Very poor service in the Docklands (Canary Wharf /...

Hi, This is my first post, firstly, i'd like to say, I have a degree in Computer Science, and over 10 years experience in the Internet, Networking and Software Development. So i'm not looking for answers like "turn it off and on again" or "there are many factors that can affect the speed of your line..." etc... Sorry if this sounds a bit harsh but I just want a good response.
So, here comes my rant...
I am connected to the Poplar exchange, which is between 1 and 2 miles away worst case. The block of flats I live in is directly connected to the exchange without passing through a street cabinet.
Before signing up to BT I was aware of issues in the docklands with connectivity such as :
- LLU providers being over-subscribed
- Syncing at low speeds and having terrible line stats
- Lack of BT Infinity in many areas, and the fact that my building may not get it for a while (due to a limitation on no VDSL from direct-exchange connected lines currently?).
Therefor, I signed up with BT on the Option 3 package... Hoping that, due to their reputation and likely superior infrastructure, they would not be too-oversubscribed and would constantly improve their bandwidth offering at the exchange as the number of connected lines increased.... Maybe I was wrong.
I sync at around 3mb which is what I kind of expected... this is due to bad line stats... which could be down to a million things... I don't mind 3mb, its just about good enough for iPlayer, emails, etc etc.
However... even though i'm synced at 3mb, I seem to only be able to reach a max of around 0.3mb of throughput most of the time... i've tried opening multiple connections to multiple servers over multiple protocols simultaneously to get around any shaping etc... but this has no great effect on the speed... which would lead me to believe there just isn't enough bandwidth available on the backbone...
Somethings (albeit very rarely) however, I am able to acheive the profile of the synced speed. As I say... this is kinda rare.
To add insult to injury, i'm typing this email using 3g "broadband" as my BT line was too slow at loading the rich text editor used to make this post... I'm also staring at the Data Center, 30 meters away, that holds servers I own and each with over a gbit of connectivity, the irony.
So a few questions...:
1. Is BT planning to increase the bandwidth allocated on their oversubscribed exchange? So that, users in this area can actually acheive near to their sync speed?
2. Is BT planning to improve things end to end so that my line stats improve to close to what they should be, given the distance from the exchange etc.
3. The one i'd really like an answer on: Is BT infinity actually going to happen for me? the exchange is enabled... No one can give a real answer on this.. and I'd like one as a customer, even a "YES it will happen within a year" will be fine. If not.. are there any planned alternatives in the near (1 year or less) future?
4. I heard there are many people experiencing the same, sync doesn't match anywhere near real-life throughput issue... any action to be taken on this BT?
Please BT could you handle this query properly and not just give me a text-book answer as thats really not what i'm looking for.

  • BT infinity very poor service - what steps to canc...

    Any one advise How I can cancel, without penalty, due to poor service?
    I had BT Infinity installed end of January 2014 it was fine stable and running at around 65-68mbps until half way through May.
    Then speed dropped to 19mbps but worse the connection would repeatedly drop staying up for no more than 5 minutes at a time and taking 10 or more attempts to reconnect. Checking the logs on Hub 5 often it would reconnect over 100 times a day.
    I've had and engineer visit once a week now, because thats all India helpdesk can arrange, for over 2 months and each one treats the visit as if it's the first time. All they can do is check my equipment is OK which they all say is fine. If had the line moved to a different card in the street box. I've had 2 replacement Hub 5's.
    Eventually in talking to one of the engineers, some are more clued up than others, I heard about RAIN engineers so I practically had to force India support to instigate this. They say they have put this in process but can't seem to report back to me anything from this. I finally got speed up to 30mbps but the connection is still unstable and as of my last call I have yet another engineer to wait in for on Monday (this will be about the 10th time I've wasted half a day!). I know full well and on site engineer can do absolutely nothing but reset the line speed which with the insatbility will drop again. So I've had enough I've been paying for the top package "unlimited data" at a significant price for a service I haven't had for over 2 months and I just want to cancel becuase of this and get a refund for poor service over that time. Every time I try to raise this with India I just get fobbed off as they really have no idea what they are doing and probably don't have the authority to handle this but BT provides no other obvious way to talk to some who can take this request to cancel seriously! Does anyone know who and where I can call, email or write to to get this usless service cancelled?

  • Very poor speed and the poor customer service is w...

