And my wireless connection is perfect. Good Lord, that's a really bad situation!

With a "C" rank, your ability to display all available rooms is blocked, and only 1 room will show up at time. You have to play, and successfully finish, several missions until your rank raises to "B". I don't know if you can still be invited by your friends: I would try if possible, mainly because the only room you will find each time is usually what you would never play normally.

As for your connection, I would check if the PS3 works fine: do these errors appear only with Infinity? Or is there at least one more game which gives you troubles? TCP/UDP ports should be checked too, just like the router firewall (if you have one).
