Well a few things. I had an engineer come round yesterday to have a look at the line. Firstly, I asked him about which cab I was connected to and it seems I was wrong about the one I thought my line was connected to. It seems the cab is around 300-620m away depending on whereabouts it is situated on that road which I'm not sure. Secondly, he used a tester which he plugged into the master socket and told me the machine was telling him that the max I'll see is 22Mb. I was disappointed to hear that but he said he'll have a look into it and see what he can do and see if it can be resolved.

I want to know, at that distance (300-620m) *should* I be seeing close to 40Mbit provided the copper and the line is in good condition etc. Or is that distance too far? Basically, at what distance from the cab would you have to be before you started to notice a drop in speed from 40Mbit? And even if that distance isn't 40Mbit capable surely it should still be better than the 18-19Mbit I'm currently getting? Could it be an external issue i.e, the copper from the cab to the premises not in good condition? Call me stubborn but I don't accept that 20Mb is the best I'll get. There must be something that's hindering it, the fact that the engineer said he'll have a look into it gives me some sort of hope. And you're right, the speed I'm currently getting may not be that far from the quoted speed but it's still below it, and I've read many posts here and elsewhere where people have been quoted much less and still got the full 40mbit.

300 to 600 is quite a range when it comes to FTTC.

For example we're almost certainly about 600m from our cabinet unless the cable takes a weird route (even by BT standards) and get in the 25mbit range.

It depends on the copper or, if unlucky, aluminium. When was your house/estate/area built? Is the cabling underground? Can you come up with a more accurate distance to the cabinet?

Not being harsh but it just seems at the moment you only have very general information and assumptions but are using it to make concrete estimations of "what I should be getting" even though you're getting roughly what the checker thinks you should.

Well I don't know exactly where the cab is located on the street I was given. But I worked it out from google street view that, at the closest it's atleast 484m and at the far end of the street about 643m. So it must fall within that range. Now some of the posts here have said at 400+m they've got a sync of 40mb. In fact someone around 800m away was syncd at the full 40. Now fair enough if I can't get the full 40mbit but surely at the distance I've given I should be atleast getting 30mb if not slightly higher. You would need to be atleast 1000m away from what I've read from the cab for the speeds to tail down that dramatically (i.e below 20mb)

As for when the house etc was built, that I don't know but I'll try and find out. The cabling is all underground (how else would it be?) and then to the pole.

And as for the checker. I was quoted 26mb and I'm getting 18 currently. So with due respect, no. I'm not getting roughly what the checker thinks I should. Nowhere near it. The majority of people here and elsewhere have got more than their quoted speed as it's conservative and here I'm getting much lower. Something isn't right.

As I've said before, there's no way I'm accepting this is the best I'll get. I'm not exactly a million miles away from the cab. At that distance I think it's reasonable to assume I should be getting within the 30-40mb range or atleast 30 minimum not the 18 I currently get!

Well the cabinet is pretty close by so it's not far off to assume that I should be getting better than just 20Mbit, and the engineer said I should be atleast getting 30Mbit. That and the checker being conservative.

But anyway, I finally restarted both HH and Modem again today after it being on for over 4 days and it just dropped again this time down to an IP profile of 18890. It's been a week now since Infinity was installed and I haven't seen a profile above 20. Could this be a fault or something or perhaps a stuck profile? Would calling BT be the next step?

I'd appreciate any help.

As with the exchanges it does not mean you are connected to the nearest cabinet nor will the cable necessarily take the most direct route

Well in your first post you were getting 21mbit and as mentioned by others it's highly variable. I've mentioned on other posts that our line sometimes drops to 15mbit or even 7mbit for periods and then goes back to 21-25mbit. We were quoted 27mbit on the checker but remember it's just a guess. It isn't set in stone that you will get that. You even say yourself some get quoted a figure and then it's faster. Some get lucky, some unlucky and I'm sure for another percentage it's actually just about on the money.

As an aside, what's your upload speed like? Get the full 10mbit or closer to 6-7?

It uses VDSL2

maybe this will help ?

Be wary when considering the distance to the cabinet.

Geographically, the distance from my house to "our" cabinet is 25 yards, literally across the road.

Electrically/telephonically, it is at least 150 yards, as the line goes from my house, away from the cabinet to the far wall of another house about 70 yards away on our side of the road, to a small jointing box at pavement/footpath level, about 15 inches high, 2 inches by 2 inches, before PROBABLY crossing the road and heading for the cabinet.

Compounding it, the main cable to the exchange comes directly back across the road to an underground jointing box, originally one panel in size - but enlarged to three panels about 1986 (panel dates); and no doubt there are several more in the 1200 yard road distance to the exchange.

All the local Domestic-distribution cabling is underground, as the whole estate was pre-wired during building in 1967.

I only became aware of this routeing in the 1990s, when we had problems with the line which turned out to be in the exchange.

During the investigation, a BT engineer came to check the local wiring, including re-making the wrapped-wire connections in this small jointing box.

Although that did not eliminate the problem, it did improve the dial-up modem connections of that era.

The basic problem was only cured by transferring us on to the more modern exchange unit in the exchange building, involving also a change of number.

A message was left on our answering machine that the transfer had taken place - BUT did not say what the NEW number was.

It took twenty minutes negotiating with BT to be told it - by suggesting to the operator that she ring the new number and give it to whom-so-ever answered!

Before the days of CLI etc.

Yeah, I did get 21Mb initially but that didn't last long and I haven't seen those sort of speeds for the majority of the time I've had Infinity installed (2.5 weeks now). The thing with my connection though is that I'm not getting the kind of extreme variable in speed that you've mentioned. It's always either 18, 19 or 20 and the connection itself seems solid without disconnections.

Atleast your speed of 25Mb is much closer to your quoted speed. Unfortunately mine is no where near it. However, I'm still going to pursue the matter as the case is still open for a few more days. Switching over of ports didn't really seem to do much apart from lower the ping. I want to get atleast some sort of confirmation from the engineers as to why this is the speeds I'm getting.

As for the upload speeds. I usually get around 8.0 - 8.2. Sometimes high 7's.

That graph is rubbish.

Looks like you have a rubbish line and prob ALU in the loop.

That graph is far from rubbish and illustrates the speeds available at varying distances when connecting using VDSl, ADSL2+ and ADSL

According to that graph, the speeds I'm getting now represents a distance of 5000 feet (1524m) from the cab. My cab at the most is 640m away which should give a baseline of around 50Mb. Hmm.
