Another long shot, but I noticed your network screenshot differs slightly from mine (I have an Internet Connection status line at the very top which you do not). Can you look up what version of PS3 System Software you are running? It's in System Settings->Syetem Info. You should be at "Version 2.76"
Ahah! It works! I restarted my router, switch, and computer and for some reason it works now. Just one of those stupid things....Thank you SO much for your continued help. Can't wait to enjoy this product!
