting the router, plugging directly into the test socket I just left it alone but have seen no improvement.
Tried the quiet line test and all seems fine.
Looks like the router disconnected at least once, otherwise the connection time should be longer

Broadband speed after reconnecting the cable to th...

I was having some wall ties put in to my house and the builder split the telephone cable into the master socket. He has reconnected it via a junction box but I am still getting ridiculusly slow speeds from the exchange with the connection from the exchange -> modem running at 0.29 and my download speeds showing 0.24 and upload of 0.85.
Originally I had lost all broadband and phone connection but both are now back up and running albeit slowly. I'm presuming that this is due to the junction box connection, should the junction box have such a drastic impact on my broadband speeds?

We were unable to identify any performance problem with your service at this time.
It is possible that any problem you are currently, or had previously experienced may have been caused by traffic congestion on the Internet or by the server you were accessing responding slowly.
If you continue to encounter a problem with a specific server, please contact the administrator of that server in the first instance.
Any suggestions as I really don't want to pay in excess of £150 to get openreach to come out and fix the connection.
Thanks in advance

My upload is showing around 1.0-1.25 which is as fast as it ever was which would suggest to me that the junction box is connected up correctly otherwise I would have expected a similar degradation on the upload to that of the download.
Saying that I may be totaly wrong.

Capped (very slow) broadband speed after line repa...

Hello,
I have just had my BT line repaired due to a fault on the line 400 metres from my property. However, although the line is now fine and there is no crackling and a normal dial tone, my broadband speed seems to be capped at 273 kbps download and 811 kbps upload speeds. It won't go any faster. Before I would get roughly 2.5mb. My noise margin is 8db (it has always been quite low) and line attenuation is 58.5db (I am a fair way from the exchange).
Is there any way to manually reset the IP profile so that it goes back to normal or do I have to wait until the exchange server thinks my line is "stable"?
Any help much appreciated...
Many thanks.

Slow broadband speed after exchange upgrade

Hi,
I wonder if anyone can help. My local exchange was 'upgraded' on 14th August, immediately following that my Broadband speed has halved and never recovered, I used to get approx 7Mbps connection speed with a 5.8 ~ 6.3 Mbps down load speed. SInce then and upto now I only get a connection speed of approx 3.3Mbps with a download speed of around 2.8Mbps.
Since we have BT Vision this is now close to the limit of what it requires to work for on demand content.
I have spoken to BT Technical on a number of occasions. At first they told me it was my router (HomeHub V1) and that I could have a new one if a signed up for another 12 months. Since I doubted this and I also had a Home Hub V1.5 router I swapped to this router and it gave the same results! This was on the 7th September.
Since then I have spoken to BT Technical on a number of occasions, always this involves the same path - get asked whether I have tried different microfilter, connection to the main socket blah blah. Then they check the exchange, it comes up with a CC12 ADQ error, they ask BT Wholesale to investigate, BT Wholesale clear the error, BT technical ring back, ask me if speed is any better, tell them no, they say they will reset the line profile, this makes no difference!
If I ring again then we just go round in the same circle again.
Has anyone got any ideas or can someone sort this out, fed up of pointless phone calls at the moment!
Here are the line statistics from the BT Home Hub (V1.5) as things currently stand.:
Hope someone can help,
Thanks

Well 12 days later and still no improvement. Changed back to the homehub V1.0 (10 days ago) as the Homehub V1.5 was to unstable and kept dropping connection every few hours.
Spoke to BT technical last Sunday, they agreed to send me a new HomeHub in the end. This has now been lost / stolen during delivery - what a farce. Spoke to BT Technical again last night, went through the same sets of testing same results. Technical this time said I shouldn't have been sent a new homehub anyway as I was not in contract!
Reading through this forum and others it seems that there are a lot of people reporting speed issues (speed halving from original sync/download speed) when exchange has been upgraded to ADSL 2+ and the home hub is V1.0 or V1.5.
The tech i spoke to last night seemed to think it was the homehub but said i wouldn't get another one unless I signed a new contract. Told him there was no way I would sign a new contract when their customer service was so poor and they are unable to resolve problems.
He stated he would reset the I.P. profile. This morning download SNR has shot up to 30db (has got down to 18db) last night and sync speed was lower.
It seems to me that BT know there is an issue with HH V1.0 and V1.5 and ADSL 2+ but rather than send you a new router ask that you sign up to a new contract. This seems partly a ruse just to tie people into another 12 month contract.
My neighbours have the same set up and are experiencing the same problems since the exchange upgrade!

