Explanation

Laptop wireless antenna wires are thin coaxial cables that run from the wireless card (located in the laptop base) up through the hinge and into the display bezel, where they attach to the antenna. Replacing the display requires disconnecting these antenna cables. If they are not reconnected after reassembly, wireless functionality will fail. This is the most common oversight during display replacement. A damaged wireless switch (A) or failed network card (B) would be unlikely to occur from a display swap. Displays do not emit signals that interfere with Wi-Fi (C).
