Replace wireless cards, antennas, and related modules for A+
Short answer
Wireless hardware replacements usually involve removing a small module from a slot and reconnecting one or more tiny antenna leads. Handle coax connectors carefully using a steady pull and avoid twisting. Confirm antenna leads are correctly seated and routed, and that screws are present to secure the module.
Why it appears on the exam
- Choose the correct next step after removing a wireless card: reseat antenna leads and secure the module, then power on to confirm hardware detection. - Identify why a replacement wireless card might still show poor performance: antenna leads not connected or damaged.
Key concepts
Concept 1
Required terms
wireless card: A small module providing Wi-Fi or Bluetooth functionality in laptops; often removable in a mini-PCIe or M.2 slot. antenna lead: Thin coaxial cable or spring pin lead that connects the wireless card to the device antenna; connectors are small and delicate. wireless card: removable radio module in laptop devices. antenna lead: tiny coaxial connectors that require gentle handling.
Example
Replacing a laptop M.2 wireless card and ensuring the MAIN and AUX antenna connectors are reseated in their labeled posts.

How Replace wireless cards, antennas, and related modules works
Wireless hardware replacements usually involve removing a small module from a slot and reconnecting one or more tiny antenna leads. Handle coax connectors carefully using a steady pull and avoid twisting. Confirm antenna leads are correctly seated and routed, and that screws are present to secure the module.
Example
Replacing a broken antenna lead and verifying that the wireless hardware is visible to the OS before handing over to networking troubleshooting.
Concept 3
Common confusion
Mixing hardware and software responsibilities. A correct repair answer focuses on reconnecting antenna leads and confirming hardware visibility; it does not attempt to fix SSID or authentication issues as part of the hardware replacement micro-objective.
Example
Replacing a laptop M.2 wireless card and ensuring the MAIN and AUX antenna connectors are reseated in their labeled posts.
