Known Lag Problems
These problems are reported by real players. If your region or ISP is listed, a network optimizer is likely to help.
North America (West Coast after Chicago move)
50-80ms from West Coast- West Coast players saw ping increase from ~20ms to 50-70ms after 2015 server move to Chicago
- Some ISPs route poorly from California/Washington to Chicago — adding 20-30ms over optimal
- Riot Direct backbone helps but cannot fix every ISP's last-mile routing
Southeast Asia (Philippines/Indonesia)
30-100ms to Singapore- Players from Philippines and Indonesia connecting to Singapore server experience variable latency
- PLDT and Globe routing to Singapore can be inconsistent, especially during peak hours
- SEA server consolidation in January 2025 increased population but some players report higher ping than the old local servers
Russia (Eastern regions)
40-200ms depending on location within Russia- RU server is physically in Munich, Germany — not in Russia
- Players in Siberia and Far East Russia get 100-200ms+ to their 'home' server
- Some eastern Russian players get better ping to JP or KR servers
Latin America (Colombia, Venezuela)
60-150ms- LAN server in Miami means traffic from South American countries routes north through international links
- Colombian players get 60-100ms to Miami vs potential <40ms if server were in Bogota
- Venezuelan players face 80-150ms due to poor international infrastructure
What players commonly report
- Lag spikes during evening peak hours (ISP congestion)
- West Coast NA ping increase after Chicago server move
- SEA server consolidation increased latency for some Philippine/Indonesian players
- Vanguard compatibility issues with some hardware drivers
- Packet loss causing ability input drops during team fights
How to Fix It
Try these first — they're free and solve the problem for most people.
01 Switch to Ethernet and disable WiFi
1. Connect your PC directly to your router with an Ethernet cable 2. In Windows Settings > Network & Internet, disable the WiFi adapter 3. Launch League of Legends and check ping with Ctrl+F 4. Compare to your previous WiFi ping — should be lower and more stable
Eliminates 2-10ms of WiFi latency and removes wireless packet loss. The single most impactful change for WiFi users. Especially important during team fights where jitter spikes on WiFi cause ability delays.
02 Use Riot's Hextech Repair Tool
1. Download from https://support-leagueoflegends.riotgames.com/ 2. Run the tool and select your League of Legends installation 3. Choose 'Force Repatch' or 'Reset Network' depending on your issue 4. The tool will repair game files and reset network configuration 5. Restart and test
Fixes corrupted game files and network settings. Riot's official tool for connection troubleshooting — good first step before more advanced fixes.
General network tips (not League of Legends-specific)
03 Use Ctrl+F to display ping and FPS in-game
1. Launch a League of Legends match (any mode works) 2. Press Ctrl+F on your keyboard 3. A small overlay appears in the top-right corner showing MS (ping) and FPS 4. Watch the MS value during laning, team fights, and idle phases 5. If MS spikes during team fights but FPS stays stable, it's a network issue 6. If FPS drops but MS is stable, it's a hardware/client issue
Doesn't fix anything — but shows you exactly where the problem is. Essential first step before trying any other fix.
04 Flush DNS and reset Winsock
1. Open Command Prompt as Administrator 2. Run: ipconfig /flushdns 3. Run: netsh winsock reset 4. Restart your PC 5. Launch League of Legends and check if ping improved
Fixes routing issues caused by stale DNS entries or corrupted network state. Quick fix that often resolves sudden ping increases that appeared after a patch or system update.
05 Close bandwidth-heavy background applications
1. Open Task Manager (Ctrl+Shift+Esc) 2. Go to the Network column — sort by network usage 3. Close or pause: browser downloads, streaming (Twitch, YouTube), cloud sync (OneDrive, Dropbox, Google Drive), game launchers updating other games 4. Queue into a match and check if ping stabilized
Prevents bandwidth competition. Even on fast connections, a Windows Update or Steam download can saturate your upload, causing packet loss in League.
06 Set QoS priority on your router for LoL traffic
Access router admin panel and enable QoS. Prioritize UDP traffic on ports 5000-5500 or prioritize League of Legends.exe by application if supported.
Ensures game packets are processed first, even when other devices are using bandwidth
Regions with good connectivity
Players in these regions likely won't benefit much from a network optimizer.
- Western Europe — EUW (Amsterdam) provides excellent coverage for Western Europe. Most ISPs in Germany, France, UK, Netherlands, Benelux have good peering with Riot Direct. Typical ping 10-40ms.
- South Korea — KR server in Seoul provides sub-10ms for most Korean players. Excellent infrastructure with PC bang culture ensuring strong peering. The most competitive LoL server.
- US East Coast — After the 2015 Chicago move, East Coast players enjoy 20-40ms. Significant improvement from the Portland era where East Coast players suffered 100ms+.
- Brazil (major cities) — Sao Paulo server provides 10-30ms for players in major Brazilian cities. Strong local CBLOL esports scene.
Still lagging? The problem is likely your ISP's routing to the game servers.
