After Long hours research On netgear routers, i have came to the solution that any DHCP network need 5-10 minutes to be fully functional. As i connected my negear router to my Modem i restarted every thing i.e My desktop,My internet modem Provied by TATA INTERNET SERVICES LTD. and my Netgear WGR14 v9 router. In the router a pressed reset button for couple of seconds to restore its factory settings to default. Now everything was coooool..!!! I started configuring my netgear router after connecting particular cables to their respective ports...(I hope no need of explanation) The I logged in to my netgear settings wizard with the address hxxp://192.168.1.1
On the basic settings tab I got tested my network connection and applied the settings for LAN. Smiles at heights

Now coming at wireless I was able to setup a secure a secure wirless network and the test on my vaio was sucess..
