Which kernel version are you using? Is ath9k from the same kernel or

Which client device are you using? Have changed the station inactivity
timeout (ap_max_inactivity in hostapd.conf)? By default, it is five

I would suggest running hostapd with verbose debugging (-ddt on command
line) and see whether something shows up at the point when the data
connection fails. hostapd should ping the station if it is inactive for
longer than ap_max_inactivity and assuming a response is received,
connection should be allowed to continue; if not, the station will be
disassociated. Either way, the station should be able to continue using
the connection (after reassociating in the latter case).
