I want to continue using my 2910 when I switch to a VDSL line in a few months time.

Is there a DrayTek modem I can use and if not which other ones are good?

BT supply a modem so you can use that router with BT's infinity service already, the trouble with that is, the 2910's throughput is too limited to make full use of that connection speed, its throughput tops out at 20-25Mbps.

Thank you.

What would be a current Vigor router with similar functionality with VDSL?
