220-1201 Practice Question: A customer reports that their laptop frequently…
A customer reports that their laptop frequently disconnects from the Wi-Fi in their home office, but works fine in other rooms. The office is located in a detached garage, and the wireless router is in the main house. Which wireless networking technology would best solve this issue without running cables?
⚠ Common exam trap
The CompTIA A+ exam often tests the misconception that upgrading to a newer standard (like 802.11ac) or switching to 5 GHz alone will fix range issues, when in fact these technologies are more susceptible to attenuation and require a strong signal to deliver their benefits.
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
✓
Wireless mesh network
A wireless mesh network is the best solution because it extends Wi-Fi coverage to the detached garage without running cables. Mesh nodes communicate wirelessly with each other, creating a seamless network that overcomes the range and obstruction issues caused by the distance and building materials between the main house and garage.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
5 GHz frequency band
Why it's wrong here
5 GHz has shorter range and is worse at penetrating walls, so it would not improve connectivity to a detached garage.
- ✓
Wireless mesh network
Why this is correct
Mesh networks use multiple access points to blanket an area with seamless coverage, perfect for extending Wi-Fi to a separate building.
- ✗
Powerline networking adapters
Why it's wrong here
Powerline uses electrical wiring, not wireless, and may not work reliably across separate buildings on different electrical panels.
- ✗
802.11ac standard
Why it's wrong here
802.11ac operates mainly on 5 GHz and offers high speed but not the extended range needed for this scenario.
