Is this any good?

Ok already on adsl2+ and a good speed for a 50db attenuation, ie not likely to go faster

Thus spikes of speed were most likely not real

For a 50dB attenuation line - that sync is good.

That's ADSL2+.

Please can you try something for me? Run the BT Performance Test, and on the results page go down to the bottom and click the Further Diagnostics button.

Then see if it accepts your phone number and gives a page showing IP Profiles and a bar-graph. If it does, that tells us a lot. Also, in that case, the downstream IP Profile would be interesting.

Thanks to all who've been helping.
You really are stars.

I'm suspecting the poster was on non-LLU 8Mbps in the past, has been kept there after TT LLU'ed the exchange, the 20CN kit is removed and the line goes onto WBC.

On a clean line that would explain the high sync with a 3dB noise margin.

I'll try that for you tomorrow, if you don't mind, Sir. I'm a bit busy at the moment.

It proba almost certainly won't work. It's just a possible scenario that could be a large part of the explanation. I'm more expecting it not to recognise the phone number in the Further diagnostics screen.

So probably not worth doing then?
The general concensus seems to be that my line is operating as it
should do and that the unusually high download speeds are just
false spikes. They only occur when using Wi Fi.
When using a wired connection, the download speed is stable at
around 6.5Mbps.
Thanks again for your input.
