I would like to connect my Kindle Fire and Windows Surf to the internet using WiFi (neither device has an enernet port or CD player). The room I am renting has a modem. I bought a Netgear WiFi. The first thing the directions say is to install the CD that comes with it. As I said, neither divice had a CD, so do I take th Netgear WiFi back to the store or will it work by connecting it to the modem and forget about the CD that came with it?
