World of Warcraft® Connection and Latency Troubleshooting

Keywords: 113, 122, 144, 21014, 105, connection, connect

If you are not able to connect to World of Warcraft®, or if you are experiencing high latency or frequent disconnects while playing the game, please follow the steps below to resolve the issue.

Windows

  1. Check the Realm Status page and the Service Status Forum for the game server status before you try more advanced troubleshooting steps. If the servers are offline, try again later. If the servers are available, continue troubleshooting.

    Note: Error 122 and error 144 may also appear when servers are not available. Error 113 means the login server is currently busy. Try again later.

  2. Compatibility issues or data corruption in user interface (UI) files may cause high latency or disconnections, as the game client will keep retrying tasks that fail because of such UI issues. Reset your UI to create new, up-to-date interface files.
  3. World of Warcraft requires an up-to-date operating system and current hardware drivers in order to run properly. Be sure that your operating system and drivers are fully updated.
  4. Over time, some network devices may become flooded with data which can prevent them from maintaining stable connections to the Internet. Power cycle your modem and router to reset them and reestablish their connection to your ISP.
Advanced Troubleshooting
  1. Make sure that your Firewall and Router are properly configured for World of Warcraft.
  2. Wireless or low-speed internet connections may not be able to support World of Warcraft. If you’re using one of these connections, try optimizing your internet connection to improve your connection.
  3. Conflicting network information may cause connection issues. Try to release and renew your IP and flush your DNS to resolve any conflicts.
  4. Programs running in the background can negatively affect World of Warcraft's performance. Close any running background applications.
  5. Some network card settings may cause high latency in World of Warcraft. Check your network card’s settings and change any that are not properly configured.
  6. If your latency is fine until other members of your household start using the internet, your router may be having trouble handling all the traffic. Your router might need a firmware upgrade, or it might need to be replaced. Contact your router’s manufacturer for assistance.
