Data from unknown hot, sent deauth spam

My log is full of this:

It seems the device spamming does not understand deauth or something? I am using Access list and this device is not allowed. If it is a phone i guess the battery on it is draining fast… Any way to stop this behavior?

Using RB493G, 3xR52H running 6.13

I tink is one cracker than one errors…
Try to change SSID…
