The logs show repeated client-association-failure events followed by RADIUS authentication failure messages for client

This means the station successfully associated at Layer 2 but failed at the RADIUS authentication step (802.1X/EAP), typically due to invalid credentials or a misconfiguration on the RADIUS server.

Eventually, the log shows a successful authentication, indicating the credentials or RADIUS issue was resolved on a later attempt.

Exhibit Analysis:

The diagram shows a section of the 5 GHz Wi-Fi band, with several adjacent channels: 149, 153, 157, 161.

The red line outlines a wider frequency range covering multiple adjacent channels (149, 153, 157).

What this means:

In Wi-Fi (especially 802.11ac/ax), “channel bonding” means combining adjacent 20 MHz channels into a wider channel (40, 80, or even 160 MHz).

The red line indicates the frequency range that would be used if an 80 MHz channel (covering channels 149, 153, 157, 161) is formed by bonding the narrower channels together.

This increases throughput because a wider channel allows more data to be transmitted at once.

Option Review:

A. Practical channel bonding to increase high throughput

Correct. The red line represents the spectrum occupied when several 20 MHz channels are bonded into a single, wider channel to increase data rates.

B. A pool of channels for the wireless radio to broadcast the wireless signal.

Incorrect. A pool would be all available channels, not the bonded range.

C. The range of channels used to allocate available airtime while transmitting data

Incorrect. This is about frequency, not time.

D. The total length of the wireless signal wavelength

Incorrect. The line indicates frequency spectrum, not wavelength length.

Summary:

The red line shows how multiple adjacent 20 MHz channels are bonded together (in this case, most likely into an 80 MHz channel), a practical method to increase wireless throughput in modern Wi-Fi networks.

When a client moves out of range, the connection drops.

The normal behavior is for the client to disconnect and then seek out and connect to another AP with a stronger signal.

The AP does not force disconnection or send alerts; the client handles roaming.

Clients do not increase their own radio power substantially in response to poor signals due to hardware limits.

FortiPresence is Fortinet’s Wi-Fi analytics/cloud presence platform.

FortiAPs can be managed directly by FortiGate or FortiLAN Cloud and connect their analytics/events to the FortiPresence cloud for presence analytics.

FortiSASE and FortiSwitch Manager do not provide FortiPresence integration for APs.

Debug Output Review:

The logs show repeated attempts to connect, with multiple msg: WPA ENTERPRISE TRANSITION and WPA NON-ENTERPRISE TRANSITION events.

There are repeated authentication frame exchanges, but several entries show failure messages, including incomplete handshake and RADIUS/authentication failures.

The client is unable to complete the full authentication process—typical indicators of incorrect credentials (failed RADIUS authentication) and failure in the WPA handshake process.

Unsuccessful association—No; the client does associate but fails at authentication/handshake.

C. Client denied after many attempts—No evidence the client itself is denying; it’s failing at the network’s authentication step.

Comprehensive Detailed Step by Step Explanation from all your Knowledge and Guides availableExhibit Analysis:

The screenshot displays two FortiAPs (FP231FT and FP23JFT) in the wireless controller’s managed APs list.

Both APs are online and connected via APs.

FP231FT shows active SSIDs (“All Tunnel Mode SSIDs”) and has 11 clients connected.

FP23JFT shows “N/A” for all SSIDs and “0” clients.

Diagnosis:

“N/A” for SSIDs on FP23JFT clearly indicates it is not broadcasting any SSID.

Both APs are running the same OS version and have their respective FortiAP profiles assigned.

Evaluating the Options:

A. Enable the radios on the FAP23JF FortiAP profile.

Correct: If the radios (2.4GHz/5GHz) are disabled in the FortiAP profile, the AP will not broadcast any SSID, resulting in “N/A” and “0 clients”. This is a common issue seen in FortiOS Wireless LAN management.

This matches the symptom, as the AP is online (communicating with the controller), but has no active radio (hence, no SSID is broadcasted).

B. Replace the FortiAP device model to match the other device.

Incorrect. FortiOS supports different models in the same deployment, as long as the correct profile is applied.

