I have a D-Link wireless router which is servicing 2 laptops. I have trouble connecting to certain secure sites from the laptops but can do so fine with my main computer hard wired to the main router. I suspect the wireless router's default filtering/firewall is the culprit. How do I unset those so that I can access the secured websites (e.g. Citi Masterard login site) from the laptop?

D-link released many routers, what is you'r exact model ?
