Apple MacBook Pro ME864LL-A Wifi
The WiFi in your laptop, if so equipped, uses a piece of hardware in order to connect to your wireless router or modem. Most new Wifi adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the operating system will take care of the rest. It is cheaper and easier to purchase a new USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Searching for a new adapter is simple because the only thing you have to know is what OS you are running on your laptop.
Major indications the WiFi adapter is on its last leg
- The wireless adapter in your Apple laptop is unable to connect to the internet
- The laptop wireless driver gives errors when installing
- Your wireless internet connection goes out randomly all the time
