Do I need to buy any additional materials in order to use the Wi-Fire?
No. The Wi-Fire is ready to go out of the box. No additional materials or work is necessary! The Wi-Fire doesn’t even require you to already have an internal WiFi network card in your computer. Though if you do already have an internal WiFi network card (of any type, including 802.11n), there is no interference between it and the Wi-Fire, so you won’t need to modify any of your existing settings.
