Apple MacBook Pro MD212LL-A Wifi
Buying a USB wireless adapter is quick and painless because the only thing you have to know is what OS you are running on your Apple MacBook Pro MD212LL-A. It is much simpler to buy a new USB adapter and install it, than to replace any built-in adapter your laptop may have. WiFi, or wireless internet, uses a piece of hardware in order to talk to your router and modem. Most USB wireless 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.
Major clues your wireless internet adapter needs replacing
- The wireless adapter driver shows it as not installed
- Your WiFi on your laptop is unable to find a signal from your router
- The WiFi drops for no reason all the time
