what to do if League of Legends ping spikes on Windows 10

League of Legends is a fun game to play that challenges players to take on the role of a summoner who controls a champion with unique abilities and skills.

They fight against a team of other players or AI champions to destroy the opposing team’s Nexus.

Although League of Legends launched a few years ago, it’s still affected by a series of annoying issues.

Ping spikes can be a big problem in any game, and many League of Legends players reported this issue.

Here are some common issues reported by users:

  • League of Legends lag – This can be caused by background applications on your PC, so make sure that you’re only running the game and not other network-intensive apps in the background.
  • League of Legends lag spikes, wireless – If that’s the case, we suggest to temporarily switch to a wired network and check if that helps.

In this article, we’re going to focus on the ping spikes that randomly occur on Windows 10 PCs and offer you a quick workaround that you can use to solve this issue.

Sometimes your antivirus can interfere with your system and cause problems with some applications.

To fix the issue, you need to open your antivirus settings and try disabling certain features. Be sure to disable the firewall features on your antivirus and check if that solves the problem with ping spikes.

4. Turn off the auto-connect option for Wi-Fi

In order to reduce League of Legends ping spikes, you might want to try changing a couple of Wi-Fi settings. According to users, sometimes the auto-connect feature for your Wi-Fi can cause this issue to appear.

To turn it off, simply click the Wi-Fi icon in your system tray, select the Wi-Fi network you want to connect to, and uncheck the Connect automatically option.

Now connect to the network and check if the problem with ping spikes still appears. If you can, try switching to an Ethernet connection.

Despite all its benefits, Wi-Fi connection is prone to interference, and that can drastically influence your ping.

On the other hand, wired connection offers better stability and much better protection from interference, so if you can, try using a wired connection and check if that helps with your ping.

7. Forward the required ports

In order to reduce ping spikes in League of Legends, it might be necessary to forward the required ports. Port forwarding is an advanced procedure, and in order to see how to do it properly, we advise you to check your router’s manual.

The process is different for each router, and so there are no universal guidelines. Simply log in to your router and on the configuration page locate port forwarding. Now forward the following ports:

  • 5000 – 5500 UDP (League of Legends Game Client)
  • 8393 – 8400 TCP (Patcher and Maestro)
  • 2099 TCP (PVP.Net)
  • 5223 TCP (PVP.Net)
  • 5222 TCP (PVP.Net)
  • 80 TCP (HTTP Connections)
  • 443 TCP (HTTPS Connections)
  • 8088 UDP and TCP (Spectator Mode)

After forwarding the required ports, the problem should be completely resolved.
