By following these quick troubleshooting steps, you can fix most high ping issues in League of Legends. Each action improves your connection and helps you enjoy smoother gameplay.

Checking Ping and Connection Quality

In-Game Ping Display

You need to monitor your ping during every match. League of Legends gives you a simple way to do this. Press Ctrl + F while you play. This shortcut shows your current ping and FPS in the top right corner of your screen. You should always keep an eye on your ping. If you see the number jump or stay high, you know there is a problem with your network connectivity.

Tip: If you ask, “How do I check my ping in League of Legends?”—just use Ctrl + F during a game.

You can also use the command prompt on your computer to test your ping. Open CMD and type ping [server IP address] -t. This command lets you watch your ping in real time. You will see if your network connectivity drops or if your ping spikes during your session.

Acceptable Ping Levels

For the best experience in League of Legends, you want your ping to stay low. Most competitive players agree that a ping below 40 ms is ideal. This level lets you react quickly and play at your best. If your ping goes above 40 ms, you may notice delays in your actions. Even a small increase can affect your gameplay. Try to keep your ping as low as possible for smooth matches.

Ping (ms)

Gameplay Quality

0-40

Excellent (No delay)

41-60

Good (Minor delay)

61-100

Playable (Noticeable lag)

100+

Poor (Significant lag)

If you see your ping rise above 100 ms, you will likely face lag and slow responses. Always aim for the lowest ping you can get.

Using External Tools

You have more options to check your ping and network connectivity outside the game. Several online tools help you measure your ping and diagnose problems.

  • League Ping Test: This tool checks your ping to League of Legends servers. It also gives you tips to fix issues.

  • LoL Server Ping Test: Use this tool to find out if your connection to the server is stable. It helps you spot problems before you start a match.

Online ping test websites also give you a quick look at your internet speed and latency. Use these tools if you want to double-check your ping or if you think your network connectivity is unstable.

Note: Regularly checking your ping helps you catch problems early and keeps your gameplay smooth.

Identifying High Ping Symptoms

Signs of High Latency

You can spot high ping and high latency in League of Legends by watching for certain signs during your matches. These symptoms often appear when your internet connection struggles to keep up with the game’s demands.

  • You notice lag spikes, especially during intense battles or team fights.

  • Your champion’s actions feel delayed after you press a key or click.

  • The game experience feels inconsistent, with smooth moments interrupted by sudden spikes in response time.

  • You see your ping number jump or stay high on the in-game display.

  • Commands do not register right away, making it hard to dodge skill shots or escape danger.

High ping creates a clear delay between your actions and what you see on the screen. For example, if you try to flash away from an enemy’s ultimate and your champion moves half a second late, high latency is likely the cause. Even a small delay can change the outcome of a fight. You need to recognize these signs early so you can fix your connection before it affects your rank.

Tip: Always check your ping during matches. If you see lag spikes or delays, take action right away.

Common Lag Issues

Many players on the US server report similar lag problems. High ping and lag spikes often come from a few main sources:

  • Internet Service Provider issues, such as network congestion or routing problems, can cause high ping.

  • Wi-Fi connections are less stable and often lead to lag spikes.

  • Geographic distance from the game server increases high latency and high ping.

  • Background applications or other devices using bandwidth can trigger lag spikes.

  • Outdated network drivers or hardware may result in high ping and lag.

  • Server-side problems with League of Legends can affect many players at once.

Lag in League of Legends usually means your internet connection is not performing well. If you see high ping and lag spikes, you know your connection needs attention. Sometimes, lag happens even when your ping looks normal. This can mean you have packet loss or an unstable connection, which also causes lag. You should always try to find the source of high latency so you can enjoy smoother games.

Advanced Troubleshooting Steps

If you still experience high latency after basic fixes, you should try these advanced troubleshooting steps. These methods target deeper network and game issues that often cause persistent lag.

Change DNS Settings

Changing your dns settings can improve your connection to the game server. The dns server translates website names into IP addresses. A faster dns server can help your device connect to the League of Legends server more quickly. This step often leads to lower latency and smoother gameplay. You can switch to public dns servers like Google (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1). Open your network settings, find the dns section, and enter the new addresses. Restart your device after making changes. Many players notice a drop in ping after updating their dns.

Tip: Changing dns can also help if your wi-fi connection feels slow or unstable during a game.

Configure Firewall and Port Forwarding

Your firewall can block important game traffic. You need to allow League of Legends through your firewall and set up port forwarding for the best network performance. This ensures the game can send and receive data without interruptions.
