- A
Enable 'Wi-Fi calling' to offload calls to cellular.
Why wrong: Wi-Fi calling is for voice calls, not for maintaining data connection stability.
- B
Set the device to 'Keep Wi-Fi on during sleep' to 'Always'.
Why wrong: This setting keeps Wi-Fi on when the screen is off, but the issue occurs while moving, not during sleep.
- C
Disable 'Wi-Fi power saving mode' in the advanced Wi-Fi settings.
Power saving mode can throttle the Wi-Fi radio to save battery, causing drops when the signal weakens; disabling it keeps the radio at full power.
- D
Change the Wi-Fi frequency band from 5 GHz to 2.4 GHz.
Why wrong: While 2.4 GHz has better range, the issue is intermittent drops, not range; changing bands may not solve the power management problem.
Question 605 of 1,020
Fix Wi-Fi Disconnects by Disabling Power Saving Mode
This 220-1201 practice question tests your understanding of mobile device network connectivity. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A user's smartphone intermittently drops Wi-Fi connection when the device is moved from one room to another. The home uses a single Wi-Fi router. The technician suspects the issue is related to the device's power management. Which setting should be adjusted to maintain a stable connection?
Quick Answer
The answer is to disable Wi-Fi power saving mode in the advanced Wi-Fi settings. This setting is the culprit because it throttles the Wi-Fi radio’s power and scanning frequency to conserve battery, which directly causes the connection to drop when you move between rooms and the signal strength changes. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of mobile device power management and its impact on network connectivity; a common trap is to blame the router or suggest changing channels, but the issue is device-side. Remember the memory tip: “Power save cuts the wave, so moving rooms won’t behave.”
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
✓
Disable 'Wi-Fi power saving mode' in the advanced Wi-Fi settings.
Option C is correct because disabling 'Wi-Fi power saving mode' prevents the device from reducing radio power or entering low-power states when moving between rooms, which can cause intermittent signal drops. This setting directly addresses the power management behavior that leads to unstable connections during transitions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable 'Wi-Fi calling' to offload calls to cellular.
Why it's wrong here
Wi-Fi calling is for voice calls, not for maintaining data connection stability.
- ✗
Set the device to 'Keep Wi-Fi on during sleep' to 'Always'.
Why it's wrong here
This setting keeps Wi-Fi on when the screen is off, but the issue occurs while moving, not during sleep.
- ✓
Disable 'Wi-Fi power saving mode' in the advanced Wi-Fi settings.
Why this is correct
Power saving mode can throttle the Wi-Fi radio to save battery, causing drops when the signal weakens; disabling it keeps the radio at full power.

Read the scenario before looking for a memorised answer.
- ✗
Change the Wi-Fi frequency band from 5 GHz to 2.4 GHz.
Why it's wrong here
While 2.4 GHz has better range, the issue is intermittent drops, not range; changing bands may not solve the power management problem.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The 220-1201 exam often tests the distinction between power management settings (like Wi-Fi power saving mode) and connectivity settings (like band selection or sleep behavior), trapping candidates who confuse range-related fixes with power-saving adjustments.
Detailed technical explanation
How to think about this question
Wi-Fi power saving mode, often implemented via 802.11 power save polling (PS-Poll) or WMM Power Save, allows the device to enter a doze state between beacon intervals to conserve battery. When moving between rooms, the device may incorrectly interpret signal fluctuations as an opportunity to reduce power, causing brief disconnections. Disabling this mode forces the radio to remain active, maintaining a consistent connection even during transitions.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
