I am trying to connect my son's PS3 to my wireless network. Every other computer in my house is connected to my router and we have no problems connecting our PCs. However, we enter my WPA key and wait and then receive the error message "The attempt to obtain an IP address timed out". Can someone please help me figure out what the problem is? I've done everything the manual said to do - unplugged my modem, router and turned off and on the system. I can't figure it out and appreciate any help anyone can send my way. Thank you!
