Apple MD770LL-A Wifi
Buying a USB wireless adapter is quick and painless due to the fact that all you need to know beforehand is the current operating system on your desktop. You are better off buying a common WiFi USB adapter and install it, than it is to replace any type of OEM adapter you might have. A lot of newer wireless adapters are plug-n-play, which means you simply plug it into a USB port and the system will install the drivers automatically. The WiFi in your desktop, if so equipped, uses an adapter to communicate with your router.
Major clues the WiFi adapter has little time left
- Your wireless internet connection disconnects and reconnects during the day
- The WiFi adapter driver gives errors when installing
- Your WiFi on your desktop cannot see the SSID coming from your router
