Apple Performa 550 Wifi
It will be easier to buy a new wireless USB adapter and just plug it in, than to replace any built-in adapter your desktop may have. WiFi, or wireless internet, uses a piece of hardware in order to connect to your home network. A lot of newer wireless adapters are plug-n-play, in that you just plug it in the USB port and the OS will install the drivers on its own. Finding a WiFi adapter is easy because the only thing you have to know is the current operating system on your Apple desktop.
What to see if the wireless internet adapter has gone bad?
- Your wireless internet connection goes out randomly over and over again
- Your WiFi in your Apple desktop is unable to find a signal from your router
- The wireless adapter driver shows it as not installed
