hostapd connection breaks

Hello there.

Today I noticed some wired behavior from my asus phone, every couple minutes there is no connection with FreeBSD as host based AP.

Code: 
interface=wlan0
debug=2
ctrl_interface=/var/run/hostapd
ctrl_interface_group=wheel
ssid=someSSIDap
wpa=1
wpa_passphrase=PASSWORD
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP TKIP
Code: 
% cat /usr/local/etc/dhcpd.conf
# dhcpd.conf
#
# Sample configuration file for ISC dhcpd
#


ddns-update-style none;
authoritative;
#log-facility local7;

subnet 192.168.40.0 netmask 255.255.255.252 {

  option domain-name-servers 109.194.160.1, 109.194.161.1;
  default-lease-time 600;
  max-lease-time 7200;
}
Code: 
%cat /etc/rc.conf

After deleting leases:
Code: 
sudo rm /var/db/dhcpd/dhcpd.leases*
sudo service isc-dhcpd restart

Code: 
% tail -F /var/db/dhcpd/dhcpd.leases
# The format of this file is documented in the dhcpd.leases(5) manual page.
# This lease file was written by isc-dhcp-4.3.2

  set vendor-class-identifier = "dhcpcd-5.5.6";

}

Code: 
%tail -F /var/log/messages

Questions:
  1. What's wrong with, because there was internet on my phone for a months, and now there is a problem, but I didn't change anything, even no port upgrades?
  2. Why net/isc-dhcpd tries to apply same ip to one device couple times?
  3. How to debug more deep, /var/log/messages shows at least nothing?

P.S. I have another device (ipod) which act the same way - breaks connection sometimes.
P.S.2 If i will ping to device, there would be tunnel, as long as ping goes.
