Hi everyone. Got my wireless router today and eveything was going well. My playstation picked it up and is showing 83%-100% signal strength. I went to sign up for Playstation Network and thats where my troubles started...at the end of the sign up process it said Playstation Network has timed out

and to check network connection. But the internet etc works fine so why does this not? Help much appreciated as I am itching to play online.
Thanks?
