How do I fix my disconnect/lag issues?

If you are having frequent issues with disconnects or lag in your games, there are a few things you can try that might improve your connection. 

  1. Clear your cookies and cache regularly! This is the most common fix for any issues of slowness on your computer. See the steps to clear your internet cache here. After you’ve done this, close all browser windows (not just a few tabs, the whole browser!) and re-open chess.com.
  2. Pause any downloads or uploads on your computer. If you are downloading a large file, this takes up bandwidth and can cause lag!
  3. Close any other browser tabs that are streaming content. Streaming video or music uses bandwidth just like downloading a large file does. If you’re having connection problems, try pausing your streaming while you play chess. 
  4. Disable browser extensions. Sometimes these use a lot of memory, or alter the JavaScript or other files used by chess.com, or alter your connection in some way. It's best to disable them while playing!
  5. Check Task Manager to see if any programs are using up a lot of memory, and close them while you play chess. 
  6. If you have a high number of browser tabs open, try closing all tabs except chess.com. Even if you aren’t streaming or downloading, each tab takes up some of your computer’s memory. 
  7. Make sure your browser is updated to the most current version. If you are using Internet Explorer, you may want to try using Chrome or Firefox instead. 
  8. Optimize your communication with our server using our live chess settings. We have made available multiple kinds of connections for our users in order to best accommodate the different kind of browser, router and ISP setups.  For instructions on how to toggle these settings, read here.
  9. Try using a Wired Connection. Sometimes it is an unstable WiFi connection causing the issue. Try being closer to your router, or even using a wired connection.

If you are still having connection issues after all of the above, please contact your internet service provider. You may need a faster connection. Chess.com servers will cancel out up to 1000ms (1 second) of lag, but if your ping is much more than that you may have a hard time playing live chess.
