View Full Version : Drastic drop in download speed
Hi Everyone
Following on from my thread "Drop in IP Profile", the sync speed has returned to 8128 (Max report shows increase on 19/12/07 at 13:22 and again at 15:16) and BT test has IP profile back to 7150k.
However, last night the BT test gave a download speed best effort of 117 kbps, and this morning at 09:17 it still shows a download speed of 182 kbps (actual).
This nearly beats my worst Virgin snailpace speed!
Below are the current Belkin router stats.
Downstream Upstream
Data rate 8128 448
Noise margin 11.4 22.0
Output power 15.8 11.9
Attenuation 10.0 8.0
What the hell can I do about this?:confused:
Hi
Can you post the full results from the BT test result? It may be there is still a stuck profile on their end even if it's saying 7150.
Hi James
The test site informs me that I have a 3 hour wait after the last successful test!
I assume that this is the site I should use
http://www.speedtester.bt.com/
Let me know if this is incorrect.
Thanks
Marvellous! My profile is now:
Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 1500 kbps
DSL connection rate: 448 kbps(UP-STREAM) 1920 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 1198 kbps.
What other stats are required?
My Belkin router now has these readings:
Downstream Upstream
Data rate 1920 448
Noise margin 30.2 22.0
Output power 15.7 11.9
Attenuation 10.0 8.0
There was a BT Openreach van with the guy looking down through the street service hatch across the road this morning. I asked if there was a problem at the exchange (at the end of my street) and I was having problems with my broadband; but I had the usual non committal reply.
Should I raise a ticket for this?
Well, it's clearly something interfering on the line as your data rate has just dropped by 6mb, from 8128 to 1920. Are you plugged in the BT test socket?
Latest on this.
Sorry James, but I don't have the latest type of BT socket. The master socket is in the front bedroom upstairs. See piccy below.
The Belkin was attached to a home extension kit, (the flat aluminium wired type typically sold at DIY shops. This was rigged up to an existing extension socket in a different room downstairs. By process of elimination, I found that the extension kit was knackered so that has now gone. I also bought a new Netgear DG834N Rangemaster Next modem router. This is installed in a dedicated extension socket upstairs with an ethernet cable attached to the PC downstairs.
Anyway the upsot of disconnecting the extension kit and installing the Netgear is NOT a lot of improvement!
The BT Best effort test around 14:00 today is:
Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 1500 kbps
DSL connection rate: 448 kbps(UP-STREAM) 7616 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 1045 kbps
The new Netgear stats at present are:
ADSL Link Downstream Upstream
Connection Speed 7616 kbps 448 kbps
Line Attenuation 10.0 db 7.0 db
Noise Margin 11.9 db 23.0 db
(on the Belkin I noticed that Interleaving had come on, it is set to Auto in my ADSL24 page. I can't see any mention of it in the Netgear menu).
Finally, Max reports are as follows:
Max 2272 2000 Auto 15/12/2007 16:47
Max 2272 2000 Auto 15/12/2007 16:48

Max 1728 1500 Auto 20/12/2007 12:09
Max 8128 7150 Auto 21/12/2007 13:52
Max 4544 4000 Auto 21/12/2007 14:17
Max 7392 6500 Auto 21/12/2007 14:31
Max 1728 1500 Auto 21/12/2007 16:24
Max 2848 2500 Auto 21/12/2007 16:32
Sorry that this is long winded but I sure would like to get my profile and speed back up to what it should be for a house 290 metres from the exchange!
Have a great Christmas all of you out there.:)

If your sync speed stays at 7616 kbps, your IP profile will eventually rise to 6500 kbps.
Yippee!
There is a Santa after all, my IP profile has upped itself to:
IP profile for your line is - 6500 kbps
DSL connection rate: 448 kbps(UP-STREAM) 7616 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 5489 kbps
A very Merry Christmas to you all.

Damn, I spoke too soon!

Definately a line problem as your profile is probably back to 135k (check max reports?)
Hi James
The line profile is still "As of 24/12/2007 17:50, your current IP profile is 6500 Kbps"
Netgear stats are:
ADSL Link Downstream Upstream
Connection Speed 7616 kbps 448 kbps
Line Attenuation 10.0 db 7.0 db
Noise Margin 12.1 db 23.0 db
Last night at 22:45 the download speed reached an all time low of:
Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 6500 kbps
DSL connection rate: 448 kbps(UP-STREAM) 7616 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 54 kbps
I really could do with some advice as to what my next steps should be. Do I raise a ticket?

