Problems with Mikrotik base station 5 ghz

We have problems with mikrotik base station(Wireless multipoint equipment 5 Ghz) where the sectors talking to each other, resulting in connecting/ disconnecting many times in few minutes. B4:47 is the MAC adress to base station and not any client. Thee result is loop in the entire net. We are using the same ESSID on each sector on the base station. This is a critical problem for us, can anyone help us or have seen this problem.

Client loop
jul/07/2005 13:56:55 wlan3: lost node, excessive data retries,
00:02:6F:22:2E:B7
jul/07/2005 13:56:55 wlan3: 00:02:6F:22:2E:B7 disconnected
jul/07/2005 14:00:52 wlan4: lost node, excessive data retries,
00:02:6F:22:2C:22
jul/07/2005 14:00:52 wlan4: 00:02:6F:22:2C:22 disconnected

why not just reject the B4:47 MAC from the registration list of the other sector.

Are you using WDS on these APs as well?

Thanks, we are using WDS on these AP

disable authenticate on interface properties.

lost node, excessive data retries

I oftenly got this message, but change the frequency solved the problem :smiley: (maybe interference with another AP)
