BT Infinit training period


[link to this post]
 
I had Infinity 2 installed last week (a week today). When i ordered they estimated i would get speeds of 36/6. On the day of the installation i was getting 26/3 and now im getting around 20/3. I've contacted BT and they told me it can take up to 10 days but i will definitely get the speeds estimated by the end of the training period. What confuses me though, is how the training period works. I'd imagine they would stick your line on the maximum it can handle and slowly drop the speed until it's stable. Or am i missing something?

There is no system whereby it tries speed A for 1 day, then speed B for 1 day, and then goes back to faster A at the end.

VDSL2 and ADSL and ADSL2+ modems will generally sync at faster speed they are allowed at the time, so the edging down suggests errors are been seen and for stability slower speeds are being forced on modem.

www.speedtester.bt.com or a hacked modem are needed to look at speeds rather than internet testers, which also test performance of the ISP

Remember that an estimate is not a contractual commitment to supply a specific speed.

So does this mean its actually going to get slower or stay where it is? Why is BT support telling me itll go up after the training period?

Cannot answer if it will get slower or faster. Need to see modem stats from before and after to comment more.

As for support - because they don't understand ADSL, let allone VDSL2, and are just saying what they've been trained to say.

Because the people who wrote the training manuals hadn't a clue and got it wrong. Back when ADSL Max was introduced.

The 10-day period, which doesn't, or at least shouldn't, exist anyway on Infinity, (so that shows how bad the BT Retail training is), always was and is misunderstood.

Sky LLU ADSL is a different matter, they run a DLM that does tend to lock people to a speed.

Sky FTTC is same DLM as all the other FTTC providers, ie not updated their leaflet

BT Wholesale is trying to explain MSR which is just recorded so they can see if the line is under performing at a later date

Is 15 meg slower than the estmation acceptable? Or should i complain my tits off? I dont know if the distance to the cabinet will make any difference to you guys, but im 300 meters away from it. is 21 meg 300 meters away from the cabinet normal?

EDIT: The bt speed tester shows my IP profile to be at 26/3.

Slower than to be expected. Is the throughput still slow if you use Ethernet between 1 am and 9 am?

Is the 300m a straight line distance or cable distance? If it is straight line, and the cable wanders around the streets and the actual cable length could be 600m ...

At 300m cable length, you should be getting 60Mbps and even with 600m, I would expect around 40Mbps or maybe a little less.

What is odd is the original estimate of 6Mbps upstream ... 2, 10 and 20 are the normal figures.

Dodgy line!

My brother is 580m - you can see where the cable trenches are, even after 10 years, and his potential sync is around 61Mbps.

I dont know which direction the cabe goes from the cabinet. But at it longest should be 300m. Shortest 200m. Here it is on google maps.

According to that map it's either 350 or 400 metres.

A little more information about my line. A few years ago I had ISDN installed and i chose to have the box installed upstairs so the BT guy ran a cable around the outside of the house, through the wall, round the skirtings and over the door frame for the second line.

When I had ISDN uninstalled in preperation for ADSL the BT guy disabled the socket downstairs so ever since the only socket with a signal has been the one upstairs. Could this be causing problems on my line?

I also read that when fiber is installed its common practice to install a new cable from the pole, but the guy that installed infinity didnt do this.

That's true! If pole fed.

It wouldn't be common practice even then though. It would be essential. To my mind the copper for the phone need not be affected, but might be.

Shows the overhead deployment, with the fibre tube and the telephone running along with it, i.e. changing existing drop is pretty much needed to get the new tube up, and the fibre through it.

The fibre lines can be spotted by the following two tubes leaving the manifold in

Is there something wrong with these results?

BT Test Results

IP Profile for your line is - 21.88 Mbps
Upstream Rate IP profile on your line is - 20 Mbps

If my line is so bad that my download is set to 21Mbps, then shouldnt my upload be set to something lower than 20Mbps? Confused!

Im expecting a call from the "engineering team" in the next 48 hours. Hopefully they can sort something out.

Since this thread is all about acheived speed on a 350M (or so) line length are you absolutely, 100% certain that you are connected to the PCP in question?

If you are how do you know?

If connected to a different PCP this would explain the speeds you are getting.

Have you got a Huwaea modem? If so you can unlock it easily and get access to the line stats which, in reality, are necessary to make any progress.

Re: BT Infinit training period


[re: wargasm] [link to this post]
 
I'm in a similar position to the OP - I'm just coming to the end of my 'stabilisation period' and am trying to work out if there's a problem with the install or not. I was also told by BT cust service that it would sort itself out at the end of the 10 days.

My pre-order estimate was for 50.4 down and 13.2 up. From the first moment the open reach modem (ECI) synced up I've had ~40 down and ~2.5 up according to various testers incuding bt wholesale. The bt wholesale tester has always reported my profile as 41.01 down and 20 up and looking at google maps I estimate I'm 700m to 850m from the PCP.

My connection is rock solid, the PPPoE connection hasn't reset once and it certainly doesn't *seem* like any DLM has been going on. Does any of this indicate a problem or should I just be happy with what I've got?

Edit - Not so worried about the download speed but had hoped the upload would've been closer to the estimate.

well unless you have access to the raw pppoe and sync stats you cant be sure its stable, and I assume you need to unlock the modem for those stats?

I have seen people say their FTTC is stable then they post a tbb graph which shows an obvious DLM resync (base latency changing after packet loss).
