Hi Archana,
Welcome.

* Nice to hear that your setup works fine.

* wpa_supplicant means,it is software for Wireless STA's.Since you wanted to bring your X86 machine as AP,you no need to worry about wpa_supplicant.

* [ARCHANA SAYS]Ping test fails.
  [AMBEDKAR SAYS] The reason for ping failure,there may be only wireless interface up and running(RADIO),to reach ethernet we need brige interface,which you may not be configured in your X86 machine.Bridge interface acts as converting 802.11[Wireless LAN] packets into 802.3[LAN or whichever network it goes] packets or vice versa[You might be aware of PORTAL.A PORTAL peforms the INTEGRATION service is nothing but act as bridge between two different techniques]

Use the following command to bring up the setup.

#wlanconfig atho(or eth1) destroy
#wlanconfig atho create wlandev wifi0 wlanmode ap
# modprobe or insmod
--------------------If AP already running,dont use the above command,

Use the following command to bring up the BRIDGE Interface
#iwconfig ath0 down
#iwconfig eth0 down
#brctl show ------------------to check bridge intefce created or not.
#brctl addbr br0
#brctl addif br0 eth0
#brctl addif br0 eth0
#ifconfig ath0 up
#ifconfig eth0 up
#ifconfig br0 192.168.1.1

Use the above command carefully.

#hostapd -dd hostapd.conf
Hostapd takes the configuration from hostapd.conf and runs.

Try it out and update me ,will bring the setup today itself.

Thanks
