Same problem here, I turned ps3 off via plug socket, reset router gave it a min or two now it's working. Good luck hope it's fixed!!

After restarting my PS3 3 times, and pressing : PLAY ONLINE multiple times, it finaly worked, but if i'm going to search for a match, it can't find any i think IW must do something about all the fetching online profile errors

I'm about 7 months when i press Play button in Mw3 mp & sp , Fetching online profile displayed to me and after that i get server connection error.i tried a lot of difrent ways to solve the problem but i couldn't.For example i change my Isp, i used to start proxies , i changed server in steam from a country to other countries , i delete my game and download it again with steam , i reinstall my windows 3 times & ...

but non of them solve my problem...

and i know i don't use any cheats so i'm not bann!

so what should i do?!
