Hey guys. I'm sorry for the dumb question, and I DID search, but I'm still kind of new to some of this stuff. What is wi-fi? I already have a router, does this mean that the PS3 can connect without having to plug an ethernet cable or device in? With the Elite, I have a wireless network adapter plugged in to get online. I had been using this same netword adaptor on the PS3 untill I started reading about wi-fi. Thanks for any help.
