I connected to VM in October for the 20meg service.
I get 15-18meg in the morning, and then it sloooowzzzz down to Under 1meg after 6pm. Ive had an engineer call. Didnt make any difference.
Anyway....
Try Be Unlimited Broadband. I have VM but I had to get another service. Be Unlimited is ADSL2+ and is up to 24meg. Im getting 10meg and it costs £18 a month - I also get a good 1.3meg Upload (2x faster than VM).
My Virgin Broadband is 20meg but only get anything like that in the early hours. After 6pm I get less than ONE MEG connection!!!
Be Unlimited is at

Good Luck...
