Can you try powering the router off and back on and pasting those same statistics as soon as the router comes back on line? This would tell us what your router is capable of at first connection - it would be especially useful to do this twice - once after dark and again at about 10am or after (the differences between dark and daylight hours can be quite significant).

It is possible that given the high noise margin you have it may be that you could actually get double the speed from Sky and that it is the BT profile system that is slowing you down.

BT speedtester (I haven't used that speedtester before).

The main point of this speedtester over all others, when you are on IPStream/ ADSL Max as you are, is that it gives your IP Profile, which is BT's DLM ceiling on your actual download speed, thus:

IP Profile for your line is - 2000 Kbps

The useful section that we wanted is the "1. Best Effort Test".

Your line should be capable of about 4 Meg Sync but you are only getting about half that. Your D/S NM is high which could indicate your line is noisy. Time to look at your wiring.

Have you removed the ring wire? Plugged into hidden test socket? Filters? ...

That's just great! Exactly what we needed. Continue that way when you post stats.

No, the IP Profile is dependant on the Sync Speed and it is that that is too slow by half. More likely due to noise on line.

Yes. But, it could be that the router during the day can sync at 4Mb+. But, if it resets then at night to 2Mb then the profile will lower and stay that way for days. By avoiding the profile on LLU the user could reset the router of a morning and get 4Mb during the day whilst getting a lower speed at night.

Therefore, it is the BT profile system that is slowing the OP down (probably).

No.

The sync-time noise margin is what is slowing him down, as the IP Profile is right for the sync. The sync is too low.

You would be correct if the profile were too low, for the reasons you give.

Not quite sure what is going on here. The sync had occurred 16 hours before the post - so during nighttime hours (I believe). Therefore the SNR at a resync could be significantly lower than the current 16dBs. It may even be a 6dB SNR with a wild variation between day and night.

This is the main reason I asked for a daytime resync with stats straight after - it would tell us the maximum speed the line is capable of and the target SNR.

Therefore I still stand by what I said - it could be the profile that is causing the slow speeds due to low nighttime syncs which could be got around with sky as you could then reset the router each morning to get max speeds for the daylight hours.

About 18 months ago I was having terrible trouble getting any broadband service - speedtest (not the BT version) - was giving my download speed as 0.5mb or lower and I was losing the service completely frequently.

I got an Openreach engineer to investigate and do some tests but he worked locally and knew immediately that the main problem was the line distance to the exchange and his statistics confirmed this. He rerouted my line but I think it must still be about 3 km. He also replaced my main socket and checked that the wiring appeared to be fine. I think I then got over 3mb speed for a while before it returned to about 2mb, perhaps because more houses have been built in the area and there is more contention.

My next door neighbour has SKY and he says he has very poor speed (unfortunately I don't know the actual speed) although the service never goes down. BT told him his line would not support BT Vision. I suspect he has the length of line I used to have and there is now no capacity to offer him a shorter line to the exchange.

I will try about 5pm to get the statistics again from my BTHub (after disconnecting and reconnecting) as soon after I will not be the only one using our Hub.

What I am hoping from the help I am being given on this site is to see if I (or BT) can do anything to improve the speed of my internet service or should I go over to SKY in the hope that they will offer a better service.
