BT I-Plate promises to speed up ADSL connections by up to 60%; will it work for you?

If you are fitting an iPlate there is no need to remove ring wires.

On the BTw system you get set an "IPprofile rate" based on the sync rate ....

Unfortunately moving from 2.9 to 3.2 Mbps sync won't result in any increase but the move was still beneficial as you are less likely now to drop back into a lower band
