I am currently paying for BT 8mb unlimited broadband...

However every so often the speeds will drop to almost unacceptable speeds for what I am paying. The speed can be sometimes great (7.2mb) but when it hits these low points it takes an age for the speed to recover.

I have tried phoning BT, to which they sent a guy out, who plugged in another filter, told me the line was fine and left (i did a speed test once he had left and it wasnt, it was down to around 0.5mb) but because the HomeHub was displaying 7.2mb i couldnt say anything (the speed tests told me it was 0.5 whilst the homehub said 7.2.... confusing)

Anyway I got fed up and splashed out on a new router, a netgear one, this has been fine so far, but now the speed problems are here again

Heres how my speed test went http://www.thinkbroadband.com/speedtest/results/id/118299660985578423114.html

That 'should' be 7.2mb, I just forked out 10 pound on a replacement extension cable which should arrive tommorow

But i cant help but think im being ripped off here, help? suggestions?

Usual stuff have you got anything else running in the background ?
#2
just checked out the site you quoted for the speed tests and they don't seem to be reliable on that site.

Have you tried here for your speed tests ?
http://www.speedtest.net/

Hello,
Where are you getting your speed test results from that website? That is not relable and your ROUTER will tell your REAL connection.
Sorry to here about your problem. Here are a few things you can do:

1) Check to make sure you are plugged into the the BT master socket
2) Do a speed test from [url]www.btopenworld.com/speedtest[/url]. Check the higest download speed you get. Download "Large (15 Mbytes) "
3) Take your computer/laptop near the master socket and dont use an extention cable see what happens?

4) Do not use websites for speedtest if you have a router as your router will tell you your real speed.

Im the problems contiune please report back

Good Luck

Your router will tell you your connection speed - the speed at which your router has negotiated with the exchange. Your actual traffic speed will vary depending on many things:
Congestion on the network
What you are actually downloading - Updates etc or P2P
Whether or not your ISP employs traffic shaping and throttling
There are a number of things you can do though to maximise your connection:
As h4x3r says, check your speed using a reliable speedtest - if the server doing the test is busy - it won't provide you with a true figure!

Don't expect the speed that your router quotes to be the speed you will get when downloading - I believe it's around 90% of your line speed will be your 'traffic speed'
If you must use a website speedtest, use the Namesco one - http://www.speedtest.bbmax.co.uk/
Connect to the master socket - if it's an NTE5, use the test socket behind the main faceplate - this will isolate any internal wiring that may be at fault.

The following is only for those who are confident in what they are doing:
Remove the faceplate and providing you have filters on all equipment, you can disconnect any wires in the boxes that ARE NOT numbers 2 & 5 - these are the only ones you need to have connected IF YOU ARE USING FILTERS. The additional wires can increase interference on the line and reduce your broadband signal.

Please do not go removing wires if you've no idea what you're doing!!!!

In the past on a up to 8 meg service, carrying out this procedure increased my linespeed from 1.5meg to 5.6meg!!

Do not go fiddling with the BT side of the main box - this is against the T&Cs and could result in hefty bills if you screw it up! - anything after the Main Box (including the faceplate for NTE5s) is yours to play with.

When in doubt - do some searches on the net for improving broadband speed & BT wiring etc - It's all there!

I'll repeat, in case anyone didn't get it:

Please do not go removing wires if you've no idea what you're doing!!!!

good luck!

DIdnt see this mentioned.

ALso to be considered, whats your contract with BT? Is it unlimited download etc?

They may have something called a fair usage policy in which they will limit your DL speed for a while if you use it too often

Yep- Although advertised as Unlimited, if you go grazy with the downloads, some ISPs can enforce the FUP and start to limit your download speeds!!;-)
#7
Yup, I've noticed mines done that :P lol
#8
I'm on BT broadband and its really poor. Apparently they limit your bandwidth at peak times! Were lookking to move
#9
I've said it before and i'll say it again:

