Lag in League of Legends can turn a normal match into a frustrating experience, with delayed abilities, champions jumping across the screen, missed skillshots, disconnects, or sudden increases in ping during important fights.
Lag in League of Legends can come from high latency, packet loss, unstable Wi-Fi, ISP routing, background downloads, DNS problems, server-side incidents, or even PC performance issues that players mistakenly identify as network lag.
Lag in League of Legends describes delays or interruptions between your actions and what happens in the match. The first step toward fixing it is identifying whether the problem comes from the network, your computer, the Riot client, or an external server or routing issue.
Lag in League of Legends: What Is Actually Causing It?
The word “lag” is often used for every performance problem, but different symptoms require different solutions. Low FPS, high ping, packet loss, and server disconnections are not the same problem.
Knowing which one you are experiencing can prevent hours of unnecessary troubleshooting.
Network lag vs FPS lag
Network lag affects communication between your computer and the League of Legends server.
Typical signs include:
- Abilities activating late;
- Champions teleporting or rubber-banding;
- Delayed movement commands;
- Sudden reconnecting messages;
- Ping increasing dramatically;
- Actions registering seconds later.
FPS problems, on the other hand, affect how smoothly your PC renders the game.
If your camera feels choppy but commands still register immediately, you may have a graphics or hardware problem rather than a network issue.
Riot separates connection troubleshooting and frame-rate troubleshooting in its support documentation for exactly this reason.
Check your ping before changing anything
League of Legends lets you display latency and FPS during a match. The default shortcut is Ctrl + F, which displays your current frame rate and ping information.
Watch the number during normal gameplay.
If you usually play at 40 ms and suddenly jump to 180, 300, or higher, that strongly suggests a network-related issue.
If ping remains stable while FPS falls from 144 to 40, troubleshoot PC performance instead.
League of Legends High Ping Explained
League of Legends high ping means data is taking longer than expected to travel between your device and the game server.
Ping is measured in milliseconds, and lower values generally mean faster communication.
What is a good League of Legends ping?
There is no universal cutoff because physical distance to Riot’s servers differs by region. As a practical reference:
| Ping | Typical Experience |
| Under 30 ms | Excellent |
| 30–60 ms | Very responsive |
| 60–100 ms | Generally comfortable |
| 100–150 ms | Delay may become noticeable |
| 150–250 ms | Significant latency |
| 250+ ms | Gameplay can feel heavily delayed |
Consistency is just as important as the average.
A stable 70 ms connection can feel much better than a connection alternating between 25 and 220 ms every few seconds.
Fast internet does not guarantee low ping
A 500 Mbps connection can still have poor latency.
Bandwidth determines how much data your connection can transfer, while latency measures how long data takes to reach its destination and return.
Your ping can therefore be affected by:
- Physical distance;
- ISP routing;
- Congestion;
- Wi-Fi interference;
- Packet loss;
- Network saturation;
- Routing between providers.
This is why upgrading your internet package does not automatically solve League of Legends connection issues.
How to Fix Lag in League of Legends
If you are searching for how to fix lag in League of Legends, start with simple tests and change one thing at a time.
This lets you identify the real cause rather than accidentally fixing the problem without knowing why.
1. Restart your modem, router, and PC
Restarting network equipment can clear temporary connection problems and establish a fresh session with your ISP.
Turn your modem and router off, wait briefly, reconnect them, and then restart your computer.
After everything is online again, enter a normal match or Practice Tool and watch your ping.
Do not judge the result only from the Riot client because the actual game connection is what matters.
2. Use Ethernet instead of Wi-Fi
A wired connection is one of the easiest ways to eliminate wireless interference as a cause.
Wi-Fi can be affected by:
- Distance from the router;
- Walls;
- Other wireless devices;
- Crowded channels;
- Weak signal;
- Multiple devices using the network.
If the problem disappears with Ethernet, your League of Legends installation is probably fine. The wireless connection becomes the main area to investigate.
League of Legends Lag Spikes
League of Legends lag spikes happen when latency is normally acceptable but suddenly jumps for a short period.
These spikes can be more disruptive than consistently moderate ping because they are unpredictable.
What causes sudden ping spikes?
