Finally I was able to find out the case which makes my wifi to stop working.
The problem is easily reproducible if second laptop is associated with AP.

My AP configuration (PC with FreeBSD 7.2) is listed below:

interface=ral0
debug=2
ctrl_interface=/var/run/hostapd
ctrl_interface_group=wheel
ssid=freebsdap
wpa=1
wpa_passphrase=*************
wpa_key_mgmt=WPA-PSK
wpa_group_rekey=1800
wpa_pairwise=CCMP TKIP

local wpa_supplicant.conf is like below:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
fast_reauth=0
eapol_version=2
network={
    ssid="freebsdap"
    key_mgmt=WPA-PSK
    auth_alg=OPEN
    psk="*************"
    scan_ssid=1
}

My primary laptop is ASUS K40IN with wifi card on AR9285 chipset, another
laptop is ASUS K40IJ with wifi card on AR9285 chipset too.

And once second laptop gets associated with AP - my one stops to recognize
wifi connection. But it's still listed as associated in ifconfig output. And 

wpa_cli reassociate

doesn't solve the problem - I have to restart wpa_supplicant.

Does this make any sense? Should I submit PR or there is some
misconfiguration?
