Do you experience packet loss on League of Legends?

League of Legends is among the leading online games in the world, with over 200 million active users. It is one of the best MOBA games and regularly hosts tournaments and world championships. 

Being a very popular game, we’d think that League of Legends is flawless. Sadly, this is not the case. Like other titles, it can suffer from downtimes and errors. 

One of the most common problems with League of Legends and other online games is packet loss. This occurs when one or more packets of data traveling across a network fail to reach their destination. 

Most of the time, this issue is caused by a slow or unstable internet connection. On the other hand, it can also be due to third-party apps, improper user configurations, or server-related problems. 

In this guide, we will show you how to fix packet loss on League of Legends. 

Let’s dive right in!

1. Restart Your Computer.

2. Close Online Applications. 

Being an online game, League of Legends requires stable internet to connect you with other players. If you encounter packet loss, it’s possible that other applications on your computer are consuming bandwidth. 

To avoid issues, we suggest closing unused applications to give more space for League of Legends to operate.

4. Turn Off VPN. 

Virtual private networks are third-party applications that protect your online data from hackers and websites that track your activity. While they work great for the most part, they can also cause issues with your network. 

If you encounter packet loss on League of Legends, try disabling your VPN before joining a game.

PureVPN also works well with streaming services like Netflix, Disney+, and HBO Max. 

5. Update Network Drivers.

7. Use A Wired Connection. 

If you are connected to a wireless connection, you can try switching to a wired connection. Compared to Wi-Fi, a good old ethernet cable will provide a much more stable internet connection, which is crucial for any online game. 

Ethernet cables can also deliver faster internet speeds, which allows you to utilize the full potential of your connection.
