League of Legends Ping & Packet Loss Test

"Attempting to Reconnect"? Abilities delaying? Missing easy CS?

League of Legends servers run at 30Hz. Your client sends small, 120-byte updates to Riot's servers 30 times every second. Because mobas require precise clicking, a dropped packet at the wrong millisecond means your Flash doesn't go off, or you walk straight into a skillshot. Standard speed tests will tell you your internet is fine because they only test bandwidth. Our tool mimics exact 30Hz LoL traffic to find the hidden packet loss ruining your ranked games.

30 Hz one update every 33.3 ms

What this test sends: 30 packets per second of 120 bytes, matching League of Legends rather than a generic ping. verified

Riot has stated the League server loop runs at 30 Hz; the client interpolates between those updates.

How to Read the LoL Network Graph

Run the 30Hz test above for at least 60 seconds. Here is what your results mean for League of Legends:

Red Lines (Packet Loss)

Red vertical lines mean your connection dropped data. In LoL, this causes "ignored inputs." You press your ultimate, but nothing happens. Severe packet loss triggers the dreaded "Attempting to Reconnect" overlay in the middle of a teamfight.

High Jitter (Stability)

Jitter measures ping fluctuations. If your ping constantly jumps between 30ms and 90ms, your champion will start "moonwalking" or sliding. Last-hitting minions becomes incredibly difficult because the delay changes on every auto-attack.

High Ping (Latency)

High baseline ping gives you a permanent reaction time penalty. If you have 100ms ping, dodging fast abilities like a Malphite ultimate or a Blitzcrank hook becomes mathematically impossible, even if you click in time.

How to Fix League of Legends Lag Spikes

If the tool above shows packet loss or high jitter, try these specific fixes.

1. Ditch the Wi-Fi

The Symptom: Champion sliding or random ping spikes.

Wi-Fi signals drop packets constantly due to walls and interference. MOBA games require a perfectly steady stream of data to track your rapid movement clicks.

Fix Plug a Cat6 Ethernet cable directly from your router to your PC. This is the single most effective fix for LoL jitter.

2. Change Your DNS Servers

The Symptom: Client failing to load or randomly disconnecting from chat.

Sometimes your ISP's default DNS struggles to resolve Riot's login and chat servers quickly.

Fix Open your Windows Network settings and change your IPv4 DNS to Cloudflare (1.1.1.1) or Google (8.8.8.8).

3. Fix Bufferbloat (Home Congestion)

The Symptom: Massive lag spikes when someone else is home.

Your LoL packets are waiting in line behind a roommate's Netflix stream or a background Windows update. Your router is bottlenecking the data.

Fix Log into your router settings and enable QoS (Quality of Service). Prioritize your PC's gaming traffic over everything else.

4. Riot Direct Routing Issues

The Symptom: Ping is high in LoL, but Discord and other games are totally fine.

Riot uses a private internet backbone called "Riot Direct." Sometimes, your ISP takes a terrible, inefficient route to connect to Riot's network in Chicago (NA) or Frankfurt/Amsterdam (EUW).

Action Use our server map above to test routing. If the route is bad, a gaming VPN can force your traffic down a cleaner path to the Riot servers.

Frequently Asked Questions

Why do I get "Attempting to Reconnect" with good internet?

Internet speed (bandwidth) does not equal stability. The "Attempting to Reconnect" error is caused by 100% packet loss for a few seconds. Your ISP dropped the connection to Riot's server, even if your download speeds are fast. Check the graph above for red lines.

What is a good ping for League of Legends?

For ranked play, a ping under 40ms is ideal for dodging skillshots. However, stability matters most. Playing at a steady 60ms is infinitely better than playing at 20ms with lag spikes that jump to 80ms (high jitter).

Why did my ability or Flash not go off?

This is caused by packet loss. You pressed the key, your keyboard registered it, but the data packet was dropped by your router or ISP before it reached the Riot server. Using a wired Ethernet cable usually stops this completely.

Why is my ping high in LoL but fine on Discord?

Discord and League of Legends use entirely different server locations and routing paths. Your ISP might have a very fast route to a local Discord server, but a highly congested or broken route connecting to Riot's servers in Chicago or Frankfurt.
