Have a read of this thread linked below asking a similar question.
Edit ~ Disregard my post and follow the advice below by @Tony-D from the NowTV Team.
I am soon to go live with Now - Is it possible to continute to use my hi-spec Netgear router? Apart from anything else, I need more than the 2 physical network connectors supplied on the Now router.
Shouldn't really be a problem @MckCol but obviously we wouldn't be able to provide any help if something goes wrong within the set up.
