 unzip hostapd.zip
 sudo mv /usr/sbin/hostapd /usr/sbin/hostapd.bak
 sudo mv hostapd /usr/sbin/hostapd.edimax
 sudo ln -sf /usr/sbin/hostapd.edimax /usr/sbin/hostapd
 sudo chown root.root /usr/sbin/hostapd

 3. Edit
 sudo nano /etc/hostapd/hostapd.conf

 interface=wlan0
 driver=rtl871xdrv

 ifconfig wlan0 192.168.0.1 netmask 255.255.255.0

 or on system startup in

 sudo nano /etc/network/interfaces
 allow-hotplug wlan0
 auto wlan0

         broadcast 192.168.0.255

 6. restart stuff
 sudo /etc/init.d/dnsmasq restart
 sudo hostapd -d /etc/hostapd/hostapd.conf
 or
