Hmm.. This means there had to be a peer kickout event generated in
firmware and your hostapd is configured to handle low-ack events as
Ben recently raised a problem concerning ACK problems . Perhaps
that's one of the manifestations.
You could just try disabling the `disassoc_low_ack` option in hostapd.
Stations will still be disassociated when they go out of range and
don't respond to NullFunc frames pings after a few minutes of idling
(from AP point of view).

Can you point to the ath9k thread/patches, please?