    Good News - infinity will be connected to my area by the end of next month
    Bad News - My connection speed is now .283Mb instead of the 6-7Mb that it has been until a week ago. So I ring bangalore and get fobbed of over and over again. They then offer me a new hub as my N600 "is not compatible" very funny!! Well the hub never arrives. 
    I phone the cancellation line which agrees to send out another hub as my cancellation fee is nearly £130, so lets see if this one turns up. I've checked the N600 and filter and all is fine. An external line check is clear so it must be at the exchange. 
    Therefore if you have had to make room at the exchange to connect up the fibre optic tell me and I'll accept it don't just try and fob me off with rubbish..
    Totally **bleep** off

    welcome to the BT community forum where customers help customers and only BT employees are the forum mods
    in order for the forum members to help please can you post the adsl stats from your router , if netgear enter 192.168.0.1 the router status and then show statistic and 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
    if your exchnage is being upgraded to fibre that will not affect your adsl connection
    Someone may then be able to offer help/assistance/suggestions to your problem

  • Poor service and the saga of the Home Hub 2.0

    Since upgrading to Total broadband 3 earlier this year, I've had problems with the Home Hub 2.0 (type a).  It keeps locking up/crashing.  Its the home hub rather than the broadband connection, which when used with a Linksys modem router works fine.  
    I've run through usual fault finding and rectification - hard reset, plugging into test socket, countless line tests.  of course trying to get BT call centre staff to understand its the home hub thats playing up/at fault, not the connection, is like banging ones head against a very hard wall.  For a piece of equipment less than a year old it should work without problem.  And I was tempted to go to PC world and buy a replacement modem, but decided to preserve with  BT's 'help' desk.
    Over the past 3 or 4 months I've probably made one help desk call about the same issue each month.  Have to repeat myself time and time again and get fobbed off with another excuse, or promise of call back.
    Eventually got through to a supervisor - after insisting when a call log was closed and marked 'resolved' when we were still having the problems and hadn't had a call back.  Repeated my issues for the 4th or so time, went through what I had done to date (restore to factory settings, checking its logs, etc etc)  he finally consented to send a replacement home hub.
    I get an email telling me it would be delivered on the 6th before 6pm.  But of course it wasn't.  And I did as the email said, and tried to phone the number to say it hadn't arrived only to get an answer phone message saying the help desk was shut.
    So wasted my lunch break today on the phone to BT trying to find out where it was, only to learn that BT had posted it to a previous address which I haven't lived at for 4 years.  Well done BT, it takes real skill to be that rubbish.
    Fingers crossed another new one is on its way to the right address.
    I have however a couple of questions, which as I can't face phoning the call centre again I thought I'd post on here:
    1) How on earth did BT manage to send  the replacement home hub it to the wrong address?  Especially since the original one was sent to the correct address & my delivery address is set  correctly on the web portal and the agent handling the call confirmed the address? - and what are you going to do to ensure it doesn't happen again (dare I mention data protection - as the home hub pack presumably has some personal details on it..)
    2) In the final call today I was asked for my date of birth and mothers maiden name so they could add it to the account - afterwards having not been asked by BT for this before on countless calls  I wondered is this standard practice - or should I now be worried?
    3) How do you have a sensible discussion with someone - preferably in the UK - about the customer experience?  As mine as has been rubbish (you might be able to tell from the tone of this post), and I'm regretting ever having upgraded and wishing I had instead gone to another broadband provider.
    4) Given that issues with certain models of home hubs seem to be known issues (at least to google) why do the call centre agents always focus on the broadband connection -(typical conversation with an  Agent "..so your connection keeps dropping", Me: "No the connection is fine.  The home hub has crashed again". Agent "So your connection has dropped"? and on and on) rather than actually listening to the customer. (Can you reset it - yes already have, several times  and so on)
    Any answers from a moderator would be welcome.
     I am actually happy with BT's  broadband product, and don't want to have to go through the hassle of changing provider, I'm just disgruntled at how bad the home hub has been, and how poor the customer service has been.
    Thanks.

    Hi EKandrew,
    To be honest I have not heard of the hub locking up before.  The questions you have been asked by our helpdesk are aimed specifically at your connection as most problems tend to occur here, either with slow speed or hub drops etc.
    Could you be more specific in how the hub locks/crashes? What do you notice when this happens? What way do you have your connection set up?
    As much info as possible would help
    In answer to your questions:
    1/ Sometimes we have an old address still on your account and this has not been updated for packages/correspondance.
    2/ Nothing to worry about, we ask these questions for additional security.  If you have quoted your account number previously this is normally enough for most things however the advisor probably just noticed we didnt have this info on file.
    4/ As above, this is not a common problem and most issues that come to us are to do with your connection.
    Thx

  • Macbook (mid 2012, 9,2) has very poor performance since the day I bought it (less than 2 months ago)

    Problem description:
    My macbook is extremely slow since the day I bought it (which was less than 2 months ago)…Came preinstalled with Mavericks and 4GB of RAM. Upgraded it to 16GB hoping that would help, but that did very little…then upgraded to Yosemite. That just made it worse. Formatted the whole thing and installed clean Yosemite. Still, every time I right click, I get the rainbow loading icon and it hangs. Every time I open any file, or click any app, it hangs for a few seconds, again with a loading icon. Every time I play a song on iTunes or even VLC for that matter, it stops multiple times, every few seconds. Feels like it’s “buffering” while I’m playing a song off my hard drive. It’s been bothering me for too long now…Any idea what the issue is exactly?

