Quick Answer
The answer is an incorrect IP configuration. This is the most likely cause because the laptop has successfully established a Layer 2 Wi-Fi connection, as shown by the "connected" status, but it cannot reach the internet, which requires proper Layer 3 (network layer) settings. Without a valid IP address, default gateway, and DNS server—whether due to a failed DHCP lease or a static IP in the wrong subnet—the device can associate with the access point but cannot route traffic beyond the local network. On the CompTIA ITF+ FC0-U61 exam, this scenario tests your understanding of the OSI model layers, specifically distinguishing between physical/data-link connectivity (Layer 1/2) and network layer configuration (Layer 3). A common trap is to blame the Wi-Fi signal or the access point, but since other users are connected fine, the issue is isolated to the laptop’s network settings. Memory tip: think "Wi-Fi bars don't mean internet bars"—Layer 2 is happy, but Layer 3 is broken.
This FC0-U61 practice question tests your understanding of infrastructure. 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 reports that their laptop cannot connect to the corporate Wi-Fi network. Other users in the same area are connected without issues. The laptop shows it is connected to the Wi-Fi but has no internet access. Which of the following is the MOST likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Weak Wi-Fi signal
Why wrong: Weak signal usually results in no connection or disconnections.
SSID broadcast disabled
Why wrong: SSID hidden would not allow the network to appear in list.
Incorrect IP configuration
Static IP or wrong DHCP settings can cause local connectivity but no internet.
MAC address filter enabled
Why wrong: MAC filter would block association entirely.

Correct answer & explanation
Incorrect IP configuration
The laptop shows it is connected to Wi-Fi but has no internet access, which indicates that the Layer 3 (network layer) configuration is faulty. An incorrect IP configuration, such as a static IP in the wrong subnet or a failed DHCP lease, prevents the laptop from obtaining a valid default gateway and DNS server, breaking internet connectivity while the Wi-Fi association (Layer 2) remains intact.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Weak Wi-Fi signal
Why it's wrong here
Weak signal usually results in no connection or disconnections.
SSID broadcast disabled
Why it's wrong here
SSID hidden would not allow the network to appear in list.
Incorrect IP configuration
Why this is correct
Static IP or wrong DHCP settings can cause local connectivity but no internet.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

Why it's wrong here

Common exam traps
The trap here is that candidates confuse a successful Layer 2 association (connected to Wi-Fi) with full Layer 3 connectivity, leading them to choose weak signal or MAC filtering instead of recognizing that the issue is at the IP configuration layer.
Detailed technical explanation
When a client connects to Wi-Fi but has no internet, the most common cause is a DHCP failure, where the client receives an Automatic Private IP Addressing (APIPA) address (169.254.x.x) or a stale static IP that does not match the corporate subnet. The laptop's IP stack must have a valid IP, subnet mask, default gateway, and DNS server to route traffic beyond the local network; a misconfiguration at this layer will pass Layer 2 connectivity checks but fail all internet-bound traffic.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
