220-1201 Practice Question: That their laptop's Wi-Fi connection drops every…
A user reports that their laptop's Wi-Fi connection drops every 10 minutes, but reconnects immediately. The technician notices that the laptop is connected to a 5 GHz SSID. What is the most likely cause?
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 user is at the edge of the 5 GHz coverage area.
5 GHz signals have shorter range and are more easily obstructed. If the user is at the edge of coverage, the signal may intermittently drop. The periodic nature suggests a weak signal, not interference or driver issues.
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The laptop's Wi-Fi driver is outdated.
Why it's wrong here
An outdated Wi-Fi driver typically manifests as persistent connectivity issues, complete inability to connect, or system instability (e.g., blue screens), rather than predictable, timed disconnections every 10 minutes. Driver problems usually cause a more constant or random failure pattern, not a regular, intermittent drop and re-connection cycle.
- ✗
The access point is configured with a short DHCP lease time.
Why it's wrong here
DHCP lease renewal is a background process where the client proactively requests to renew its IP address before the current lease expires. This renewal occurs via a unicast communication and does not interrupt the network connection or cause a noticeable disconnection for the user, regardless of the lease duration.
- ✓
The user is at the edge of the 5 GHz coverage area.
Why this is correct
5 GHz Wi-Fi signals have a significantly shorter range and are more susceptible to attenuation by walls and other obstacles compared to 2.4 GHz. Being at the edge of the 5 GHz coverage area means the signal strength (RSSI) is weak and prone to fluctuations, causing the laptop to periodically lose connection and re-associate as the signal briefly drops below a usable threshold.
- ✗
There is interference from a microwave oven.
Why it's wrong here
Microwave ovens operate within the 2.4 GHz Industrial, Scientific, and Medical (ISM) band, typically around 2.45 GHz. Consequently, their electromagnetic interference would only affect 2.4 GHz Wi-Fi networks, not 5 GHz networks, which utilize a distinct and higher frequency spectrum, making them immune to microwave oven interference.
