ADSL checker - pessimistic max estimates?

Hi,

'superfast' 'fibre' just went live at my cabinet. The cab is 15m from my master socket yet the ADSL checker gives me a max (clean line) speed estimate of 64Mbit/s. Have people found that the checker is pessimistic or is it fairly reliable?

I guess there is a possibility that my copper follows the cul-de-sac around before getting to me and thus my line length could in reality be ~150m.

I'm weighing this up against a wireless provider who is about to go live in my area who will offer 100Mbit/s down and better upload too.

Best,
Arls
 
I just noticed that it gives all lines within the same postal code the same speed estimation therefore in spite of the tool's advice, the postal code checker is only as good as the exact phone line one anyway with regard to this info.
 
When using the ADSL checker you are best taking the impacted speeds as they tend to be nearer the mark. You also have to remember cross talk can cause the speed to drop as more are added to the cabinet.

also using addresses you are best using the full address link below which you will find on the adsl checker

When I checked for mine the estimate was for the full 80, and that is what I got, and my line is actually a LOT longer than I thought; I thought it went to the cab next to the Fibre box, but it seems it goes 50m the other way to a cab hidden behind a hedge first, so the line length is nearer 150m
 
Thanks for the replies folks. This just got weirder. The checker at AAISP estimates my line length at 1.2km. I guess ordering would be the ultimate test but I don't get how the line length can be 1.2km when the cab is 15m from the house and both were built at the same time (when the house was new there was nothing but this cab and my house plus the few around it, there wouldn't have been 1.2km of duct for a line to follow).

Anyone else found these estimates to be wildly out?

When you talk "cab", do you mean the phone cab or the fibre cab?/ You do realise they are different.

I have two cabs, each ~50m from my house, with the Fibre box 5m from the one to the left, so although the distance appears to be 50m, the cable goes across the road, then underground and right ~35m, then into the main duct under the middle of the road back to the fibre cab which is 85m the other way.

You may find your cable does something equally weird.
 
The fibre and copper cabs are side by side and there's little scope for anything to hide because it's all a reasonably new build estate and we've been her since the start.

I think I cracked it. The first Openreach engineer who came to put up the 28 day landowner notice for our fibre cab back in May commented that he'd had a hard job finding it because his map had shown it as being at the mini roundabout at the entrance to the estate. That roundabout is ~800m from the actual cabinet location. I'm thinking that the estimated line distances are based on postal code distances from that incorrect map and not anything cleverer.

I guess I'll know for sure when a neighbour orders it. If they get well in excess of those estimated speeds then perhaps that was the problem.

Luckily there are no long lines so nobody will be told 'no service' due to phantom long lines due to this apparent ~1km over estimation. With it being a new estate all the lines from this cab are 'downstream' from it as the estate was built in a linear fashion.

That sounds plausible; I discovered that cables/pipes/pumping stations are never where the map says myself, many years ago working for Severn Trent as a sub contractor.

For BT it can get even sillier; for years, trying to dial the Malvern area code from some overseas countries would get a message saying that the number didnt exist; I had this happen in Portugal and Russia during the noughties.

Hi! The 1.2km would be the line length to the exchange.
