  range 192.168.200.2 192.168.200.20;
  option subnet-mask 255.255.255.0;
  option broadcast-address 192.168.200.255;
}

/etc/hostapd/hostapd.conf
interface=wlan0
driver=nl80211

hw_mode=g
channel=11
macaddr_acl=0
ignore_broadcast_ssid=0
auth_algs=1
wpa=2
wpa_passphrase=Passw0rd!
wpa_key_mgmt=WPA-PSK