Common causes include:
- Someone starting a large download;
- Cloud synchronization;
- Streaming;
- Wi-Fi interference;
- ISP congestion;
- Packet loss;
- Router overload;
- Background game updates;
- Unstable routing.
An upload can be just as problematic as a download.
Cloud backups, video uploads, or file synchronization can saturate your upstream bandwidth and make League commands feel delayed.
Monitor when the spikes happen
Look for patterns instead of testing randomly. Ask yourself:
- Does it happen only at night?
- Does it happen when another person streams video?
- Does it happen on Wi-Fi but not Ethernet?
- Does it affect every match?
- Does it begin after several hours?
- Are other online games affected?
Patterns can quickly narrow down the likely cause.
If every online service becomes unstable at the same time, the problem is less likely to be specific to League.
League of Legends Packet Loss
League of Legends packet loss occurs when some of the data traveling between your computer and the server fails to arrive correctly.
Even small amounts of unstable packet loss can create noticeable gameplay problems.
What packet loss looks like
Possible symptoms include:
- Rubber-banding;
- Short freezes;
- Delayed attacks;
- Characters moving unpredictably;
- Random reconnecting;
- Actions not registering;
- Sudden ping fluctuations.
Riot generates network logs for matches specifically because those files can help diagnose issues such as lag, rubber-banding, and disconnections.
Persistent packet loss should not be ignored just because your speed test reports high bandwidth.
Test another connection
One useful diagnostic step is temporarily testing a different connection.
For example:
- Home internet;
- Mobile hotspot;
- Another ISP;
- Wired connection;
- Different router.
If the same PC runs League normally on another network, your original connection or route becomes a stronger suspect.
This does not mean a mobile hotspot should become your permanent gaming setup. It is simply a useful comparison.
League of Legends Connection Issues After an Update
League of Legends changes frequently, and Riot’s current patch cycle continues throughout 2026. Patch 26.19 was published on September 22, 2026, following Patch 26.18 on September 9.
When a problem begins immediately after a game or client update, do not automatically assume your ISP suddenly became worse.
Restart the Riot Client completely
Close League and the Riot Client instead of simply returning to the desktop. Check Task Manager and make sure unnecessary Riot or League processes are not stuck in the background before reopening the client.
A full PC reboot is also useful after larger updates. This clears processes, reloads drivers, and ensures pending system changes are applied.
Do not confuse client lag with in-game lag
The Riot Client can occasionally feel slow while the actual match remains responsive.
Likewise, you can have a perfectly responsive client while the game connection experiences high latency.
Test both separately. The client loading slowly is not enough evidence that your network route to a League match server is bad.
Close Background Programs Before Playing League
League of Legends does not need enormous bandwidth, but other applications can saturate your connection.
This becomes particularly important in homes where several devices share one internet connection.
Stop bandwidth-heavy activity
Before testing, pause:
- Steam downloads;
- Windows updates;
- Cloud backups;
- OneDrive or Google Drive synchronization;
- Video uploads;
- Torrents;
- Livestreaming;
- Large file transfers.
Then play another match and compare your latency.
If the issue disappears, network saturation was likely contributing.
Check other household devices
The cause may not be your own computer.
Smart TVs, consoles, phones, tablets, security cameras, and other PCs can all consume bandwidth.
A family member starting a large console update may explain why your League of Legends high ping appears at seemingly random times.
Modern routers with traffic-monitoring features can help identify heavy users.
Can Changing DNS Fix League of Legends Lag?
Riot currently recommends public DNS services as one possible connection troubleshooting step and specifically mentions services from Google and Cloudflare. Riot notes that alternative DNS servers may improve stability, speed, or reliability in some situations.
However, DNS is frequently misunderstood in gaming discussions.
DNS does not directly control every game packet
DNS primarily helps your device translate domain names into addresses.
Once the actual game connection has been established, your traffic follows internet routing paths determined by network infrastructure.
Changing DNS therefore should not be treated as a guaranteed method to reduce every player’s in-game ping.
It may help when the ISP’s DNS infrastructure is unreliable, but routing and congestion remain separate issues.
Test instead of assuming
If you change DNS, compare your connection before and after.
Useful options mentioned by Riot include public DNS services from Google and Cloudflare.
If nothing changes, restore your original configuration or continue troubleshooting elsewhere.