yeah, rase a ticket.... but as its xmas, i wouldent expect much to happen untill at least thursday....
Hi Smartybones
Created a ticket this lunchtime, but did another BT test just now and I got the following:
Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 6500 kbps
DSL connection rate: 448 kbps(UP-STREAM) 7616 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 4 kbps
This test was not conclusive and further testing is required.
Please wait whilst you are redirected to undertake a second test.
You now have two choices-
1. If you wish to carry out further tests and you are competent to make changes to your ADSL system configuration, then please click on 'Continue' button.
2. If not, please close the window using 'Exit' button and contact your ISP for further assistance with these results.
I tried the second test but the first time it reported that " you appear to be logged in as bthomehub@@btbroadband.com" or something similar. I tried a few times more but I got the message server not found.
I must have the lowest download speed EVER!
You must also have a really bad line fault there! I recommend calling support as this is always quicker than a ticket for extreme cases like this.
Hello there,
I think I have the same problem here, the connection has been very very slow from 24th, here are the test results:
Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 135 kbps
DSL connection rate: 288 kbps(UP-STREAM) 416 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 36 kbps
This test was not conclusive and further testing is required.
Please wait whilst you are redirected to undertake a second test.
thanks

Your problem is not exactly the same, as you have a very low sync speed (416 kbps). Have you tried connecting your router/modem to the test socket at the back of the BT master socket?
shdosd - your problem is completely different as your's looks like a complete BT line fault with those SYNC speeds. Or a filter/sky box problem.
Hello there,
I don't have sky box here, none of the other sockets are being used.
What do you suggest I should do,pls?
I have not tried connecting my modem to the test socket yet, as we have three sockets in the apartment, they all have the same front discs, now I am gonna unscrew all of them to see which one is the master.
thanks very much

If the BT speed test gives you the same result when you're connected to the test socket, get support to log a fault with BT.
Latest on this saga:
I raised a ticket on 27/12, and BT were to do line checks.
Ref: 05021995 Reported: 28/12/2007 12:39:37 Type: End User performance problem
Date BT response More details
28/12/2007 13:59:55 An appointment for an engineer can now be made if required Diagnostics show no fault condition
Closed: N/A Conclusion: Still in progress
From the above, I assume BT are saying there is nothing wrong. Well at 14:33 on 28/12/07 I did a Speedtest.net test as follows
http://www.speedtest.net/result/216177263.png (http://www.speedtest.net)
I certainly did nothing to my setup so clearly BT must have done something.
Yesterday morning I carried out 3 tests as follows,
http://www.speedtest.net/result/216440135.png (http://www.speedtest.net)
Broadband Max gave me the following
29th December 2007 09:49:39 380 Kbps 6110 Kbps
and BT Test at 09:45 was 5733kbps.
So everything seems hunkydory! Well, not really................
This morning my speedtest.net was
http://www.speedtest.net/result/216764698.png (http://www.speedtest.net)
Broadband Max gave me 2329 down and 378 up.
I've checked the Max reports and now I discover that my profile has again dropped overnight.
As of 30/12/2007 04:02, your current IP profile is 2500 Kbps.
Just what is going on here?
If the profile has dropped, it means your line to the exchange has - because of noise or interference. Are you still in the test socket ?
Hi James
As described in post 6, I do not have an NTE5 socket. My Netgear router is fitted to an upstairs hardwired extension socket. We have the master socket in one bedroom (picture attached to post no. 6) and three dedicated extensions. The one in the other bedroom to which the Netgear is attached, and two downstairs. One has a phone attached and the other is used for the Skybox.
As explained earlier, I did have a Focus DIY extension kit running from one of the downstairs sockets to the room where the main PC is kept. This is where I had my Belkin router. When all this problem first kicked off I found out that this extension had become faulty. I have completely removed this kit, and purchased the Netgear which has been relocated upstairs, directly above the room with the main PC. An ethernet cable runs through the ceiling from the router to the main PC. A second PC is also attached via wire to the Netgear in the upstairs bedroom.
My Netgear stats at present are
ADSL Link Downstream Upstream
Connection Speed 3072 kbps 448 kbps
Line Attenuation 12.0 db 8.0 db
Noise Margin 28.3 db 16.0 db
Clearly my noise margin has changed from 12.1 down 23.0 up.
The BT fault reports page states that "An appointment for an engineer can now be made if required". I assume this is for yourselves at ADSL24 to arrange. Should I telephone support once more?
I have had very similar results not much better than dial up for weeks.

I am about 5.5 mile from the exchange as the cable is laid by the road route. Ticket approx two weeks ago even though not an ADSL24 fault.
Point being i had a stable ish 1440k 8 months ago then had to settle for 1mg top whack, now cant achieve 512k.
Nothing else connected still the same suggesting the BT line.
Boluwd - yes, it menas BT can't finda fault at their end and the next step is an engineer. Support can arrange one for a suitable day if you call them. The noise margin has changed because you are connected at a lower speed. Lower speed = more SNR and vice versa. If you reboot the router the SNR will go back to normal and the speed up.
Jon - The problem with these type of faults is that they are intermittent. Somethinf is definately causing the dropouts but it's hard to pinpoint what. All we can say is that if they are still as bad in the test socket (or master socket if you have no test socket), and you've tried another router/filters etc, then it's likely to be an external problem and should be reported as a fault to BT.
