ADSL faster than FTTC

Hello, I am looking for some advice on a problem I have with my flat and I can't seem to find an answer. I currently have ADSL and I get a speed of 14Mb I had FTTC last year and the top speed I could get was 12Mb. Excuse my ignorance but does that sound right? I thought with 14Mb ADSL I would get 40-50Mb FTTC?

Despite EE saying it was strange when downgrading me they do not seem to think there is anything I can do. Does anyone know if this indicates a fault and if so who I should be talking too?

That's not how it works.

ADSL speed is dependant on distance to the telephone exchange.
FTTC speed is dependant on distance to your local green phone cabinet.

There's no direct correlation between ADSL and FTTC speeds.

That's great, thanks for clearing that up.

It could be correct, although there is no direct correlation. My ADSL is 12mb but VDSL would be 9mb.
Have you checked availability and forecast speeds on BT.com for both products.

Yes with my phone number is it 14Mb ADSL and 12Mb FTTC on BT, EE ect.

Line OK just unfortunate positioning of fibre cabinet. Distance between cabinet and you does not give any speed benefit, VDSL loses more speed per metre than ADSL.

VDSL2 is designed to provide equivalent throughout to ADSL2+ on longer lines, but Openreach is not permitted to use the required frequencies because they are reserved for exchange-based ADSL2/+.

Without that restriction, the throughout would be improved simply because the VDSL2 DSLAM is closer to the premises than the exchange DSLAM. It�s frustrating that legacy infrastructure causes newer technologies to run sub-optimally.
