A+ Lesson

Replace wireless cards, antennas, and related modules for A+

Last updated: 6/10/2026

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.

Concept 2

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.
