I'm sure it will be better. The wiring sounds optimal (assuming you've no unfiltered extensions). I think I'd be optimistic that you'll do notably better with ADSL2+. My benchmark is if it's good enough to stream an HD channel on iPlayer without stuttering. My experience is that it needs about 6-7mbps to be reliable.

In reply to a post by Oliver341:

Yep, it also says 'Modulation: G.992.1 Annex A', i.e. ADSL.

Yes, it does but exchange has WBC ADSL2+ DSLAMs. Puzzling?

Perhaps OP has only bought an 'Up to 8 Meg' ADSL Max service from their ISP?

Or is it that the ADSL2+ DLM has degraded the connection to ADSL1? But then the upstream would still be about 1 Meg.

Looks like you are running on ADSL Max (from UP Sync of 448K) at an exchange that supports ADSL2+.

Even so you should be getting 5.5 Meg now and you might get 6.4 Meg on ADSL2+ from either BTw or TT.

I was also puzzled.What should we do¡¿

Spoke to BT today, they weren't much help. They said that they could not set the profile to adsl2 because it was automatically selected in the first 7 days to the best stable connection available. I always thought that in the 7days it just adjusted the sync speed, so not sure if he was giving me good advice or may have not wanted to help because he could see I was leaving them!

It doesn't do either. Link.
