|NIC = Network Interface Card. Unless your laptop is extremely old, you already have one installed.|
Media = CD or DVD disc.
Is the wireless on the laptop enabled? Are the wireless drivers installed? Is the wireless icon showing in the notification area? See this pic: wireless icon
The drivers would be on the media (CD or DVD disc), or you can go to the laptop manufacturer's website to download them. It's tough to help when you don't list the make/model of your laptop or which version of Windows you're using. "Windows 64" could be XP, Vista, 7, 8, or 10.
