Hi, I'm new in this forum and I don´t speak English very well, I hope you can understand me.
I have a PtP link with two Mikrotik LHG 5 with 6.43.8 firmware but randomly the client is disconnected from AP. This is the log:

@wlan1: disconnected, received deauth: authentication not valid (2)
02:21:03 wireless,debug wlan1: CC:2D:E0:1E:F4:EB attempts to associate
02:21:03 wireless,debug wlan1: CC:2D:E0:1E:F4:EB not in local ACL, by default accept

After that, the client is connected again but this occurs frecuently.

Thanks for your help.
