should i be getting more speed

hi there

i am currently with bt for bb and just wondering if i can get a better speed.

here are my line stats

Connection Speed 3200 kbps 448 kbps
Line Attenuation 40.0 db 21.0 db
Noise Margin 9.1 db 20.0 db

Three red lights from that, so yes you are not doing very well.
"Normal speed range at 40dB attenuation is 5000Kbps to 6500Kbps"

What speeds do you get using the test socket?

Yes, you should be able to 5 Meg or so with those stats. Try connectiong your router to the master socket, per:

http://www.kitz.co.uk/adsl/socket.htm

See if your sync speed improves any. It might be a ring wire or faceplate issue.

many thanks for your reply, when i take the face plate of the master socket and plug into the test socket it does not change.

i only have the one socket

is this something i can get bt to try and sort out?

also tried different router and filters , which make no difference

Does the 3200 ever vary?

As the service is working, and I presume reliable then BT or any other provider is not going to expand a lot of effort.

yes between 3200 and 3300

While it's not an exact science, you could also locate your exchange using the broadband map (throw in your postcode and enable exchange locations), and estimate the distance by road.

It won't necessarily be accurate, but it might help to confirm if your attn/snr stats are per the estimated distance.

Based on the relationship shown between upstream and downstream stats the figures look sensible, and 40dB is around 3km of copper telephone cable.

The variation in sync shows its not a locked speed. Next step would be double check you only have one socket in home, and switch off everything you can via the fuse board to reduce electrical noise and see how that helps.

I have had a look its 1.7 mile down the road

Which is around 2.75kms, which is pretty close to Andrew's estimate. You never know.

had open reach out with meaning fault sorted said itr was something to do with a "crimp", could some one please explain what that means ? now sync at 5728

Result! .

herer are my line stats at the moment

ADSL Link Downstream Upstream
Connection Speed 5728 kbps 448 kbps
Line Attenuation 40.0 db 21.0 db
Noise Margin 6.5 db 21.0 db

i now only have a variation in noise margin of only 0.4db between day and night (moving between 6.5 to 6.1 ) before the fix my variation could be as high as 7db (moving between 9 to 2 )

i have now been connect at 5728 for 21 hours as yet my ip profile as not risen from 2.5mb,(ip profile before fix) should this happen in the next couple of days or could i have i stuck ip profile?

The maximum period for the IP Profile to rise is five days.

A huge jump can cause it to rise in less than 24 hours, but less than doubling of the connection speed doesn't seem to count as huge.

I think you are looking at 2-3 days in total, so another 1-2 days now. It's highly unlikely it is stuck, and there's certainly no point in contacting support until after 5 days.

It should rise to 5Mbps profile.

Crimp - the way that two bits of wire are joined together

many thanks once the ip has risen ,

is it worth hacking the snr to bring to down by 3db ( have netgear dg834g v4). Would that likely give me an increase of 0.5mb? manyt hanks

Tweaking the SNRM should be safe, but it would be very unlikely to cause the IP Profile to rise any quicker than now. I would leave it alone for now.

If you are confident about how much your noise margin varies 24/7 then maybe try it afterwards - bearing in mind that the next IP Profile step is at 6240kbps sync, so not easily reached, and any sync speed rise increases error rates. The small increase resulting would probably take at least 4 days to raise the profile to 5500kbps.

Unless 6240kbps is reachable and stable, your optimum sync is 5696kbps, as that is the lowest that gets 5Mbps IP Profile. As you are only 32Mbps above that there is no point in trying to drop to it. ADSL Max sync goes in 32kbps steps.
