Shouldn't do bud... it's only broadband after all.
BT should install it for you (flick some switches at the exchange and roadside cabinet, do what needs doing with your wiring), then give you a nice shiny new modem/router; all you need to do is feed the settings for the Wi-fi into your computer, and Bob's the relative of your choice. If you have a desktop that connects via a network cable you stick one end in the router, one in your PC, and that's that.
Even if they do include some sort of disc with stuff on that you want to take advantage of, given the number of laptops and things out there with no optical drives at all, it should all be available online too.
