Activision today posted several tutorials in regards to removing lag from the online multiplayer portion of their recently-released Playstation 3 and Xbox 360 title, “Black Ops 2.” The publisher first suggested a general solution of switching a Wi-Fi connection to a wired Ethernet hookup. If lagging still occurs, Activision also posted several console-specific solutions.

  1. Disable any firewall or security features on your router.
  2. Set port forwarding on your router to the IP address of your PlayStation 3. This game uses ports 36081, 3074, 3075, 3478 UDP (User Datagram Protocol) and ports 80, 81,443, 3074, 5223 TCP (Transmission Control Protocol.)
  3. Disconnect your router and try the game. If it works regularly at this point something about your router may not be completely compatible with the specific needs of this game. Check with your router manufacturer and Sony’s PlayStation 3 Connection Issues page for additional steps that may need to be done to resolve the issue you are having.
  4. Place your PlayStation 3 into the DMZ of your router.

If you are having issues connecting while multiple PlayStation 3 consoles are connected on the same network, try forwarding the ports 36081, 3074, 3075, 3478 UDP 80, 81,443, 3074, 5223 TCP for one PlayStation 3 and setting the other as DMZ. There is a chance that this may not resolve your issue, if it doesn’t then you may want to consider getting an additional public IP address by contacting your Internet Service Provider and assigning it to one of the consoles.

NOTE: If setting port forwarding or DMZ helps your connection issue, you may want to assign your PlayStation 3 a static IP address within your home network. This can help to ensure that the configurations you made do not need to be done again. You can visit PortForward's Static IP Guide for a detailed guide on how to do this.

NOTE: Many broadband internet modems are coming with routing capabilities built in. Please contact your internet service provider to determine if your internet modem has an integrated router. If it does, they should be able to assist you with the steps above for setting up your router.

Once you have verified that your network setup is not the cause of the issue, try connecting to a different server. Some servers may have other players connected to them that you do not have an optimal connection with. In most games this is accomplished by backing out to the main menu and then selecting multiplayer again. From there you can try connecting to another online game.

Moderate and Strict NAT types may have issues connecting to online matches. You may get the error "Notice - The game session is no longer available."

Please consult your router documentation for instructions on how to do this
