Well it seems my migration from Plusnet to BT Infinity 2 (76Mbps) happened at 7am this morning with the BT comfirmation email sent shortly afterwards. The only thing is, my sync speed for well over a year has been around 68Mbps but is now a full 10 meg lower at 58Mbps.
I'm using the same Billion 8800NL modem and nothing else has changed. I noticed that the SNR is now 5.6 when it's usually around 6.1.
Is the sync likely to increase?
