If you’re having trouble connecting to a Call of Duty game, you should first check the status of online services.

If the status indicator for your platform is not green or an alert is present, you might encounter connectivity issues until service is restored and fully operational.

However, if the status indicator is green and no alerts are posted, several other factors could be affecting the quality of your connection.

• Restart your router – Often the easiest and quickest way to resolve connectivity issues.
• Network bandwidth – Avoid other bandwidth-heavy applications on your network while playing online, including but not limited to streaming music or video content, or downloading files.
• Wired connections – You will achieve optimal performance when playing an online game over a wired Ethernet connection. Wi-Fi connections have a wide variance in reliability and bandwidth, and can dramatically affect the quality of online gameplay. Wired connections will maintain the minimum bandwidth connection that is required for online gaming.

Test your home networking
The following tests require you to log in to the router on your home network to troubleshoot your network. You will need your router’s login credentials to proceed. If you do not have your router’s login credentials, you will need to contact your Internet Service Provider.

These tests refer to options that are typically found in a router’s menu. If you cannot find what you’re looking for, please refer to your router’s manual.

You may not need to perform all of these tests, so be sure to test the game after attempting each one.

If you are on an institutional (school), corporate, or other shared network, please refer to your network administrator for further assistance.

Test 1: Universal Plug and Play

• Turn Port Forwarding off (if it is turned on) and enable Universal Plug and Play (UPnP).

Test 2: Port Forwarding

• Turn UPnP off.
• Turn Port Forwarding on. Learn more about Port Forwarding.
