League of Legends Packet Loss Fix

What Means Packet Loss?

Packet Loss is similar to the high ping or high latency that can cause game server connectivity or matchmaking issues like rubberbanding. Such an issue may occur due to a poor internet connection as a basic reason. The packet loss in League of Legends indicates the Riot game servers are unable to communicate with your IP address or server address. It basically occurs whenever a huge number of users are trying to connect to a network multiple times and having connection timeout issues.

The chances are high that poor internet connectivity, networking glitches, Wi-Fi router-related problems, server downtime, Windows firewall issues, etc can also play a major role. Fortunately, there are some workarounds mentioned below that should come in handy. So, without further ado, let’s jump into it.

1. Restart the PC

Before getting to any other conclusion, it’s highly recommended to restart the computer manually to ensure there is no temporary glitch with the system or cache data. Sometimes a normal reboot of the computer can come in handy.

2. Check the Internet Connectivity

Make sure to check your internet connection before jumping to any other conclusion because a poor or unstable internet connection can simply trigger many issues with the game launching or connecting to the game servers online. Try switching your wired (ethernet) connection to Wi-Fi (wireless) or vice versa, and then check for the networking issue again. You can also increase the internet speed by upgrading your data plan (if required) or contacting your service provider to assign a new IP address.

3. Power Cycle the Wi-Fi Router

Sometimes a normal restart of the Wi-Fi router might not come in handy. That’s why try performing a power cycle on your Wi-Fi router to check whether the problem has been fixed or not. Just turn off the router and unplug the power cable from it > Wait for at least a minute or so and connect the power cable again then turn on the router to check for the issue.

4. Check the Riot Games Server Status

You should check whether the League of Legends game server status is going well or not. Sometimes issues with server downtime or maintenance can also trigger game launching and connectivity errors. You can visit the official Riot Games Service Status webpage to cross-check the issue. You can also check the DownDetector League of Legends Status to ensure there is downtime or server issue appearing while you’re trying to play the game.

In addition, you try following the Riot Games Support Twitter handle for further info and updates about the game & server status. If in case, there is an issue with the server then make sure to wait for a couple of hours and then try again. If there is no issue with the server then head over to the next method.

5. Close Background Tasks

If your PC gets slow or the gaming performance isn’t smooth as expected then make sure to close background processes that are unnecessary for you. It can prevent plenty of CPU/RAM usage so that your game can run easily. To do so:

  • Press the Ctrl+Shift+Esc keys to open Task Manager.
  • Click on the Processes tab > Select the task that you want to close.
  • Once selected, click on End Task. Make sure to do the steps for each task individually.
  • Once done, just restart your computer to change the effects immediately.

6. Update League of Legends

7. Repair the Game Files

8. Update Network Drivers

9. Don’t Use VPN or Proxy Servers

Try not to use any kind of VPN (Virtual Private Network) or proxy servers at your end to avoid server connectivity issues whatsoever. Even if using a VPN service can help you, it can trigger higher ping latency, etc.

10. Flush DNS

It’s also possible that your Windows system has gathered plenty of DNS cache data related to the internet configuration. You can follow the steps below to easily connect with the game servers after removing the DNS resolver cache data from the system.

  • Open the Start Menu.
  • Type Command Prompt and search for it.
  • Now, right-click on Command Prompt > Select Run as administrator.
  • Click on Yes to run with the admin access > Once the command prompt window opens, type the following command and hit Enter:
ipconfig /flushdns
  • A successful message will appear that says, “Successfully flushed the DNS Resolver Cache.”
  • Restart the computer and check for the issue again.

11. Disable Energy-Efficient Ethernet

Well, the power-saving options on Windows can also trouble you a lot when it comes to networking glitches. You should follow the steps below to disable energy-efficient ethernet, green ethernet, power-saving mode, etc.

  • Open the Start Menu and search for Device Manager.
  • Open it and right-click on the Network adapter.
  • Choose Properties > Navigate to the Power Management tab.

    • Green Ethernet
    • Power saving mode
  • Once done, make sure to reboot the system to check for the issue again.

  • Press the Win+I keys to open Windows Settings.
  • Next, click on Update & Security > Select Check for updates under the Windows Update section.

  • It may take a while to complete the update.
  • Once done, restart your computer to install the update.

13. Contact Riot Games Support

If none of the workarounds did help you and the packet loss still persists then make sure to contact Riot Games Support to submit a request for whatever issue you’re facing.
