A friend of mine has got a problem with his internet. Everytime he plays Call of Duty: Black Ops online, he gets the message: "Disconnected from server". But not one time, no, every freaking minute. With this, it's not fun to play online. He forwarded all of his ports (NAT Type is open), but he still got the message every single time. He uses wired internet. I thought maybe you guys know what the problem is.
