The attempt to obtain the IP address timed out...

Has anyone had this issue before?

I changed my wireless from WPA-PSK to WEP, but now I've changed it back and my ps3 can't get online. What gives?

Setup a new connection.

its ur ps3, not ur ip address, mine does the exact same thing, its retarted when it comes to getting online, some times for no reason at all it just refuses to establish a connection, obvious design flall..
