hostapd and atheros - anyone else with dropping connections ?!

I have a wifi atheros card:

ath0_at_pci0:10:0: class=0x020000 card=0x3a131186 chip=0x0013168c rev=0x01 hdr=0x00
    vendor     = 'Atheros Communications Inc.'
    device     = 'AR5212, AR5213 802.11a/b/g Wireless Adapter'
    class      = network
    subclass   = ethernet

and an hostapd AP.

from time to time, I need to restart hostapd. and this time is not long.

I'll update now and try again.

if anyone is having the same issue, please say :)

thanks,

matheus
