A user wants to connect a laptop to a corporate wireless network. What internal component must be present in the laptop?
⚠ Common exam trap
It's easy for candidates to confuse Bluetooth and Wi-Fi because both use 2.4 GHz radio frequencies, but Bluetooth is designed for short-range device pairing (e.g., keyboards, mice) and cannot authenticate to a corporate wireless network using 802.1X or WPA3-Enterprise.

Correct answer & explanation
✓
Wireless NIC
A Wireless NIC (Network Interface Card) is the internal component required for a laptop to connect to a corporate wireless network. It contains a radio transceiver that communicates with wireless access points using IEEE 802.11 standards (e.g., 802.11ax), handling frame encapsulation, authentication, and encryption such as WPA3. Without a wireless NIC, the laptop has no physical layer capability to transmit or receive Wi-Fi signals.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Wireless NIC
Why this is correct
A wireless NIC provides the radio and 802.11 firmware needed to associate with an access point, satisfying the stem's requirement for an internal component. Without it, the laptop has no physical means to transmit or receive Wi-Fi frames, so no corporate wireless connection is possible.
- ✗
Cellular modem
Why it's wrong here
A cellular modem connects to mobile carrier networks via licensed radio spectrum, not to an organisation's Wi-Fi access point using 802.11 frames and WPA authentication. It is tempting because it provides wireless internet, but it is the right component for connectivity over 4G or 5G where no Wi-Fi exists.
- ✗
Infrared port
Why it's wrong here
An infrared port provides short-range line-of-sight data transfer, not radio connectivity to a Wi-Fi access point, so it cannot join a corporate wireless network. Infrared suits legacy device-to-device links such as syncing a PDA, which is why it appears plausible as a wireless component.
- ✗
Bluetooth adapter
Why it's wrong here
A Bluetooth adapter creates short-range personal-area networks for peripherals like headsets and mice; it does not implement the IEEE 802.11 radio and authentication needed to associate with a corporate wireless network. Bluetooth is correct for pairing nearby accessories, not for Wi-Fi infrastructure access.
