The terminal frequently goes offline because of Reason: AP triggered (kick station by fast keep alive) . What does it mean?

 The direct cause is that the fast keepalive function of the device detects that the terminal is idle and kicks the terminal to go offline. This function is enabled by default. In theory, the terminal is no longer within the communication range at this time, and it has no effect on normal use. If you really feel that this detection has an impact on the terminal, you can disable this function by undo rrop client fast-keep-alive in radio view
