Description
This article describes how to avoid logging out users from the Wi-Fi connection, showing 'wrong password'
Some users present disconnection or logoff from the Wi-Fi interface with the message 'wrong password’, even if the credentials have not been modified.
Scope
FortiAP.
Solution
Modify in the SSID configuration the value for 'gtk-rekey-intv' in 'wireless-controller vap'.
This value is the GTK rekey interval of WPA security.
WPA automatically changes secret keys after a certain period of time.
The group rekey interval is the period of time between automatic changes of the group key, which all devices on the network share.
WPA changes the group key.
Modify this value from the default (3600) to 864000 (maximum value), using the following command:
config wireless-controller vap
edit name_SSID
set gtk-rekey enable
set gtk-rekey-intv 864000
next
end
