Speed Question

MoHux · Dec 23, 2007, 21:59:59

Hi Wobbly!

Rik, he hasn't said, .............. Does he have filters on the other extensions (i.e. Phone Base Stns)??

Sky box??

$:-\$

Wobbly · Dec 23, 2007, 22:10:40

yes filters on the phone base units, no sky

noise margin seems to have decreased, thats bad isnt it?

The noise margin usually decreases at night anyway. I would really recommend ditching the extension wire, even just temporarily to test it out.

Hi Wobbly

Yes, lower noise margin is 'bad', but it happens after dark due to MW radio propagation plus things like street lights, so is normal - providing the router holds sync it isn't a major problem.

If you're picking up noise near your phone sockets, is there any mains wiring nearby?

Rik

Hard to tell, the socket is on a kitchen unit at floor level and the cable runs under the unit to the outside then up to a junction box where the upstairs extension comes off, so I doubt its near an electricity supply as thats all on the wall above the units.

Just run a test and its at proper speed, as it was yesterday morning

Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 5500 kbps
DSL connection rate: 448 kbps(UP-STREAM) 8128 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 5145 kbps

Next door have some Christmas lights on the side of their house, facing my junction box, they are off at the moment, I wonder?

Anyway, I have to leave it all now due to Christmassy stuff. I am really grateful for the help, I'm sure well get this sorted.

When Christmas is over I will try a better extension, if that doesnt work, move the router to the socket and run a cat cable back to the computer, and if that fails, move my computer nearer the point, but thats a last resort due to the way things are here. If its still duff, it will have to be BT.

At least you got me some brownie points by telling me to detach the ring cable, her indoors recons the phones dont "shush" as much now. Downside is she will be using them even more.

thanks again, have a good one

hmmmm

had a look outside - we had an extension built earlier this year and the power cable (big black thing) runs over the (white) telephone wire outside (cr*ppy picture - I have coloured in the power cable a bit)

Sebby · Dec 24, 2007, 11:06:00

This is quite a strange one. The results you've just posted from the BT speed tester show you're sync'd at full rate, and even though the profile hasn't caught up with the sync rate yet, your throughput is good. Yet, other times, your throughput is terrible for the same profile.

I'm just thinking if maybe it's the router that's to blame. Usually, I would say that, but... About a year ago, I had a Netgear and it used to sync very high, the SNRM was all over the place (often minus figures) and my throughput was poor, most probably because there was such a huge number of uncorrected errors. I'm just wondering if this is what is happening here. When I replaced my Netgear with a SpeedTouch 585v6, it immediately sync'd lower and the SNRM was solid. Throughput was perfect, too, because the SNRM was respectable.

Rik · Dec 24, 2007, 11:58:17

The power line crossing at right angles should be OK, Wobbly. Follow your plan and see if that helps. If not, Sebby's idea on the router would be a good one to check out, and obviously talk to IDNet.

Enjoy your Christmas.

Sebby · Dec 24, 2007, 12:02:58

I just think that we would expect sync to be lower at night, but from experience Netgears are poor on poor lines. You wouldn't believe it was the line when I connected the SpeedTouch to it. The Netgear was literally all over the place. If it syncs too high and the SNRM is poor, there's going to be a high number of uncorrected errors. I really think a SpeedTouch 585v6 or 2Wire 2700HG, with a shorter/better quality lead, could sort this out.

Sebby

thanks for the tip - got back from work - speeds have collapsed

, reloaded my old frog and they are still rubbish, but at least thats another thing out of the way!

Rik · Dec 24, 2007, 14:18:35

It has to be noise or a line fault then. Drop IDNet an email and point them at this thread, that will save you having to go through the basics again with them.

When you say "speeds have collapsed", has the router resync'd lower, or are you doing a speed test. So far, from what you've posted, your sync seems to be okay, but sometimes the throughput is suffering for no apparent reason.

By the way, the frog is not the thing to use to test if the Netgear is giving you problems. The frog will almost always be worse! I might be able to lend you a 2Wire router in a few weeks if you're interested.

Wobbly · Dec 24, 2007, 15:15:51

OK Rik, will do

Sebby - I did a speedtest and d/l is sub 500k. Thanks for the offer re the router, hopefully it will be sorted by then!

Sebby · Dec 24, 2007, 15:19:57

And what was the actual sync? Still 8128 kbps as it was when you posted earlier? I'm just trying to establish if this is a throughput issue or a sync issue. At the moment, it looks like it's a throughput issue, which I suspect is being caused by a large number of uncorrected errors.

Rik · Dec 24, 2007, 15:29:42

I agree, Sebby, I think there's noise at work - the issue now is to establish whether it's on Wobbly's side of the master or external. Never the easiest task.

Wobbly · Dec 24, 2007, 16:13:44

yes synch is 8128

Sebby · Dec 24, 2007, 16:20:43

Right. I'd really like you to replace that extension cable as, at the moment, I see that as the most likely culprit.

Rik · Dec 24, 2007, 16:22:07

I agree. Until that's eliminated we won't really be able to move forward.

Wobbly · Dec 24, 2007, 16:51:55

its on its way!

Sebby · Dec 24, 2007, 16:52:30

Glad to hear it!

MoHux · Dec 24, 2007, 19:48:18

I picked up the bit about SWSBO saying the 'shush' had dropped when the ring-wire was removed. Have you done a quiet-line test at all Wobbles? When the speed drops would be the time perhaps.
Rik will tell you how, I can't remember the number. (age thing!

)

Rik · Dec 25, 2007, 00:25:33

17070, option 2, Mo. I only remember it because I have it programmed into the phone.

Wobbly · Dec 25, 2007, 07:38:45

Morning, been up since 5.30, grandson is staying

After a slow day, speeds recovered in the evening and I got this result last night - the IP profile for my line has risen by 1,000kbps???

IP profile for your line is - 6500 kbps
DSL connection rate: 448 kbps(UP-STREAM) 8128 kbps(DOWN-STREAM)

then tthis morning its flying

Just keeping a record

Rik · Dec 25, 2007, 10:22:42

It looks like the line is recovering, all we need to do now is work out what from. Unfortunately, that's the tricky bit with intermittent noise. What's the weather been like in your area, eg cold, wet or...

Wobbly · Dec 25, 2007, 10:28:41

Mild and wet Rik, I'm in Dorset
