Monitoring wireless clients

You can view detailed information about the health of individual WiFi connections from WiFi and Switch Controller > WiFi Clients. You can also Quarantine or Disassociate a wireless client from there.

To view connected clients on a FortiGate or FortiWiFi unit

1. Go to WiFi and Switch Controller > WiFi Clients.
   The following information is displayed by default on both the FortiGate and FortiWiFi units:

   Column headers	Description
   Association Time	How long the client has been connected to this access point.
   Bandwidth Tx/Rx	Client received and transmitted bandwidth, in Kbps.
   Channel	WiFi radio channel in use.
   Device	The name of the device.
   FortiAP	The serial number of the FortiAP unit to which the client connected.
   IP	The IP address assigned to the wireless client.
   MAC Address	The MAC address of the device. Note: This column is available on the FortiGate only.
   Signal Strength	The current signal strength and health.
   Signal Strength / Noise	The signal-to-noise ratio in decibels calculated from signal strength and noise level.
   SSID	The SSID that the client is connected to.
   User	The user name associated with the device.

   You can hover over the columns and click the Settings icon to add more columns to the table:

   • Authentication
   • Band
   • Bandwidth RX
   • Bandwidth Tx
   • Device OS
   • Encryption
   • FortiAP IP
   • FortiAP Radio
   • Group
   • Host Information
   • Idle Time
   • IPv6 Global Unicast Address
   • IPv6 Unique Local Address
   • Manufacturer
   • MIMO
   • Noise
   • Pre-shared Key
   • Rate Rx
   • Rate Tx
   • Security FabricVLAN ID

You can also click each row and drill down for a summary about the applications, destinations, policies, and logs on each client. From the summary page, you can also choose to Quarantine or Disassociate the host.

To quarantine the host

You can block a specific host for your network by quarantining it.

1. From the WiFi Clients page, double-click the client you want to quarantine.

   The client summary page loads.

2. Click Quarantine to open the Quarantine Host dialog.
3. Click OK to quarantine the selected wireless client, and close the dialog.

To disassociate a host

You can remove a specific host from your network by disassociating it.

1. From the WiFi Clients page, double-click the client you want to disassociate.

   The client summary page loads.

2. Click Disassociate.

   The Confirm dialog opens.

3. Click OK to disassociate the selected wireless client, and close the dialog.

Understanding client health

From the summary page, the Health section displays the overall health for the wireless connection. The overall health of the connection is:

• Good if the value range for all three conditions are Good
• Fair or Poor if one of the three conditions is Fair or Poor.

Condition	Value Range
Signal Strength	Good > -56dBm -56dBm > Fair > -75dBm Poor < -75dBm
Signal Strength/Noise	Good > 39dBm 20dBm < Fair < 39dBm Poor < 20dBm
Band	Good = 5G band Fair = 2.4G band
