220-1102 Practice Question: A small business owner reports that after…
A small business owner reports that after upgrading their wireless router to a newer model, their older laptops running Windows 7 cannot connect to the Wi-Fi network. The new router is configured with WPA3-Personal. Which of the following is the most likely reason for the connectivity failure?
⚠ Common exam trap
CompTIA often tests the misconception that older Windows 7 laptops can connect to any Wi-Fi network as long as they have the password, but the trap here is that WPA3 requires both hardware and driver-level support, which legacy adapters lack.
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 laptops' wireless adapters do not support WPA3.
WPA3-Personal is a newer wireless security protocol that requires hardware support in the wireless adapter. Older laptops running Windows 7 typically have legacy wireless adapters that only support WPA2 or earlier protocols. Since the router is configured to use WPA3 only, the laptops' adapters cannot negotiate a connection, resulting in failure.
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 is hidden.
Why it's wrong here
A hidden SSID would prevent the network from appearing in the list, but the laptops can still connect manually; this is not specific to the security protocol version.
- ✓
The laptops' wireless adapters do not support WPA3.
Why this is correct
WPA3 is a newer security standard; older hardware and drivers often lack support, forcing a fallback to WPA2 or causing connection failures.
- ✗
The router is broadcasting on a 5 GHz band only.
Why it's wrong here
While older laptops may lack 5 GHz support, this is a band compatibility issue, not a security protocol issue; the scenario specifically points to the security upgrade.
- ✗
The laptops have incorrect DNS settings.
Why it's wrong here
Incorrect DNS would cause browsing issues after connection, but would not prevent the initial Wi-Fi association and authentication.
