Hello! It seems you're experiencing connectivity issues with Overwatch when using your Deco router. Since you're able to play the game when directly connected to fiber without the router, it's possible that the Deco settings are causing the problem. To troubleshoot, try the following:

1. Check Firewall Settings: Make sure that the Deco router's firewall settings are not blocking Overwatch's connection. You may need to allow the necessary ports or create a specific rule for the game.
2. Enable UPnP: Enable Universal Plug and Play (UPnP) in your Deco router settings. This feature helps devices establish connections more easily.
3. Update Firmware: Check if there's a firmware update available for your Deco M9 Plus router. Updating to the latest firmware version can sometimes resolve compatibility issues.
4. Contact Support: If the issue persists, reach out to Deco support for further assistance. They can provide more specific guidance or escalate the issue if necessary.

Hope this helps resolve the problem and gets you back into the Game smoothly!
