Improve your connection

If you frequently experience disconnects or lag during your games, please try these steps to improve your connection:

Web

Mobile

  • Clear cookies and cache: Regularly clear your browser's cookies and cache to fix slowness. Follow the steps here and restart your browser.

  • Pause downloads/uploads: Downloading large files consumes bandwidth and can cause lag. Pause these activities while playing.

  • Close streaming tabs: Streaming video or music also uses bandwidth. Pause streaming while you play chess.

  • Disable browser extensions: Extensions may use a lot of memory or interfere with Chess.com. Disable them during your games.

  • Check Task Manager: Close any programs using a lot of memory.

  • Close extra browser tabs: Even non-streaming tabs use memory. Close all except Chess.com.

  • Update your browser: Ensure you have the latest version. If using Internet Explorer, switch to Chrome or Firefox.

  • Use a wired connection: WiFi can be unstable. Try a wired connection or move closer to your router.

  • Close Other Apps: Close any other apps or programs on your device that might be using memory and system resources to ensure the app has the maximum resources available.

  • Use Wi-Fi Instead of 3G/4G: Sometimes an unstable connection can cause issues. Try being closer to your router if possible.

  • Changing your connection settings to a public DNS: If you're having trouble getting matched, this could be worth trying if other troubleshooting steps haven’t worked. Home networks usually use a DNS server provided by your Internet Service Provider (ISP). Switching to a third-party services, such as Google DNS, can improve search performance, enhance security, and strengthen your connection. You can find the steps here.

  • Update Operating Software: Ensure your device's operating system is completely updated.

  • Check Phone Memory: If your phone has very limited memory (especially less than 2 GB), this will affect the functionality and speed of your apps.

  • Reinstall the App: A fresh installation of the app can often fix issues caused by data corruption.

How to check your ping

If you are still having issues after trying the steps above, you might need to contact your internet service provider for a faster connection. Chess.com servers can handle up to 1000ms (1 second) of lag, but higher ping may affect gameplay.

Here's how you can check your ping:

  1. While on the chess.com/play/online page, click the icon at the bottom right next to the board to open the console.

  2. Type /ping in the pop-up window to check your ping.

Please note that receiving an 'offline' value when typing /ping in the in-game chat window is expected if you are playing the game on the Real Chess Network (RCN).
