220-1201 Practice Question: That their laptop can see several neighboring…
A user reports that their laptop can see several neighboring Wi-Fi networks but cannot see their own office's SSID, which is a 5 GHz-only network. Other users in the same office can connect without issue. What is the most likely cause?
⚠ Common exam trap
CompTIA A+ exams often test the misconception that encryption or SSID broadcast settings are the cause when the real issue is frequency band incompatibility, leading candidates to overlook the adapter's hardware limitations.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The laptop only supports 2.4 GHz Wi-Fi.
The user's laptop can see neighboring 2.4 GHz networks but not the office's 5 GHz-only SSID, while other users connect fine. This indicates the laptop's wireless adapter lacks 5 GHz support, making option C correct because 5 GHz-only networks are invisible to 2.4 GHz-only adapters.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The router's SSID broadcast is disabled.
Why it's wrong here
If broadcast were disabled, no user would see the SSID, but others can see it.
- ✗
The laptop's wireless adapter is set to airplane mode.
Why it's wrong here
Airplane mode would disable all wireless, and the user would not see any networks.
- ✓
The laptop only supports 2.4 GHz Wi-Fi.
Why this is correct
If the adapter lacks 5 GHz capability, it cannot detect a 5 GHz-only network, explaining why other users (with 5 GHz support) can connect.
- ✗
The office router is using WPA3 encryption.
Why it's wrong here
WPA3 is backward compatible and does not prevent network discovery; it only affects authentication.
