Speed drop

Rik · Oct 26, 2007, 10:17:18

Do a referral, Den.

cavillas · Oct 26, 2007, 10:24:38

I hate these people who get fasts speeds and then rub it in.

Rik · Oct 26, 2007, 10:34:09

Tell me about it, my line is degrading (I think because there's been an increase in BB connections around me, so cross-talk has gone up).

cavillas · Oct 26, 2007, 10:42:51

Do lines degrade as we get older? or is that just a fallacy?

Rik · Oct 26, 2007, 10:56:09

The ones I used as a youngster don't work any more, Alf. I'm not sure whether they've degraded or I have.

Den · Oct 30, 2007, 21:42:02

Just to rub it in further just had a speed test at 6976kbps. Who said I could not fly? O that was BT said my line would go up to 2000kbps.

Rik · Oct 30, 2007, 23:37:20

They said I'd get 3.5M. They lied!

Den · Nov 04, 2007, 17:02:26

Here we go again, alright for a couple of weeks then did a re-sync today and profile dropped straight away. It only seems to happen at weekends so I assume BT like the overtime. Sync rate now showing 6012kbps after two weeks at 8128kbps.

Rik · Nov 04, 2007, 17:10:00

What are your stats, Den? Have you done a BT speed test?

Den · Nov 04, 2007, 18:01:17

Hi Rik: a week ago BT test read

IP Profile 7150kbps DSL Connection rate 448 up and 8128 down

Actual IP throughput 6690kbps

Now reads

IP Profile 4000kbps DSL Connection rate 448 up and 6272 down

Actual IP throughput 2179 is that a drop or what?

Noise margin: 10.0dB down 25dB up
Attenuation: 41.9dB down 27dB up
Output power: 19.7dBm down 11.9dBm up

Rik · Nov 04, 2007, 18:05:38

You seem to have had a pretty low sync event, Den, somewhere below 5200k, which has dropped your profile. It will recover over the next few days, providing that you don't get more instability.

I note that your noise margin is showing as 10db, which suggests it's been raised to 9 or 12, possibly in response to a period of instability. Does the router log drops in sync? If not, as support, they will have a record of disconnections/re-connections, which may give a clue as to what is happening (and especially, when it is happening).

Den · Nov 04, 2007, 18:14:58

It's just strange that only seems to happen at a week end, the two other times were on a Friday and this time on a Sunday afternoon. The rest of the time it seems so stable and speed test are constant.

Rik · Nov 04, 2007, 18:19:43

I've always seen a pattern of weekend instability, Den, and I'm convinced that BT do work at a time when the business community will be unaffected, though I've never been able to prove it. Other possibilities, I suppose, include your neighbours doing something different at weekends. If you can log what is happening, it may be possible to resolve it, but it will need some careful record keeping on your part, or IDNet digging through the logs at their end.

Den · Nov 04, 2007, 19:10:08

I down powered my router while I had my tea. When I powered up after about 30mins.

Noise margin down is now 6dB $:-\$

drummer · Nov 04, 2007, 19:20:37

I also find Sunday afternoons the worst time for speeds, but today is the worst it's ever been. On three different speedtesters, I'm managing about 800k where my average speed is usually 6.3Mb.

My exchange is red ATM but I've always suffered slow speeds on Sunday afternoons and my DS margin usually drops to about 2 or 3.

Still, it's swings and roundabouts I suppose and not something that affects me greatly.

Thread hijack over...

Den · Nov 04, 2007, 19:35:58

That was not a hijack. Just relieved to find someone with the same odd figures as me today. For the last 2 weeks I have been recording aprox 6900kbps just now recorded about 850kbps.

Rik · Nov 05, 2007, 00:06:16

The drop in the noise margin suggests to me, Den that you re-synched at a noisy time, and that conditions had improved to give you the extra margin. Odd.

drummer · Nov 05, 2007, 02:23:55

I'm back to normal speeds now (DS margin still at 2).

My duvet is all that concerns me now though...

Den · Nov 05, 2007, 07:39:29

Ran speed test this morning came back at 5870kbps which is great but 1mb down on what I have been getting. My sync is now 7345kbps. Should I try turning off the router every hour or so until it syncs back were it used to or just leave well alone?

I'm not much good on duvet support, Drummer, but I can get Sue involved.

A single re-sync should get you some more speed, then keep an eye on the noise margin and force a re-sync when it goes above 9db.
