I think you need to check the Network connections, make sure that you have proper Wireless Network Connection Icon and also properties of the icon. First make right click on the wireless network icon and after that select the properties. Make sure that you have configured the TCP/IPv4 protocol on the Network Connections Properties. go through this all and after that let me know the issue.
