Then I note that I have a different problem ;-)) Do you suggest the problem could come from an improper handling of the association dropout at the client (the DLink DW-900AP+)? I do not know what happens at the protocol level when the connection gets broken but I can see that sometimes the client recovers the association and some other times the connection simply drops. Is there any configuration of the wireless interface that can help in keeping the association alive?
