Profile up, throughput down

[pctech]

Hi

Just a question really as am not going to put this to support as I'm migrating away on Friday but I'd noticed from the router the sync speed had stayed at 1344 for a couple of days but on speedtests I was getting around 979 Kbps or so.

I decided to 'give it a kick' by rebooting and I resynced at 1376 Kbps but throughput has dropped to 926 Kbps.

Normal or odd?

What are your router stats, Mitch?

[pctech]

Yes sorry here we are

For that sync, Mitch, your speeds are correct.

[pctech]

Cheers

Here's hoping it'll go up at some point.

[Rik]

To get a 1.25M profile, Mitch, you need to hit 1.44 or better. You're attenuation is similar to mine, but your noise margin has been pushed up to stabilise your line. What sort of wiring to do have, eg extensions, devices connected?

[pctech]

Filter is plugged directly into the socket but as I explained in my thread about the NTE5 its a little unconventional as it was fitted by electricians working for the builder I think and was originally an extension.

When the engineer came to install the extra line he looked at the cabling in the recess on the outside of the wall and said it had been looped which was illegal, I explained about the builder, he tested the connection and linked the new line to it and said it should be ok for broadband (at the time BT were just marketing the fixed rate DSL products and I could not get it because I was over the maximum distance)

Was only when extended reach was rolled out I could get anything.

[Rik]

So, no sources of noise, eg Sky box, DECT phone etc?

[pctech]

Do have a DECT phone but its not on the same line and the base is nowhere near the line equipped with DSL.

[Rik]

That was my next question.

Have you done the MW radio test?

[pctech]

No will have to borrow one from someone at work as only portable radio I have is a DAB/FM one and the one that does MW (or AM) is classed as portable but not that portable.

Socket with DECT base also has a filter on it, only socket that isn't filtered is one the alarm is connected to upstairs but that has a special faceplate on it that basically hardwires it to the line.

I'm using a Philips DECT phone thats about 3 years old.

[Rik]

The other thing to try would be a 2-Wire 2700 if you're not already using one. I can lend you one to try.

[pctech]

I have the one I bought from Q, just need to put it in.

Will do that Saturday.

[MisterW]

only socket that isn't filtered is one the alarm is connected to upstairs but that has a special faceplate on it that basically hardwires it to the line

I presume the alarm does have a filter somewhere ? it certainly needs one, maybe something like this http://www.clarity.it/telecoms/adsl_hardwired.htm

[pctech]

I cant touch it at all

[MisterW]

Did you have ADSL already when the alarm was fitted ? if so it should have a filter BUT if you got ADSL after the alarm then it's unlikely to be filtered and could well be part of the problem.

[pctech]

ADT (the alarm company) advised me not to have broadband on the same line as the alarm (I couldn't get it at the time it was fitted.

It was always my intention to have it installed when it became available so I had a second line installed and then the following year had broadband installed when extended reach was available.

The 2700 is now active on my line so will see what a difference it makes.

[MisterW]

It was always my intention to have it installed when it became available so I had a second line installed and then the following year had broadband installed when extended reach was available.

Ah!, so the alarm is on a different line to the broadband , no problem then!

Lets hope the 2700 improves things

[pctech]

Here's hoping

Just run a test on TBB and am up to 953 Kbps

Attenuation has fallen to 56.5 dB

downstream rate according to the router is now 1632 Kbps down

[Steve]

So thats with 2700 HGV Mitch? If so can you keep some before and after stats and speedtests.I am sure Q will be interested, as  if I recall correctly he was somewhat sceptical of its benefits on a long line.

[pctech]

Yes with the 2700 which has been connected since about 9 tonight.

Just nipped on to check before I go for some shut eye.

Attenuation is holding steady at 56.5 and downstream speed is also steady at 1632 and noise margin is 12 dB (BT speedtest also shows 1632)

No retrains so far according to the stats so looking very good.

The the most stable its been I think, just need my profile to increase now.

[pctech]

Just checked again.

Still steady at 1632 Kbps, att. at 56.5 dB Noise Margin 12 dB

No retrains or link failures.

TBB speed test 957 Kbps.

[Rik]

The profile will take up to 5 days to catch up, Mitch, but you will gain 250k from the 2700 as things stand. Milton Keynes loves 2700s.

[pctech]

If I can break the 1 Meg barrier and keep it there thats good enough for me.

[Rik]

It's looking hopeful. Certainly, I've never found a router that performs better on my line.
