A technician recently replaced a user ' s laptop screen. Since then, the user has had trouble connecting to wireless networks. Which of the following should the technician do?
A.
Verify that wireless technologies are compatible with the updated hardware.
B.
Reinstall the wireless drivers after the OS is reloaded.
When a laptop screen is replaced, the technician typically removes the display bezel and may disconnect cables routed through the hinge area. The Wi-Fi antennas in most laptops are mounted inside the display assembly (often along the top edges of the screen) and their thin coax antenna leads run through the hinges to the wireless adapter connection points on the system board or directly onto the Wi-Fi card (MAIN/AUX terminals). If one or both antenna leads are left unplugged, pinched, or poorly seated during reassembly, the laptop will still detect the Wi-Fi adapter, but wireless performance will be severely degraded—weak signal strength, intermittent connections, inability to see networks reliably, or frequent dropouts.
This symptom appearing immediately after a screen replacement strongly indicates a physical antenna connection issue rather than a driver or software problem. Reinstalling drivers or resetting services would be more appropriate after OS changes or configuration corruption, not after display hardware work. Compatibility of wireless technologies is unrelated to swapping a screen. Therefore, the best CompTIA A+ troubleshooting step is to open the unit and reconnect/secure the Wi-Fi antenna leads to the system board/wireless card.
