I have just had a proper openreach engineer over and the problem with my line running at 57 mbps download and 11 mbps upload was due to the Quinns engineer not fitting an SSFP Infinity master socket.
The OR engineer fitted a new SSFP master socket and reset my profile, I am now getting speeds of 76 mbps download and 20 mbps upload, I am now happy!
Anyone upgrading to Infinity 2 needs to make sure you have a proper SSFP Inifity socket installed to get max speeds.
If anyone needs any advice on how to handle BT in this matter drop me a PM, I am happy to help.
