Do I Have A Stuck Profile?

I recently (2nd April 07) transferred my ISP from Homecall-Pipex to BT. I transferred because of poor service & H-P's inability to deliver me an 'Up to 8mb' service.

As my new BT Home Hub router had not arrived at first I started out with my 'old' KCorps one. I went over to the Homehub when it arrived a couple of days later. However my IP profile has been exactly 2000 kbps ever since first connected by BT. Speed tester results have largely remained unchanged throughout, eg:

Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 2000 kbps
DSL connection rate: 448 kbps(UP-STREAM) 8128 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 1818 kbps

Router stats are below - are these good numbers? I live approx 1 mile from the exchange. BT Helpdesk came across as if they had never heard of a stuck profile & say 2000kbps is all my line can support. I hope someone can advise if this is a stuck profile &, if so, I'll get back onto BT? (OS is XP)

Yes, unless you have sync'ed under 2848 in the last three days. You always have to kick and kick and kick until you get someone who understands what you are talking about. You should be on 7150 profile.
