Hi.
I have a 47km link with a RB411ah and RB433. I get “wlan1: data from unknown device xx:xx:xx:xx:xx:xx, sent deauth”. The device is my other wireless device. I checked it now and it was running for 1d 16h. Some times this happens few times a day, about every 2 to 3 hours, then it runs for few days without disconnecting. If you reboot one of the devices it takes anything from 5 - 15 minutes to reconnect. I have attached screen shots of the log and signal.
Any help and advice will be greatly apreciated.
