Yeah the use-case is important. And for mine where connectivity/uptime is very critical even a 1 second comeback delay is too long and I would want the device to roam/connect elsewhere, which then leads back to CMD_ASSOC_COMEBACK. So no matter what I'll need that event, I was mainly trying to figure out why the kernel let these excessive wait times happen. I don't have an answer as to where the cutoff would be though, so I guess I'll drop it for now. Thanks, James > > johannes
