Hi Adrian, I've been away for the weekend and just got back home planning to try = this out but the problem seems to have cleared itself up whilst I was = out. I'm not sure how, or if it is likely to come back. I have just = powered on the FreeBSD box after a few days switched off - but I had = earlier rebooted it several times which didn't clear the problem so I'm = not sure its that. I have tested from multiple clients. I guess all I can do now is wait and see if the problem reoccurs and if = so try and determine the triggering factor. Maybe a specific client = being associated? I don't see anywhere near the number of power save = on/off messages that I was before. Thanks for your help. I'll repost if I get a reproduction. If there is = anything you would like me to try anyway to aid debugging I'm happy to = do it. Thanks again, Andrew=