If you're not in a cabled area, and yu can get their full LLU service (which doesn't rely on BT's network/equipment), then for me SKY has been fantastic - full 8 meg speed, no traffic shaping and a very loose policy concerning monthly usage!! all for a fiver a month!!
#10
Ok so on my router homepage the speed says 6754kbps but on the speedtest websites it says im getting 152kbs

somethings terribly wrong somewhere
#11
Massive problems on BT's Broadband network at the moment, I go to faults daily of people reporting slow download speeds yet there is nothing wrong with there line (line loss or SNR). If your testing on thinkbroadband make sure you check the port80 button (this will test http traffic). Another good way to test your speed is to download a file from ftp as BT don't seem to be throttling FTP as they seem to be HTTP. [URL="ftp://ftp.blueyonder.co.uk/"]Heres[/URL] a good ftp site to try and download from. Try a speed test at several times throughout the day (especially after midnight) see how your speed increases afer midnight (I almost 100% guarentee it). Use the BT wholesale speedtest site here this will tell you your assured rate on your line, your actual speed, and the speed BT have set you on your line. Remember BT's upto 8meg service is a rate adaptive service which means that it will give you the maximum stable rate that your line can deal with, if the exchange sees a problem with your line that could cause you to lose synch it will adapt the rate (reduce your speed) of your line to stop this happening. Like someone suggested earlier test your connection from the NTE5 master socket. If you have no joy ring up BTBB and speak to Bangalore Bob or Bangalore Betty and ask them for an Openreach engineer to visit. He'll pop along and run some tests for you and let you know if theres a problem on the line, keep him sweet with Tea and Biscuits and he'll do all he can for you.

Did you try any of the things I posted in post #5?

Your problems sound a lot like the issues I was having when I was on Virgin (using BT's network) - high line rate, but a low connection speed!

I really feel for you - I know the hell I went through for the 8 months or so from when Tiscali introduced BB max, screwing up my connection and then me transferring to Virgin and everything getting worse again! Thank god for Sky!

I'd be very tempted to have a peak behind the master socket faceplate and see how many wires are connected up....

you only need 2 & 5 connected......

Your correct that you only need 2 and 5 connected as 3 is the bell wire, and as ADSL filters have capacitors in them (which make your phones ring) and most new digital phones have there own ringers and don't need the bell wire. But I doubt that this has anything to do with the slow speed, it could. But I doubt it. If you only have the master socket in the house theres no need to look behind the face plate of the NTE5.

As mentioned previously:
'In the past on a up to 8 meg service, carrying out this procedure increased my linespeed from 1.5meg to 5.6meg!!'
Unfortunately my line profile was still sat at 2meg! - thankfully I migrate dto Sky the very next day! But it definately made a difference to me, and to lots of other people I know of!

AFAIK, BB Max really doesn't like interference on the line - having wire 3 connected (and any others that may have been connected unnecessarily) acts as an aerial for other electrical interference and radio waves which reduces the usable bandwidth for ADSL.

Disconnecting all wires other than 2 & 5 is just one method to increase line speed, but (using BT equipment) it will all depend on what your Bras profile has been set at. (Remember your 10 day training period?) Which is set according to the most stable speed your line can handle without errors (or something!) Removing any problems in your own home (interference etc) will mean you have a better case to approach BT and have your profile reset.

If you ever get things sorted you may want to look at replacing any internal extensions with some Cat5 cable and/or fitting a filtered faceplate from adslnation.co.uk

But the long and short of it is that the BT network is over subscribed at present! If you can't sort out your issues with BT, either move to a cable or LLU service or do nothing and wait for 21CN.
#15
The only problem I have had with BT broadband is that the home hub is awful and keeps disconnecting the wireless network.


Has been ok past couple of weeks though.
#16
Openreach now fit an NTE5 with a bellwire filter incorperated into it, which can prevent the previous mentioned problems with the bell wire. BT have just given free Broadband to all there permanent workforce so that ups the numbers, and all this required Bandwith for BT vision has to come from somewhere.
#17
speed test still says 123kbs whereas router page says 6.5mb

funnily enough the engineer came out yesterday and the speedtest jumped to 6.2mb, kinda convenient how its now dropped again
#18
i have a BT home hub i have the same problem

The test (s)he would of done on thier laptop checks the speed you connect to the exchange at, it also checks for Line loss, SNR and errors. Where have you been doing speedtests/ what site?

Go [URL="ftp://ftp.blueyonder.co.uk/blueyondergames/blueyondergames/battlefield1942/demo/win32/"]here[/URL] and start to download the demo.exe, that'll give you quite a good idea what your speed is.
#20
ive done 5 seperate speed tests, tried 3 different routers, 6 different ethernet cables and 3 different extension cords..... nothing works

and that demo downloads at 18.2, speedtests are saying 182, so im guessing theyre accurate

also this might mean nothing but my ping on the speedtest always seems different, one second its 65, then 84, then 135, then 48
#21
whats your router synching at?
#22
I have a homehub and can honestly say I have never had a problem with it. Speed is always really good, I work from home so use it all day and it is great
#23
my router displays this:

ADSL Firmware Version 4.01.02.00
Modem Status Connected
DownStream Connection Speed 6848 kbps
UpStream Connection Speed 448 kbps
VPI 0
VCI 38

[SIZE=2]I can't stand the homehub, just hate everything about it especially it's looks and user menu. The Business Hub is bettr looking.[/SIZE]

Can you get your SNR and Line Loss (attenuation). I'm not gonna be able to do much just curious.

