The Dlink wireless modem is configured correctly and the computer/laptop can access the Internet wirelessly.
The PS3 needs to be configured with the Dlink modem's wireless settings so it can communicate with the wireless modem.
To configure the PS3 please follow these steps :-
1. Power up the PS3 and login then Select Network Settings and
press X

If there is no encryption I suggest you enable the encryption on the wireless modem, use passphrase to generate the encryption key.
Write down this encryption key, you will need this key for your
computers and PS3.
8. Enter the WEP or WPA encryption key (from the wireless modem) then press > button