  • Very Poor Customer Service from Verizon

    I want to complain about the very very poor service I have received from Verizon. Since I activated my 3.0MB DSL plan in Sept. I have yet to get an upload speed greater the 0.9MB. I have called Customer Service 2 times, each time I was on the phone for 2 hours and at the end of each conversation I was told that a field service agent would be dispatched to the area because there was a problem with the out side line. I have even sent them emails and feedback, nothing. I ran their in service agent and it too showed a download speed of 0.7MB.
    Yet I am still being charged 39.99 each month. Its a New Year and I am still waiting.

    #1 Visit http://www.giganews.com/line_info.html and post up the Traceroute the page shows, if you wish. Be aware that the final hop (bottom-most line of the trace) will contain a hop with your IP address in it. Remove that line. What I'm looking for is a line that mentions "ERX" in it's name towards the end. If for some reason the trace does not complete (two lines full of Stars), keep the trace route intact.

  • Idvd: once a project is burned to dvd disc the resolution is very poor.

    I have created a project in idvd with several sub menues and images. Once I burn the project to dvd disc the resolution is very very poor. Besides the images being very pixelated, the menu screens are just as bad(pixelated), so it's not just an image quality issue. The funny thing is, when idvd is open (in the editing mode) and I play the project, everything is crystal clear. Then I burn the project, and play it in my computer to verify and the quality is terrible for both, my images and the menu and sup menues. I did import my (hi-res, average of 5mb) images into iphoto, then pulled them in to idvd from iphoto. I used a supplied template, but did change the positioning and font of the text on the menu and sub-menues. I have chosen the encoding to be 'best quality' rather than 'best performance' under the idvd preferences menu. There has to be something else I can do to get a great quality with this program.
    Thanks!

    The funny thing is, when idvd is open (in the editing mode) and I play the project, everything is crystal clear.
    iDVD's Preview function can and will lie to you. Use apple's dvd player as a more accurate indicator of what the final image (or rather disc image) will look like.
    Additinal recommendations: Use best performance for QT content 1 hr. or less and not best quality setting. This may help somewhat. Also make a disc image first from the file menu in iDVD6 and then lower the burn speed to 4x or lower in apple's disc utilities or roxio toast. Use only Verbatim or Maxell DVD-R for troubleshooting purposes only.
    Lastly, when shooting on minidv camcorders make sure not to pan too quickly. Avoid sudden movements. Use a tripod whenever possible. Make sure your subject is in focus and well lit. Use new / quality minidv tapes only.

  • CD Got Stuck and Got Very Poor Support for this issue

    I Have a mac mini Intel Duo core. This is the second time My cd is getting Stuck.
    First Time It was my mac OSX Recovery Disk. I inserted My disk and restarted the system before i got the cd loaded. The Cd Got Stuck. None of the standerd recovery procedures worked. I called up support and took the system to apple care solution They took a day to take it out.
    This Time I Inserted an audio cd during Screen saver mode (Forrest Screen Saver) and when resumed to work I found out the CD was not recognised. I have Installed the eject shortcut on the top right menu bar. When i clicked eject after a long wait Nothing happend. The Drive was listed in Utilities> Disk Utility But I was not able to Eject. When I restarted by clicking the mouse button also nothing worked. Once I have restarted I have No drives Listed.
    By Callon Customer Support I tried all trouble shooting steps again. Now I will Have to take my mac mini back to service it mak take a day to fix it.
    I think cd gets stuck then we insert the cd in screen saver mode or insert it and restart before cd is recognised. Can Some one try out these scenaios and tell me whether my diag is right?
    reg Apple support It is very poor (Compared to this dell has very good support. The are having their tech ppl coming home with all possible replasement components that might have gorn wrong trouble shoot fix the issue do replacements and leave the place compared to this apple care is just very poor ). One has to carry his mini to authorised service every time this occurs and wait untill the support ppl ejects it for me (This gives me no Option other than handing over my pc and wait without one for a day). The slot drive does not have a manual eject hole accessable to end user (Thats a cool design flaw).
    In short Apple Service is very poor all arround the world
    Mac Mini (Intel)   Mac OS X (10.4.6)  

