Why is not my Internet work for PSP?

The signal strength is 100% I have the SSID BSSID Channel 6, I am safety (WPA-PSK [AES]) I got the IP address subnet mask, I do NOT have the default router thing. I have no idea how to recover. I have the Primary and secondary DNS. I have the MAC address. I'm not using proxy server. Internet connection failure What am I doing wrong????

could be the firewall settings If you have a firewall turn it off or disable your WPA-PSK

I have a psp connection problem
