Hold the Wi-Fi card down with your finger.

Position the black antenna cable connector over the left Wi-Fi card's coaxial socket.

Tweezers can help position the connector.

Use your finger to press the connector into place. You should feel a faint click, and the cable will stay attached to the socket by itself.

These connectors are very delicate! If the connector doesn't feel like it's clicking in place, reposition the connector and try again.

Repeat the procedure with the white antenna cable.
