Access Points Diagnostics and Tools
The Diagnostics and Tools pane displays the details about the selected Access Point/Radio and allows you to run diagnostic tests.
Performance
The performance tab displays the performance data for selected interval. It includes charts for Clients, Bandwidth and Channel Utilization. The default interval is 1 hour and can it be changed according to your requirements.
Clients
The Clients tab displays a list of clients currently connected to the selected AP, along with details such as the MAC address, FortiGate, IP Address, FortiAP, SSID, Device, User, Channel and other information. This information is useful for identifying any clients that may be experiencing connectivity issues or data usage problems.
To view detailed information of a client, select the client and click View details.
Interfering SSIDs
The Interfering SSIDs tab displays the details of interfering SSIDs associated with an AP; the interfering SSID page displays the SSID name, related AP BSSID, channel, signal strength and the Radio ID are displayed in the AP dashboard. To view the interfering SSID details, ensure that the AP radio is using Radio Resource Provisioning or a WIDS profile in FortiGate (Managed FortiAP Profile).
Logs
The Logs tab provides detailed logs of events related to the selected AP/Radio. To view detailed information, select log and click Details. Click Download to download all the logs in .csv format.
Spectrum Analysis
Spectrum Analysis tab provides visual spectrum analysis capabilities that scan radios for RF channel conditions and sources of interference which can potentially impact WLAN efficiency. Based on the spectrum analysis data, corrective measures such as determining optimal channel planning, debugging client related connectivity issues and automatic transmit power settings are initiated. This facilitates quality wireless service levels by ensuring the optimal usage of the channels considering the information provided by the FortiAIOps spectrum analyser. Both 802.11 and non-802.11 sources of interference can be detected and analyzed by the spectrum analyzer.
Notes:
-
Spectrum analysis is not available for G Series FortiAPs.
- Spectrum analysis is only supported when the radio is in the monitor mode.
- FortiAP supports spectrum analysis and is online.
Select the channels to be scanned and configure the scan duration, the spectrum analysis is performed on both 2.4 GHz and 5 GHz frequency bands. The spectrum analyzer result displays widgets with the type of interference, signal strength, impacted channels, and wireless spectrum current utilization, start and end time and duration of the interference. It classifies wireless & non-wireless interferences to easy identification of the source.
- You can select the AP, Radio, and Channels to be scanned for interferences.
- The Scan Duration can be set to 1, 5, 30, or 60 minutes.
- The Sampling Interval and the number of Spectrogram Samples cannot be modified.
Select Start and the GUI periodically polls the spectrum analysis data based on the fixed sampling interval of 1000 milliseconds. Data is visualized as 4 charts representing signal interference marking the noise levels for each channel, signal interference spectrogram representing 60 samples for different channels at specific time intervals, the duty cycle charts marking the extent to which a non-WiFi device/neighbouring AP is interfering, and the duty cycle spectrogram representing 60 such duty samples for each channel over a period of time.
The tabular data for non-WiFi interference displays the time and frequency of last detection and any of the following type of devices causing the interference.
- Microwave ovens
- Video bridges
- Wi-Fi, DSSS cordless phones
- Bluetooth, FHSS cordless phones
The tabular data for WiFi interference displays the online neighbouring AP's BSSID, SSID, maximum signal strength, and channel and time of last detection.
VLAN Probe
VLAN probe tab enables FortiAPs to probe connected VLANs and subnets. It sends DHCP probes from the FortiAP’s Ethernet interface to specific VLANs on the wired interface and returns information on their availability and subnet details. This helps diagnose and troubleshoot WiFi deployment issues.
- Probe Retries – Configure the number of retries before timeout. The valid range is 1 to 10 with a default value of 6.
- Timeout – Configure the timeout for the VLAN probe. The valid range is 1 – 60 seconds with a default value of 10 seconds.
- VLAN Range – Select the range of VLANs to probe. The valid range is 1 - 4094.
Select Start to initiate VLAN probe as per configurations.
