Link dropped, won't reconnect

I can’t get the slave B24 to reconnect after connection was dropped for some unknown reason.
Everything was working perfect for several days, but suddenly link dropped.

Fortunately I have backup link running.

What to do ?

I have access to both ends (because of backup link). Everything seems correct ? Any suggestions ?

Try changing the AP to a station and the station to an AP and see if they will reconnect.

I assume you have changed frequencies, maybe some sort of unseen interference? How long is the link?

I think that is the problem of the firmware I have b5lite and it happens to me continuously that problem is restarted and after 4 or 5 days it turns off, when restarting the antenna it does not connect after several times turning off, turning on the slave again

creo que ese es el problema de del firmaware tengo b5lite y me pasa continuo ese problema se se reinicia y tras 4 o 5 dias se apaga , al volver a reiniciar la antena no se conecta tras varios veces apagando , encendiendo vuelve a conectar el esclavo
