Strange BT issue

Hi guys..

I just got BT unlimited broadband activated and I have a slight issue the line speed is 8100kbs on the router. I did a speed test using BT speed test and it's showing line speed to the home hub 7.4meg and speed from my cpc 6.4 meg

Please post router stats & which exchange.

Sorry home hub 4 and Drumchapel exchange

Duh! I asked for the full router stats not its model. The place where you got the 8.1 Meg line speed. I'm too far away to be able to look inside your router

Sorry lol I misread will post them soon not at home at the moment

Exchange to home hub Connection speed 8.41Mb

PC speed
Download speed
7.4Mb
Upload speed
0.83Mb

These are the only stats I can get
Line state: Connected
Connection time: 0 days, 04:50:35
Downstream: 8.211 Mbps
Upstream: 1016 Kbps

There should be some figures for attenuation and noise margins which will allow people to judge whether the connection speed is in line with your line length.

What speed was estimated at the time of signup?

http://www.coolwebhome.co.uk/calc can do an assessment of the figures once you find them

Hi,

Ive just looked on BT forums and they say full stats no longer available strange..

it was from 6-10meg before on my BE connection I got 8-9meg but I know it was different equipment but I don't know why It shows 8.41Meg to the router but only 7.31Meg when downloading

8.41 Meg then allow for over heads, so best you will see is 88.2% of that, hence the 7.3 ish speeds.

Ah thanks for that thought it would have maxed my line out like when I had BE but hey ho

Some of these figrues don't seem to correlate.

Where do you get this from? Is it the IP Profile from BT Wholesale Broadband Performance Test? Please run that and then the Further Diagnostics at the bottom and copy & paste the text boxes to here.

Where these come from?

Can you get fuller router stats from How to get your router line stats - BT Home Hub?

Using the BT speedtest http://bt.custhelp.com/app/answers/detail/c/346,401,...

I cant get into any fuller stats on the HH4 I believe its locked down

1. Best Effort Test: -provides background information.

Download Speed
7.75 Mbps

0 Mbps 7.15 Mbps
Max Achievable Speed

Download speedachieved during the test was - 7.75 Mbps
For your connection, the acceptable range of speeds is 2 Mbps-7.15 Mbps.
IP Profile for your line is - 7.41 Mbps

2. Upstream Test: -provides background information.

Upload Speed
0.83 Mbps

0 Mbps 0.83 Mbps
Max Achievable Speed

Upload speed achieved during the test was - 0.83Mbps
Additional Information:
Upstream Rate IP profile on your line is - 0.83 Mbps


We were unable to identify any performance problem with your service at this time.

Interesting! That's a BT Retail speedtest that I'm not familiar with. It only gives full results for BTr BB customers only. Peeps here are more familiar with the BT Wholesale speedtest, which works on all BTw lines, whose link I gave you and you have now run.

W/out the attenuation & NM figures we cannot suggest what you should be getting..

You can't get those figures from a HH4.

That's a neat way for BT to hide that your line is underperforming.

YES, you can get these from home hub4, im on adsl2 connection with homehub4 and here are my stats

08:13:18, 19 Jul. (1032304.400000) ETHoA is up - VPI: 0, VCI:35
08:13:18, 19 Jul. (1032304.400000) DSL is up
08:13:17, 19 Jul. (1032303.370000) DSL noise margin: 5.90 dB upstream, 3.00 dB downstream
08:13:16, 19 Jul. (1032302.460000) DSL line rate: 1243 Kbps upstream, 20932 Kbps downstream

if the person with the speed problem wants to check his margins they are done by
going to homehub settings page
click trouble shooting top right
click event log
select category WAN
scroll down list till he sees the connection date he wants,

i have been with BT since leaving BE/o2 on the 5th July 2013 and my router has rebooted and resynced 4 times, im on the lowest margin now 3dB that i was on with BE and the speed is as good, just waiting for fibre in 1 months time.

How about attenuation?

Shouldn't VCI be 38?

In reply to a post by MrSaffron:

How about attenuation?

can`t see it anywhere on the logs, this is the full wan listing from one page, no where does it say, unsure why i got so many disconnects as my BE line never kept dropping like this does, but it dont affect speed

Yeah, BT use 38 unless they've changed it recently.

HI guys I got it thanks to idmanager

Not really! As was pointed out, it lacks the attenuation, the principal parameter that determines your top speed.

Yea damn.. Its getting more and more closer to my max speed with BE so can't complain too much lol

Now if you could remember your stats on Be or find them posted on TBB, that would be a good start.

45db down number thats in my head just now sound about right?

Sounds a bit too high. 45dB is good for about 7.2 Mag sync speed and you would never have got the 10 Meg you said earlier that you once got on Be.

Your speeds are more consistent with a 41dB attn, but it's in the right ballpark.

I did say that yea 9-10 at a push that was when i made my line a 3db noise margin but caused drop outs

What I dont get is my neighbor gets 10-11 meg with there sky broadband

If your router allows it you might try setting the ADSL Mode to ADSL2 (G992.3) for a faster speed.

Can you obtain his stats?

yea I will give you a PM tomorrow if thats ok as I cannot get them to then ?

OK

Your neighbour has got about the same attenuation as I guessed for you.

However his line is performing well above par for some reason. I would have predicted 9 Meg rather than the 11.5 Meg that it is.
