Hi Adam The line;
ADSL Link Downstream Upstream Connection Speed 4896 kbps 448 kbps
Does that mean my line is capable of that, because I have never had over 1Mb?

Yes you should get 4M ( you lucky sod!!! :) See http://www.plus.net/support/broadband/products/faqs_and_guides/dslmax_guide.... for line speed to BRAS conversion. The BRAS is BT's lowest stable line speed ie the speed of your connection can go up and down a bit, so instead of creating an "error state" each time it takes the lowest speed and "rounds down".
I think that at the setup time your BRAS rate did not change. Use the BT speed tester www.speedtester.bt.com as this also gives the BRAS rate ( IP profile ). If you have no luck over the next few days then if you have used this speed tester over several times over several days then your ISP can kick the BRAS profile for you.
