I recently had fibre optic with talktlak installed and wanted just one piece of kit to replace the open reach modem and talktalk wireless router. After looking around the web I decided to go for the Fritz!Box 7390.
It's probably the most expensive solution but after having used it now for over a week I can see why it is worth every penny.
This is by far the best router/modem I've had and it's the easiest to add peripherals.
Even setting up a static ip is a breeze.
