new connection stats up speed low

Hi all, my son has just connected (yesterday Sat.) with PN using PN router, but the stats look a bit iffy for the up speed. He has a new ADSL Nation faceplate at the master socket, with an existing upstairs extn. socket where the router will go next to PC, this extn. he wired to the unfiltered B & A terminals on ANation faceplate as no phones will be using this extn. However there must be still other wiring issues as the extension is dead, so for now the router is in master socket, with the extn socket still connected to B,A.

Thruput on TBB test is low 6306 d, 371 up. I said he should pull out the wires from B,A, until he has time to sort it all out,and see if up speed goes up, but he is a bit wary of BT's MadMax profile system changes, esp in first 10 days. Should he pull the wires out B,A,? I said I would enquire for him as he is out till this evening. I also think the down power is low, I had this once with dodgy wiring.

Thanks

A few clear photographs of every socket and the wiring connections inside each will be worth a thousand words.

If, as you say, your son's attempt at wiring a broadband extension fails to work then revert the changes now. There is no point in waiting.

Well from the stats posted there doesn't seem to be any reason why you would not expect to see the normal 84%+ throughput , if you could post some more stats after say at least 24 hrs sync , to see what the error rate is like, the only other thing that would affect throughput from your side is the MTU being set correctly in the router, or something wrong with the router it's self, but it's more than likely a bt(pn issue at the exchange

At a guess your problem is either a stuck IP profile of 7150kbps (normal max on ADSL1) or the Plusnet mirror of it - Current Line Speed https://portal.plus.net/my.html?action=data_transfer...

Thanks all, I'll talk to him later.

The daisy chain extensions were already there, with cables run in the walls as with most new builds. On my advice he had all the faceplates off and just connected 2 and 5, as the installers had all six wired up, doh. He was going to use the upstairs ext. for the router.

I'll get him to pull the extn off the B and A terminals and get some stats from him, BTW he lives 190mls away,otherwise I'd go myself,lol.

thanks

That doesn't bode well. Wiring by a electrician as part of a new build is (unfortunately) often sub-optimal for a broadband service. I would say that an annotated set of clear photographs of the wiring at each socket is definitely the order of the day.

Will endeavor to get this. Nearly at 24hrs so will wait for stats. In meantime before he connected to master socket he said theres no continuity on any of the pairs (he is an AV technician BTW so does a lot of wiring) but he forgot to dis the B & A connection before syncing for the 1st time. Has also now found another extn. socket behind a fixed wardrobe, guess thats where prob is.

On a personnel note just noticed I am on G.992.1 Annex A, usually G.992.5 Annex A, is there any difference.

thanks again

Yes,

G.992.1 aka G.DMT (ADSL) up to 8Meg

G.992.5 aka ADSL2+ up to 24Meg

> > > ADSL

Yes,

G.992.1 aka G.DMT (ADSL) up to 8Meg

G.992.5 aka ADSL2+ up to 24Meg



Cheers, Will get stats tomorrow, son just got home.

My stats guess anything can happen on o2. lol

Hi all, my son has just connected (yesterday Sat.) with PN using PN router, but the stats look a bit iffy for the up speed.

The upstream sync rate is 448kbps according to your stats. We cap the upstream at this speed at the Wholesale level. It can be uncapped by following the instructions under the 'Key' section here.

Thruput on TBB test is low 6306 d, 371 up.

That does seem low considerign the downstream sync speed. What does a BT Speedtest tell him?

Rgds,

Rgds,

I had a quick look, I assume he can do this himself?

Thanks

That looks a lot like an ADSLmax connection's throughout speeds.

Yes, he should be able to do it himself (he'll need the account login details to raise the support ticket to uncap the upload though).

Increase of 10k

New speed test here http://www.thinkbroadband.com/speedtest/results/id/1...

Guess its not a stuck profile at that thruput. He's going to raise a ticket to get the up speed changed.

Cheers

No worries, feel free to post the ticket ID here if you can get hold of it and I'll pick it up tomorrow...

Due to BT's MTR being the lowest sync in 1st 10 days, he will now raise a ticket next week if current sync does not change.
Thanks

MSR >> FTR. (FTR is 80% of MTR).

Neither affects the speed the line sync's at, ever. What the FTR does is provide a baseline above which a low sync fault report is unlikely to be considered.

Which means if the lowest sync in the 10 days was 6Mbps the FTR is 4800Mbps. If the normal sync is around 6200kbps but drops down to a norm of 4900kbps, tough! If there was a low sync during that 10-day period, perhaps 5Mbps, the FTR would be 4000Mbps, so given the normal 6200kbps again, a persistent drop as low as 4100Mbps is regarded as acceptable.

The only easy way to get the MSR and FTR reset these days is to ask for an SNR reset. That redoes the 10-day training with the SNRM set to default 6dB at the start.

Thanks, it was after looking at your site, I based on if his sync stayed at 21,176 for ten days that would be the MTR giving FTR of 16,940.

Just had a thought unless I've missed something, are BT's MTR & FTR based on the old max of 8128 regardless of sync over that?

A and B - odd if using standard BT sockets then should only be connecting to 2 and 5.

Some ADSL faceplates replicate the A and B so as to provide an unfiltered extension, so an ADSL modem can be situated away from the faceplate. Not recommened to run a phone extension from those connectors.

Photos are needed really, as peoples descriptions vary so widely

Its an ADSL Nation plate, but the unfiltered extn. when he sorts it will only be for DSL, not for phone.

It's good to know you got the theory from my website , but there is no such thing as MTR - it's MSR. Otherwise, yes, you're right.

I got a little confused because of your own stats appearing in the thread, with a much lower sync.

I don't think the old 8128 is at all relevant. I haven't checked, but believe it applies all the way up ADSL2+.

Re raising a ticket, I assume that is purely about the upstream 443?

Yes I meant MSR and it was only the upstream. l'll et him know the MSR etc is only up to 8128

Who said that? I certainly didn't.

No it was o2 whom I spoke to since your post, Ive' got my own sync probs to deal with as well, although on their LLU it cropped up about about their FTR's, so I asked them the question.

Sorry to have implied it was you

You are getting yourself screwed up as well, by asking the wrong question of O2.

On O2 LLU there is no MSR because that is a BT Wholesale thing. Neither on O2 LLU is 8128 a significant figure - in the days they limited the bottom package to 8Mbps it was a true 8Mbps = 8192kbps.

So asking them about MSR and 8128 is going to make them think you are referring to the non-LLU O2 Access, which is a BT Wholesale circuit. Specifically it is ADSL Max, not ADSL2+.

As such, the answer they gave was correct when the ISP is O2. The MSR does stop at 8Mbps and does not change above that, because 8128 is the highest non-LLU speed. If you are on a higher speed than 8Mbps on O2 then you are on LLU and the MSR doesn't even exist, so cannot be higher than 8128.

On the ADSL2+ connection we are discussing I am 99% certain it applies all the way up.
