Problem getting my PS3 online
 

As of two days ago I had no issues getting my PS3 online via wireless router. Now it won't connect and no matter what I do I get the network to find the IP address. Even when I manually enter in the IP address, I then get a message saying "cannot establish connection to the internet". I know my wireless is working fine because my laptop finds it... any advice?

I've reset my system and tried to re-establish the connection a dozen times, it's always the same IP address time-out failure.