Avoid stacking multiple network changes at once because you will not know which modification affected the result.
Check Riot Server Status Before Troubleshooting Your PC
Sometimes the problem affects many players rather than your individual connection.
Maintenance, authentication problems, routing incidents, or regional server issues can temporarily interfere with League.
Look for widespread reports
Before changing advanced Windows settings, check whether other players in your region are experiencing the same symptoms.
Signs of a broader issue include:
- Login failures;
- Matchmaking problems;
- Multiple friends disconnecting;
- Large spikes affecting an entire match;
- Official maintenance notices;
- Widespread recent reports.
For example, scheduled maintenance on September 16, 2026 caused login and launching problems for players in North America.
A server-side event cannot be fixed by reinstalling your network drivers.
Avoid unnecessary changes during an outage
If Riot is experiencing an incident, avoid immediately:
- Reinstalling League;
- Reinstalling Windows;
- Resetting your router;
- Changing dozens of Windows settings;
- Replacing hardware.
Wait until the service issue is resolved and test again. Otherwise, you can create new problems while trying to fix something outside your control.
Lag in League of Legends vs Low FPS
This distinction deserves special attention because many players call both problems “lag.”
The correct solution depends entirely on which one you have.
Network lag affects commands
If your champion responds late to commands but the animation itself remains visually smooth, your problem is probably network-related.
Network symptoms include:
- Delayed spells;
- Rubber-banding;
- High ping;
- Reconnecting;
- Teleporting champions;
- Late damage registration.
These should lead you toward connection troubleshooting.
FPS lag affects visual smoothness
Low FPS produces:
- Choppy camera movement;
- Slow visual rendering;
- Frame drops;
- Stuttering effects;
- Poor performance during team fights.
Riot maintains separate documentation for frame-rate troubleshooting because these problems involve hardware, drivers, background software, or game settings rather than network latency.
Always display both FPS and ping when diagnosing the issue.
Advanced League of Legends Connection Troubleshooting
If basic fixes do not work, move to deeper testing instead of changing random registry settings or downloading questionable “ping boosters.”
The goal is to isolate where the connection becomes unstable.
Update your network adapter driver
Network drivers can become outdated or corrupted. Use the official website for your motherboard, laptop, or network adapter manufacturer rather than downloading drivers from unknown websites.
After updating:
- Restart Windows.
- Launch League.
- Enter Practice Tool.
- Display ping with Ctrl + F.
- Play a normal match.
- Compare the results.
One short test is not enough if your problem normally appears intermittently.
Use Riot’s logs when the problem persists
League creates network logs for each match, and Riot specifically identifies them as useful for troubleshooting lag, rubber-banding, and disconnections.
If you cannot identify the problem yourself, these logs can be useful when working with Riot Support.
This is far more informative than simply telling support that “the game is lagging.” Include the time of the affected match and describe exactly what happened.
Best Troubleshooting Order for League of Legends Lag
A structured process prevents you from wasting time. Start with the easiest and safest tests.
Follow this order
Use this sequence:
- Display ping and FPS with Ctrl + F.
- Determine whether the issue is network or FPS related.
- Restart your modem, router, and PC.
- Test Ethernet instead of Wi-Fi.
- Stop downloads, uploads, and cloud synchronization.
- Check other devices on your network.
- Check Riot’s service status.
- Test another internet connection if possible.
- Try a public DNS if appropriate.
- Update network drivers.
- Investigate packet loss and routing.
- Collect Riot network logs if the problem remains.
Change one major variable at a time. That makes the diagnosis much more reliable.
Can ExitLag Help With Lag in League of Legends?
ExitLag focuses on network route optimization rather than increasing FPS or changing League’s graphics performance.
This makes it most relevant when the problem involves the path your traffic takes toward the game server.
ExitLag targets routing and connection stability
Internet traffic can travel through several networks before reaching Riot’s infrastructure.
The default route selected by your ISP is not always the most efficient or stable available path.
ExitLag analyzes alternative routes for supported games and can help reduce problems associated with:
- High ping;
- Packet loss;
- Routing instability;
- Connection fluctuations.
Results vary based on location, ISP, network conditions, and game server.
ExitLag cannot fix every type of lag
ExitLag cannot repair:
- Low FPS;
- GPU problems;
