In answer to your questions in post #4:
1) Yes.
2) Although I'm sure we mean the same thing, I'd say close to 7 Mbps. Strictly speaking you are using the wrong units.
3) It is most probably not TalkTalk 'slowing you down'.

You're connected at 6.6Mbps and should be seeing maximum download rate around 813.96 kB/s.
Could you please show how you figure that?

Your sync is rubbish for the attenuation, depending on your package you should be seeing over double what you have.
Not really - welcome to ADSL Max using ADSL1 modulation. I agree, however, that you could reasonably expect twice the sync rate for attenuations below about 30 dB on an ADSL2+ service.
daniel101191,
From your stats it looks like you are on a TalkTalk package provided over BT's wholesale network, as opposed to TalkTalk LLU.
Generally speaking, BTW access provides the worst form of ADSL service; not because it involves 'slow' (in terms of sync speed vs. attenuation) ADSL1 modulation but I think a result of relatively expensive 20CN bandwidth which effectively results in ISPs underprovisioning their subscribers and having to resort to very unfriendly traffic management policies.
Not only this, but unfortunately an additional degree of rate limiting is employed on the BT Wholesale 20CN and 21CN networks - the IP Profile. It doesn't always work as it should and, if I were experiencing "slow downloads", is the second thing I would check after making sure the modem sync rate was okay. Check your IP Profile using BT's
speedtest site - in your case it should be around 1000 kbps less than your sync rate. The IP Profile effectively defines your maximum download speed. If your BT speedtest result is less than the IP Profile this indicates the worst case - the network is just congested.
With respect to the question in your original post, I didn't understand it clearly enough to attempt a response.
