How to Fix League of Legends Lag

Why League of Legends feels laggy

League is relatively tolerant of latency up to ~80 ms, but packet loss is brutal. Even 1% loss causes skillshots to register late and auto-attacks to drop. Map-wide pings and spell queues feel 'off' long before the ping number looks bad.

Target numbers for League of Legends

Step-by-step fix

1. Run a wired Ethernet speed test

Before changing anything, measure your baseline on a wired connection. Record ping, jitter, and packet loss — those three are what matter for League of Legends. Run a speed test now.

2. Switch off Wi-Fi during matches

Even a strong Wi-Fi signal adds 5–20 ms of jitter on top of whatever your line already has. A wired Ethernet cable is the single biggest lag reducer for most home gamers. See our Wi-Fi vs Ethernet comparison.

3. Close bandwidth-hungry background apps

Cloud sync (Dropbox, OneDrive, iCloud), streaming on other devices, and auto-updating games will eat your upload bandwidth during matches. Pause them before queuing up. Our background apps guide has the full checklist.

4. Pick the closest server region

Riot's direct-to-server network on League is separate from the Valorant one. If one game lags and the other is fine, the issue is route-specific, not your ISP.

5. Test for packet loss

Run a packet-loss test during a match. Any loss above 0.5% is enough to cause visible rubber-banding and hit-registration problems in League of Legends.

6. Rule out bufferbloat

If your line is fast but games feel laggy specifically when others are streaming, you have bufferbloat. QoS settings on a better router will fix it.

Frequently Asked Questions

What is a good ping for League of Legends?

Aim for under 60 ms for competitive MOBA play in League of Legends. Casual play is fine up to roughly 120 ms, but hit registration and input feel degrade noticeably past that.

How much internet speed do I need for League of Legends?

League of Legends itself uses very little bandwidth — roughly 2 Mbps down and 1 Mbps up during gameplay. If multiple people share your connection, add 5–10 Mbps per active 1080p stream to avoid competing for bandwidth.

Why does League of Legends lag when my internet is fast?

Speed (bandwidth) and latency are different metrics. A 1 Gbps line can still have terrible lag if ping, jitter, or packet loss are high. Run a speed test on wired Ethernet and check the ping and jitter numbers — those are the ones that matter for gaming.

Will a VPN reduce my game lag?

Only if your ISP is routing you poorly to the League of Legends server. A gaming VPN can sometimes shave 20–40 ms by forcing a better route — but it adds at least 5 ms of overhead, so it is a gamble. Try first without, then test with.
