Apple MC561LL-A Wifi
It will be easier to buy a new USB adapter and just plug it in, than it is to replace any type of OEM adapter you might have. The WiFi in your desktop, if so equipped, uses an adapter in order to talk to your router and modem. Buying a wireless adapter is quite easy because all you need to know is what OS you are running on your Apple MC561LL-A. Most new Wifi adapters are simply plug and play, which means you simply plug it into a USB port and the OS will install the drivers on its own.
Signals the WiFi adapter should need replacing
- Your wireless internet connection disconnects itself all the time
- The wireless adapter in your Apple desktop is unable to connect to the internet
- The desktop wireless driver suddenly shows as uninstalled
