Let me explain how to fix League of Legends packet loss with proven solutions that work.
I'll start with the most effective methods.
Switch to a wired connection first. Remove your WiFi connection and plug your computer directly into your router with an ethernet cable. This gives you a stable connection without walls or furniture blocking signals.
Check your network cables next. Old or damaged cables cause packet loss.
Replace any cables with bends or joints. Make sure to use new cables every five years for best performance.
Close background programs that use internet. Every download and program takes bandwidth from your game. Pause downloads and close unnecessary applications while playing League.
Forward these specific ports for League:
- TCP: 2099, 5222-5223, 8088, 8393-8400
- UDP: 5000-5500, 8088
Your internet speed matters too. You need at least 5-6 megabytes per second for smooth gaming. Consider upgrading your internet plan if you have less speed than this.
Old routers can cause problems. If your router is over seven years old, consider replacing it. Test your router at a friend's house to check if it causes issues on other networks.
Getting a separate internet connection helps if you share internet with others. Other people's downloads and streaming can cause your packet loss. A dedicated connection gives you stable gameplay.
I recommend starting with the wired connection and port forwarding. These two changes often fix packet loss immediately. Then work through the other solutions if needed.
Remember to restart your router and computer after making these changes. This ensures all new settings take effect properly.
