hello, thanks in advance if I can explain what happens here, the system takes several days like that. (I speak Spanish and this is a translation of google)

It means “other end forced disconnection with no speficied reason”. What is that MAC address in the log, is that device also controlled by you?
is not controlled by me, I do not know who is this season.
but when I click “scan …” To see other stations (AP) I see that this is another access point neighbor, who is unaware of
if you want, you can block this MAC.
[admin@r] > interface wireless access-list add mac-address=FF:FF:FF:FF:FF authentication=no
or you can hide your SSID so that nobody else sees it, just your stations. you will have to tell the SSID to all stations though.
