Disable all firewalls, as Norton, Zone alarm etc.
Also disable windows firewall from control panel.
If it still does not work check the router settings. Routers have internal firewall, you may need to add your laptop's ip or mac address to the firewall as trusted one.
An alternative is connecting laptop by wires to the router, probably the router firewall will let it go , as wired connections are set to less resticted security.