Slow Broadband speed after a spate of faults

Hi all,
have read many messages on here over the last few weeks and gained a lot of useful info, thanks.
My own issue started a couple months ago with a line fault which led to very poor phone and non-existant broadband, this was repaired within a few days by BT, at the same time the engineer who was very good tested the internal wiring and disconnected some very poor extensions for outside bells etc.
After he left we continued having problems and identified the problem as a faulty ADSL filter, STILL had issues with the router locking up and running extremely slowly every few hours, so router was replaced.
Now all is fine and have been connected for 3 days with no issues other then speed.
Here are the stats:
Down Speed : 2269kBps
Up Speed : 1023kBps
Attenuation (Down/Up) 38/10.5 dB
SNR Margin (down/Up) 19/4 dB
Router is now a netgear DG834v3 with dgteam firmware, connected via adsl 2+
I have phoned bt customer support and they claim to know nothing about why the speed is so low and say that it is good for my line, however I used to get 6Mb+ before the 'troubles'
Any help much appreciated,
Cheers,
Olly

Just one more thing, the SNR is 20db in the day dropping to 15db at night, it is a long overhead overhead supplying the property (1 mile +).

Very slow broadband speed following line fault

Having recently had a noisy line fault repaired I have been left with broadband that is running at a very slow speed. Having read several other posts on this forum it seems that my IP profile needs resetting in the local exchange. I am reluctant to try to explain my problem to someone in India (because I can envisage a rather lengthy call which could possibly be to no avail) so can anybody tell me if there is an alternative way to reset my IP profile.
BT's speed test results were as follows:
Download speed: 680Kbs
DSL connection rate: 2464Kbs (downstream) 448Kbs (upstream)
IP Profile: 750Kbs

Tom,
As I have posted above, we have not even seen Jim's line stats. This would make it impossible to try and establish what is actually occurring with the line and connection.
I thought about that straight after posting (actually meant to put that bit in my op ) and then spotted your post when I was going to edit my own. Was too quick on the keyboard there after watching a rather entertaining Fullham vs Chelsea match on my lappy.

SLOW BROADBAND SPEED AFTER NETWORK UPGRADE IN MY ...

On 15 Dec 10 I received an email from BT Broadband saying " congratulations the BB Network has been upgraded in my area ( Woodley, Berkshire, Exchange) I was warned I would experience reduced BB speads for up to 10 days then would see improvement. Before the upgrade I was getting an average download speed of 3670kbps, after 10 days the download speed never rose above 1000 kbps. I contacted the BT Call Center in India who confirmed that there was an external problem with my BB and sent me a new BT Home Hub2. I set the new hub up on 6th Jan 2011, however there was no improvement in down or upload speed even over the following 10 days.
On 17 jan 2011 I contacted the Call centre in India again, and it was confirmed by them that the fault was with BT retail / wholesale servers. Also since the problem had been outstanding for so long they " escalated the fault to BT Wholesale, and also booked an ADSL Engineer to come to my home on Wed 3rd Feb ( am visit). I am not sure what he will be able to achieve if the fault is external.!
Since 17 Jan the Call Centre has telephoned me every day to ask if there has been any improvement in my BB speed ( sometimes they have phoned 3 times a day! ) I am impressed with the daily contact from them however they seem powerless to get BT Wholesale to action the fault despite the fact that the fault has been escalated in priority.

Slow broadband speed after BT replaced cable to th...

Hi,
Until recently I always had a good stable broadband connection. However a couple of weeks ago it started dropping out often. This turned out to be because of a very noisy line, I rarely use the phone and when I went to check it I could hear a lot of noise on the line. I went through BT and an engineer came round this Monday and discovered the cable from outside my house had pretty much corroded away - it had likely been there 40 years! So the cable was replaced and the noise on the phone line went away (Engineer fixed it on the 11th June in the afternoon)
However during the time the line was bad my broadband (clearly in an attempt to cope with the noise) gained much higher noise margins and gradually got slower and slower, this I can understand.
The problem is now the line is repaired its still stuck at this lower speed which is really rather slow. I have read that eventually the IP profile will reset itself, but I work from home some of the time and this current speed is a real problem for me. Is there anything I can get done to get it back up to speed?

