Apple MD389LL-A Wifi
The WiFi in your desktop, if so equipped, uses an adapter to send and receive signals to and from your router and modem. A lot of newer wireless adapters are plug-n-play, in that you just plug it in the USB port and the operating system will take care of the rest. Buying a wireless adapter is quite easy because all you need to know is what OS you are running on your Apple MD389LL-A. It is cheaper and easier to purchase a new wireless USB adapter and install it, than it is to replace any type of OEM adapter you might have.
