Upped to ADSL2+ and still on the dark age

Generally, I'd say yes, Gary, but Sky boxes are well known for getting through the filters.

Thats bad what on earth can make them cause that much issue, the modems must be awful, well I suppose they are sky boxes

Rik · Jul 09, 2009, 17:38:54

I've known one Sky box take out an entire street, Gary, it was putting so much noise on the line.

That is bad, thankfully our HD box seems ok, I cant bend down on my own to unplug and plug it into the wall. but its though an adsl nation filter so

Unless you have multi-room, Gary, or use PPV a lot, I recommend leaving them disconnected.

I get films out Rik when Justina is away so its not practicable for me

Rik · Jul 09, 2009, 18:09:57

Fair enough. I suppose you could use an extension at a more comfortable height for the Sky lead, otherwise double-filter it.

troesma · Jul 09, 2009, 20:34:07

OK chaps, came back home, and did the roll call...

1. Sky box out = checked..!
2. Modem powered-off before disconnecting phone line = done..!
3. Modem hooked into BTs main box = checked..!
4. Ring wire (pin 3) disconnected througout all phone extensions in the house = checked..!
5. Left modem to cool-off for at least 30 mins = done..!
6. Used 2 ADSL filter boxes to rehook mains phone (wireless station, just in case) = done..!
7. Powered-up = done..!

And what I get is

Its easier as it is for now, Rik. Anyway I have a good sync so I'll leave it, but that's a good idea for a future time.

Hi, sorry for the stock reply, and I'm not saying this to wind you up, but we haven't found speedtest.net to be the most accurate, so we always recommend people to use the BT Speedtester, as this also shows your profile. If you'd like to do one and post it, someone will advise.

As requested... at 21:10 PM today

Test1 comprises of Best Effort Test: -provides background information.
Your DSL connection rate: 3748 kbps(DOWN-STREAM), 888 kbps(UP-STREAM)
IP profile for your line is - 1000 kbps

Actual IP throughput achieved during the test was - 907 kbps

If you wish to discuss these results please contact your ISP.

Whereas AM today

Test1 comprises of Best Effort Test: -provides background information.
Your DSL connection rate: 3483 kbps(DOWN-STREAM), 888 kbps(UP-STREAM)
IP profile for your line is - 2500 kbps
Actual IP throughput achieved during the test was - 2319 kbps

If you wish to discuss these results please contact your ISP.

Modem statistics follwoing the new set-up are

DSL Driver Version: AnnexA version - A2pB022g.d20e
DSL VPI/VCI: 0/38
DSL Status: ShowtimeRetrain Reason: 8000
DSL Mode: ADSL2
DSL Channel: FAST
DSL Upstream Rate: 888 Kbps
DSL Downstream Rate: 3748 Kbps

DSL Noise Margin: 13.9 dB / 6.3 dB (down/up)
DSL Attenuation: 41.5 dB / 23.5 dB
DSL Transmit Power: 0.0 dBm / 12.8 dBm

Earlier PM (with SAME setup) NL went to the 25db region. Should I assume BT is tweaking things at their end..?

troesma · Jul 09, 2009, 21:24:08

Update, at 21:21 modem stats NOW show

DSL Noise Margin: 10.2 dB / 5.1 dB (down/up)
DSL Attenuation: 44.0 dB / 23.3 dB
DSL Transmit Power: 0.0 dBm / 13.0 dBm

so it seems something is going on at the exchange...

Why ATTN is poking upwards..?

rireed3 · Jul 09, 2009, 21:37:11

This is improved a bit, believe it or not.

The profile will come up to 3M if you keep this sync for between a few hours to 3 days, meaning leave well alone for a bit.

Don't know why the ATTN changed, but leave well alone for a bit.

I think you should get a 5500 Kb sync. at 44 db. You'll get some improvement after two weeks on this sync when DLM lets you sync to a lower noise margin, but it looks like there is still extra noise holding you back. You may not be able to eliminate this, but have a look here:

DSLZone 'improve your speed'

In any case leave well alone for a bit.

If you must fiddle, try not to re-sync more than once in 24 hours, and always turn off the router whilst working.

Ted · Jul 09, 2009, 21:47:49

i believe your attenuation rises as the sync increases on ADSL2+. Things are looking better except that your profile has taken a hit for some reason, obviously this will affect your throughput. As Richard said, leave everything alone now and allow it to settle, the profile should rise again soonish.

Ted · Jul 09, 2009, 21:59:50

Forgot to ask what router you have? Also can you find the DSLAM Vendor Information in it? It would appear that some router \ DSLAM combinations don't work too well.

troesma · Jul 09, 2009, 22:00:58

Thanks folks, I'll leave it to settle and check things AM tomorrow to see if the profiling has changed upwards. Maybe NM would go down to 6db at the point where I know I'll be hitting the wall in terms of speed. As said, checked ALL CONNECTIONS (on BT Master and extensions) removing the ring wire, ensuring everything is tidy, even pur 2 ADSL filters in series to hook-up my phone wireless extension. Line does not show any signal of noise. Let's pray...

I'll check on the DSLAM bit in a sec...

Apologies, cannot find it...

Ted · Jul 09, 2009, 22:38:25

No worries, it was just a thought, its unlikely but you never know. Nice router by the way 8)

Sebby · Jul 10, 2009, 00:13:34

Unfortunately, BT's system means that if your line is unstable, your profile is going to suffer, which in turn causes problems with throughput.

troesma · Jul 10, 2009, 17:14:20

OK, this is now getting me ANNOYED TO THE EXTREME

Some decent number of hours following my checks on the wiring and doing all the right stuff where needed...

Test1 comprises of Best Effort Test: -provides background information.
Your DSL connection rate: 3759 kbps(DOWN-STREAM), 1010 kbps(UP-STREAM)
IP profile for your line is - 1000 kbps
Actual IP throughput achieved during the test was - 919 kbps

If you wish to discuss these results please contact your ISP.

And checked the modem stats just now, NM gone UP again to 15.1db.

In addition, I now have NO PHONE LINE (there is no tone... it was working fine yesterday).

WHAT THE F**K IS BT DOING..?

I'm now worse that where I was before the change: lower DL speed (thanks to lower profiling which has not changed in 18 hours) and no telephone line. HEEELP

Rik · Jul 10, 2009, 17:16:08

Report the voice line fault to BT, don't mention ADSL. Are you sure you haven't dislodged a wire anywhere?

Your profile is suggesting instability and frequents re-syncs. What router do you have?

troesma · Jul 10, 2009, 17:16:58

As said above, a Linksys WAG160N which has worked flawlessly.

Of course, forgot to mention I have a cr*p ADSL service working...

Rik · Jul 10, 2009, 17:23:51

Sorry, I should have remembered that. You need first of all to get your voice side straight, so make sure that you haven't knocked a wire off anywhere and then report the voice fault to BT. You've had 10 re-syncs today, six within seconds of each other. That's going to cause DLM to kick in and push up the target NM and down the profile, which is exactly what you're seeing. If the re-syncs weren't triggered by you, you need to establish what is causing them. Routerstats, if you can get it to work with the Linksys, might help establish a pattern.

troesma · Jul 10, 2009, 17:25:05

The line has not been in use today until now... I'll check what's going on in a sec...

troesma · Jul 10, 2009, 17:48:48

Found the culprit... phone line knocked off by missus...

Phone line back to life.

Now to sort that ADSL issue.
