Roadworks are planned in january to swap my existing cabinet with a All-In-One Cabinet, but I live 1.5 Miles away from it, and currently only get 2Mbps speeds, with a total line length of 3 miles. Any idea what sort of speed bump I will get?

It really is hard to say, It could be good quality line, Im just over a mile from my cabinet with about 1.5mile length and get 21mbps, if its any gauge on ADSL used to get around 6.5mbps. Are you getting 2mbps due to the length or due to your package being capped at that?

An All-in-One will not significantly change the ADSL speeds you are getting. It would be interesting to see what your line stats are to see if there is any room for improvement though.
For FTTC (VDSL) - at around 5km it really is at the extreme boundary where speeds of 1Mbps might just be available, if BT want to even risk trying to supply it, so do not bank on it.

It is 5km all the way to exchange not to cab, cab is approx 2.5km away.

Need the coffee before I start!
Even at 1.5 miles - 2.5km the prospects are not good and certainly variable. Two people know, served by the same cabinet and same cable for 80% of the route. One at 2.4km gets about 4Mbps, the other, at 2.45 cannot even anything! Even the 4Mbps sped varies and is often very error prone.

Yeap could be zero or could be 4 Mbps, only way to know for sure is to try.

Is that a 2wire 2700?
There should be a little more speed available on that given the 9dB SNR, unless the line sees frequent noise burst or the day-night variation is several dB.
Try a power off, reboot and resync tomorrow morning at around 7:00 or 8:00 AM. Power off, leave for a minute, disconnect line. Wait 5 minutes, reboot modem, wait 2 minutes then reconnect line.

Yeah, a 2 wire 2700 BTHub 4/5 only manages a sync of 1mb! Line used to have a SNR of 6dB and ran at 3200kbps, but kept dropping at night.
|
|
|
Thought I recognised the stats format ...
From quite a bit of experimenting and testing a few years back I found that re-sync about an hour after sunrise gave the best results that would also allow it to hold up permanently. Mine would actually go right down to 0dB SNR at times and sometimes lower.

unless you move onto FTTC speeds should stay the same or get worse (due to messing with the wires),(which is on ADSL 1 mode on your modem, with 448 upload your likely on a 8mb/448kbs profile)
if you do move onto FTTC(VDSL) it might be better than what you're getting right now (1.5miles is pushing it on VDSL but still should be faster than ADSL)

Will BT let me order it though on a 1.5 mile long line?
Worried about this statement:
"Openreach provide the following guidelines from national results: Premises up to 200 metres from cabinets get 50+ Mbps; those up to 500 metres achieve between 25 and 40 Mbps; up to 900 metres they achieve from 15 � 25 Mbps; the minimum 2 Mbps service reaches out to 1.2 miles."

Where is that information from?
I am at 400-450 metres and I am synced at 76Mbps and have at been at >78Mbps.
As for ordering ... it will depend on what the checker says - you will not be offered Infinity, however there is a "faster Broadband" option which still provides FTTC. All I will say, it don't hold out too much hope and then be disappointed.

seen another topic where 1.5km ish line did 15mb/s (it is bit pot luck on the phone cable quality past 1km)
Openreach do like to under estimate speeds so to cover themselves (shouldn't be any worse then ADSL your on right now as the line will be shorter on VDSL)

Actual results depends on the gauge - the thickness - of the copper wires. BT have options, varying from 0.32mm through the "standard" 0.5mm to 0.9mm.
The thinnest copper may be used for a segment out of the exchange building, where underground space is limited. Thicker copper can be jointed in, as the cables radiate away from the exchange - first at 0.4mm, later at 0.5mm.
The very longest rural lines probably have some component using 0.9mm copper - and this can sustain speeds at 3x the distance of 0.5mm cable.
So will BT let you order it?
Their estimates will take into account what attenuation the copper line is expected to be to your DP, which depends, in turn, on the gauge. If the estimates say you can get a service, then you can order it. They don't base the decision on the distance.

This is my result, is 2.5Mb a good speed for a 3.5 mile, 5.63km long line? Any indication of line quality?

Of course you're absolutely right about gauges of wire. But for the last few years and certainly now OR only use 0.5 copper unfortunately. Regardless of distance from the exchange. I'm fairly confident engineers can't even get the thicker stuff from stores now.

I live a slightly shorter distance to our box, after several engineers visits where the line was checked from box to our house to ensure all was working at best, we now getting an average speed of around 3.8mb, but with so many errors it is debatable if it's any better when jumping page to page than when on ADSL at 1.2mb, although large files do download faster
