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
