I have several Routerboards that use WDS to connect to each other via (bridged) AP-AP links. Occasionally, I am seeing outages in which Routerboard A thinks the WDS connection is fine (though showing Rx=0), while Routerboard B shows no WDS connection and the log indicates "unicast key exchange timeout". Toggling the radio on Routerboard A usually gets the connection working again.
It sounds like this might be related to a long-standing WDS/WPA2 incompatibiliity. Apart from a forum search (which I have already done), does anyone have any insight into this problem? Is it a basic protocol or hardware incompatibility, or is this simply a bug in ROS that our good friends in Latvia could fix once it reaches the top of their priority queue?
[I will submit supouts from two of the devices, generated during one of these outages, later this evening.]
