I have tied to set up a wireless netwoek but have not been successful. The router is a D-Link DI-713P and I am trying to connect it to a cable network provided by comcast. I have set it up as described in the manual ,ethernet card on the desktop to the router and the cable modem to the WAN connection of the routerl. I can successfully ping the router from the desktop but it will not connect to the iternet. All of the lights on the router are doing what the manual says they should during and after start up. The laptop cannot successfully ping the router but the card does seem to find a connection. When I plug the desktop back into the cable modem it successfully connects to the internet. I have also tried to enter the router configuration tools as described in the manual by entering the IP address into the browser but that also fails. Any suggestion on what I am doing wrong?
