Is there any special reason why you are looking for a VDSL modem/router?
These are thin on the ground so a much wider choice is available using the modem provided by OR and just use a "normal" router which has a WAN input?
I use a Billion 7800 which has good wifi and all the functionality I require (and which I already had during my days with BE). Previously used a Draytek 2820 which was an excellent piece of kit but isnt fast enough for an 80/10 FTTC service running at full speed. My daughter at university is using it as a wireless access point on her hall of residence network instead.
BT Infinity 2 - IP profile 77 / 20 - super fast!