    Siva,
    Welcome to Apple Discussions!
    You just happened to have gotten some bad support by fluke. On the whole Apple's support is rated better than Dell worldwide:
    http://forums.maccentral.com/wwwthreads/showflat.php?Cat=&Board=general&Number=6 18987
    There are a couple articles which I recommend reading:

    The latter article may not explain directly why your last couple of disks failed to eject, but if you used a non-standard disk, or one that had an adhesive label on it which suddenly got into the drive, it might have affected the ability of the drive to eject properly.
    Yes occasionally you do get bad support, and occasionally a repair is flawed, but that's why when you call AppleCare and you have a problem with a repair, I recommend you speak to customer relations. They'll set you right.

  • Very poor SMB share performance on 3TB time capsule.

    Hi,
    Is the SMB shares performance on time capsule suposed to be very poor compared to the AFP shares?
    My TC will to around 9MB/s transfers using AFP, but on SMB it will do around 1.25MB/s (varies from a few KB/s to peaks of 4MB/s).
    I tested both protocols using a ethernet cable connected from my macbook pro directly to the TC.
    This is a 3TB time capsule runing firmware 7.6.1, and I did a factory reset before my tests.
    Time machine backups were disabled during the tests.
    I need SMB for my WDTV media players.

    I would not say it is supposed to be.. but you are probably correct that it is very poor.. This issue crops up time and again,,, but not from people running Macs generally.. it is windows that is the problem.
    A few things to check.
    1. Are the names actually SMB correct?? ie short, no spaces, pure alphanumeric. Both TC name and wireless names if you use wireless.
    2. Workgroup set correctly.  ie WORKGROUP .. this probably doesn't come up with the Mac but affects most PC connections and possibly the WD TV
    3. How old is the TC? If it is an early release Gen 4, you can take it back to 7.5.2 firmware.. frankly much of the trouble was introduced with Lion.. as they changed the SAMBA setup.. I would test from the WDTV.. or a PC.. if it doesn't glitch you are doing better than the Mac can do.. ie the reading in the Mac is pure Lion Lunacy.. https://discussions.apple.com/thread/3206668?start=0&tstart=0
    One of those apple changes that shows.. they hardly test anything anymore. Do a google search for Lion SMB fix.

  • No sound or very poor one from front speakers T7900 system

    I have a T7900 system and sudenly I have no more sound or a very poor one from the front speakers (left and right). The others (central, rear and subwoofer are working fine). I tried all configurations posible and from the control panel but still no result.
    Anyone can help?

    Hi,
    Try swapping the front speakers with the others, this should tell you if the speakers are faulty. You might want to get in touch with support for further assistance on this.

  • Very poor Random IO performance of 24 HDD Mirror-2 CSV on Win2012 R2 (Solved)

    We already have a 2 separate Win2012 Mirror-2 Storage Clusters (in production) and had noted that performance was very poor.
    We were looking to upgrade to Win2012R2 and storage tiering, we wanted to understand why the storage systems were performing so poorly.  So, we have not built out a new storage cluster, with 2 nodes, 3 JBODs and 24 x2TB Seagate ES2 SAS drives.
    We have run IOMeter to measure IOPs and the numbers are very poor, regardless of the 'geometries' we choose.  Our Write IOPs results for 16KB block (this our typical DB page size) are:
    2 columns, 64KB Interleave = 1043
    2 columns, 256KB Interleave = 1176
    4 columns, 64KB Interleave = 1424
    4 columns, 256KB Interleave = 1688
    8 columns, 256KB Interleave = 1677
    We only tested Write IO because this should be the slowest/worse case IOPs values.
    We also tested each HDD individually and they range between 270 and 330 IOPs.
    By our math, the IOPs values should be in the range of 3000-3600 == 24 HDDs x IOPs/HDD div by 2 [for mirror-2], but the tested are showing values which are barely 50% of this.
    Any assistance/tips would be appreciated.

    16KB I/Os never touch the whole RAID stripe so that's why you see virtually never performance increase (I;m surprised you actually see any). Try using bigger request size to see would it make any difference. You need multiple workers and deep I/O queues.
    What are you I/O Meter settings for test except write size?
    StarWind VSAN [Virtual SAN] clusters Hyper-V without SAS, Fibre Channel, SMB 3.0 or iSCSI, uses Ethernet to mirror internally mounted SATA disks between hosts.
