Apple MD712LL-A Wifi
It is much simpler to buy a new wireless USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Most new Wifi adapters are simply plug and play, in that you just plug it in the USB port and the OS will handle everything from there. The WiFi in your laptop, if so equipped, makes use of a wireless adapter in order to talk to your home router. Buying a wireless adapter is quite easy because the only thing you have to know is the current operating system on your Apple MD712LL-A.
Key clues to watch for in a bad WiFi adapter
- The wireless adapter driver shows it as not installed
- The wireless adapter in your Apple laptop is unable to find a signal from your router
- Your wireless internet connection drops multiple times throughout the day
