Step 1: Check the Xbox Live and Call of Duty Status Pages
Check the Xbox Live Service Status page, as well as the Server Status of the Call of Duty game you are playing:

Call of Duty: Advanced Warfare
Call of Duty: Ghosts
Call of Duty: Black Ops II

Step 2: Improve your Home Network Quality
The quality of a home network will have the biggest impact on game connection. We suggest the following steps. Note that you can test your Xbox Live connection at any time.
  1. Be sure to restart your router. This will often solve the issue.
  2. Make sure you are playing the game using a wired Ethernet connection. Playing a game using a wireless connection is the primary cause of lag and connectivity issues. Wi-Fi has a wide variance in reliability and bandwidth, and can dramatically affect the quality of online gameplay. A wired connection will maintain the minimum bandwidth connection that is required for online gaming.
  3. Disable any firewall or security features on your router. See your router’s instruction manual or visit the router manufacturer’s website for more details.

  4. Enable Universal Plug and Play (UPnP) on your router. This will automatically route the correct data to the correct ports.
  5. Set port forwarding on your router to the IP address of your Xbox using port 3074 User Datagram Protocol (UDP). If there are multiple consoles on your home network, you can also redirect UDP ports 3074, 3075, and 3076 to the console (one port per console). How to forward ports.
  6. Place the IP address of your Xbox into the DMZ of your router.
If the above steps improve your network connection to the game, you may want to assign a static IP address to your Xbox 360 within your home network. This will ensure that the configurations you made do not need to be repeated. Please note that Satellite, hot spot, and 3G/4G internet connections are not considered broadband and are not supported.

Step 3: Change your Playlist Search Preferences
  1. Select Search Preferences from the Playlists menu.
  2. Change the Connection Type from Best or Any to the recommended Normal setting.
