My infinity is fine too but there are some things to be wary of.
1 It is not really reliable enough for TV compared to say Sky, by this I mean that while I get 75Mbs on my LAB connected PC my wife's WIFI connected PC never gets more than 25 and that can be very variable.
2. A lot of BT engineers-they are only technicians not engineers as in professional engineers, do not work for BT but are contractors and they do not know much more than how to putt he connection together in your home-if there is a problem they cannot help.
3 BT Customer service in India is worse than useless - find an email address for executive level complaints-they have usually helped me.
Finally good luck its not a bad product when it gets going but BTs support is pretty poor
