Try going to start then run, type cmd then type ipconfig /release then ipconfig /renew then ipconfig /flushdns
Also, go to start run services.msc make sure the wireless services are started and the DHCP and network services are started.
If that doesn't work, it could be a problem with your firewall and or router.
Hope this helps
