FTTC Sub 15Mb

From the BT broadband checker I get the following for my line:

Our test also indicates that your line currently supports a fibre technology with an estimated WBC FTTC Broadband where consumers have received downstream line speed of 11.1Mbps and upstream line speed of 4.4Mbps.

Is this estimate calculated from the exchange to the cabinet or from the exchange to my master socket?

The reason I ask is because I would like to find a way to increase that estimate over the minimum 15Mbps threshold.

I have 3 junction boxes from the drop cable to the master socket and I was wondering if this section was included in BT's speed estimate whether if I was to replace this junction boxes with a new drop cable to a new master socket located in a more accessible place within the property whether this would make BT re-test my line speed?

I'm currently on BT Broadband option 1, with these line stats.

Its an estimate of what to expect at the premises and maybe off a little or a lot, though it will prevent you ordering Infinity .

Although it will prevent you ordering "Infinity" BT have a separate product for sub-15Mb/s estimates ("BT Broadband with fibre" I think - search the forums) and several other ISPs will take orders for FTTC where the estimated speed is less than 15Mb/s

If you get connected you might find the speed to be quite a bit better - my estimate was 26.8Mb/s but I connect at the full 40 (or just barely a smidge off, still enough for the fastest IP profile speed of 38717Kb/s)

It is an estimate from Cabinet to Premises.

The stats you show will have NO bearing on the estimate.

What is the point in increasing the estimate if the final result will be the same? A few metres of cable in the house will have negligible effect. Go for the sub-15Mb product and if it rises above then you are in luck.

I have the 'Broadband Option 3 with Fibre' as Infinity here was estimated as 14.6Mbps, so couldn't order it.

However, my Fibre connection D/L is well above the estimated speed and goes at 25Mbps and is reliable at all times. About 600 Metres from the Cabinet.

Upside is with Infinity you can have a 10Mbps U/L whereas With Fibre it's capped at 1.5.

Not a problem for me as I rarely upload much.

Just wish BT would not charge 'With Fibre' Customers the same as for Infinity.

Are you sure it's capped at 1.5Mbps connection speed, or is it 2Mbps connection and 1.5Mbps is what you get as throughput? What does the BT speed tester show?

There seems to be nothing you can do to change the estimate. The estimate does not seem to work on anything more than the length of cable from the cabinet to the pole. Even if the information held in the BT database is wrong they will not let you order Infinity. Way to go BT, make it harder for potential customers to order your product.

I wanted to order infinity but couldn't due to their incorrect estimate of 12Mb turns out I have over 20Mb with my new ISP IDNet. Even now informing BT that the line runs at over 20Mb they still would not do anything about it. I have a second line that I would like to put on infinity but they won't budge, the BT Broadband with Fibre is not a suitable alternative for me. So BT your 'computer says no' attitude is loosing you customers!

I wonder if when BT start using the new 80Mb profile the limit for Infinity will stay at 15Mb or be updated to 30Mb ?

That is a 2Mb max upload speed - but I have yet to find anyone with a 2Mb upload who achieves better than 1.7Mb ...

Pretty much the same as the 10mb product topping out at about 8Mb, i can never get over around 8-8.1Mb in speedtests

Which is due to the sync speed and IP profile both being 10000kbps, unlike the downstream where most users get 40000kbps sync with the 38717kbps IP profile.
