Got my V6 installed early this morning , it took 30 minutes from start to finish , everything seems ok, it's very fast and it can see the TiVo in the other room.
I thought I was getting a Superhub 3 ( said on my contract ) but I'm happy with my current SH2ac.
i was ripped off with my new contract, it should have included HD package so an extra £7 a month to pay.
You're better off with the SH2ac in my opinion, I have used SH3 from very early days and I am not impressed. Now just use it as a modem and manage everything else with my own router (Netgear R8500).
