Use a plastic opening tool to remove the Wi-Fi wires from their sockets on the motherboard.

Remove the wires from the hooks around the motherboard and fan cover to completely remove the antennas.

The Wi-Fi antennas' ports are labeled B and W on the motherboard for reassembly.

To insert your new Wi-Fi antennas, insert the wires of your replacement Wi-Fi antennas into each socket, feed the wires through the hooks, and install the antennas on their mount.