Your just having slow download speeds??
#26
im using a netgear DG834

http://www.speedtest.bbmax.co.uk/results.php?t=1184791448&v=1864773

thats what every speed test from every site gives me
#27
Those speeds ain't over clever, what did the engineer say today?
#28
well when he came the speeds jumped to 5653kbps, so he said there werent no problems. I tried explaining that there were but he was adamant it was just a fluctuation, even though ive had this problem for months
#29
i'll ask again:

did you check how many wires are connected up behaind the faceplate?
#30
Use this site let me know the results. When the engineer tests your line, all he's looking for really is synch and errors. He'll check the noise, line loss on your line with his toughbook and voyager 105 and if all is well he'll sign the job off and send the data to the service provider. They don't actually do any speedtests as such. It's possible your IP profile has become stuck and needs reset, to which you'll probably have to speak to Banglore Bob or Bombay Betty to sort.
#31
Borrowed this from Skyuser.co.uk, should still work for you on BT:

Optimising your Broadband Connection
This procedure allows you to restore your existing settings or the default settings if necessary.

Download >>>this<<<

Run TCPOptimizer, accepting any security warnings (trust me this operation is 100% safe)!

Drag the slider to the maximum capable speed of your connection.

Select the Network Adapter which connects to your BB connection (ask if you need to)!

Select the Optimal settings button at the bottom of the window.

Click apply changes.

Ensure Backup is ticked.

Click OK.

Reboot to apply changes.

Run a speed test then come back and thank me!

An update on this post the default MTU setting that TCPOptimizer set for the MTU on Optimal settings is 1500 and this may well be far to big for most people so once you run Optimal settings go to the tab bar and select Largest MTU Tab and run that and you will get the correct MTU for your connection see image bellow.

http://img222.imageshack.us/img222/9017/tcpoptimizerfq2.th.jpg

Once you have the recommend MTU go back to the General Settings Tab and change the 1500 to ???? click on apply and reboot the PC. Remember to also change the MTU settings in the router [WAN Setup > MTU Size (in bytes)]to the same ones as ones that you set in TCPOptimizer

The enigneer today if neccesary would of fitted a bell wire filter or NTE2000 face plate if he suspected the bell wire was cuaing interence.

Just trying to rule everything out, all we seem to be getting from the OP is that his speedtests are poor - speedtest are poor - speedtests are poor.

From my own personal experience and from the very nice peeps at skyuser, I know there can be many reasons for poor BB speed.
As Paddy has asked previously, a full set of router stats inc attn and signal stats would help an awful lot as would the crc error reports for a busy BB session.
:thumbsup:
#34
How do i get the stats you require? If it helps nothing seems to affect my upload speed at all

and the steps you suggested didnt work :( but thanks anyway

Port Status TxPkts RxPkts Collisions Tx B/s Rx B/s Up Time
WAN PPPoA 4346 4617 0 2090 4787 00:07:27
LAN 10M/100M 15093 20673 0 5281 3836 00:16:54

ADSL Link Downstream Upstream
Connection Speed 6560 kbps 448 kbps
Line Attenuation 35 db 10 db
Noise Margin 15 db 26 db
#35
Nothing wrong with those line stats, your voice side of the line ok? No crackling or hissing?
#36
some crackling on the phone, comes and goes
#37
Did you tell the engineer this today? Thats "possibly" the source of your problems, it's likely to be High Resistance disconnection in the network. Are you fed from a pole?
#38
Im not sure, I told him but it was fine when he checked, so obviously there was no problem (this really pissed me off)
#39
If you do and I emphasise DO have a noise fault on the line report it to BT or whoever provides your phone service. Next time it's crackly ring the faults dept of your chosen telephone provider and report the fault. get them to verify the noise on the line. However if your not 100% sure that there is noise on the line don't report the fault as you may find yourself on the end of a hefty call out charge.
#40
what did the BT speedtest say your profile was set at?
