Below (headed "AP") is part of a a console log from an RB532. It's a AP on a point-to-point link to the card on another 532 referred to in the log. Also (headed "Station") is the corresponding part of the log from the Station.

This has been happening for several months. Can anyone suggest what might be going on?

Ok guys, it's still happening on a regular basis two or three times a day just for a couple of minutes each time.

The station reports "lost connection no beacons" and then "failed to connect, join timeout" for a couple of minutes before re-establishing contact. The AP reports "disconnected, reassociating" and then "connected" at the end of the same period but has nothing for the moment the station reports loss of beacons.

Anyone any ideas?

OK, here's the debug log from the station for an incident last night.

I tried to get the equivalent entry from the AP. The Winbox > log merely reports a client disconnect and reconnect for this time on this interface only.

So I'm none the wiser.

OK, here's the debug log from the station for an incident last night.

I tried to get the equivalent entry from the AP. The Winbox > log merely reports a client disconnect and reconnect for this time on this interface only.

So I'm none the wiser.
