IP Profile - is it stuck/restricting my download s...

Question

After my recent extremely slow DL speed issues and intervention by the moderators, my BT Total Broadband now appears much better.
However, my IP line profile appears now to be stuck at 2000, even though I am syncing at over 3000.
Note: My previous ISP, Tiscali, provided me with a consistent 2500+ Kbps actual DL speed for 2 years.
My internal wiring/noise is OK according to the BT Openreach engineer and I have had the line checked and a new master socket fitted.
Please see below my latest BT Speedtest and ADSL Hub results from last night.
Below that is a another set of results recorded a week earlier on 14th November, which actually show my expected DL speed was being provided! How come this happened on only one occasion and since then has not repeated itself?  The hub is left on continuously and not switched off.
Is my Ip profile stuck and how can I get the jam cleared?
Any advice would be welcome...

Answer 1

After 15 days of uninterrupted syncing at 3000+ Kbps, my download speed is still  around 1500 Kbps, because my IP line profile remains stuck at 2000.  I know that this bottleneck on my line is at the BT end, as as I stated previously, my previous ISP (2 years +) and BT (3 months!) consistently delivered over 2500 Kbps DL speeds with absolutely no problems.
I am losing all faith in BT, as I am not getting the service promised (fastest possible line speed) when I signed up with them.  I have been very patient, but am regretting moving to BT from a very good previous ISP and am considering making serious complaints about the poor product delivered.

We were unable to identify any performance problem with your service at this time.
It is possible that any problem you are currently, or had previously experienced may have been caused by traffic congestion on the Internet or by the server you were accessing responding slowly.
