Exhibit
Laptop status: Associated to CorpWiFi, signal strong AP dashboard: client joined successfully Client shows APIPA address 169.254.22.14
Exhibit: A wireless client can see the SSID and associates successfully, but it never gets network access. Other users on the same SSID work. Which issue is the best fit?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
The AP is advertising the wrong channel width
That would affect RF performance more broadly, not just one associated client getting no network access.
B
Best answer
The client failed to obtain a valid IP address from DHCP
Association without a working IP configuration is a classic symptom.
C
Distractor review
The SSID must be changed from broadcast to hidden
A hidden SSID would not fix this.
D
Distractor review
WPA2 automatically blocks clients until NTP is configured
That is not how WPA2 client access works.
Common exam trap
Common exam trap: answer the scenario, not the keyword
A common exam trap is to assume that successful association guarantees full network access, leading to incorrect answers like channel width or SSID broadcast settings. Candidates may also mistakenly believe that WPA2 authentication blocks clients until NTP is configured, which is false. The key mistake is confusing wireless Layer 2 connectivity with Layer 3 IP addressing. Since other clients on the same SSID work, the problem is client-specific and related to DHCP failure, not wireless configuration or security settings. Recognizing this distinction avoids wasting time on irrelevant options.
Technical deep dive
How to think about this question
Wireless client association to an SSID confirms that the client has successfully completed Layer 1 (radio frequency) and Layer 2 (MAC) connection processes with the access point. This means the client and AP have agreed on wireless parameters and security settings, allowing the client to join the wireless network segment. However, association alone does not guarantee that the client can communicate beyond the local wireless link or access network resources. Once associated, the client must obtain a valid IP address to communicate on the network. This is typically done via DHCP, which dynamically assigns IP addresses and other network parameters. If the client fails to receive a DHCP lease, it will not have a valid IP address, subnet mask, or default gateway, preventing it from accessing network services despite successful association. This failure is often client-specific and does not affect other users on the same SSID. The exam trap here is to confuse Layer 2 association issues with Layer 3 addressing problems. Since other clients on the same SSID work fine, the wireless infrastructure and SSID configuration are correct. The client’s inability to get network access is almost always due to DHCP failure or IP misconfiguration. Hidden SSIDs or WPA2 authentication settings do not cause this symptom, and channel width settings affect RF performance broadly, not just one client’s IP configuration. Understanding this layered troubleshooting approach is critical for CCNA success.
KKey Concepts to Remember
- A wireless client successfully associating to an SSID means the Layer 1 and Layer 2 wireless connection is established but does not guarantee Layer 3 network access.
- DHCP assigns IP addresses dynamically, and failure to obtain a valid DHCP lease prevents the client from communicating on the network beyond association.
- Other clients successfully accessing the network on the same SSID indicate the wireless infrastructure and SSID configuration are correct and not the root cause.
- SSID broadcast visibility allows clients to discover the network; hiding the SSID does not affect DHCP or IP address assignment processes.
- WPA2 authentication controls client access at Layer 2 but does not block clients based on NTP configuration or time synchronization settings.
- A client failing to get network access after association typically suffers from IP addressing issues such as DHCP failure or static IP misconfiguration.
- Troubleshooting wireless client connectivity requires verifying DHCP lease acquisition and IP configuration after confirming successful association.
- Network Access in CCNA includes understanding how wireless clients obtain IP addresses and how DHCP failures manifest as connectivity issues.
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.

FAQ
Questions learners often ask
What does this 200-301 question test?
A wireless client successfully associating to an SSID means the Layer 1 and Layer 2 wireless connection is established but does not guarantee Layer 3 network access.
What is the correct answer to this question?
The correct answer is: The client failed to obtain a valid IP address from DHCP — Successful association means the radio connection is up. If only one client fails to get network access while others work, the most likely issue is a client-specific addressing problem such as not obtaining a valid DHCP lease.
