Slow broadband on the Smallbrook exchange.

Hi guys,

 

This is the first time I have had broadband from BT and I can't really say I'm impressed. Having spoken to BT India several times they simply refuse to fix the problem. Promising call backs that never happen, sending engineers that simply say it's a problem of oversubscription. The speed is reasonable about 7am in the morning, and then by midday it's almost unusable, I don't even try to surf in the evening anymore.

 

10/11/2010 (11:11)

 

 Download speedachieved during the test was - 906 Kbps
 For your connection, the acceptable range of speeds is 600-7150 Kbps.
 Additional Information:
 Your DSL Connection Rate :8128 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
 IP Profile for your line is - 7150 Kbps

 

 

As you can see BT claims this is acceptable.

However on the 07/11/2010

 

Download speedachieved during the test was - 444 Kbps     @19:10

 

and on the 08/11/2010

 

Download speedachieved during the test was - 418 Kbps    @00:27

 

Almost unusable. All the other stats stay as above only the throughput (download speed) changes.

 

I am almost certain that it is a problem of oversubscription. BT openreach engineers have confirmed this. However BT will not, they simply say that it must be a problem with my line. The three engineers that I have had visit claim that the line is fine?

Re: Slow broadband on the Smallbrook exchange.

Connection time shown as 2 days  have you been disconnecting the huba lot

 

Hub should be left connected and powered 24 7

I had an engineer out on Monday 08/11/2010, He turned it off whilst he did a line test. But apart from that its on 24/7.

Re: Slow broadband on the Smallbrook exchange.

After 3 visits with no result I would ask the forum mods to intervene

Re: Slow broadband on the Smallbrook exchange.

Hi, 

 

I'm a Virgin Media ADSL customer on the same exchange (Smallbrook) and having complained to VM about the slow speeds on my lime (~300kbps, but often lower, for most of the day from 4pm-2am, and a max of 1Mbps at other times), they have told me it is a problem that BT have known about for at least 6 months but won't do anything about. 

 

I only managed one successful speed test through the "official" BT website because either a) my connection was too slow, or the website timed out. This was after having asked VM for help in how to do it. The speedtester.bt.com website is frankly rubbish and VM were happy to accept my speedtest.net results.

 

There are less than 3,000 subscribers on this exchange according to BT.com/racetoinfinity - so how can it become over capacity so quickly!?

 

I copy below the email that VM sent me today:

 

2nd line have got the test results, show a connection rate of 1meg,

 

They've spoken to BT wholesale, what's happening at your exchange is that BT recognise it has a congestion issue, however because of this BT wont accept any faults for slow speeds during peak hours (between 4pm-10am). They will accept faults for slow speeds happening between 10am and 4pm if the connection rate drops to below 500kbps.

 

Not good news at all for you really! All we can really try to do is tweaks to the setup you have to try and get a bit of extra speed out of it, but 2nd line couldn't see the situation improving in the short term. With congestion issues BT normally wait until the exchange is at breaking point before they do upgrades.

 

Looking at the results you sent, we can classify you as having a degraded service, so can add a discount to try and get the price down a bit though!

 

I've thanked VM for their help and it seems I've exhausted that route so now I am appealing to BT direct.

 

I know of others in the same area, even one who lives on the same street as the exchange who gets worse speeds than myself on plusnet, and these threads on other forums to other ISPs suggest it's been a problem for a long time:

 

Eclipse in Oct 2009: http://forums.thinkbroadband.com/eclipse/3718203-frustrated-with-extremely-slow-throughput.html

Talk Talk in April 2010: http://62.24.139.3/forums/showthread.php?t=40079

 

Sadly there is no option of cable here, otherwise I'd take it in a shot.

Re: Slow broadband on the Smallbrook exchange.

Hey guys,

 

I thought I was the only one on the smallbrook exchange experiencing slowdowns between 12:00- 1:00, engineers have visited and gave the same reasons as mentioned earlier. However BT on another occasion have mentioned about the exchange receiving an exchange upgrade at the end of Nov, something about a mux upgrade I think.

 

Anyone else got further info?

Re: Slow broadband on the Smallbrook exchange.

OK Matt ..

 

Now that you have done the test it is retrievable by BT.

 

Your throughput is below the FTR, under 600kbps .... and in real terms you can ask to log a fault.

 

BT Wholesale already will be aware of the hot virtual path status of the exchange backhaul, and maybe have

 

scheduled works planned, but it'll do no harm to email the mods. and a link to this thread, for them to raise a

 

fault with BTw.     BT Forum Moderation Team <forum.moderation.team@bt.com>
