Speed drop

Den · Oct 15, 2007, 13:22:04

Just ran a number of speed checks as my speed seemed to be down. All came back at 4800kbs, Ran BT test and found my Profile had dropped to 5000kbps and throughput was 4588kbps.
On checking my BT 2700HGV router I found that DSL Link retrains, Loss of framing failures, loss of signal failures, loss of margin failures all happened at 3days 3:52:30 ago. Also DSL Severely Errored Seconds at 1day 21:59:38.
I assume that this means that BT will have dropped my profile until Sync is held for 3 days. Am I right or do I have to contact Idnet. Loss of Cell Delineation at 0:32:51 (half an hour ago.

Rik · Oct 15, 2007, 14:13:53

Hi Den

These days, it takes up to 5 days for a profile to recover.

It sounds like you got hit by a burst of noise, or possibly by some exchange work.

Den · Oct 15, 2007, 16:37:40

I thought that when you had a problem and lost sync it would only drop 500kbps not 1500kbps.

Rik · Oct 15, 2007, 16:39:47

No. The way it now works is that if you've had a major speed drop, but it's an isolated incident, it recovers in less than an hour. Other speed losses take up to five days to recover. Good for a few, worse for the majority.

Den · Oct 17, 2007, 18:33:44

After the five days nothing changed, phoned idnet and Miriam said she would contact BT. About an hour later she rang back and left a message to say BT would raise my profile which they did but only by 500 to 5500kbps. This was because my sync was about 6000kbps. She suggested I rebooted my modem and leave it for about 5 mins. This I did and my sync on the BT 2700HGV is now on 7895kbps so I'm waiting for BT to adjust over the next few days. I assume this will take my profile back up to 6500kbps but it would be nice to think it might go to 7000kbps. Once again idnet came up with the goods.

Rik · Oct 17, 2007, 18:35:54

That sync should get you 6500, but not 7000. Still you're doing better than me, by 4500.

Not forgetting the 2wire 2700HGV!

Den · Oct 17, 2007, 19:49:41

I never will forget the 2wire 2700HGV, never had a router as good as it. 8)

Den · Oct 18, 2007, 18:27:36

There we go then! Profile back up to 6500kbps and just ran a speed check, it came in at 6327kbps.

Don't you just love idnet and 2wire 2700HGV.

Lance · Oct 18, 2007, 20:18:37

Great stuff!

Rik · Oct 19, 2007, 09:24:24

A result, Den.

Can I borrow some bandwidth, pretty please?

Den · Oct 19, 2007, 20:39:56

Friday again! Speed gone down again to about 4300kbps. Makes you wonder if BT are doing maintenance work on Fridays. Will just wait and see.

old Bill · Oct 20, 2007, 06:48:43

What software version are you running on the 2700HGV ? I used to get loads of DSL retrains then once the router had been updated with the latest software it stopped giving me retrains. So it may not be a line problem.

Den · Oct 20, 2007, 09:53:48

It's the most recent software. I had no retrains at all until last week end and my profile dropped at once. 8)

Rik · Oct 20, 2007, 10:04:06

I had that happen in August, sync speeds went down, attenuation went up. At the end of the month, attenuation went back down, sync went back up, profile recovered. I decided it had to be work at the exchange.

mrapoc · Oct 20, 2007, 12:05:39

Damn i need to reorder a 2700hgv lol

Im in the process of getting one again this time off a guy who assures they are new and not an import.

With SBC too so I can turn wireless up to access it at the top of my road

Rik · Oct 20, 2007, 12:09:08

It doesn't broadcast Radio 1, Sam.

mrapoc · Oct 20, 2007, 13:34:04

oh im sure i can mess with it a bit

does anyone know if theres any advantages for upgrading to the latest firmware instead of SBC at a lower firmware?

Den · Oct 24, 2007, 15:52:03

Hey, my sync rate is showing 8128kbps

But at the moment my profile has only (ONLY

) gone up to 6000kbps so is 500kbps down on what it normally shows. If my sync rate stays at this my computer will start to really fly or will it?

Rik · Oct 24, 2007, 15:52:56

How long have you maintained the higher sync rate, Den?

Den · Oct 24, 2007, 15:59:58

Don't know. Just came back to my study and there it was. Never had a sync rate like this before, This morning it was about 7500kbps and that was better than a couple of days ago (7136). Perhaps BT have been good at the exchange.

Ran BT test and it came up with the same sync so I will repeat again

8128kbps

Rik · Oct 24, 2007, 16:01:20

OK, sacrifice a lamb to the deities of BT and wait 3-5 days for your profile to lift.

Lance · Oct 24, 2007, 18:04:01

It seems more and more people these days are reporting higher speeds - it's not fair!!!

Rik · Oct 24, 2007, 18:04:49

It's not, is it.

Den · Oct 26, 2007, 07:36:39

Here we go then

Ran speed test this morning and came back with

6952kbps

Now if my sync can stay at this, these are speeds that I only dreamed about in the past. Once again top marks for Idnet and 2wire 2700hgv. Only thing now the guy next door wants to join us as he is paying Orange £17.99 for 1meg.

Happy am I.

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?

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.
