Hello there, I have recently bought a Sony Vaio laptop which is installed with Windows 7. I used to connect the laptop to the Dlink Wireless router for accessing Internet on the laptop but the now the laptop is not able to connect to the router. Everytime I try to connect the laptop to the router, it gives an error message saying "There is no connection on ipv4 and ipv6". Also the laptop shows limited connectivity. How do I solve Ipv4 & Ipv6 no connection problem? Please help.