Keith, is this really the only Solution? My conneciton made it to a bit over 3 days, then for some reason its reset again
This time the upload speed has gone up some but download is unacceptable. If I have to wait another 5 days then its going to end up about 2 weeks I have had very slow broadband from BT (and who knows if it will stay up 5 days this time...), yet I boubt they will be refunding me my money for the BT vision service I can't use due to the speed issues with the BT connection. Seriously having to wait 5 days after they fix a problem is ridiculous, especially when it might reset at any point!

Slow broadband speed after noisy line repaired

I've recently had a noisy line which eventually got repaired (dirty connection on block at local poll). Since then Broadband has remained connected (good) but download speed has been none existant >250Kbps ASDL line details are as below:
I'm not getting any progress on the fault I've registered with BT on Dec 12 (says more testing is required), I keep chasing with the online support chat but keep getting the same response "we need to do some checks on the line we will get back to you in a hour or so, an then nothing". Any tips on how to get resolution of the issue speeded up?

Well the noise margin has gone up from 9.2bB to 15.4dB, which is much better, and leaves lots of room for a speed improvement.
You must be losing a lot of signal between the master socket and wherever you plug your home hub into.
Your estimated final speed should be about 7552Kbs, but you are stuck in a banded profile due to the line fault.
You are not going to get the full speed with a margin of 9.2db, but if its not practical to use the master socket, it would be worth disconnecting the bellwire while you are up in the loft, as that may help reduce any problems on your extension.
See here for instructions.
Bellwire fix.
This could help quite a bit.

Broadband still slow after line fault

Hi there,
Hope you guys can help me out
On saturday 24/11/12 I lost my broadband/phone line the whole lot, i believe due to the rather unpleasent
weather that weekend. I reported the fault, and on saturday 01/12/12 BT reported it as fixed, which was
correct, phone was working and as expected, broadband reconnected but slow.
Before the fault I would get speeds between 2000 - 4000kbps depending on time of day etc.
After the fault it was running at 572kbps and stayed here for a couple of days, although we were getting a lot of disconnects, the last one dropping the speed to 288kbps
I connected my router (its a netgear not a bt home hub) straight to the test socket and has now been stable for 3 days but no increase in speed as of yet.
My only concern is that using the BT speed tester it says the maximum speed for my connection is 0.25mbps??
Do i need to leave it connected for a couple more days? Anything else I need to try first?
Thanks
Stuart

Broadband speed drop since line fault repair

We have recently had a phone line fault fixed but after more than 3 days the broadband speed has been lower than it was during the fault and less than half its original speed.
Pre-line issue downstream was around the 16,500kbps with some drops down to 13,000kbps. The line developed a fault which started causing dc's and the phone line became noise with constant cracking and rustling sounds which turned out to be a damage connector causing water to corrode the cables, during that time when active broadband speeds dropped but while connected gave 9726kbps download and 888kbps upload, the phone line was fixed on friday the 15th of January and the phone line itself is very quiet, better than its been in maybe years, no noise that i can hear at all. However the connection dropped out during the night after the line was fixed and came back at 6652kbps down and 440kbps up, it remained at this speed for atleast 3 days then the router reconnected at 6652kbps down with 888kbps up were it remained until this morning, the router reconnected again at exactly the same speed.
I can understand it dropping originally due to the fault but has had over 72hrs connected but the speed has not increased, infact the speed is slower than with the fault which makes very little sense but i suspect is something to do with the noise margin, I include router and btw reports. Hopefully I can get some help with this.
Thanks
Jon

Great just shy of 3days connected I appear to have had another sync on the line, still no change to downloadspeed but yet again an upload speed increase, Obviously the exchange is trying to resync but it seems my download speed is stuck. This was the 1 and only connection change, should have posted the stats las tnight to show 2days 12+hrs before I went to bed

I'm with Sky, and have had very slow broadband for a while now. Above are the statistics from the test socket. Sky seem to think there is a problem with the line. I've now plugged the router into the main socket.
Any help would be appreciated.
**EDIT** My phone line is with BT, my broadband is with Sky. The problem Sky says is with the phone line it seems.

Hi Joe,
Try sticking your telephone number into this line tester page and let us know if it finds a fault. If it comes back clear, you'll need to go back to Sky as there'll be no issues with your telephone line. If it comes back with a line fault, we can get it progressed towards a fix
