the SSID is VERY important..lol it's the name of your wireless conenction, and is case seitive

just get the ps3 to search and find your wireless conenction, then enter the key, thats it

if your router is not broadcasting, then enter the SSID EXACTLY as it's written on the box

then enter the key

forget proxy, and IP will be automatic, unless you have accidentla clicked manual, if so, put it back to automatic (dhcp)
