>>You say you've setup the router via the PC. Did that include setting up the required security (WPA/PSK) and changing the SSID? If so have you setup the wireless security on the laptop? Do you have a firewall on the laptop and have you allowed access through it for the router?

I haven't changed the SSID - it says RG60SE (the make of the router). I haven't got a clue I haven't done anything to the laptop apart from restore factory settings and give up.

How do I allow the router access through the firewall?

Thank you for your help!
