We have a customer that experiencing random 2600/3600 access points disconnecting from an 8510 WLC running 18.104.22.168 code. The ap's which are disconnecting appear to be completely random. So far we have lost all ap's at one site, 3 at another and 1 at another. These drops happened on different days at differnt locations (both wan and lan).
They appear to be in standalone mode and still serving clients when this happens. The only way to get them to join the controller again is bounce the poe port. I think we'll need to open a TAC case but wanted to run this by the community here to see if anyone has experienced something similiar or has any suggestions.
There are a few bugs with v7.4 and 3602's which you most likely are hitting. You are better off opening up a TAC case so they can tell you if its a bug which might be existing or new. They can also provide a TAC release that may fix the issue.
