Insert an arm of your angled tweezers under the metal neck of one of the coaxial connectors on the Wi-Fi card and lift straight up to disconnect it.

Repeat for the other connector.

During reassembly, use tweezers to hold the connector in place over its socket and gently press down with your finger or a spudger—the connector should "snap" into place. If you're having trouble, reposition the head and try again.