C. Disable the override setting on the FortiAP that is preventing it from broadcasting SSIDs.

Misleading. Unless an override has specifically disabled SSID broadcasting, this is not directly indicated by the screenshot. Usually, radio disabled at profile is the root cause.

D. Assign the FAP231F FortiAP profile to the problematic FortiAP device.

Incorrect. The correct profile (FAP23JF) is already assigned to FP23JFT; assigning a mismatched profile can cause more issues and is not best practice.

Guide Reference & Reasoning:

FortiOS Administration Guide – Wireless Section:

When an AP is online but SSIDs are not broadcasted and “N/A” appears for radio slots, it strongly points to the radios being disabled in the FortiAP profile (see Wireless Controller > Managed FortiAPs).

The guide explains that “If the radios are disabled in the profile, the AP will not broadcast any SSID. To resolve, enable the radios (2.4GHz, 5GHz) in the FortiAP profile and reapply or reboot the AP”.

FortiAP Profile Settings:

Go to WiFi & Switch Controller > FortiAP Profiles.

Edit the FAP23JF profile.

Check both “Radio 1” and “Radio 2” (enable if disabled).

Save the changes and ensure the profile is pushed to the AP.

Typical Steps to Fix:

Log into the FortiGate.

Navigate to WiFi & Switch Controller > FortiAP Profiles.

Edit the FAP23JF profile.

Under the radio settings, ensure both radios are set to “Enable”.

Apply the changes.

The AP will now broadcast the SSIDs as configured.

Summary:

The problem is caused by disabled radios in the FAP23JF FortiAP profile. Enabling the radios in the profile will allow the AP to start broadcasting SSIDs.

Final Answer: A. Enable the radios on the FAP23JF FortiAP profile.

Scenario:

The IT department wants to prevent direct communication between wireless stations.

There is one SSID configured in bridge mode (all clients on the same SSID/VLAN, directly bridging to the wired network).

Correct Action:

Block intra-SSID traffic (sometimes called “client isolation” or “intra-SSID privacy”).

This feature prevents wireless clients connected to the same SSID from communicating directly with each other at Layer 2.

Each station can reach the network but cannot reach other wireless clients on the same SSID.

This is the industry-standard method to achieve the stated security goal in a wireless environment, especially in bridge mode.

Why Other Options Are Incorrect:

A. Create unique SSIDs for each FortiAP device

Impractical and unnecessary for user isolation; users on the same SSID but different APs can still be isolated with intra-SSID blocking.

B. Add an upstream layer 3 device on each FortiAP device

Overkill and not required; this does not directly solve intra-SSID traffic.

D. Drop all local traffic in the wireless network

Too broad; you only want to prevent client-to-client communication, not all local traffic (such as traffic to the gateway).

Summary:

Block intra-SSID traffic is the intended and correct configuration to prevent wireless stations from communicating directly while sharing the same SSID in bridge mode.

The scenario involves employees connecting via remote FortiAP (FAP) devices, with a requirement to enforce corporate security policies for all wireless stations at branch/remote sites.

Teleworker topology (also called remote AP, or split-tunnel mode) is designed exactly for this:

FortiAP at remote sites connects to the main office FortiGate via a secure tunnel (CAPWAP over VPN or DTLS).

Traffic destined for corporate resources is tunneled back to the main office for full security inspection and policy enforcement.

Local internet-bound traffic can be split off locally (split-tunnel) or tunneled back as well (full-tunnel), based on policy.

This ensures all employee wireless sessions accessing corporate resources are subject to central security policies, without requiring local IT staff.

Option A (VPN tunnels) is part of the teleworker topology but doesn't by itself ensure wireless security enforcement or policy application for wireless stations—teleworker/split-tunnel is more precise.

Option B is impractical and unnecessary.

Option C moves resources to the cloud, but this does not ensure security enforcement for wireless clients over remote links.

Summary: Teleworker topology on FortiAP allows secure, policy-enforced connectivity from remote sites back to HQ for all wireless stations.

802.1X is the standard for port-based network access control, widely used in enterprise Wi-Fi to:

Authenticate users and devices before granting access to the network.

Authorize network access (optionally placing users into specific VLANs).

It is not for home Wi-Fi (C), does not provide admin privilege (B), and is more complex than open guest Wi-Fi (D).
