MacBook Wi-Fi Card and Antenna: The Right Part for Your Mac
When Wi-Fi or Bluetooth keeps dropping, or disappears from the settings, the fault may come from the Wi-Fi card (AirPort card), the antenna, or the AirPort bar that carries it. Here is the part that matches your Mac.
Before replacing a part
- Restart the Mac and the router, then try another Wi-Fi network.
- Check System Settings > Wi-Fi: if Wi-Fi no longer appears at all, the card or its antenna is the cause.
- After a screen or case repair, check that the antenna cables are properly reconnected.
On recent MacBooks, the Wi-Fi chip is soldered to the logic board: only the antenna or the AirPort bar can be replaced.

Frequently asked questions
Does Bluetooth use the same card?
Yes, on the Macs concerned, the AirPort card handles both Wi-Fi and Bluetooth.
What is the AirPort bar?
It is the part that carries the Wi-Fi antennas, often under the display hinge. A pinched or cut cable there makes the signal drop.
