Unable to connect wireless network to Blu...

I have a Samsung BD P-3600 Blu-Ray player and a D-Link DIR-655 wireless router. When I select my wireless network and input the password, the screen on the TV says ''connected,'' but then when I try the network connection test, it fails and says ''your network cannot operate properly.'' I typically pass the first three steps on the network connection test, which are ''MAC Address'', ''IP Address, Subnet Mask, Gateway, DNS Server'' and ''Gateway Ping,'' only to fail on the fourth and final step, which is ''Internet Service Test.'' Samsung told me to unblock ports 80 and 443 on the router, which I did without any change in results. D-Link told me to try using WEP as the security setting, rather than WPA, but that didn't help either. I've been rebooting the equipment and trying every possible combination I can think of. So far, no luck. Has anyone else encountered the problem with connecting this player? Does anyone have the solution or advice on what else to try?
