The upgrade to Aberdare looks to be to provide the "superfast" broadband that there is a lot of fuss about. Called Fibre To The Cabinet, (FTTC). BT's product using this is Infinity, but many ISPs offer FTTC products as well, just like on ADSLx broadband.
You can read what all that is about on this page
If you put your phone number into this checker
it will give you more information. It would be useful if you copy/post what it says so we can explain anything you aren't clear about. I would expect you would have a dramatic improvement if you moved to it.
It isn't something that happens automatically. It's a new range of products, so you have to upgrade or migrate to another ISP.
Which ISP are you with, what package, and how much do you pay?
