I am using a wireless LAN by connecting FortiAP421 and FortiAP431 to Fortigate60E.

Occasionally, there are instances where client devices get disconnected.

The logs output during those times are as follows:

- Wireless client left WTP

- Action client-leave-wtp

- Reason Unspecified reason.

Does anyone know the cause of this log? If I were to investigate, how should I proceed?

Hi,

The Reason Unspecified reason could be Mutiple reason, and some time can be due to coverage issue.

Kindly check the power settings for the AP, at the time of the reported failure could you validate if the client tried to connect to another closer FAP?

The client is connected to 2.4GHz or 5GHz, if is 2.4GHz could be due to interference issue, kindly check the channel are configured properly.

You can check for sticky client issue and fix as per the below document.

Disable AX on both radio if you are not using the 802.11ax support client.
