What speed are you getting on 8mb bb ?

[bigmouk]

Im managing a mighty impressive 250 k/s on average :S Think that equates to about 2mb roughly. I know im a fair distance from the exchange (approx 3 mile) but that is kak ! Best speed upto now was 320 k/s (2.5mb ish)

 

[172.com]

I'm currently downloading @ 560KB/s.

3 Miles is quite far from the exchange, I wouldn't hope for much.

What are your line stats like?

 

[LadySarah]

Mine's about 2mb aswell, even though they said i would defo get 8... so annoying.

What are your line stats like?

Noise margin (dB) : 5.8
Attenuation (dB) : 53.0
Attainable download rate (kbps) : 2656

They wouldn't say that if you're on an upto 8MB line. If you lived across the road from the exchange you wouldn't even get 8.

I'm 1.5 miles from my exchange (as the crow flies), but have massive attenuation on my line, so I'm more than happy I'm getting 550KB/s plus. Just hope when I move two streets down next week I'll be able to get the same, or I'll be pissed.

Yeah attenuation is quite bad there, line noise is OK though.

Mine is:

9.0
50.0
5408

 

[bigmouk]

Basically ive got a very good 2mb line which is the best i can hope for without cable(ntl). I think the most anyone has seen from an 8mb line is around 7.0-7.1 i believe.

 

[172.com]

There was a guy on here who said he worked in this area, seemed VERY knowledgable. Might be worth searching in this forum to find him. You'll know when you find his posts, he completely owned someone else who worked for an ISP.

 

[LadySarah]

I'm still pretty disappointed with mine, just had a BT business line put into the house especially for work. Although my residential line with Telewest was loads quicker, I just needed a static IP address and they couldn't guarantee one.

Yeah I understand it wouldn't really be 8mb, but 2 is still pretty poor. At least I'm not paying for it and the boss is.

 

[RobTQ]

Well you should be happy to get 2Mb as a noise margin of 5.8 would not have even got you 1Mb on pre Max broadband. There used to be a phone number you could use to find out what the cable length is back to the exchange. But of course it should have only been used by BT eng's.

 

[172.com]

Found the thread

and it was Griff who pwn3d the guy.

Try this, see what speed you get. Newsgroups will max out my BB with blueyonder, my mate can max his 10mb line on it.

Doing this you will know if its a bad server your tryin to download from or if its your isp.


also try this http://www.adslguide.org.uk/tools/speedtest.asp

5.8 is irrelevant right now.

6db is the default snr target on a dsl max line.

at night your snr can drop due to interference.

with 53db attenuation u should have no problems achieving a faster sync rate either.

i would suggest that something is stopping you sync'ing higher. are you plugged directly into the bt master test socket? are you using extension cables? are you using decent quality filters? have you got the lastest drivers/firmware for your modem/router?

depending on your router your snr can be misreported, or your router may be able to keep a stable connection at lower db levels. my router reports between 0 and 3db at night and still keeps a stable connection.

my line details :-

Downstream Rate : 5760 Kbps
Upstream Rate : 448 Kbps
Downstream Margin : 6 db
Upstream Margin : 19 db
Downstream Line Attenuation : 53
Upstream Line Attenuation : 31

also, nobody will get 8mb throughput speeds. the highest theoretical speed possible is 7.3mb due to overheads.

 

[RobTQ]

A SNR margin of 5.8 does not look that good. Attenuation looks ok. With a distance of 3 mile from the exchange (ok, so we do not know the line length) then a 2MB ish connection speed sounds about right.

 

[Adam K]

hello????

did you read my previous post??

6db is the default SNR on a dsl max line.

at night you should expect it to drop due to interference.

nothing wrong with an SNR below 6db if the line is still remaining stable, i'd only worry about it if u are dropping sync.

 

[Munson]

I'm on 10mb NTL and I get a rock solid 1200K/s out of usenet. Remember that everything is in 1000bits, not 1024. So to work out your theory download for 8mb, its 8000/8=1000K/s

^This popped in my head last night while in bed. The socket im using must be the furthest away from the master in the house. I think there are 8 BT sockets in the house, basically every room. I think that might be the problem.

I'm 2.3km from the exchange (thought it was a lot more!)

Great site ..

[Aberclio182]

got the same prob as you bigmouk, i am on adsl max 8 mb but am only get 1.2mb or something. says i should get about 3.5mbs. think its an isp problem? i am about 1.8km from the exchange

 

[bigmouk]

I've still been using my old ntl broadband (runs out in a couple of weeks but dont have any limits) but im going to try the following on the new 8mb line ...

1. Connect the router directly into the master BT socket.
2. Put any BT phones in the house on an ADSL filter adapter.
3. Leave it for 7-14 days before testing speeds (believe it can take this long the line speed to settle down ?)

 

[McBunny]

im 820 meters from my exchange aparantly

 

[Griff]

im 820 meters from my exchange aparantly

Likewise but all this is straight line distance which has absolutely no relevance on line lengths. I've seen people who can throw stones at the exchange building from their doorsteps but their line lengths have been 2km+ because of the way it's routed arround the roads.

 

[McBunny]

damn bt and the sillyness

well i must be close ish im getting 6mbit

im You are around 1.29 kilometres from your exchange (as the crow flies).

i have 8mb adsl, and i usually top out at roughly 690kbs on a quick server.

Your attenuation isn't great (upstream is shite, downstream isn't brilliant) but I would have thought you would have got better speeds than that.

Have you tried the master socket and then getting the line stats?

that just a case of plugging the router into the main phone box yeah? and taking those stats off that. or is there another way to get the stats?

 

[sn00p]

Yes, just take the router down to the main box and repeat what you just did. At least then you'll be able to see the effects of the internal wiring in your house.

 

[clio172cup20]

10mb here 1.4mb/sec

well my wanker of a dad did it, so prob totally piss lol! will try it when i get home.

 

[Adam K]

this issue here is the 17db snr.

it's highly likely that because of poor internal wiring, the BT DLM has upped your SNR target ridiculously high. when you first got DSL MAX were you having disconnection issues?

edit - just to add, i always thought that DLM could only apply a 15db snr target maximum, so if that is correct then have you had an issue raised with BT to have your SNR altered manually at any point?

He's also on the fast path, if he'd had a lot of disconnections I'd expect him to be on the interleaved path as well. The 17db level is very odd. :S

 

[Lagerlout]

I'm 300 metres from my exchange and I only get 2Mb on an 8Mb line. Having an ongoing battle with BT.

 

[Lagerlout]

Where do you get all teh snr info from?

 

[Griff]

Where do you get all teh snr info from?

Depends what hardware you're using. Most routers will show this info in the settings/admin area and some modems can show the info albeit in a round about way.

 

[Lagerlout]

Ahh right. Well I used to use a Netgear modem/router.... BT said that the reason I wasn't getting my full bandwidth was because of that. So I switched to the BT hub and quite frankly it's the biggest heap of shite I've ever had the misfortune to use. Truly shocking.

 

[Adam K]

nope, i wouldn't agree with that statement.

now he has 17db snr his line will be uber stable and there would be no need for interleaving to be enabled if he is getting no errors.

give this a go : http://test.speedtester.bt.com:50301/

that is the new BT speedtester which isn't for general public release yet.

it will give you your bras profile when it gives you your results and you will be able to see if you have a stuck bras @ 2mb.
