2. Check your server current status

First and foremost, you should check the external source that can cause connectivity problems. In particular, the closest server status. You can do that by following this link and selecting the server you used to connect to. If the server is active, we can move on to internal issues.

Switch to LAN cable instead of Wi-Fi

Wi-Fi connection will work well for web browsing or social media. However, online gaming requires wired connections in order to experience stable FPS without annoying spikes.

So, if there is a possibility to connect to a wired connection, do so.

Make firewall exception or disable the firewall

firewall is a security measure that protects your PC from both outgoing and incoming unwanted communications. In other words, the first line of defense. Nevertheless, sometimes it blocks applications that are harmless.

This can be a reason for connectivity problems with any online multiplayer. In this case, League of Legends.

Your best bet to overcome this problem is by adding a firewall exception for LoL executable files or even disabling the firewall altogether. The second option is not advised but trying it out can at least give you heads-up of what is going on.

To add firewall exceptions for League of Legends, follow these instructions:

  1. Go to Control Panel.

  3. Click Windows Firewall.
  4. Select Allow an app or feature trough Windows Firewall.
  5. In the given list you should find 2 League of Legends executables.

  8. To do so, choose Change Settings and click Allow another app.
  9. The default location of two executables are :
    • C:/Riot Games/League of Legends/lol.launcher.exe
    • C:/Riot Games/League of Legends/RADS/systemrads_user_kernel.exe
  10. Add both to your firewall exceptions list and click OK.

To disable your Windows Firewall, follow the path:

  1. Go to Control Panel.
  2. Choose System and Security.
  3. Click Windows Firewall.
  4. Select Turn Windows Firewall on or off.
  5. You’ll need administrator privileges to turn it off.

  1. Press the Windows Key (the key on the left side of the spacebar, between ctrl and alt).
  2. Type cmd
  3. Right-click the Command prompt shortcut and select “Run as Administrator” from the drop-down menu. You should now see a black window with white letters.
