Help with broadband

Hi, I have recently been looking to switch my broadband provider in an attempt to speed up my conection. I have been looig at a lot of their websites to check the speeds they offer and the best that I can receive at my current location is 0.5mb. I was wandering if it is possible to increase this? I live at postcode BN86LJ, and my nearest exchange is about 500 metres down the road.

Thank You Sam.

I looked your postcode up on the postcode checker at your guide to Broadband in the UK - broadband.co.uk and it says that 0.5Mbps is the maximum you can get, so it sounds like you are a bit stuck for getting anything faster :S
