CompTIA 220-1201 Dumps Questions Answers

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.

When port issues persist after moving to a different switch port, the next logical troubleshooting step is to test the patch cable. Faulty or damaged cables are a common cause of network connectivity problems. Using a cable tester between the computer and the network closet verifies the integrity of the cable and rules out a physical layer issue.

From CompTIA A+ 220-1101 Official Study Guide, Objective 4.2 – Troubleshoot wired and wireless networks:

“If a device continues to experience connectivity issues after switching ports, test the cabling with a cable tester to check for continuity, shorts, or pinout issues before replacing hardware.”
