Should my download speeds be better?

Upgraded to Max on 5th May. Line has remained totally stable at 8128/448 since day one, no dropped connections or re-synchs at all. BT said I should be able to receive up to 6.5 Mbps. I live about 1 Km from the exchange.

Line stats are downstream attenuation 25dB / noise margin 10-12dB (Netgear DG 834). Max download recorded (BT speed test) 1980 kbps, confirmed by other download testers, including tests done in the 'wee small hours'

I have used 3 diferent routers and three different PC's, all with the same results.

I entered a dialogue with BT tech support via e-mail over 3 weeks ago (I thought I would avoid phoning due to all the negative feedback in these forums) but the results seem to be the same. The last response took 6 days to arrive. No-one seems to address the technical issues, assuring me that this is maximum my line can support.
Is this true or should or should I expect better download speeds at least some of the time?

Thanks,
Bob

Use www.speedtest.bbmax.co.uk

the bt one isn't very reliable!!!

Thanks. Tried that one (and some others) over the past few weeks. None have shown a speed above 2000kbps.
